Installation
Install ESLint either locally or globally.
npm install --save-dev eslint
If you have installed ESLint globally, you have to install JSDoc plugin globally too. Otherwise, install it locally.
npm install --save-dev eslint-plugin-jsdoc
Configuration
Add plugins section and specify eslint-plugin-jsdoc as a plugin.
{
"plugins": [
"jsdoc"
]
}
Finally, enable all of the rules that you would like to use.
{
"rules": {
"jsdoc/check-alignment": 1, // Recommended
"jsdoc/check-examples": 1,
"jsdoc/check-indentation": 1,
"jsdoc/check-param-names": 1, // Recommended
"jsdoc/check-syntax": 1,
"jsdoc/check-tag-names": 1, // Recommended
"jsdoc/check-types": 1, // Recommended
"jsdoc/implements-on-classes": 1, // Recommended
"jsdoc/match-description": 1,
"jsdoc/newline-after-description": 1, // Recommended
"jsdoc/no-types": 1,
"jsdoc/no-undefined-types": 1, // Recommended
"jsdoc/require-description": 1,
"jsdoc/require-description-complete-sentence": 1,
"jsdoc/require-example": 1,
"jsdoc/require-hyphen-before-param-description": 1,
"jsdoc/require-jsdoc": 1, // Recommended
"jsdoc/require-param": 1, // Recommended
"jsdoc/require-param-description": 1, // Recommended
"jsdoc/require-param-name": 1, // Recommended
"jsdoc/require-param-type": 1, // Recommended
"jsdoc/require-returns": 1, // Recommended
"jsdoc/require-returns-check": 1, // Recommended
"jsdoc/require-returns-description": 1, // Recommended
"jsdoc/require-returns-type": 1, // Recommended
"jsdoc/valid-types": 1 // Recommended
}
}
Or you can simply use the following which enables the rules commented above as "recommended":
{
"extends": ["plugin:jsdoc/recommended"]
}
You can then selectively add to or override the recommended rules.
Options
Rules may, as per the ESLint user guide, have their own individual options. In eslint-plugin-jsdoc, a few options,
such as, exemptedBy and contexts, may be used across different rules.
eslint-plugin-jsdoc options, if present, are in the form of an object
supplied as the second argument in an array after the error level.
// `.eslintrc.js`
{
rules: {
'jsdoc/require-example': [
// The Error level should be `error`, `warn`, or `off` (or 2, 1, or 0)
'error',
// The options vary by rule, but are added to an options object:
{
avoidExampleOnConstructors: true,
exemptedBy: ['type']
}
]
}
}
Settings
Allow @private to disable rules for that comment block
settings.jsdoc.ignorePrivate- Disables all rules for the comment block on which a@privatetag (or@access private) occurs. Defaults tofalse. Note: This has no effect with the rulecheck-access(whose purpose is to check access modifiers).
maxLines and minLines
One can use minLines and maxLines to indicate how many line breaks
(if any) will be checked to find a jsdoc comment block before the given
code block. These settings default to 0 and 1 respectively.
In conjunction with the require-jsdoc rule, these settings can
be enforced so as to report problems if a jsdoc block is not found within
the specified boundaries. The settings are also used in the fixer to determine
how many line breaks to add when a block is missing.
Mode
settings.jsdoc.mode- Set tojsdoc(the default),typescript, orclosure. Currently is used for the following:- Determine valid tags for
check-tag-names - Only check
@templateinno-undefined-typesfor types in "closure" and "typescript" modes - For type-checking rules, determine which tags will be checked for types (Closure allows types on some tags which the others do not, so these tags will additionally be checked in "closure" mode)
- Check preferred tag names
- Determine valid tags for
Alias Preference
Use settings.jsdoc.tagNamePreference to configure a preferred alias name for a JSDoc tag. The format of the configuration is: <primary tag name>: <preferred alias name>, e.g.
{
"rules": {},
"settings": {
"jsdoc": {
"tagNamePreference": {
"param": "arg",
"returns": "return"
}
}
}
}
One may also use an object with a message and replacement.
The following will report the message @extends is to be used over @augments as it is more evocative of classes than @augments upon encountering @augments.
{
"rules": {},
"settings": {
"jsdoc": {
"tagNamePreference": {
"augments": {
"message": "@extends is to be used over @augments as it is more evocative of classes than @augments",
"replacement": "extends"
}
}
}
}
}
If one wishes to reject a normally valid tag, e.g., @todo, one may set the tag to false:
{
"rules": {},
"settings": {
"jsdoc": {
"tagNamePreference": {
"todo": false
}
}
}
}
A project wishing to ensure no blocks are left excluded from entering the
documentation, might wish to prevent the @ignore tag in the above manner.
Or one may set the targeted tag to an object with a custom message, but without a replacement property:
{
"rules": {},
"settings": {
"jsdoc": {
"tagNamePreference": {
"todo": {
"message": "We expect immediate perfection, so don't leave to-dos in your code."
}
}
}
}
}
Note that the preferred tags indicated in the settings.jsdoc.tagNamePreference
map will be assumed to be defined by check-tag-names.
Default Preferred Aliases
The defaults in eslint-plugin-jsdoc (for tags which offer
aliases) are as follows:
@abstract(over@virtual)@augments(over@extends)@class(over@constructor)@constant(over@const)@default(over@defaultvalue)@description(over@desc)@external(over@host)@file(over@fileoverview,@overview)@fires(over@emits)@function(over@func,@method)@member(over@var)@param(over@arg,@argument)@property(over@prop)@returns(over@return)@throws(over@exception)@yields(over@yield)
This setting is utilized by the the rule for tag name checking
(check-tag-names) as well as in the @param and @require rules:
check-param-namescheck-tag-namesrequire-hyphen-before-param-descriptionrequire-descriptionrequire-paramrequire-param-descriptionrequire-param-namerequire-param-typerequire-returnsrequire-returns-checkrequire-returns-descriptionrequire-returns-type
@override/@augments/@extends/@implements Without Accompanying @param/@description/@example/@returns
The following settings allows the element(s) they reference to be omitted
on the JSDoc comment block of the function or that of its parent class
for any of the "require" rules (i.e., require-param, require-description,
require-example, or require-returns).
settings.jsdoc.overrideReplacesDocs(@override) - Defaults totruesettings.jsdoc.augmentsExtendsReplacesDocs(@augmentsor its alias@extends) - Defaults tofalse.settings.jsdoc.implementsReplacesDocs(@implements) - Defaults tofalse
The format of the configuration is as follows:
{
"rules": {},
"settings": {
"jsdoc": {
"overrideReplacesDocs": true,
"augmentsExtendsReplacesDocs": true,
"implementsReplacesDocs": true
}
}
}
Settings to Configure check-types and no-undefined-types
-
settings.jsdoc.preferredTypesAn option map to indicate preferred or forbidden types (if default types are indicated here, these will have precedence over the default recommendations forcheck-types). The keys of this map are the types to be replaced (or forbidden). These keys may include:- The "ANY" type,
* - The pseudo-type
[]which we use to denote the parent (array) types used in the syntaxstring[],number[], etc. - The pseudo-type
.<>(or.) to represent the formatArray.<value>orObject.<key, value> - The pseudo-type
<>to represent the formatArray<value>orObject<key, value> - A plain string type, e.g.,
MyType - A plain string type followed by one of the above pseudo-types (except
for
[]which is always assumed to be anArray), e.g.,Array., orSpecialObject<>.
If a bare pseudo-type is used, it will match all parent types of that form. If a pseudo-type prefixed with a type name is used, it will only match parent types of that form and type name.
The values can be:
falseto forbid the type- a string to indicate the type that should be preferred in its place
(and which
fixmode can replace); this can be one of the formats of the keys described above.- Note that the format will not be changed unless you use a pseudo-type
in the replacement. (For example,
'Array.<>': 'MyArray'will changeArray.<string>toMyArray.<string>, preserving the dot. To get rid of the dot, you must use the pseudo-type with<>, i.e.,'Array.<>': 'MyArray<>', which will changeArray.<string>toMyArray<string>). - If you use a bare pseudo-type in the replacement (e.g.,
'MyArray.<>': '<>'), the type will be converted to the format of the pseudo-type without changing the type name. For example,MyArray.<string>will becomeMyArray<string>butArray.<string>will not be modified.
- Note that the format will not be changed unless you use a pseudo-type
in the replacement. (For example,
- an object with:
- the key
messageto provide a specific error message when encountering the discouraged type.- The message string will have the substrings with special meaning,
{{tagName}}and{{tagValue}}, replaced with their corresponding value.
- The message string will have the substrings with special meaning,
- an optional key
replacementwith either of the following values:- a string type to be preferred in its place (and which
fixmode can replace) false(for forbidding the type)
- a string type to be preferred in its place (and which
- the key
- The "ANY" type,
Note that the preferred types indicated as targets in settings.jsdoc.preferredTypes
map will be assumed to be defined by no-undefined-types.
See the option of check-types, unifyParentAndChildTypeChecks, for
how the keys of preferredTypes may have <> or .<> (or just .)
appended and its bearing on whether types are checked as parents/children
only (e.g., to match Array if the type is Array vs. Array.<string>).
Rules
check-access
Checks that @access tags use one of the following values:
- "package", "private", "protected", "public"
Also reports:
- Mixing of
@accesswith@public,@private,@protected, or@packageon the same doc block. - Use of multiple instances of
@access(or the@public, etc. style tags) on the same doc block.

check-examples
Ensures that (JavaScript) examples within JSDoc adhere to ESLint rules.
Options
The options below all default to no-op/false except as noted.
captionRequired
JSDoc specs use of an optional <caption> element at the beginning of
@example.
The option captionRequired insists on a <caption> being present at
the beginning of any @example.
exampleCodeRegex and rejectExampleCodeRegex
JSDoc does not specify a formal means for delimiting code blocks within
@example (it uses generic syntax highlighting techniques for its own
syntax highlighting). The following options determine whether a given
@example tag will have the check-examples checks applied to it:
exampleCodeRegex- Regex which whitelists lintable examples. If a parenthetical group is used, the first one will be used, so you may wish to use(?:...)groups where you do not wish the first such group treated as one to include. If no parenthetical group exists or matches, the whole matching expression will be used. An example might be"^```(?:js|javascript)([\\s\\S]*)```\s*$"to only match explicitly fenced JavaScript blocks. Defaults to only using theuflag, so to add your own flags, encapsulate your expression as a string, but like a literal, e.g.,/```js.*```/gi. Note that specifying a global regular expression (i.e., withg) will allow independent linting of matched blocks within a single@example.rejectExampleCodeRegex- Regex blacklist which rejects non-lintable examples (has priority overexampleCodeRegex). An example might be"^`"to avoid linting fenced blocks which may indicate a non-JavaScript language. SeeexampleCodeRegexon how to add flags if the defaultuis not sufficient.
If neither is in use, all examples will be matched. Note also that even if
captionRequired is not set, any initial <caption> will be stripped out
before doing the regex matching.
paddedIndent
This integer property allows one to add a fixed amount of whitespace at the
beginning of the second or later lines of the example to be stripped so as
to avoid linting issues with the decorative whitespace. For example, if set
to a value of 4, the initial whitespace below will not trigger indent
rule errors as the extra 4 spaces on each subsequent line will be stripped
out before evaluation.
/**
* @example
* anArray.filter((a) => {
* return a.b;
* });
*/
reportUnusedDisableDirectives
If not set to false, reportUnusedDisableDirectives will report disabled
directives which are not used (and thus not needed). Defaults to true.
Corresponds to ESLint's --report-unused-disable-directives.
Inline ESLint config within @example JavaScript is allowed, though the
disabling of ESLint directives which are not needed by the resolved rules
will be reported as with the ESLint --report-unused-disable-directives
command.
Options for Determining ESLint Rule Applicability (allowInlineConfig, noDefaultExampleRules, matchingFileName, configFile, checkEslintrc, and baseConfig)
The following options determine which individual ESLint rules will be
applied to the JavaScript found within the @example tags (as determined
to be applicable by the above regex options). They are ordered by
decreasing precedence:
allowInlineConfig- If not set tofalse, will allow inline config within the@exampleto override other config. Defaults totrue.noDefaultExampleRules- Setting totruewill disable the default rules which are expected to be troublesome for most documentation use. See the section below for the specific default rules.configFile- A config file. Corresponds to ESLint's-c.matchingFileName- Option for a file name (even non-existent) to trigger specific rules defined in one's config; usable with ESLint.eslintrc.*overrides->filesglobs, to apply a desired subset of rules with@example(besides allowing for rules specific to examples, this option can be useful for enabling reuse of the same rules within@exampleas with JavaScript Markdown lintable by other plugins, e.g., if one setsmatchingFileNametodummy.mdso that@examplerules will follow one's Markdown rules).checkEslintrc- Defaults totruein adding rules based on an.eslintrc.*file. Setting tofalsecorresponds to ESLint's--no-eslintrc. IfmatchingFileNameis set, this will automatically betrueand will use the config corresponding to that file. IfmatchingFileNameis not set and this value is set tofalse, the.eslintrc.*configs will not be checked. IfmatchingFileNameis not set, and this is unset or set totrue, the.eslintrc.*configs will be checked as though the file name were the same as the file containing the example, with any file extension changed to ".md" (and if there is no file extension, "dummy.md" will be used). This allows convenient sharing of similar rules with often also context-free Markdown as well as use ofoverridesas described undermatchingFileName. Note that this option (whether set bymatchingFileNameor set manually totrue) may come at somewhat of a performance penalty as the file's existence is checked by eslint.baseConfig- Set to an object of rules with the same schema as.eslintrc.*for defaults.
Rules Disabled by Default Unless noDefaultExampleRules is Set to true
eol-last- Insisting that a newline "always" be at the end is less likely to be desired in sample code as with the code file convention.no-console- This rule is unlikely to have inadvertent temporary debugging within examples.no-multiple-empty-lines- This rule may be problematic for projects which use an initial newline just to start an example. Also, projects may wish to use extra lines within examples just for easier illustration purposes.no-undef- Many variables in examples will beundefined.no-unused-vars- It is common to define variables for clarity without always using them within examples.padded-blocks- It can generally look nicer to pad a little even if one's code follows more stringency as far as block padding.import/no-unresolved- One wouldn't generally expect example paths to resolve relative to the current JavaScript file as one would with real code.import/unambiguous- Snippets in examples are likely too short to always include full import/export info.node/no-missing-import- Seeimport/no-unresolved.node/no-missing-require- Seeimport/no-unresolved.

check-indentation
Reports invalid padding inside JSDoc blocks.
Ignores parts enclosed in Markdown "code block"'s. For example, the following description is not reported:
/**
* Some description:
* ```html
* <section>
* <title>test</title>
* </section>
* ```
*/
Options
This rule has an object option.
excludeTags
Array of tags (e.g., ['example', 'description']) whose content will be
"hidden" from the check-indentation rule. Defaults to ['example'].
By default, the whole JSDoc block will be checked for invalid padding.
That would include @example blocks too, which can get in the way
of adding full, readable examples of code without ending up with multiple
linting issues.
When disabled (by passing excludeTags: [] option), the following code will
report a padding issue:
/**
* @example
* anArray.filter((a) => {
* return a.b;
* });

check-param-names
Ensures that parameter names in JSDoc match those in the function declaration.

their presence within the function signature. Other inconsistencies between

Deconstructing Function Parameter
eslint-plugin-jsdoc does not validate names of parameters in function deconstruction, e.g.
/**
* @param foo
*/
function quux ({
a,
b
}) {
}
{a, b} is an ObjectPattern AST type and does not have a name. Therefore, the associated parameter in JSDoc block can have any name.
Likewise for the pattern [a, b] which is an ArrayPattern.
check-property-names
Ensures that property names in JSDoc are not duplicated on the same block and that nested properties have defined roots.

check-types
Reports invalid types.
By default, ensures that the casing of native types is the same as in this list:
undefined
null
boolean
number
bigint
string
symbol
object
Array
Function
Date
RegExp
Options
check-types allows one option:
- An option object:
- with the key
noDefaultsto insist that only the supplied option type map is to be used, and that the default preferences (such as "string" over "String") will not be enforced. The option's default isfalse. - with the key
exemptTagContextswhich will avoid reporting when a bad type is found on a specified tag. Set to an array of objects with a keytagset to the tag to exempt, and atypeskey which can either betrueto indicate that any types on that tag will be allowed, or to an array of strings which will only allow specific bad types. If an array of strings is given, these must match the type exactly, e.g., if you only allow"object", it will not allow"object<string, string>". Note that this is different from the behavior ofsettings.jsdoc.preferredTypes. This option is useful for normally restricting generic types likeobjectwithpreferredTypes, but allowingtypedefto indicate that its base type isobject. - with the key
unifyParentAndChildTypeCheckswhich will treatsettings.jsdoc.preferredTypeskeys such asSomeTypeas matching not only child types such as an unadornedSomeTypebut alsoSomeType<aChildType>,SomeType.<aChildType>, or ifSomeTypeisArray(or[]), it will matchaChildType[]. If this isfalseor unset, the former format will only apply to types which are not parent types/unions whereas the latter formats will only apply for parent types/unions. The special types[],.<>(or.), and<>act only as parent types (and will not match a bare child type such asArrayeven when unified, though, as mentioned,Arraywill match saystring[]orArray.<string>when unified). The special type*is only a child type. Note that there is no detection of parent and child type together, e.g., you cannot specify preferences forstring[]specifically as distinct from saynumber[], but you can target both with[]or the child typesnumberorstring.
- with the key
See also the documentation on settings.jsdoc.preferredTypes which impacts
the behavior of check-types.
Why not capital case everything?
Why are boolean, number and string exempt from starting with a capital letter? Let's take string as an example. In Javascript, everything is an object. The string Object has prototypes for string functions such as .toUpperCase().
Fortunately we don't have to write new String() everywhere in our code. Javascript will automatically wrap string primitives into string Objects when we're applying a string function to a string primitive. This way the memory footprint is a tiny little bit smaller, and the GC has less work to do.
So in a sense, there two types of strings in Javascript; {string} literals, also called primitives and {String} Objects. We use the primitives because it's easier to write and uses less memory. {String} and {string} are technically both valid, but they are not the same.
new String('lard') // String {0: "l", 1: "a", 2: "r", 3: "d", length: 4}
'lard' // "lard"
new String('lard') === 'lard' // false
To make things more confusing, there are also object literals and object Objects. But object literals are still static Objects and object Objects are instantiated Objects. So an object primitive is still an object Object.
However, Object.create(null) objects are not instanceof Object, however, so
in the case of this Object we lower-case to indicate possible support for
these objects.
Basically, for primitives, we want to define the type as a primitive, because that's what we use in 99.9% of cases. For everything else, we use the type rather than the primitive. Otherwise it would all just be {object}.
In short: It's not about consistency, rather about the 99.9% use case. (And some functions might not even support the objects if they are checking for identity.)
| type name | typeof |

check-values
This rule checks the values for a handful of tags:
@version- Checks that there is a present and valid semver version value.@since- As with@version@license- Checks that there is a present and valid SPDX identifier or is present within anallowedLicensesoption.@author- Checks there is a value present, and if the optionallowedAuthorsis present, ensure that the author value is one of these array items.
Options
allowedAuthors
An array of allowable author values. If absent, only non-whitespace will be checked for.
allowedLicenses
An array of allowable license values or true to allow any license text.
If present as an array, will be used in place of SPDX identifiers.
licensePattern
A string to be converted into a RegExp (with u flag) and whose first
parenthetical grouping, if present, will match the portion of the license
description to check (if no grouping is present, then the whole portion
matched will be used). Defaults to ([^\n]*), i.e., the SPDX expression
is expected before any line breaks.

empty-tags
Expects the following tags to be empty of any content:
@abstract@async@generator@global@hideconstructor@ignore@inheritdoc@inner@instance@override@readonly
The following will also be expected to be empty unless settings.jsdoc.mode
is set to "closure" (which allows types).
@package@private@protected@public@static
Note that @private will still be checked for content by this rule even with
settings.jsdoc.ignorePrivate set to true (a setting which normally
causes rules not to take effect).

implements-on-classes
Reports an issue with any non-constructor function using @implements.
Constructor functions, whether marked with @class, @constructs, or being
an ES6 class constructor, will not be flagged.
To indicate that a function follows another function's signature, one might
instead use @type to indicate the @function or @callback to which the
funciton is adhering.
Options
contexts
Set this to an array of strings representing the AST context
where you wish the rule to be applied.
Overrides the default contexts (see below). Set to "any" if you want
the rule to apply to any jsdoc block throughout your files (as is necessary
for finding function blocks not attached to a function declaration or
expression, i.e., @callback or @function (or its aliases @func or
@method) (including those associated with an @interface).

match-description
Enforces a regular expression pattern on descriptions.
The default is this basic expression to match English sentences (Support for Unicode upper case may be added in a future version when it can be handled by our supported Node versions):
^([A-Z]|[`\\d_])[\\s\\S]*[.?!`]$
Applies to the jsdoc block description and @description (or @desc)
by default but the tags option (see below) may be used to match other tags.
Options
matchDescription
You can supply your own expression to override the default, passing a
matchDescription string on the options object.
{
'jsdoc/match-description': ['error', {matchDescription: '[A-Z].*\\.'}]
}
As with the default, the supplied regular expression will be applied with the
Unicode ("u") flag and is not case-insensitive.
tags
If you want different regular expressions to apply to tags, you may use
the tags option object:
{
'jsdoc/match-description': ['error', {tags: {
param: '\\- [A-Z].*\\.',
returns: '[A-Z].*\\.'
}}]
}
In place of a string, you can also add true to indicate that a particular
tag should be linted with the matchDescription value (or the default).
{
'jsdoc/match-description': ['error', {tags: {
param: true,
returns: true
}}]
}
The tags @param/@arg/@argument and @property/@prop will be properly
parsed to ensure that the matched "description" text includes only the text
after the name.
All other tags will treat the text following the tag name, a space, and
an optional curly-bracketed type expression (and another space) as part of
its "description" (e.g., for @returns {someType} some description, the
description is some description while for @some-tag xyz, the description
is xyz).
mainDescription
If you wish to override the main function description without changing the
default match-description, you may use mainDescription:
{
'jsdoc/match-description': ['error', {
mainDescription: '[A-Z].*\\.',
tags: {
param: true,
returns: true
}
}]
}
There is no need to add mainDescription: true, as by default, the main
function (and only the main function) is linted, though you may disable checking
it by setting it to false.
contexts
Set this to an array of strings representing the AST context
where you wish the rule to be applied (e.g., ClassDeclaration for ES6 classes).
Overrides the default contexts (see below). Set to "any" if you want
the rule to apply to any jsdoc block throughout your files.
| Context | ArrowFunctionExpression, FunctionDeclaration, FunctionExpression; others when contexts option enabled |
| Tags | docblock and @description by default but more with tags |
| Aliases | @desc |
| Settings | |
| Options | contexts, tags (accepts tags with names and optional type such as 'param', 'arg', 'argument', 'property', and 'prop', and accepts arbitrary list of other tags with an optional type (but without names), e.g., 'returns', 'return'), mainDescription, matchDescription |

no-types
This rule reports types being used on @param or @returns.
The rule is intended to prevent the indication of types on tags where the type information would be redundant with TypeScript.
Options
contexts
Set this to an array of strings representing the AST context
where you wish the rule to be applied.
Overrides the default contexts (see below). Set to "any" if you want
the rule to apply to any jsdoc block throughout your files (as is necessary
for finding function blocks not attached to a function declaration or
expression, i.e., @callback or @function (or its aliases @func or
@method) (including those associated with an @interface).

no-undefined-types
Checks that types in jsdoc comments are defined. This can be used to check unimported types.
When enabling this rule, types in jsdoc comments will resolve as used
variables, i.e. will not be marked as unused by no-unused-vars.
In addition to considering globals found in code (or in ESLint-indicated
globals) as defined, the following tags will also be checked for
name(path) definitions to also serve as a potential "type" for checking
the tag types in the table below:
@callback, @class (or @constructor), @constant (or @const), @event, @external (or @host), @function (or @func or @method), @interface, @member (or @var), @mixin, @name, @namespace, @template (for "closure" or "typescript" settings.jsdoc.mode only), @typedef.
The following tags will also be checked but only when the mode is closure:
@package, @private, @protected, @public, @static
The following types are always considered defined.
null,undefined,void,string,boolean,object,function,symbolnumber,bigint,NaN,Infinityany,*Array,Object,RegExp,Date,Function
Note that preferred types indicated within settings.jsdoc.preferredTypes will
also be assumed to be defined.
Options
An option object may have the following key:
definedTypes- This array can be populated to indicate other types which are automatically considered as defined (in addition to globals, etc.). Defaults to an empty array.

require-description-complete-sentence
Requires that block description, explicit @description, and @param/@returns
tag descriptions are written in complete sentences, i.e.,
- Description must start with an uppercase alphabetical character.
- Paragraphs must start with an uppercase alphabetical character.
- Sentences must end with a period.
- Every line in a paragraph (except the first) which starts with an uppercase character must be preceded by a line ending with a period.
- A colon or semi-colon followed by two line breaks is still part of the containing paragraph (unlike normal dual line breaks).
- Text within inline tags
{...}are not checked for sentence divisions. - Periods after items within the
abbreviationsoption array are not treated as sentence endings.
Options
tags
If you want additional tags to be checked for their descriptions, you may add them within this option.
{
'jsdoc/require-description-complete-sentence': ['error', {tags: ['see', 'copyright']}]
}
The tags @param/@arg/@argument and @property/@prop will be properly
parsed to ensure that the checked "description" text includes only the text
after the name.
All other tags will treat the text following the tag name, a space, and
an optional curly-bracketed type expression (and another space) as part of
its "description" (e.g., for @returns {someType} some description, the
description is some description while for @some-tag xyz, the description
is xyz).
abbreviations
You can provide an abbreviations options array to avoid such strings of text
being treated as sentence endings when followed by dots. The . is not
necessary at the end of the array items.

require-description
Requires that all functions have a description.
- All functions must have an implicit description or have the option
descriptionStyleset totag. - Every jsdoc block description (or description tag if
descriptionStyleis"tag") must have a non-empty description that explains the purpose of the method.
Options
An options object may have any of the following properties:
contexts- Set to an array of strings representing the AST context where you wish the rule to be applied (e.g.,ClassDeclarationfor ES6 classes). Overrides the default contexts (see below). Set to"any"if you want the rule to apply to any jsdoc block throughout your files.exemptedBy- Array of tags (e.g.,['type']) whose presence on the document block avoids the need for a@description. Defaults to an empty array.descriptionStyle- Whether to accept implicit descriptions ("body") or@descriptiontags ("tag") as satisfying the rule. Set to"any"to accept either style. Defaults to"body".

require-example
Requires that all functions have examples.
- All functions must have one or more
@exampletags. - Every example tag must have a non-empty description that explains the method's usage.
Options
This rule has an object option.
exemptedBy
Array of tags (e.g., ['type']) whose presence on the document
block avoids the need for an @example. Defaults to an empty array.
avoidExampleOnConstructors
Set to true to avoid the need for an example on a constructor (whether
indicated as such by a jsdoc tag or by being within an ES6 class).
Defaults to false.
contexts
Set this to an array of strings representing the AST context
where you wish the rule to be applied (e.g., ClassDeclaration for ES6 classes).
Overrides the default contexts (see below). Set to "any" if you want
the rule to apply to any jsdoc block throughout your files.
Fixer
The fixer for require-example will add an empty @example, but it will still
report a missing example description after this is added.

require-file-overview
Checks that:
- All files have a
@file,@fileoverview, or@overviewtag. - Duplicate file overview tags within a given file will be reported
- File overview tags will be reported which are not, as per the docs, "at the beginning of the file"–where beginning of the file is interpreted in this rule as being when the overview tag is not preceded by anything other than a comment.
Options
tags
The keys of this object are tag names, and the values are configuration objects indicating what will be checked for these whole-file tags.
Each configuration object has the following boolean keys (which default
to false when this option is supplied): mustExist, preventDuplicates,
initialCommentsOnly. These correspond to the three items above.
When no tags is present, the default is:
{
"file": {
"initialCommentsOnly": true,
"mustExist": true,
"preventDuplicates": true,
}
}
You can add additional tag names and/or override file if you supply this
option, e.g., in place of or in addition to file, giving other potential
file global tags like @license, @copyright, @author, @module or
@exports, optionally restricting them to a single use or preventing them
from being preceded by anything besides comments.
For example:
{
"license": {
"mustExist": true,
"preventDuplicates": true,
}
}
This would require one and only one @license in the file, though because
initialCommentsOnly is absent and defaults to false, the @license
can be anywhere.
In the case of @license, you can use this rule along with the
check-values rule (with its allowedLicenses or licensePattern options),
to enforce a license whitelist be present on every JS file.
Note that if you choose to use preventDuplicates with license, you still
have a way to allow multiple licenses for the whole page by using the SPDX
"AND" expression, e.g., @license (MIT AND GPL-3.0).
Note that the tag names are the main jsdoc tag name, so you should use file
in this configuration object regardless of whether you have configured
fileoverview instead of file on tagNamePreference (i.e., fileoverview
will be checked, but you must use file on the configuration object).

require-hyphen-before-param-description
Requires a hyphen before the @param description.
Options
This rule takes one optional string argument and an optional options object.
If the string is "always" then a problem is raised when there is no hyphen
before the description. If it is "never" then a problem is raised when there
is a hyphen before the description. The default value is "always".
The options object may have the following properties:
checkProperties- Boolean on whether to also apply the rule to@propertytags.

require-jsdoc
Checks for presence of jsdoc comments, on class declarations as well as functions.
Options
Accepts one optional options object with the following optional keys.
-
publicOnly- This option will insist that missing jsdoc blocks are only reported for function bodies / class declarations that are exported from the module. May be a boolean or object. If set totrue, the defaults below will be used. If unset, jsdoc block reporting will not be limited to exports.This object supports the following optional boolean keys (
falseunless otherwise noted):ancestorsOnly- Only check node ancestors to check if node is exportedesm- ESM exports are checked for JSDoc comments (Defaults totrue)cjs- CommonJS exports are checked for JSDoc comments (Defaults totrue)window- Window global exports are checked for JSDoc comments
-
require- An object with the following optional boolean keys which all default tofalseexcept as noted, indicating the contexts where the rule will apply:ArrowFunctionExpressionClassDeclarationClassExpressionFunctionDeclaration(defaults totrue)FunctionExpressionMethodDefinition
-
contexts- Set this to an array of strings representing the additional AST contexts where you wish the rule to be applied (e.g.,Propertyfor properties). Defaults to an empty array. -
exemptEmptyFunctions(default: false) - Whentrue, the rule will not report missing jsdoc blocks above functions/methods with no parameters or return values (intended where variable names are sufficient for themselves as documentation).

require-returns
Requires returns are documented.
Will also report if multiple @returns tags are present.
Options
exemptedBy- Array of tags (e.g.,['type']) whose presence on the document block avoids the need for a@returns. Defaults to an empty array.forceRequireReturn- Set totrueto always insist on@returnsdocumentation regardless of implicit or explicitreturn's in the function. May be desired to flag that a project is aware of anundefined/voidreturn. Defaults tofalse.forceReturnsWithAsync- By defaultasyncfunctions that do not explicitly return a value pass this rule as anasyncfunction will always return aPromise, even if thePromiseresolves to void. You can force allasyncfunctions to require return statements by settingforceReturnsWithAsynctotrueon the options object. This may be useful for flagging that there has been consideration of return type. Defaults tofalse.contexts- Set this to an array of strings representing the AST context where you wish the rule to be applied. Overrides the default contexts (see below). Set to"any"if you want the rule to apply to any jsdoc block throughout your files (as is necessary for finding function blocks not attached to a function declaration or expression, i.e.,@callbackor@function(or its aliases@funcor@method) (including those associated with an@interface). This rule will only apply on non-default contexts when there is such a tag present and theforceRequireReturnoption is set or if theforceReturnsWithAsyncoption is set with a present@asynctag (since we are not checking against the actualreturnvalues in these cases).

valid-types
Requires all types to be valid JSDoc or Closure compiler types without syntax errors.
Also impacts behaviors on namepath (or event)-defining and pointing tags:
- Name(path)-defining tags requiring namepath:
@external,@host,@name,@typedef - Name(path)-defining tags (which may have value without namepath or their
namepath can be expressed elsewhere on the block):
@event,@callback,@class,@constructor,@constant,@const,@function,@func,@method,@interface,@member,@var,@mixin,@namespace - Name(path)-pointing tags requiring namepath:
@alias,@augments,@extends,@lends,@memberof,@memberof!,@mixes,@this - Name(path)-pointing tags (which may have value without namepath or their
namepath can be expressed elsewhere on the block):
@listens,@fires,@emits, and@modifies - Name(path)-pointing tags (multiple names in one):
@borrows
...with the following applying to the above sets:
- Expect tags in set 1-4 to have a valid namepath if present
- Prevent sets 2 and 4 from being empty by setting
allowEmptyNamepathstofalseas these tags might have some indicative value without a path or may allow a name expressed elsewhere on the block (but sets 1 and 3 will always fail if empty) - For the special case of set 5, i.e.,
@borrows <that namepath> as <this namepath>, check that both namepaths are present and valid and ensure there is anasbetween them. In the case of<this namepath>, it can be preceded by one of the name path operators,#,., or~. - For the special case of
@memberofand@memberof!(part of set 3), as per the specification, they also allow#,., or~at the end (which is not allowed at the end of normal paths).
Options
allowEmptyNamepaths(default: true) - Set tofalseto disallow empty name paths with@callback,@event,@class,@constructor,@constant,@const,@function,@func,@method,@interface,@member,@var,@mixin,@namespace,@listens,@fires,@modifies, or@emits(these might often be expected to have an accompanying name path, though they have some indicative value without one; these may also allow names to be defined in another manner elsewhere in the block)checkSeesForNamepaths(default: false) - Set this totrueto insist that@seeonly use name paths (the tag is normally permitted to allow other text)
