# import/max-dependencies
|
||
|
|
|
||
|
|
Forbid modules to have too many dependencies (`import` or `require` statements).
|
||
|
|
|
||
|
|
This is a useful rule because a module with too many dependencies is a code smell, and usually indicates the module is doing too much and/or should be broken up into smaller modules.
|
||
|
|
|
||
|
|
Importing multiple named exports from a single module will only count once (e.g. `import {x, y, z} from './foo'` will only count as a single dependency).
|
||
|
|
|
||
|
|
### Options
|
||
|
|
|
||
|
|
This rule takes the following option:
|
||
|
|
|
||
|
|
`max`: The maximum number of dependencies allowed. Anything over will trigger the rule. **Default is 10** if the rule is enabled and no `max` is specified.
|
||
|
|
|
||
|
|
You can set the option like this:
|
||
|
|
|
||
|
|
```js
|
||
|
|
"import/max-dependencies": ["error", {"max": 10}]
|
||
|
|
```
|
||
|
|
|
||
|
|
|
||
|
|
## Example
|
||
|
|
|
||
|
|
Given a max value of `{"max": 2}`:
|
||
|
|
|
||
|
|
### Fail
|
||
|
|
|
||
|
|
```js
|
||
|
|
import a from './a'; // 1
|
||
|
|
const b = require('./b'); // 2
|
||
|
|
import c from './c'; // 3 - exceeds max!
|
||
|
|
```
|
||
|
|
|
||
|
|
### Pass
|
||
|
|
|
||
|
|
```js
|
||
|
|
import a from './a'; // 1
|
||
|
|
const anotherA = require('./a'); // still 1
|
||
|
|
import {x, y, z} from './foo'; // 2
|
||
|
|
```
|
||
|
|
|
||
|
|
## When Not To Use It
|
||
|
|
|
||
|
|
If you don't care how many dependencies a module has.
