> Basic object cache with `get`, `set`, `del`, and `has` methods for node.js/javascript projects.
|
|
|
|
## Install
|
|
|
|
Install with [npm](https://www.npmjs.com/):
|
|
|
|
```sh
|
|
$ npm install --save cache-base
|
|
```
|
|
|
|
## Usage
|
|
|
|
```js
|
|
var Cache = require('cache-base');
|
|
|
|
// instantiate
|
|
var app = new Cache();
|
|
|
|
// set values
|
|
app.set('a', 'b');
|
|
app.set('c.d', 'e');
|
|
|
|
// get values
|
|
app.get('a');
|
|
//=> 'b'
|
|
app.get('c');
|
|
//=> {d: 'e'}
|
|
|
|
console.log(app.cache);
|
|
//=> {a: 'b'}
|
|
```
|
|
|
|
**Inherit**
|
|
|
|
```js
|
|
var util = require('util');
|
|
var Cache = require('cache-base');
|
|
|
|
function MyApp() {
|
|
Cache.call(this);
|
|
}
|
|
util.inherits(MyApp, Cache);
|
|
|
|
var app = new MyApp();
|
|
app.set('a', 'b');
|
|
app.get('a');
|
|
//=> 'b'
|
|
```
|
|
|
|
**Namespace**
|
|
|
|
Define a custom property for storing values.
|
|
|
|
```js
|
|
var Cache = require('cache-base').namespace('data');
|
|
var app = new Cache();
|
|
app.set('a', 'b');
|
|
console.log(app.data);
|
|
//=> {a: 'b'}
|
|
```
|
|
|
|
## API
|
|
|
|
### [namespace](index.js#L29)
|
|
|
|
Create a `Cache` constructor that when instantiated will store values on the given `prop`.
|
|
|
|
**Params**
|
|
|
|
* `prop` **{String}**: The property name to use for storing values.
|
|
* `returns` **{Function}**: Returns a custom `Cache` constructor
|
|
|
|
**Example**
|
|
|
|
```js
|
|
var Cache = require('cache-base').namespace('data');
|
|
var cache = new Cache();
|
|
|
|
cache.set('foo', 'bar');
|
|
//=> {data: {foo: 'bar'}}
|
|
```
|
|
|
|
### [Cache](index.js#L43)
|
|
|
|
Create a new `Cache`. Internally the `Cache` constructor is created using the `namespace` function, with `cache` defined as the storage object.
|
|
|
|
**Params**
|
|
|
|
* `cache` **{Object}**: Optionally pass an object to initialize with.
|
|
|
|
**Example**
|
|
|
|
```js
|
|
var app = new Cache();
|
|
```
|
|
|
|
### [.set](index.js#L84)
|
|
|
|
Assign `value` to `key`. Also emits `set` with the key and value.
|
|
|
|
**Params**
|
|
|
|
* `key` **{String}**
|
|
* `value` **{any}**
|
|
* `returns` **{Object}**: Returns the instance for chaining.
|
|
|
|
**Events**
|
|
|
|
* `emits`: `set` with `key` and `value` as arguments.
|
|
|
|
**Example**
|
|
|
|
```js
|
|
app.on('set', function(key, val) {
|
|
// do something when `set` is emitted
|
|
});
|
|
|
|
app.set(key, value);
|
|
|
|
// also takes an object or array
|
|
app.set({name: 'Halle'});
|
|
app.set([{foo: 'bar'}, {baz: 'quux'}]);
|
|
console.log(app);
|
|
//=> {name: 'Halle', foo: 'bar', baz: 'quux'}
|
|
```
|
|
|
|
### [.union](index.js#L114)
|
|
|
|
Union `array` to `key`. Also emits `set` with the key and value.
|
|
|
|
**Params**
|
|
|
|
* `key` **{String}**
|
|
* `value` **{any}**
|
|
* `returns` **{Object}**: Returns the instance for chaining.
|
|
|
|
**Example**
|
|
|
|
```js
|
|
app.union('a.b', ['foo']);
|
|
app.union('a.b', ['bar']);
|
|
console.log(app.get('a'));
|
|
//=> {b: ['foo', 'bar']}
|
|
```
|
|
|
|
### [.get](index.js#L144)
|
|
|
|
Return the value of `key`. Dot notation may be used to get [nested property values](https://github.com/jonschlinkert/get-value).
|
|
|
|
**Params**
|
|
|
|
* `key` **{String}**: The name of the property to get. Dot-notation may be used.
|
|
* `returns` **{any}**: Returns the value of `key`
|
|
|
|
**Events**
|
|
|
|
* `emits`: `get` with `key` and `value` as arguments.
|
|
|
|
**Example**
|
|
|
|
```js
|
|
app.set('a.b.c', 'd');
|
|
app.get('a.b');
|
|
//=> {c: 'd'}
|
|
|
|
app.get(['a', 'b']);
|
|
//=> {c: 'd'}
|
|
```
|
|
|
|
### [.has](index.js#L171)
|
|

|
|
* `returns` **{Boolean}**

|
|
* `emits`: `has` with `key` and true or false as arguments.
|
|
|
|
**Example**
|
|
|
|
```js
|
|
app.set('foo', 'bar');
|
|
app.has('foo');
|
|
//=> true
|
|
```
|
|
|
|
### [.del](index.js#L199)
|
|
|
|
Delete one or more properties from the instance.
|
|
|

**Params**
|
|
|

|
|
* `returns` **{Object}**: Returns the instance for chaining.
|
|
|
|
**Events**
|
|
|
|
* `emits`: `del` with the `key` as the only argument.
|
|
|
|
**Example**
|
|

|
```js
|
|
app.del(); // delete all
|
|
// or
|
|
app.del('foo');
|
|
// or

|
app.del(['foo', 'bar']);
|
|
```
|

|
|
### [.clear](index.js#L218)
|
|
|
|
Reset the entire cache to an empty object.

|
|
visit over the object-elements in an array.
|
|
|
