Basic object cache with get, set, del, and has methods for node.js/javascript projects.

Install

Install with npm:

$ npm install --save cache-base

Usage

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

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.

var Cache = require('cache-base').namespace('data');
var app = new Cache();
app.set('a', 'b');
console.log(app.data);
//=> {a: 'b'}

API

namespace

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

var Cache = require('cache-base').namespace('data');
var cache = new Cache();

cache.set('foo', 'bar');
//=> {data: {foo: 'bar'}}

Cache

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

var app = new Cache();

.set

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

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

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

app.union('a.b', ['foo']);
app.union('a.b', ['bar']);
console.log(app.get('a'));
//=> {b: ['foo', 'bar']}

.get

Return the value of key. Dot notation may be used to get nested property values.

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

app.set('a.b.c', 'd');
app.get('a.b');
//=> {c: 'd'}

app.get(['a', 'b']);
//=> {c: 'd'}

.has

Return true if app has a stored value for key, false only if value is undefined.

Params

  • key {String}
  • returns {Boolean}

Events

  • emits: has with key and true or false as arguments.

Example

app.set('foo', 'bar');
app.has('foo');
//=> true

.del

Delete one or more properties from the instance.

Params

  • key {String|Array}: Property name or array of property names.
  • returns {Object}: Returns the instance for chaining.

Events

  • emits: del with the key as the only argument.

Example

app.del(); // delete all
// or
app.del('foo');
// or
app.del(['foo', 'bar']);

.clear

Reset the entire cache to an empty object.

Example

app.clear();

.visit

Visit method over the properties in the given object, or map visit over the object-elements in an array.

Params

  • method {String}: The name of the base method to call.
  • val {Object|Array}: The object or array to iterate over.
  • returns {Object}: Returns the instance for chaining.

> 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**

});

app.set(key, value);

// also takes an object or array
app.set({name: 'Halle'});

**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).

//=> {c: 'd'}

app.get(['a', 'b']);
//=> {c: 'd'}
```

### [.has](index.js#L171)

* `returns` **{Boolean}**

**Events**

* `emits`: `has` with `key` and true or false as arguments.

**Example**

```js
app.set('foo', 'bar');
app.has('foo');
//=> true

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

### [.clear](index.js#L218)

Reset the entire cache to an empty object.
