|
> base is the foundation for creating modular, unit testable and highly pluggable node.js applications, starting with a handful of common methods, like `set`, `get`, `del` and `use`.
|
||
|
|
|
||
|
|
## Install
|
||
|
|
|
||
|
|
Install with [npm](https://www.npmjs.com/):
|
||
|
|
|
||
|
|
```sh
|
||
|
|
$ npm install --save base
|
||
|
|
```
|
||
|
|
|
||
|
|
## What is Base?
|
||
|
|
|
||
|
|
Base is a framework for rapidly creating high quality node.js applications, using plugins like building blocks.
|
||
|
|
|
||
|
|
### Guiding principles
|
||
|
|
|
||
|
|
The core team follows these principles to help guide API decisions:
|
||
|
|
|
||
|
|
* **Compact API surface**: The smaller the API surface, the easier the library will be to learn and use.
|
||
|
|
* **Easy to extend**: Implementors can use any npm package, and write plugins in pure JavaScript. If you're building complex apps, Base simplifies inheritance.
|
||
|
|
* **Easy to test**: No special setup should be required to unit test `Base` or base plugins
|
||
|
|
|
||
|
|
### Minimal API surface
|
||
|
|
|
||
|
|
[The API](#api) was designed to provide only the minimum necessary functionality for creating a useful application, with or without [plugins](#plugins).
|
||
|
|
|
||
|
|
**Base core**
|
||
|
|
|
||
|
|
Base itself ships with only a handful of [useful methods](#api), such as:
|
||
|
|
|
||
|
|
* `.set`: for setting values on the instance
|
||
|
|
* `.get`: for getting values from the instance
|
||
|
|
* `.has`: to check if a property exists on the instance
|
||
|
|
* `.define`: for setting non-enumerable values on the instance
|
||
|
|
* `.use`: for adding plugins
|
||
|
|
|
||
|
|
**Be generic**
|
||
|
|
|
||
|
|
When deciding on method to add or remove, we try to answer these questions:
|
||
|
|
|
||
|
|
1. Will all or most Base applications need this method?
|
||
|
|
2. Will this method encourage practices or enforce conventions that are beneficial to implementors?
|
||
|
|
3. Can or should this be done in a plugin instead?
|
||
|
|
|
||
|
|
### Composability
|
||
|
|
|
||
|
|
**Plugin system**
|
||
|
|
|
||
|
|
It couldn't be easier to extend Base with any features or custom functionality you can think of.
|
||
|
|
|
||
|
|
Base plugins are just functions that take an instance of `Base`:
|
||
|
|
|
||
|
|
```js
|
||
|
|
var base = new Base();
|
||
|
|
|
||
|
|
function plugin(base) {
|
||
|
|
// do plugin stuff, in pure JavaScript
|
||
|
|
}
|
||
|
|
// use the plugin
|
||
|
|
base.use(plugin);
|
||
|
|
```
|
||
|
|
|
||
|
|
**Inheritance**
|
||
|
|
|
||
|
|
Easily inherit Base using `.extend`:
|
||
|
|
|
||
|
|
```js
|
||
|
|
var Base = require('base');
|
||
|
|
|
||
|
|
function MyApp() {
|
||
|
|
Base.call(this);
|
||
|
|
}
|
||
|
|
Base.extend(MyApp);
|
||
|
|
|
||
|
|
var app = new MyApp();
|
||
|
|
app.set('a', 'b');
|
||
|
|
app.get('a');
|
||
|
|
//=> 'b';
|
||
|
|
```
|
||
|
|
|
||
|
|
**Inherit or instantiate with a namespace**
|
||
|
|
|
||
|
|
By default, the `.get`, `.set` and `.has` methods set and get values from the root of the `base` instance. You can customize this using the `.namespace` method exposed on the exported function. For example:
|
||
|
|
|
||
|
|
```js
|
||
|
|
var Base = require('base');
|
||
|
|
// get and set values on the `base.cache` object
|
||
|
|
var base = Base.namespace('cache');
|
||
|
|
|
||
|
|
var app = base();
|
||
|
|
app.set('foo', 'bar');
|
||
|
|
console.log(app.cache.foo);
|
||
|
|
//=> 'bar'
|
||
|
|
```
|
||
|
|
|
||
|
|
## API
|
||
|
|
|
||
|
|
**Usage**
|
||
|
|
|
||
|
|
```js
|
||
|
|
var Base = require('base');
|
||
|
|
var app = new Base();
|
||
|
|
app.set('foo', 'bar');
|
||
|
|
console.log(app.foo);
|
||
|
|
//=> 'bar'
|
||
|
|
```
|
||
|
|
|
||
|
|
### [Base](index.js#L44)

|
|
|
||
|
|
**Params**
|
||
|
|
|
||
|
|
* `config` **{Object}**: If supplied, this object is passed to [cache-base](https://github.com/jonschlinkert/cache-base) to merge onto the the instance upon instantiation.

|
|
### [.isRegistered](index.js#L145)
|
||
|
|
|
||
|
|
Returns true if a plugin has already been registered on an instance.
|
||
|
|
|
||
|
|
Plugin implementors are encouraged to use this first thing in a plugin
|
||
|
|
to prevent the plugin from being called more than once on the same
|
||
|
|
instance.
|
||
|
|
|
||
|
|
**Params**
|
||
|
|
|
||
|
|
* `name` **{String}**: The plugin name.
|
||
|
|
* `register` **{Boolean}**: If the plugin if not already registered, to record it as being registered pass `true` as the second argument.
|
||
|
|
* `returns` **{Boolean}**: Returns true if a plugin is already registered.
|
||
|
|
|
||
|
|
**Events**
|
||
|
|
|
||
|
|
* `emits`: `plugin` Emits the name of the plugin being registered. Useful for unit tests, to ensure plugins are only registered once.
|
||
|
|
|
||
|
|
**Example**
|
||
|
|
|
||
|
|
```js
|
||
|
|
var base = new Base();
|
||
|
|
base.use(function(app) {
|
||
|
|
if (app.isRegistered('myPlugin')) return;
|
||
|
|
// do stuff to `app`
|
||
|
|
});
|
||
|
|
|
||
|
|
// to also record the plugin as being registered
|
||
|
|
base.use(function(app) {
|
||
|
|
if (app.isRegistered('myPlugin', true)) return;
|
||
|
|
// do stuff to `app`
|
||
|
|
});
|
||
|
|
```
|
||
|
|
|
||
|
|
### [.use](index.js#L175)
|
||
|
|
|
||
|
|
Define a plugin function to be called immediately upon init. Plugins are chainable and expose the following arguments to the plugin function:
|
||
|
|
|
||
|
|
* `app`: the current instance of `Base`
|
||
|
|
* `base`: the [first ancestor instance](#base) of `Base`
|
||
|
|
|
||
|
|
**Params**
|
||
|
|
|
||
|
|
* `fn` **{Function}**: plugin function to call
|
||
|
|
* `returns` **{Object}**: Returns the item instance for chaining.
|
||
|
|
|
||
|
|
**Example**
|
||
|
|
|
||
|
|
```js
|
||
|
|
var app = new Base()
|
||
|
|
.use(foo)
|
||
|
|
.use(bar)
|
||
|
|
.use(baz)
|
||
|
|
```
|
||
|
|
|
||
|
|
### [.define](index.js#L197)
|
||
|
|
|
||
|
|
The `.define` method is used for adding non-enumerable property on the instance. Dot-notation is **not supported** with `define`.
|
||
|
|
|
||
|
|
**Params**
|
||
|
|
|
||
|
|
* `key` **{String}**: The name of the property to define.
|
||
|
|
* `value` **{any}**
|
||
|
|
* `returns` **{Object}**: Returns the instance for chaining.
|
||
|
|
|
||
|
|
**Example**
|
||
|
|
|
||
|
|
```js
|
||
|
|
// arbitrary `render` function using lodash `template`
|
||
|
|
app.define('render', function(str, locals) {
|
||
|
|
return _.template(str)(locals);
|
||
|
|
});
|
||
|
|
```
|
||
|
|
|
||
|
|
### [.mixin](index.js#L222)
|
||
|
|
|
||
|
|
Mix property `key` onto the Base prototype. If base is inherited using `Base.extend` this method will be overridden by a new `mixin` method that will only add properties to the prototype of the inheriting application.
|
||
|
|
|
||
|
|
**Params**
|
||
|
|
|
||
|
|
* `key` **{String}**
|
||
|
|
* `val` **{Object|Array}**
|
||
|
|
* `returns` **{Object}**: Returns the `base` instance for chaining.
|
||
|
|
|
||
|
|
**Example**
|
||
|
|
|
||

app.mixin('foo', function() {
|
||
|
|
// do stuff
|
||
|
|
});
|
||
|
|
```
|
||
|
|
|
||
|
|
### [.base](index.js#L268)
|
||
|
|
|
||
|
|
Getter/setter used when creating nested instances of `Base`, for storing a reference to the first ancestor instance. This works by setting an instance of `Base` on the `parent` property of a "child" instance. The `base` property defaults to the current instance if no `parent` property is defined.
|
||
|
|
|
||
|
|
**Example**
|
||
|
|
|
||
|
|
```js
|
||
|
|
// create an instance of `Base`, this is our first ("base") instance
|
||
|
|
var first = new Base();
|
||
|
|
first.foo = 'bar'; // arbitrary property, to make it easier to see what's happening later
|
||
|
|
|
||
|
|
// create another instance
|
||
|
|
var second = new Base();
|
||
|
|
// create a reference to the first instance (`first`)
|
||
|
|
second.parent = first;
|
||
|
|
|
||
|
|
// create another instance
|
||
|
|
var third = new Base();
|
||
|
|
// create a reference to the previous instance (`second`)
|
||
|
|
// repeat this pattern every time a "child" instance is created
|
||
|
|
third.parent = second;
|
||
|
|
|
||
|
|
// we can always access the first instance using the `base` property
|
||
|
|
console.log(first.base.foo);
|
||
|
|
//=> 'bar'
|
||
|
|
console.log(second.base.foo);
|
||
|
|
//=> 'bar'
|
||
|
|
console.log(third.base.foo);
|
||
|
|
//=> 'bar'
|
||
|
|
// and now you know how to get to third base ;)
|
||
|
|
```
|
||
|
|
|
||
|
|
### [#use](index.js#L293)
|
||
|
|
|
||
|
|
Static method for adding global plugin functions that will be added to an instance when created.

|
||
|
|
|
||
|
|
**Example**
|
||
|
|
|
||
|
|
```js
|
||
|
|
Base.use(function(app) {
|
||
|
|
app.foo = 'bar';
|
||
|
|
});
|
||
|
|
var app = new Base();
|
||
|
|
console.log(app.foo);
|
||
|
|
//=> 'bar'
|
||
|
|
```
|
||
|
|
|
||
|
|
### [#extend](index.js#L337)
|
||
|
|
|
||
|
|
Static method for inheriting the prototype and static methods of the `Base` class. This method greatly simplifies the process of creating inheritance-based applications. See [static-extend](https://github.com/jonschlinkert/static-extend) for more details.
|
||
|
|
|
||
|
|
**Params**
|
||
|
|
|
||
|
|
* `Ctor` **{Function}**: constructor to extend
|
||
|
|
* `methods` **{Object}**: Optional prototype properties to mix in.
|
||
|
|
* `returns` **{Object}**: Returns the `Base` constructor for chaining
|
||
|
|
|
||
|
|
**Example**
|
||
|
|
|
||
|
|
```js
|
||
|
|
var extend = cu.extend(Parent);
|
||
|
|
Parent.extend(Child);
|
||
|
|
|
||
|
|
// optional methods
|
||
|
|
Parent.extend(Child, {
|
||
|
|
foo: function() {},
|
||
|
|
bar: function() {}
|
||
|
|
});
|
||
|
|
```
|
||
|
|
|
||
|
|
### [#mixin](index.js#L379)
|
||
|
|
|
||
|
|
Used for adding methods to the `Base` prototype, and/or to the prototype of child instances. When a mixin function returns a function, the returned function is pushed onto the `.mixins` array, making it available to be used on inheriting classes whenever `Base.mixins()` is called (e.g. `Base.mixins(Child)`).
|
||
|
|
|
||
|
|
**Params**
|
||

proto.foo = function(msg) {
|
||
|
|
return 'foo ' + msg;
|
||
|
|
};
|
||
|
|
});
|
||
|
|
```
|
||
|
|
|
||
|
|
### [#mixins](index.js#L401)
|
||
|
|
|
||
|
|
Static method for running global mixin functions against a child constructor. Mixins must be registered before calling this method.

|
|
||
|
|
* `Child` **{Function}**: Constructor function of a child class

|
|
### [#inherit](index.js#L420)

|
||
|
|
|
||
|
|
```js
|
||
|

|
|
```
|
||
|
|
|
||
|
|
## In the wild
|
||
