var base = new Base();

function plugin(base) {
  // do plugin stuff, in pure JavaScript
}
// use the plugin
base.use(plugin);

var Base = require('base');

function MyApp() {
  Base.call(this);
}
Base.extend(MyApp);

var app = new MyApp();
app.set('a', 'b');
app.get('a');
//=> 'b';

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'

NPM

Install with npm:

$ npm install --save base

yarn

Install with yarn:

$ yarn add base && yarn upgrade

var Base = require('base');
var app = new Base();

// set a value
app.set('foo', 'bar');
console.log(app.foo);
//=> 'bar'

// register a plugin
app.use(function() {
  // do stuff (see API docs for ".use")
});

Create an instance of Base with the given cache and options. Learn about the cache object.

Params

• cache {Object}: If supplied, this object is passed to cache-base to merge onto the the instance.
• options {Object}: If supplied, this object is used to initialize the base.options object.

Example

// initialize with `cache` and `options`
const app = new Base({isApp: true}, {abc: true});
app.set('foo', 'bar');

// values defined with the given `cache` object will be on the root of the instance
console.log(app.baz); //=> undefined
console.log(app.foo); //=> 'bar'
// or use `.get`
console.log(app.get('isApp')); //=> true
console.log(app.get('foo')); //=> 'bar'

// values defined with the given `options` object will be on `app.options
console.log(app.options.abc); //=> true

Set the given name on app._name and app.is* properties. Used for doing lookups in plugins.

Params

• name {String}
• returns {Boolean}

Example

app.is('collection');
console.log(app.type);
//=> 'collection'
console.log(app.isCollection);
//=> true

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

const 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`
});

Call a plugin function or array of plugin functions on the instance. Plugins are called with an instance of base, and options (if defined).

Params

• name {String|Function|Array}: (optional) plugin name
• plugin {Function|Array}: plugin function, or array of functions, to call.
• {...rest}: Any additional arguments to pass to plugins(s).
• returns {Object}: Returns the item instance for chaining.

Example

const app = new Base()
  .use([foo, bar])
  .use(baz)

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

// example of a custom arbitrary `render` function created with lodash's `template` method
app.define('render', (str, locals) => _.template(str)(locals));

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

// create an instance of `Base`, this is our first ("base") instance
const first = new Base();
first.foo = 'bar'; // arbitrary property, to make it easier to see what's happening later

// create another instance
const second = new Base();
// create a reference to the first instance (`first`)
second.parent = first;

// create another instance
const 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'

Static method for adding global plugin functions that will be added to an instance when created.

Params

• fn {Function}: Plugin function to use on each instance.
• returns {Object}: Returns the Base constructor for chaining

Example

Base.use(function(app) {
  app.foo = 'bar';
});
const app = new Base();
console.log(app.foo);
//=> 'bar'

Cache

User-defined properties go on the cache object. This keeps the root of the instance clean, so that only reserved methods and properties on the root.

Base { cache: {} }

You can pass a custom object to use as the cache as the first argument to the Base class when instantiating.

const myObject = {};
const Base = require('base');
const base = new Base(myObject);

Base is part of the Toolkit suite of applications.

Toolkit is a collection of node.js libraries, applications and frameworks for helping developers quickly create high quality node.js applications, web projects, and command-line experiences. There are many other libraries on NPM for handling specific tasks, Toolkit provides the systems and building blocks for creating higher level workflows and processes around those libraries.

Toolkit can be used to create a static site generator, blog framework, documentaton system, command line, task or plugin runner, and more!

Building Blocks

The following libraries can be used as "building blocks" for creating modular applications.

• base: (you are here!) framework for rapidly creating high quality node.js applications, using plugins like building blocks. Base serves as the foundation for several other applications in the Toolkit suite.
• templates: Render templates with any node.js template engine, create and manage template collections. Use helpers, layouts, partials, includes...
• enquirer: Plugin-based prompt system for creating highly customizable command line experiences.
• composer: Plugin-based, async task runner.

Lifecycle Applications

The following applications provide workflows and automation for common phases of the software development lifecycle. Each of these tools can be used entirely standalone or bundled together.

• generate: create projects
• assemble: build projects
• verb: document projects
• update: maintain projects

• base-task: Base plugin that provides a very thin wrapper around https://github.com/doowb/composer for adding task methods to… more | homepage

Running and reviewing unit tests is a great way to get familiarized with a library and its API. You can install dependencies and run tests with the following command:

$ npm install && npm test

Pull requests and stars are always welcome. For bugs and feature requests, please create an issue.

If Base doesn't do what you need, please let us know.
