base

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');

//=> 'bar'

Install

NPM

Install

Install with npm:

$ npm install --save base

yarn

Install with yarn:

$ yarn add base && yarn upgrade

Usage

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")
});

API

Base

Create an instance of Base with the given config and options.

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

// values defined with the given `config` 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

.is

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

.isRegistered

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`
});

.use

Define a plugin function to be called immediately upon init.

Params

• fn {Function}: plugin function to call
• returns {Object}: Returns the item instance for chaining.

Example

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

.define

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

// arbitrary `render` function using lodash `template`
app.define('render', function(str, locals) {
  return _.template(str)(locals);
});

.base

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'

Base.use

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'

Toolkit suite

Base is used as the foundation for all of the applications in the toolkit suite (except for enquirer):

Building blocks

• base: (you are here!) framework for rapidly creating high quality node.js applications, using plugins like building blocks.
• templates: API for managing template collections and rendering templates with any node.js template engine. Can be used as the basis for creating a static site generator, blog framework, documentaton system, and so on.
• enquirer: composable, plugin-based prompt system (Base is used in prompt-base, the core prompt module that powers all prompt plugins)

Lifecycle

Developer frameworks and command line tools that address common phases of the software development lifecycle. Each of these tools can be used entirely standalone, but they work even better together.

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

Tests

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

Release History

key

Changelog entries are classified using the following labels from keep-a-changelog:

• added: for new features
• changed: for changes in existing functionality
• deprecated: for once-stable features removed in upcoming releases
• removed: for deprecated features removed in this release
• fixed: for any bug fixes

Custom labels used in this changelog:

• dependencies: bumps dependencies
• housekeeping: code re-organization, minor edits, or other changes that don't fit in one of the other categories.

Heads up!

Please let us know if any of the following heading links are broken. Thanks!

0.12.0

Fixed

• ensure __callbacks and super_ are non-enumberable

Added

• Now sets app.type when app.is('foo') is called. This allows Base instances to be used more like AST nodes, which is especially helpful with smart plugins

0.11.0

Major breaking changes!

• Static .use and .run methods are now non-enumerable

0.9.0

Major breaking changes!

• .is no longer takes a function, a string must be passed
• all remaining .debug code has been removed
• app._namespace was removed (related to debug)
• .plugin, .use, and .define no longer emit events
• .assertPlugin was removed
• .lazy was removed
