Breaking changes

  • Methods no longer set values on the root of the instance. By default, .get, .get, .has, .del and other method use the base.cache object. This can be customized by doing new Base.create('foo') where foo is the property name to use for the cache.

Why use Base?

Base is a foundation for creating modular, unit testable and highly pluggable server-side node.js APIs.

  • Go from zero to working application within minutes
  • Use community plugins to add feature-functionality to your application
  • Create your own custom plugins to add features
  • Like building blocks, plugins are stackable. Allowing you to build sophisticated applications from simple plugins. Moreover, those applications can also be used as plugins themselves.

Most importantly, once you learn Base, you will be familiar with the core API of all applications built on Base. This means you will not only benefit as a developer, but as a user as well.

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 dramatically simplifies inheritance.

  • Easy to test: No special setup should be required to unit test Base or base plugins

  • 100% Node.js core style

    • No API sugar (left for higher level projects)
    • Written in readable vanilla JavaScript

Minimal API surface

The API was designed to provide only the minimum necessary functionality for creating a useful application, with or without plugins.

Base core

Base itself ships with only a handful of useful methods, 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:

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

Add "smart plugin" functionality with the base-plugins plugin.

Inheritance

Easily inherit Base using .extend:

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:

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'

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 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

.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

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)

.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

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

cache object

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);

Toolkit suite

Base is part of the Toolkit suite of applications.

What is Toolkit?

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.

About

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
