component-api

API for creating, building, and installing components. If you're looking for a command line interface, see component(1)

Installation

$ npm install component-api

Usage

var api = require('component-api');

api.build(directory, options, callback)

Build a component in the given directory. It returns an event emitter so you can view progress.

arguments:

directory

string path for the directory containing the component you wish to build

options

dev

True to include development dependencies

standalone

If present, indicates that a standalone build should be created which exports the global with name `standalone`

out

The output directory for built files, defaults to `./build`.

You can alternatively pass an object of the form: `{js: Stream, css: Stream}`

name

The base name for the output files - defaults to `build`

prefix

prefix css asset urls with `prefix`

callback(err, duration)

Gets passed how long the build took in milliseconds.

events:

`writing to`

Gets called with `{js, css}` containing the streams being written to. Use `js.path` to get the path of the JavaScript file being written.

`writing`

Gets called with `{js, css}` containing the number of bytes being written to each file.

api.convert(file, callback)

Convert a text file into require'able JavaScript

arguments:

file

Path to the file as a string

callback(err)

Called once the converted file is written to disk

api.fetch(packageName, version, destination, options, callback)

Download a repo into a folder and return the component.json file as parsed json. N.B. This doesn't download dependencies, you'll need to use install for that.

example:

api.fetch('component/emitter', '*', './', {}, function (err) {
  if (err) throw err;
  api.install('./', [], {}, function (err) {
    if (err) throw err;
    api.build('./', {standalone: 'EventEmitter'}, function (err) {
      if (err) throw err;
      console.log('built standalone event emitter');
    })
  });
})

arguments:

packageName

`:user/:repo` the package name to download

version

The version of the package to download.

destination

The directory to download the package to.

options

remote

The remote to fetch from (defaults to `https://raw.github.com`)

OR

remotes

The remotes to fetch from. Takes precedence over remote if both are present. Each remote in the array will be tried until one of them returns JavaScript or there are no more left to try.

And

force

re-install modules even if they aren't out of date.

ignore

An object hash of any modules you want to ignore, used internally.

auth

`{user, pass}`

api.install(directory, pkgs, options, callback)
