remotes

Remotes.js

The goal of this repo is to normalize different remote endpoints for Component into a unified API. You can also create your own remote endpoints instead of shoehorning different APIs into a JSON file. This also handles versions and git trees, which is a little more complicated than just github raw.

Example:

var Remotes = require('remotes');
var remotes = Remotes();
remotes.use(new Remotes.Local({
  dir: 'components'
}));
remotes.use(new Remotes.GitHub({
  auth: 'jonathanong:password'
}));
 
co(function* () {
  // get the correct remote from a list of remotes
  var remote = yield* remotes.resolve('component/emitter');
  // return all the versions this remote has
  var versions = yield* remote.versions('component/emitter');
  // do stuff with the versions
})

A shortcut for the above is:

var remotes = require('remotes')(['github'], {
  local: true,
  dir: 'components',
  netrc: '',
})

Where netrc points to a netrc file. See netrc.

Using Remotes

var remotes = new Remotes([names], [options])

Returns a group of remotes. names is a list of redefined remotes. Note that order matters.

The current remotes are:

• remotes.github
• remotes.bitbucket
• remotes.local - use downloaded components

The list of names can be found at Remotes.remotes.

Some options are:

• netrc - for netrc
• dir - local components path. Defaults to `process.cwd() + '/components'
• local - use the local component.

remotes.use(remote)

Add a remote to this list of remotes. Note that order matters.

var remote = yield* remotes.resolve([names], repo, [ref])

Returns the first remote with <repo>@<ref> from the list of remotes. You may optionally pass names, a list of remote names, instead of searching all the remotes or to search in a different order.

Authentication

Some remotes, such as GitHub, require authentication. We suggest you use netrc.

For Github, you need to supply you username and password for the api.github.com host. You may also set the GITHUB_USERNAME and GITHUB_PASSWORD environmental variables. Similarly, for BitBucket, you set BITBUCKET_USERNAME and BITBUCKET_PASSWORD.

Using a Remote

remote.name

The name of the remote.

var json = yield* remote.json(repo, [ref])

Return the component.json of a component from this remote.

var versions = yield* remote.versions(repo)

Get all valid semver version of this remote.

var tree = yield* remote.tree(repo, ref)

Return the git tree of this repo. Will return a list of objects with properties:

• path - file path in the repo
• sha - sha1 check sum
• fize - file byte length

var urls = remote.file(repo, ref, path)

Return an array of absolute URLs of where to download this component's file path.

var archive = remote.archive(repo, ref)

Return an object containing absolute URLs of where to download this repo's archive. archive is of the format archive[format] = urls[]. Example:

{
  tar: [
    'https://api.github.com/repos/component/emitter/tarball/master',
  ],
  zip: [
    'https://api.github.com/repos/component/emitter/zipball/master',
  ]
}

Remote Notes

• Only master is supported as the default branch.

BitBucket

• Git trees are not supported, so please don't use globs in your component.jsons!

Creating your own Remote

You may create your own remote. See the remotes for implementation examples.

Remotes.Remote.extend(Child)

Extend a new Remote class with the current Remote. Example:

var Remote = require('remotes').Remote;
 
function GitHub(options) {
  options = options || {}
  Remote.call(this, options)
 
  this.something = 'asdf'
}
 
Remote.extend(GitHub)
 
Github.prototype.something = function () {
 
}

Implementable Functions

The following properties must be implemented. Note that if you want a remote to be skipped, simply return null.

• .name
• ._json()
• ._versions()
• ._tree()
• .file()
• .archive()

If a function is not supported, simply do not define it. For example, BitBucket does not support git trees, so ._tree() is not defined.
