Octo.js

Octo.js is a simple, flexible, functional JavaScript library for interacting with GitHub's v3 API. It runs in node.js apps and the browser. It supports Basic Auth, OAuth 2, pagination and more.

Requires superagent — A lightweight library for supporting Ajax in the browser and HTTP in node.js.

All examples are written in CoffeeScript, but Octo.js itself is written in JavaScript.

Quick Example

api = octo.api()
api.get('/events').on('success', (res) ->
  pubevents = res.body
)()

api.get sets up a closure, so you'll need to invoke it before the request is sent.

events = api.get('/events').perpage(50)
  .on 'end', (res) ->
    console.log api.limit()
    console.log events.page() #1

events()

Using in the browser

Download both superagent and octo.js and include them in the <head> of your document.

  <script src="superagent.js"></script>
  <script src="octo.js"></script>

Using in node.js

Install using npm.

npm install octo

Require octo in your node.js script

octo = require 'octo'

Paging

One goal of octo.js was to make paging very simple. Paging is built right into the library.

events = api.get('/events').on('success', (res) ->
  # the current page
  events.page()

  # requests the next page
  events.next()

  # requests the previous page
  events.prev()
)
events()

What if you want to start on a different page and limit the number of results per page?

# Start on page 5 only returning 10 results per page
api.get('/events').page(5).perpage(10)()

Events

Octo.js supports three events: "success", "error" and "end". These callbacks are registered per pager. This makes it easy to use the same callbacks for each page you request.

success - Response status was in the 200 range
error - Response wasn't in the 200 range
end - Fired at the end of every request, regarldess of status.

events = api.get('/events')
  .on('success', (res) -> console.log(res.body))
  .on('error', (res) -> console.log(res.body))
  .on('end', (res) -> console.log(res.body))()

Basic Auth

api = octo.api().username('foo').password('bar')
api.get('/user').on('success', (res) -> console.log(res.body))()

OAuth2

If you've registered your script or app as an OAuth app, you can use your token to authenticate with the api.

api = octo.api().token('MY APP TOKEN')
api.get('/user').on('success', (res) -> console.log(res.body))()

This will work with any registered OAuth application, but will return unauthorized if you've not registered your application with GitHub.

Getting an OAuth 2 token from the API

GitHub APIv3 allows you to programmatically fetch a token for use in scripts that might not be websites. Grabbing an OAuth token requires a username and password. Once you have a token, you can use it without a need for your username and password.

api = octo.api().username('foo').password('bar')
api.post('/authorizations', {note: 'my script', scopes: ['public_repo']})
   .on('success', (res) -> console.log(res.body))()

Checking Rate limits

The GitHub API has a rate limit that's returned with the headers of every request. You can easily access this info to see your limit and how many requests you have left

api.get('/users/caged/repos').on('success', ->
  # Your limit per hour
  console.log api.limit()

  # Amount you have remaining in that hour
  console.log api.remaining()
)()
