A Hubot-compatible Github API wrapper for Node.js

Install

npm install githubot

Require

Use it in your Hubot script:

module.exports = (robot) ->
  github = require('githubot')(robot)

Or use it on its own:

github = require('githubot')

Specify a different Github API version (default is beta):

module.exports = (robot) ->
  github = require('githubot')(robot, apiVersion: 'preview')

Use

Make any call to the Github v3 API, get the parsed JSON response:

github.get "https://api.github.com/users/iangreenleaf/gists", (gists) ->
  console.log gists[0].description

github.get "users/foo/repos", {type: "owner"}, (repos) ->
  console.log repos[0].url

data = { description: "A test gist", public: true, files: { "abc.txt": { content: "abcdefg" } } }
github.post "gists", data, (gist) ->
  console.log gist.url

Authentication

If process.env.HUBOT_GITHUB_TOKEN is present, you're automatically authenticated. Sweet!

Acquire a token

If you don't have a token yet, run this:

curl -i https://api.github.com/authorizations -d '{"scopes":["repo"]}' -u "yourusername"

Enter your Github password when prompted. When you get a response, look for the "token" value.

Handling errors

GitHubot will log errors automatically if it has a logger. Used with Hubot, these will go to the Hubot logger.

If your script would like to catch errors as well, define an extra callback:

github.handleErrors (response) ->
  console.log "Oh no! #{response.statusCode}!"

The callback takes a response argument with the following keys:

• error: The error message.
• statusCode: The status code of the API response, if present.
• body: The body of the API response, if present.

Helpful Hubot

If process.env.HUBOT_GITHUB_USER is present, we can help you guess a repo's full name:

github.qualified_repo "githubot" # => "iangreenleaf/githubot"

This will happen with the bespoke methods as well:

gh.branches "githubot", (branches) ->

Options

• HUBOT_GITHUB_TOKEN: GitHub API token. Required to perform authenticated actions.

• HUBOT_GITHUB_USER: Default GitHub username to use if one is not given.

• HUBOT_GITHUB_API: The base API URL. This is useful for Enterprise Github installations.

  For example, HUBOT_GITHUB_API='http://myprivate.github.int'

• HUBOT_CONCURRENT_REQUESTS: Limits the allowed number of concurrent requests to the GitHub API. Defaults to 20.

Bespoke API access

Mostly a work in progress, but here's a taste of what I have in mind:

List branches

gh.branches "foo/bar", (branches) ->
  console.log branches[0].name

Create a branch

# Branch from master
gh.branches( "foo/bar" ).create "my_radical_feature", (branch) ->
  console.log branch.sha

# Branch from another branch
gh.branches( "foo/bar" ).create "even_more_radical", from: "my_radical_feature", (branch) ->
  console.log branch.sha

Merge a branch

# Merge a branch into master
gh.branches( "foo/bar" ).merge "my_radical_feature", (mergeCommit) ->
  console.log mergeCommit.message

# Merge a branch into a different target
gh.branches( "foo/bar" ).merge "my_radical_feature", into: "hotfixes", (mergeCommit) ->
  console.log mergeCommit.message

# `base` is an alias for `into`
gh.branches( "foo/bar" ).merge "my_radical_feature", base: "hotfixes", (mergeCommit) ->
  console.log mergeCommit.message

# Provide your own commit message
gh.branches( "foo/bar" ).merge "my_radical_feature", message: "Merge my radical feature!", (mergeCommit) ->
  console.log mergeCommit.sha

Delete a branch

gh.branches( "foo/bar" ).delete "my_radical_feature", ->
  console.log "Deleted my branch!"

Contributing

Install the dependencies:

npm install

Run the tests:

make test
make test-all # Runs additional slower "integration" style tests, generally not necessary

Pull requests encouraged!

I'm vastly more likely to merge code that comes with tests. If you're confused by the testing process, ask and I can probably point you in the right direction.

Thanks

These lovely people have contributed to githubot.
