Gith NPM | npm.io

gith

githooks - a simple node server that responds to github post-receive events with meaningful data

Getting Started

Install

Install the module with: npm install gith

Require

In your node application, require gith and create a gith server. You can specify a port now, or you can use the .listen( portNumber ) method later.

// create a gith server on port 9001
var gith = require('gith').create( 9001 );

Use

Pass an object of how you want to filter gith (if at all) and subscribe to an event.

gith({
  repo: 'danheberden/gith'
}).on( 'all', function( payload ) {
  console.log( 'Post-receive happened!' );
});

Hook

Be sure github.com is sending payload data to your server. From your repository root go to Admin > Service Hooks > WebHook URLs and add your server url, e.g., http://mycoolserver.com:9001.

Filtering

The object passed into gith() can utilize four parameters (repo, branch, file and tag). All of these can either be an exact match string, a regular expression or a function.

For example:

gith({
  repo: 'danheberden/gith',
  branch: /issue_(\d+)/
}).on( 'branch:add', function( payload ) {
  console.log( 'A branch matching /issue_(\d+)/ was added!' );
  console.log( 'The issue # is', payload.matches.branch[1] );
});

You can either omit the key that you don't want to filter (e.g., we would get every file and tag in the above example) or use * to specifiy that it's a wildcard.

Events

Events available are:

all - as long as the filtering passed, this will get fired
branch:add
branch:delete
file:add
file:modify
file:delete
file:all
tag:add
tag:delete

Payload

The github payload is very detailed, but can be a bit excessive.

This is the payload that gith gives you:

{
  original: the-original-github-payload,
  files: {
    all: [],
    added: [],
    deleted: [],
    modified: []
  },
  tag: tag, /* if a tagging operation */
  branch: branch, /* if working on a branch */
  repo: the-repo-name,
  sha: the-now-current-sha,
  time: when-it-was-pushed,
  urls: {
    head: current-sha
    branch: branch-url-if-available,
    tag: sha-url-of-tag-if-available,
    repo: repo-url,
    compare: compare-url
  },
  reset: did-the-head-get-reset,
  pusher: github-username-of-pusher,
  owner: github-username-of-repo-owner
}
