metahub

A per-repo, always-up-to-date cache of Github's meta-data (like issues, PRs, and comments). Great for speeding up requests and avoiding running over GitHub's API limits.

What is it good for?

Long-running services that want to frequently calculate/respond to metrics based on Github Issues, PRs, and comments. Metahub was created for Mary Poppins, a tool for helping to manage issues and PRs on populat Github repos.

For a more lightweight approach, you might want to look into:

• node-github

Usage

var config = {
  // Github repo to watch
  // https://github.com/myname/myrepo
  target: {
    user: 'myname',
    repo: 'myrepo'
  },

  // credentials for user who leaves comments, etc
  login: {
    username: 'myrobotname',
    password: 'supersecretpassword'
  },

  // You may also use basic token authentication in place of username and password
  // by generating a personal access token at 
  // https://github.com/settings/applications 
  
  //login: {
  //  username: 'yourTokenHere3098438ef098dsf709834',
  //  password: 'x-oauth-basic'
  //},

  // port to listen on,
  // and URL for Github to ping
  hook: {
    url: 'http://example.com:1234',
    port: 1234
  }
};

var meta = require('metahub')(config);

meta.on('issueReopened', function (data) {
  console.log('this issue was reopened: ' + data.number);
});

meta.start();

How does it work?

First, metahub makes a bajillion requests to Github to scrape all the data. Then, it launches an Express instance and uses Github's WebHooks API to stay up-to-date.

API

Uses promises (sorry, not sorry).

makeMeta(config)

Metahub factory;

var makeMeta = require('metahub');
var config = {
  // etc...
};
var meta = makeMeta(config);

Metahub

Useful if you want to extend Metahub:

var util = require('util');
var Metahub = require('metahub').Metahub;

var MyHub = function MyHub () {
  Metahub.apply(this, arguments);
};

util.inherits(MyHub, Metahub);

---

meta.issues

This property contains all of the issue info scraped from Github, organized by number.

console.log(meta.issues[1347].title);
// -> "The Issue Title"

meta.repo

This property contains all of the repo info scraped from Github:

console.log(meta.repo);
// -> { "id": 1296269, "owner": { ... }, "name": "Hello-World", ... }

---

meta.start()

Starts the Github hook server, which listens to the port specified in the config.

---

meta.getCommits(number)

Returns the commits for the specified PR.

meta.createComment(number, body)

Creates a comment for the specified issue/PR with the given moarkdown-formatted body.
