gh-events

Github Events Emitter

This module will poll the Events API and emit events as it sees them.

This is useful for places where you can't have a public webhook to consume these events.

install

npm i gh-events --save

usage

const GHEvents = require('./index');

const evts = new GHEvents({
    org: 'yahoo',
    auth: { //optional
        type: 'basic',
        username: '<username>',
        password: '<token>'
    }
});

evts.start();

evts.on('fork', (event, payload) => {
    console.log(event, payload);
});

evts.on('all', (event, payload) => {
    console.log(event, payload);
});

authentication

Supports the authentication used in the github module. The auth config Object should be the value passed to the authenticate method. If no auth is given then your script will be subject to the stricter rate limiting rules.

configuration

All options are optional. If org, repo and user are all omitted then all github events will be polled.

• org - Listen for org level events
• user- Listen for user level events
• repo - Listen for user/repo events (requires user)
• auth - See above
• userAgent - A string to use as the userAgent when talking to the api

events

The module will emit 5 types of events, mostly named after the event it is consuming. In this example we will use the PushEvent. More details on the events from Github can be found in their docs.

• PushEvent
• Push
• pushevent
• push
• all

The module will try to clean up the event name and emit the event any way that it can. You can listen to the all event to receive events for every event that is found.

caching

The module will abide by Github's rules for polling. It uses the X-Poll-Interval header that it receives to limit the amount of time between polls to ensure that it stays as a "good api citizen". It also stores the latest etag header and sends that along on the following requests and only acts on data that is new.

It also stores the etag, poll time and latest event id to disk after each fetch so that if the script is restarted it will continue on from where it left off. This will keep events from being fired off twice.
