Parsing all the JSON events from your Gitlab HTTP callbacks

Language Build Status Release Licence

gitlab-webhooks.cr

GitLab can trigger events with well configured webhooks. When that event occurs, the source app makes an HTTP request to the URI configured for the webhook, you can use the Crystal HTTP class to manage that. The action taken may be anything... Common uses are to trigger builds with continuous integration systems or to notify deployments.

Docs Generated in latest commit.

Installation

  1. Add the dependency to your shard.yml:
dependencies:
  gitlab-webhooks:
    github: chussenot/gitlab-webhooks
    version: 0.3.3
  1. Run shards install

Usage

You just have to require the lib.

require "gitlab-webhooks"

The Crystal language is new ... Crystal has downsides just like every other languages. To relay the catched Gitlab events on hundreds of Ruby, Python libraries made by thousands of open source contributors over the last decade or monitoring systems like Prometheus, few examples can be find below. You can contribute and add your example in the examples folder.

HTTP requests

This Crystal example show you how to implement where all endpoints can catch some events, parse them and print the values of some attributes.

require "json"
require "http/server"
require "gitlab-webhooks"

server = HTTP::Server.new do |context|
  if body = context.request.body
    event : Gitlab::Event = Gitlab.event_from(JSON.parse(body).to_json.to_s)
    puts event.commit.message
    context.response.content_type = "text/plain"
    context.response.print "Hello world!"
  else
    context.response.print "You didn't POST any data :("
  end
end

server.bind_tcp 8080
puts "Listening on http://0.0.0.0:8080"
server.listen

Then you can curl the server with a sample file

curl -X POST --data @data.json http://localhost:8080/
