App that listens Github events via webhooks and exposes an endpoint to filter it by issues.

Since it is a learning project, some language structures has its usage forced, still these usages are open to discussions

• Kotlin
• Javalin
• Spring Framework (boot, data)
• PostgreSQL
• Apache Maven
• JUnit

Assuming that you already have the technologies above pre-installed (if needed), clone the repository and install its dependencies.

# clone this repository
$ git clone https://github.com/douglasgabriel/octo-events-kotlin.git

# go inside the repository
$ cd octo-events-kotlin

# install dependencies
$ mvn clean install

Also you may want to configure your local database by changing the src/main/resources/application.properties file

The test suite can be executed by the following command

$ mvn test

To run locally this project you will need to provide a public URL that routes to your local endpoint, so, the use of ngrok is recommended here.

$ ngrok http 3000

The default port is 3000, but it is possible to change it on file src/main/resources/application.properties

Then it is possible to run the project by the following command:

$ mvn spring-boot:run

Github Events listener

The app defines the following endpoint to listen to Github events

[POST] /events

To integrate this APP with Github, you can navigate to the page of choosed repository, and then navigate to settings -> Webhooks and click on Add Webhook button. Finally you can fill the Payload URL field with $public_url/events and submit.

Now, when you create and update a Issue inside the choosed repository, the Github will request the given Payload URL, and then the APP will persist the Event and the associated Issue in database.

Filter events by Issue

The app also defines the following endpoint to get every Event of a particular Issue

# where number is the issue number
[GET] /issues/:number/events
