Building a Hacker News Reader with Lumen
In this tutorial, we’re going to build a reader for Hacker News. We will be using the Hacker News API and the Lumen framework to implement this.
The final output looks something like this:
If you’re excited, let’s go ahead and jump right into it.
The first thing that you need to do is to install Lumen. You can do so with the following command, where hnreader is the folder you want the project installed into and --prefer-dist just speeds up the download of the required Composer packages:
composer create-project laravel/lumen hnreader --prefer-dist
Create an .env file with the contents:
APP_DEBUG=true APP_TITLE=HnReader DB_CONNECTION=mysql DB_HOST=localhost DB_PORT=3306 DB_DATABASE=hnreader DB_USERNAME=homestead DB_PASSWORD=secret
APPDEBUG allows us to turn on debugging in Lumen so that we can see the errors in the app. And the DB* is for the database configuration. We will be using the MySQL database for storing the items that we will be getting from the Hacker News API. This way, we won’t need to make a separate HTTP request every time a user accesses the app. You will probably just leave the values for DB_CONNECTION, DB_HOST, DB_PORT as they are if you’re using Homestead Improved. Of course, we need to create the database, too.
