Laravel Heroku Config Parser

Parse Heroku config vars like DATABASE_URL or REDIS_URL to work with Laravel.

Important

Due to a breaking change in Laravel 5.8 (thanks https://github.com/mathieutu for the feedback), you can use this method to achieve the same goal:

Why

When adding a database or a redis server to your Heroku app, Heroku add a URL config var like this: DATABASE_URL=postgres://usr:pwd@localhost:5432/hellodb

Unfortunately, Laravel can't read this var, so you probably parsed it manually like this:

heroku config:set DB_CONNECTION=pgsql
heroku config:set DB_HOST=localhost
heroku config:set DB_PORT=5432
heroku config:set DB_DATABASE=hellodb
heroku config:set DB_USERNAME=usr
heroku config:set DB_PASSWORD=pwd

Laravel Heroku Config Parser parse automatically your DATABASE_URL and REDIS_URL to dynamically set all vars needed by Laravel (see the list).

Installation

Installation using composer:

composer require itsdamien/laravel-heroku-config-parser

Heroku

Add these config vars:

heroku config:set KEY_DATABASE=DATABASE_URL
heroku config:set KEY_REDIS=REDIS_URL

Laravel

Add this block code to the top of your config/database.php:

if (class_exists('\ItsDamien\Heroku\Config\Parse')) {
    new \ItsDamien\Heroku\Config\Parse();
}

Enjoy !

ENV vars created

Customize the config var who will be parsed

You can select wich config var will be parsed by setting KEY_DATABASE and KEY_REDIS like this:

heroku config:set KEY_DATABASE=HEROKU_POSTGRESQL_BRONZE
heroku config:set KEY_REDIS=REDIS_URL_BACKUP
