API Platform and Symfony helpers to deploy on Heroku

This library eases the deployment of API Platform and Symfony applications on the Heroku platform.

Install

Use Composer to install the library in your project:

composer require dunglas/api-platform-heroku

Database helper

The library provides a Composer script to create Symfony parameters for the Doctrine bundle by parsing the DATABASE_URL environment variable populated by the Heroku Postgres addon.

To use it, start by adding the script to your composer.json file:

// ...
    "scripts": {
        "pre-install-cmd": [
          "Dunglas\\Heroku\\Database::createParameters"
        ],
        // ...
    }

Thanks to the ability of the Symfony Dependency Injection Component to read parameters from special environment variables, the parameters are automatically populated.

Change the content of the app/config/services.yml like the following to use them:

doctrine:
    dbal:
        driver:   "pdo_pgsql"
        host:     "%database_host%"
        port:     "%database_port%"
        dbname:   "%database_name%"
        user:     "%database_user%"
        password: "%database_password%"
        charset:  UTF8

In your local development environment, don't forget to set the SYMFONY__DATABASE_URL environment variable. A typical value for that variable is `postgres://user:pass@server:5432/dbname.

A convenient way to manage environment variable is the PHP dotenv library.
