Deploy Laravel on Heroku

TLDR

To deploy Laravel project on Heroku, we just need to create new app on Heroku dashboard, add environment variables on settings, connect GitHub repository, configure Profile and push the project to GitHub. Heroku will re-deploy the app whenever we push code to connected repository.

Prerequisite

I expect you already have GitHub and Heroku account. If you don't, please register and comeback again.

• Register GitHub here
• Register Heroku here

Setup Laravel

Here I use fresh Laravel project. To create the project, use command below.

laravel new l8-on-laravel

HINT
I expect you was installed composer and laravel/installer. If you don't, please install it first.

Create a file named Procfile. Place it in your root project directory. This file is responsible to run our migration tables, caching events, optimization command and configure the web server that we want to use.

HINT
Heroku has a feature called Releases. The advantages of this feature are we can use a pre-build script to run migration tables, caching file, etc.

Read more about releases and its phase.

Put this into the Procfile.

release: ./scripts/release.sh
web: vendor/bin/heroku-php-nginx -C nginx_app.conf public/

Here I use NGINX as web server because for me it's easier to configure. I also pass a custom NGINX configuration to prevent 404 error.

Create a new file called nginx_app.conf and put this into the file.

location / {
    # try to serve file directly, fallback to rewrite
    try_files $uri @rewriteapp;
}

location @rewriteapp {
    # rewrite all to index.php
    rewrite ^(.*)$ /index.php/$1 last;
}

location ~ ^/index\.php(/|$) {
    try_files @heroku-fcgi @heroku-fcgi;
    # ensure that /index.php isn't accessible directly, but only through a rewrite
    internal;
}

Last, create a shell file named scripts/release.sh to run optimization on framework level.

#!/bin/sh

php artisan migrate --force;
php artisan optimize;
php artisan event:cache;

And make sure to mark the file as executable (for public) otherwise Heroku can not run the file for us.

Setup GitHub repository

Create a new repository. Give it a name as you like. I use l8-on-heroku for the repository name.

After that, commit and push the project to the repository.

git init
git add .
git commit -m "initial commit"
git remote add origin git@github.com:thexdev/l8-on-heroku.git
git push origin main

You can check this post if you don't know how to use ssh for your repository.

Setup and deploying to Heroku

First we need to create a new app on Heroku.

Give our app a name. Here I use l8-on-heroku. You can use any name you like, but ensure it uses lowercase letters and doesn't contain any special characters except dashes (-).

After that, add all environment variables that exist in your Laravel .env file.

Go to settings...

Click reveal config vars...

Fill the config vars.

Now, connect our app with the project repository. This feature will build and re-deploy the app whenever we push changes to the repository.

Select the repository. For my case the repository is l8-on-heroku.

Enable auto deploys...

And finally deploy the app.

Now, check the app and here my result l8-on-heroku.
