Craft 3 - Heroku Boilerplate

Yes this is a rocket

To make sure we can seamlessly work in teams, we have a specific requirements for our hosting environment. Currently, our hosting solution of choice is Netlify and Heroku. Netlify is mostly for our static websites. Heroku is for almost all other projects. With Craft 3, which was released in April’18, it’s already much easier to install the CMS as a composer package and host it. But there were still some things we needed to take care of in order to host it on Heroku.

This is a guide on how to set up a Craft 3 project on Heroku.

The quick and dirty start

This button has been made for those who just want to have a fresh Craft 3 instance on Heroku. Click the button and directly deploy our public boilerplate repository to a new instance on your Heroku account.

Go ahead and try: Deploy

After the install process, visit the URL of your app and add /admin/install to it. For example: https://YOUR-URL-GOES-HERE.herokuapp.com/admin/install

Fill out all the details from the guide and you are good to go! Heroku create new app screen

Start from scratch

Set up a new project

First we need to clone our Boilerplate Repo into a local folder:

  $ git clone git@github.com:edenspiekermann/craft-heroku-boilerplate.git

Rename the folder and make it your project:

  $ mv craft-heroku-boilerplate NEW-PROJECT-NAME

Now we need to remove the Github connection and connect the folder with your own Git repository.

  $ cd craft-heroku-boilerplate
  $ rm -rf .git
  $ git init
  $ git add .
  $ git commit -m '🎈 project start 🎈'

Go and create a new and empty Git repository with your account. There must not be any .git or README.md file. After it is created, go with:

  $ git remote add origin YOUR-REMOTE-PROJECT-URL
  $ git push --set-upstream origin master

Use it

Deploy to Heroku

To make your repository work on Heroku, we first have to update the reference URL with your freshly created repository. Heroku reads all the deploy details from the app.json file. So we need to replace the "repository" URL with your repository YOUR-REMOTE-PROJECT-URL.

Push the changed app.json to your GitHub repository and adjust the following link with your repository and branch: https://heroku.com/deploy?template=https://github.com/YOUR-REMOTE-PROJECT-URL/tree/YOUR-BRANCH-NAME

For example: https://heroku.com/deploy?template=https://github.com/edenspiekermann/craft3-heroku-starterkit/tree/master

After you adjusted the link, visit it in your browser. You will see a Heroku page for creating a new instance. Heroku create new app screen

It will also install a free plan of a MariaDB and connect it with Craft. Please fill out all the details and don’t forget to choose the region. If you are in Europe, please use Europe and US if you are in the US or nearby. If you choose the wrong region, it could be that your website is slower than it could be.

If you have multiple Users, it is recommended, that you upgrade at least the database to a paid plan. It can happen, that the max_connections of the free database plan is used up, when you have too much database traffic. This means, that you can not access the website anymore (Error 500) and you have to upgrade the database plan.

Depending on the traffic, you also may have to upgrade the Heroku servers to a paid plan.

Heroku Post install

After the deployment process is successful, go to your new created website and add /admin/install to the URL. Craft will help you to make the setup complete. Craft CMS install screen

Use it locally

To complete your development environment, you should make the project running on your local machine as well:

$ composer install
Having troubles with PHP extensions?

If you have any issues with missing php extensions during composer install command, you have to make sure the extension ext-mbstring and ext-imagick are installed. For OSX, it is best to install imagemagick and php (must be >7) with homebrew and imagick with pecl (PHP extension manager):

  $ brew install imagemagick
  $ brew install pkg-config
  $ pecl install imagick

Start working with the project

Plugins which come with the project

Cloudinary

Craft3 Cloudinary is an integration of the cloud-based image management cloudinary to your Craft3 project.

Set up Cloudinary in Craft

  1. Go to your Admin -> Settings -> Assets
  2. Create a new Volume
  3. Type in a name you like (f.e. Cloud Images)
  4. Enable Assets in this volume have public URLs
  5. You can decide on your Base URL (f.e. @web is the root of your website but you can also go with @web/images if you want to have http://yourwebsite.com/images/ as your public image path)
  6. Volume Type must be Cloudinary
  7. Now fill in the Cloudinary credentials
  8. Go to the Assets and upload the first image

Blitz

The Blitz Plugin is only for production. It is a intelligent static file caching for creating lightning-fast sites. If you enable this, your site will be very fast, but you will not see the debugger toolbar. So make sure to disable it in development from the admin panel.

Redactor

Most projects do need a wysiwyg editor. Redactor claims to be the most advanced and human-friendly one. Well … it is a very nice and customisable editor. GitHub

Gatekeeper

If the page is still under construction, it is a good idea to password protect it. Therefore we use Gatekeeper.

Important notice

Database

If you want to develop locally, I can highly recommend you to use a local database, otherwise the website will be quite slow. To change the database, head over to your .env variable, change the value of JAWSDB_MARIA_URL and restart the server.

Procfile

Craft has its main folder not in the root directory (in this project it is the web folder), so we need to do some adjustments on the Heroku web server settings. Heroku provides optional configurations in the Procfile. In this project we need to start an Nginx as a web server and make web the root directory of the server.

I would recommend to not change the name of the web folder. If you feel like changing it, please read the Docs and don’t forget to change the folder path after the boot-script in the Procfile.

Database

This project is using MariaDB instead of MySQL. MariaDB is a complete drop-in-replacement for MySQL. If you need to migrate some datas, you should not have problems here. If you do, you can change the database connection at any time in the Heroku interface by replacing the JAWSDB_MARIA_URL URL with your database URL (settings --> config vars).
