Development & Testing

All development on BookStack is currently done on the development branch.
When it's time for a release the development branch is merged into release with built & minified CSS & JS then tagged at its version. Here are the current development requirements:

Node.js v16.0+

Building CSS & JavaScript Assets

This project uses SASS for CSS development and this is built, along with the JavaScript, using a range of npm scripts. The below npm commands can be used to install the dependencies & run the build tasks:

# Install NPM Dependencies
npm install

# Build assets for development
npm run build

# Build and minify assets for production
npm run production

# Build for dev (With sourcemaps) and watch for changes
npm run dev

BookStack has many integration tests that use Laravel's built-in testing capabilities which makes use of PHPUnit. There is a mysql_testing database defined within the app config which is what is used by PHPUnit. This database is set with the database name, username and password all defined as bookstack-test. You will have to create that database and that set of credentials before testing.

The testing database will also need migrating and seeding beforehand. This can be done by running composer refresh-test-database.

Once done you can run composer test in the application root directory to run all tests. Tests can be ran in parallel by running them via composer t. This will use Laravel's built-in parallel testing functionality, and attempt to create and seed a database instance for each testing thread. If required these parallel testing instances can be reset, before testing again, by running composer t-reset.

If the codebase needs to be tested with deprecations, this can be done via uncommenting the relevant line within the TestCase@setUp function.

Code Standards

We use tools to manage code standards and formatting within the project. If submitting a PR, formatting as per our project standards would help for clarity but don't worry too much about using/understanding these tools as we can always address issues at a later stage when they're picked up by our automated tools.

PHP

PHP code standards are managed by using PHP_CodeSniffer.
Static analysis is in place using PHPStan & Larastan.
The below commands can be used to utilise these tools:

# Run code linting using PHP_CodeSniffer
composer lint

# As above, but show rule names in output
composer lint -- -s

# Auto-fix formatting & lint issues via PHP_CodeSniffer phpcbf
composer format

# Run static analysis via larastan/phpstan
composer check-static

JavaScript

JavaScript code standards use managed using ESLint.
The ESLint rule configuration is managed within the package.json file.
The below commands can be used to lint and format:

# Run code linting using ESLint
npm run lint

# Fix code where possible using ESLint
npm run fix

Development using Docker

This repository ships with a Docker Compose configuration intended for development purposes. It'll build a PHP image with all needed extensions installed and start up a MySQL server and a Node image watching the UI assets.

To get started, make sure you meet the following requirements:

Docker and Docker Compose are installed
Your user is part of the docker group

If all the conditions are met, you can proceed with the following steps:

Copy .env.example to .env, change APP_KEY to a random 32 char string and set APP_ENV to local.
Make sure port 8080 is unused or else change DEV_PORT to a free port on your host.
Run chgrp -R docker storage. The development container will chown the storage directory to the www-data user inside the container so BookStack can write to it. You need to change the group to your host's docker group here to not lose access to the storage directory.
Run docker-compose up and wait until the image is built and all database migrations have been done.
You can now login with admin@admin.com and password as password on localhost:8080 (or another port if specified).

If needed, You'll be able to run any artisan commands via docker-compose like so:

docker-compose run app php artisan list

The docker-compose setup runs an instance of MailHog and sets environment variables to redirect any BookStack-sent emails to MailHog. You can view this mail via the MailHog web interface on localhost:8025. You can change the port MailHog is accessible on by setting a DEV_MAIL_PORT environment variable.

Running tests

After starting the general development Docker, migrate & seed the testing database:

# This only needs to be done once
docker-compose run app php artisan migrate --database=mysql_testing
docker-compose run app php artisan db:seed --class=DummyContentSeeder --database=mysql_testing

Once the database has been migrated & seeded, you can run the tests like so:

docker-compose run app php vendor/bin/phpunit

Debugging

The docker-compose setup ships with Xdebug, which you can listen to on port 9090.
NB : For some editors like Visual Studio Code, you might need to map your workspace folder to the /app folder within the docker container for this to work.
