Using Composer to Manage a Project

You can use composer to manage a project by including a composer.json file alongside of your .lando.yml file and adding a build step to run composer install for your project. Let's get started.

  • Adding in a composer install build step
  • Adding composer managed tools like phpunit and phpcs
  • Adding composer test scripts section in composer.json
    • Run your phpunit and phpcs tests with lando composer test

Generate a Project Directory and a composer.json File

Use this composer command to generate the composer.json file for your project:

composer create-project drupal-composer/drupal-project:~7.0 composer-drupal7 --stability dev --no-interaction

Change into that directory:

cd composer-drupal7

Generate a .lando.yml File for your Project

You can issue lando init and name the app composer-drupal7

lando init --recipe drupal7 --name composer-drupal7

Output should be similar to:

[email protected] composer-drupal7 $ init --name composer-drupal7
? What recipe do you want to use? drupal7
? Where do you want to create this app? /Users/geoff/code/composer-drupal7
? Where is your webroot relative to the init destination? web


Your app has been initialized.
Now try running `lando start` to get rolling.

Here are some vitals:

 NAME    composer-drupal7
 RECIPE  drupal7

That should generate the following .lando.yml file:

name: composer-drupal7
recipe: drupal7
  webroot: web

Adding a build Step to Your .lando.yml File

Adding the build step to run composer install allows you to pass off your app to your team members with just the composer.json file and they will be able to pull in all the dependencies by just running lando start!

Open your .lando.yml file and add the following services section:

    # Add a Build Step to your App.
      - "cd $LANDO_MOUNT && composer install"

Now whenever you restart or start your app it will pull in all the necessary dependencies via composer! For example if your colleague adds pathauto to the project via composer require drupal/pathauto. Then all you need to do is git pull and then restart your app with lando restart and you will have pathauto too!

Adding phpunit and Tooling Route

You can add in additional composer managed packages easily. Let's add phpunit. At the command line type:

lando composer require phpunit/phpunit --dev

Open your .lando.yml file and add the following:

    service: appserver
    description: "Run PHP Unit tests: lando phpunit"

Restart your app: lando restart. Now let's add a scripts section to our composer.json file. We can use the scripts key and have composer run our unit tests via phpunit.

Open your composer.json file and add in:

"scripts": {
    "test": [
        "./vendor/bin/phpunit || true"

Now you can run the command:

lando composer test

and that will run phpunit for you. Let's define a simple unit test. First add a phpunit.xml file to the root of your project. You can copy this:

<?xml version="1.0" encoding="UTF-8"?>
<phpunit backupGlobals="false"
        <testsuite name="Application Test Suite">
            <directory suffix=".php">web/</directory>
        <env name="APP_ENV" value="testing"/>
        <env name="CACHE_DRIVER" value="array"/>
        <env name="SESSION_DRIVER" value="array"/>
        <env name="QUEUE_DRIVER" value="sync"/>

Make a tests directory in the root of your app.

mkdir tests

Add your first test! Create a file in the tests directory named StackTest.php and paste in the following code:

use PHPUnit\Framework\TestCase;

class StackTest extends TestCase
    public function testPushAndPop()
        $stack = [];
        $this->assertEquals(0, count($stack));

        array_push($stack, 'foo');
        $this->assertEquals('foo', $stack[count($stack)-1]);
        $this->assertEquals(1, count($stack));

        $this->assertEquals('foo', array_pop($stack));
        $this->assertEquals(0, count($stack));

        print "\n\n\tGeoff is the best.\n\n";

Now running lando composer test will run your first Unit Test! Well Done! you can read more about PHPUnit here:

Add phpcs and Drupal Coding Standards

Let's add phpcs, drupal/coder, and add linting to the scripts key in composer.json. Then we will have automated code linting helping to keep our code bases lean and mean.

lando composer require overtrue/phplint --dev
lando composer require squizlabs/php_codesniffer:2.7.0 --dev
lando composer require drupal/coder:8.2.9 --dev

Add a .phplint.yml configuration file to tell what code to test and what to ignore. Put the .phplint.yml file in the root of your app.

path: ./web/sites/all
  - php
  - module
  - inc
  - install
  - modules/contrib
  - libraries

Add the linting and code standards to the test section of composer.json:

"scripts": {
  "test": [
    "./vendor/bin/phpunit || true",
    "./vendor/bin/phplint --configuration=.phplint.yml --no-cache ./web/sites/all/modules/custom",
    "./vendor/bin/phpcs --standard=./vendor/drupal/coder/coder_sniffer/Drupal ./web/sites/all/modules/custom --extensions=php,inc,module,install"

Now running the command:

lando composer test

runs your PHPUnit tests, code linting and code style checks! Well done to you!
