A GitHub Action to streamline installation of PHP dependencies with Composer.

ramsey/composer-install is a GitHub Action to streamline installation of Composer dependencies in workflows. It installs your Composer dependencies and caches them for improved build times.

This project adheres to a code of conduct. By participating in this project and its community, you are expected to uphold this code.

This GitHub Action requires PHP and Composer. One way to ensure you have both is to use the Setup PHP GitHub Action.

The step that sets up PHP and Composer for your environment must come before the ramsey/composer-install step.

Use ramsey/composer-install as step within a job. This example also shows use of the Setup PHP action as a step.

- uses: "shivammathur/setup-php@v2"
  with:
    php-version: "latest"
- uses: "ramsey/composer-install@v2"

💡 There is no need to set up a separate caching step since ramsey/composer-install handles this for you.

The dependency-versions input parameter allows you to select whether the job should install the locked, highest, or lowest versions of Composer dependencies.

Valid values are:

• locked: (default) installs the locked versions of Composer dependencies (equivalent to running composer install)

• highest: installs the highest versions of Composer dependencies (equivalent to running composer update)

• lowest: installs the lowest versions of Composer dependencies (equivalent to running composer update --prefer-lowest --prefer-stable)

For example:

- uses: "ramsey/composer-install@v2"
  with:
    dependency-versions: "lowest"

ramsey/composer-install always passes the --no-interaction, --no-progress, and --ansi options to the composer command. If you'd like to pass additional options, you may use the composer-options input parameter.

For example:

- uses: "ramsey/composer-install@v2"
  with:
    composer-options: "--ignore-platform-reqs --optimize-autoloader"

The working-directory input parameter allows you to specify a different location for your composer.json file. For example, if your composer.json is located in packages/acme-foo/, use working-directory to tell ramsey/composer-install where to run things.

- uses: "ramsey/composer-install@v2"
  with:
    working-directory: "packages/acme-foo"

You may use this step as many times as needed, if you have multiple composer.json files.

For example:

# Install dependencies using composer.json in the root.
- uses: "ramsey/composer-install@v2"

# Install dependencies using composer.json in src/Component/Config/
- uses: "ramsey/composer-install@v2"
  with:
    working-directory: "src/Component/Config"

# Install dependencies using composer.json in src/Component/Validator/
- uses: "ramsey/composer-install@v2"
  with:
    working-directory: "src/Component/Validator"

If you have jobs for which you wish to completely ignore the caching step, you may use the ignore-cache input parameter. When present, ramsey/composer-install will neither read from nor write to the cache.

Values of 'yes', true, or 1 will tell the action to ignore the cache. For any other value, the action will use the default behavior, which is to read from and store to the cache.

- uses: "ramsey/composer-install@v2"
  with:
    ignore-cache: "yes"

There may be times you wish to specify your own cache key. You may do so with the custom-cache-key input parameter. When provided, ramsey/composer-install will not use the auto-generated cache key, so if your composer.json or composer.lock files change, you'll need to update the custom cache key if you wish to update the cache.

- uses: "ramsey/composer-install@v2"
  with:
    custom-cache-key: "my-custom-cache-key"

GitHub Workflows allow you to set up a job matrix, which allows you to configure multiple jobs for the same steps by using variable substitution in the job definition.

Here's an example of how you might use the dependency-versions and composer-options input parameters as part of a job matrix.

strategy:
  matrix:
    php:
      - "7.4"
      - "8.0"
      - "8.1"
    dependencies:
      - "lowest"
      - "highest"
    include:
      - php-version: "8.2"
        composer-options: "--ignore-platform-reqs"

steps:
  - uses: "actions/checkout@v2"
  - uses: "shivammathur/setup-php@v2"
    with:
      php-version: "${{ matrix.php }}"
  - uses: "ramsey/composer-install@v2"
    with:
      dependency-versions: "${{ matrix.dependencies }}"
      composer-options: "${{ matrix.composer-options }}"
