README

PHP Monorepository Utility PMU (PHP Monorepo Utility) is a Composer plugin specifically designed to facilitate PHP monorepo management. It provides commands for running operations on single or multiple projects, synchronizing dependencies, and blending shared configurations. PMU simplifies dependency handling and automation across interconnected packages, ensuring efficient development and maintenance in monorepositories.

Installation

composer require --dev soyuka/pmu
composer global require --dev soyuka/pmu # ability to link projects globally

Configuration

// composer.json
{
  "name": "test/monorepo",
  // Specify the projects that are part of your monorepository
  "extra": {
    "pmu": {
        "projects": ["./packages/*/composer.json"]
    }
  },
  "config": {
      "allow-plugins": {
          "soyuka/pmu": true
      }
  }
}

Note that repositories are propagated to each project when running commands from the base composer.json file. An example is available in the tests/monorepo directory.

Commands

Run a command on a single project

composer [project-name] [args]

For example: composer test/a install.

Run a command on every projects

composer all install

Runs composer install on every projects.

For example to change the branch alias:

composer all config extra.branch-alias.dev-main 3.3.x-dev -vvv

Blend dependencies

Blend your root composer.json constraints in each of the projects.

composer blend [--dev] [--all] [--self] [--json-path=JSON-PATH] [--value=VALUE] [project-name]

Note: there's no dry mode on this command, use a VCS to rollback on unwanted changes.

When project-a depends on dependency-a:^2.0.0 and your root project has dependency-a:^3.0.0, running composer blend will set the requirement of dependency-a to ^3.0.0 in project-a.

We do not check if a dependency is valid, you should probably run composer all validate or composer all update after running this.

Blend can also transfer any json path:

composer blend --json-path=extra.branch-alias.dev-main --force

Or blend a given value:

composer blend --json-path=extra.branch-alias.dev-main --force --value=4.x

Where force will write even if the value is not present in the project's composer.json.

When you want to bump all your mono-repository's dependencies and ignore the rest use --self, this is quite handy with the --all option, on API Platform we use this to align every dependency of our mono-repository (eg: set every version to the ones defined on our root composer.json):

composer blend --all --self

Run a graph of dependencies

composer graph [project-name]

Example: composer graph test/a to see the dependencies for the test/a project.

Checks dependencies

This script reads the code and detect use classes. It then checks that the dependencies are correctly mapped in the require or require-dev of each project.

composer check-dependencies

Link

To link your project's mono-repository dependencies use composer link. This will create a temporary composer definition with:

  • configured repository on each project's path
  • add a @dev constraint to force composer to run local symlinks
  • run composer update
  • revert the definition to the previous ones (we recommend running this command after setting up a version control system)

You can run this command on a global install to link a directory to the current project:

composer global link ../the-mono-repository --working-directory=$(pwd)

TODO:

  • create and affected graph to be able to run tests on affected projects
