Not only Composer tools to build a Monorepo

Downloads total

Do you maintain a monorepo with more packages?

This package has few useful tools, that will make that easier.

Install

composer require symplify/monorepo-builder --dev

Usage

1. Are you New to Monorepo?

The best to lean-in fast is to read basic intro at blog post All You Always Wanted to Know About Monorepo. We also made a simple command to make that easy for you:

vendor/bin/monorepo-builder init

And the basic setup is done!

2. Merge local composer.json to the Root One

Merges configured sections to the root composer.json, so you can only edit composer.json of particular packages and let script to synchronize it.

Sections that are needed for monorepo to work will be merged:

  • 'require'
  • 'require-dev'
  • 'autoload'
  • 'autoload-dev'
  • 'repositories'
  • 'extra'

To merge run:

vendor/bin/monorepo-builder merge

Typical location for packages is /packages. But what if you have different naming or extra /projects directory?

use Symplify\MonorepoBuilder\ComposerJsonManipulator\ValueObject\ComposerJsonSection;
use Symplify\MonorepoBuilder\Config\MBConfig;
use Symplify\MonorepoBuilder\ValueObject\Option;

return static function (MBConfig $mbConfig): void {
    // where are the packages located?
    $mbConfig->packageDirectories([
        // default value
        __DIR__ . '/packages',
        // custom
        __DIR__ . '/projects',
    ]);

    // how to skip packages in loaded directories?
    $mbConfig->packageDirectoriesExcludes([__DIR__ . '/packages/secret-package']);

    // "merge" command related

    // what extra parts to add after merge?
    $mbConfig->dataToAppend([
        ComposerJsonSection::AUTOLOAD_DEV => [
            'psr-4' => [
                'Symplify\Tests\\' => 'tests',
            ],
        ],
        ComposerJsonSection::REQUIRE_DEV => [
            'phpstan/phpstan' => '^0.12',
        ],
    ]);

    $mbConfig->dataToRemove([
        ComposerJsonSection::REQUIRE => [
            // the line is removed by key, so version is irrelevant, thus *
            'phpunit/phpunit' => '*',
        ],
        ComposerJsonSection::REPOSITORIES => [
            // this will remove all repositories
            Option::REMOVE_COMPLETELY,
        ],
    ]);
};

3. Bump Package Inter-dependencies

Let's say you release symplify/symplify 4.0 and you need package to depend on version ^4.0 for each other:

vendor/bin/monorepo-builder bump-interdependency "^4.0"

4. Keep Synchronized Package Version

In synchronized monorepo, it's common to use same package version to prevent bugs and WTFs. So if one of your package uses symfony/console 3.4 and the other symfony/console 4.1, this will tell you:

vendor/bin/monorepo-builder validate

5. Keep Package Alias Up-To-Date

You can see this even if there is already version 3.0 out:

{
    "extra": {
        "branch-alias": {
            "dev-master": "2.0-dev"
        }
    }
}

Not good. Get rid of this manual work and add this command to your release workflow:

vendor/bin/monorepo-builder package-alias

This will add alias 3.1-dev to composer.json in each package.

If you prefer 3.1.x-dev over default 3.1-dev, you can configure it:

use Symplify\MonorepoBuilder\Config\MBConfig;

return static function (MBConfig $mbConfig): void {
    // default: "<major>.<minor>-dev"
    $mbConfig->packageAliasFormat('<major>.<minor>.x-dev');
};

6. Split Directories to Git Repositories

Thanks to GitHub Actions, this was never simpler to set up. Use symplify/github-action-monorepo-split.

How to configure it? See our local setup at .github/workflows/split_monorepo.yaml

7. Release Flow

When a new version of your package is released, you have to do many manual steps:

  • bump mutual dependencies,
  • tag this version,
  • git push with tag,
  • change CHANGELOG.md title Unreleased to v<version> - Y-m-d format
  • bump alias and mutual dependencies to next version alias

But what if you forget one or do it in wrong order? Everything will crash!

The release command will make you safe:

vendor/bin/monorepo-builder release v7.0

And add the following release workers to your monorepo-builder.php:

use Symplify\MonorepoBuilder\Config\MBConfig;
use Symplify\MonorepoBuilder\Release\ReleaseWorker\AddTagToChangelogReleaseWorker;
use Symplify\MonorepoBuilder\Release\ReleaseWorker\PushNextDevReleaseWorker;
use Symplify\MonorepoBuilder\Release\ReleaseWorker\PushTagReleaseWorker;
use Symplify\MonorepoBuilder\Release\ReleaseWorker\SetCurrentMutualDependenciesReleaseWorker;
use Symplify\MonorepoBuilder\Release\ReleaseWorker\SetNextMutualDependenciesReleaseWorker;
use Symplify\MonorepoBuilder\Release\ReleaseWorker\TagVersionReleaseWorker;
use Symplify\MonorepoBuilder\Release\ReleaseWorker\UpdateBranchAliasReleaseWorker;
use Symplify\MonorepoBuilder\Release\ReleaseWorker\UpdateReplaceReleaseWorker;

return static function (MBConfig $mbConfig): void {
    // release workers - in order to execute
    $mbConfig->workers([
        UpdateReplaceReleaseWorker::class,
        SetCurrentMutualDependenciesReleaseWorker::class,
        AddTagToChangelogReleaseWorker::class,
        TagVersionReleaseWorker::class,
        PushTagReleaseWorker::class,
        SetNextMutualDependenciesReleaseWorker::class,
        UpdateBranchAliasReleaseWorker::class,
        PushNextDevReleaseWorker::class,
    ]);
};

These TagVersionReleaseWorker and PushTagReleaseWorker are enabled by default. If you want to disable these default workers, you can use the following code.

return static function (MBConfig $mbConfig): void {
    $mbConfig->disableDefaultWorkers();
};

You can also include your own workers. Just add services that implements ReleaseWorkerInterface. Are you afraid to tag and push? Use --dry-run to see only descriptions:

vendor/bin/monorepo-builder release 7.0 --dry-run

Do you want to release next patch version, e.g. current v0.7.1 → next v0.7.2?

vendor/bin/monorepo-builder release patch

You can use minor and major too.
