Monorepo Builder Laravel Package

Product Decisions This Supports

• Monorepo Adoption: Enables a shift from multi-repo to monorepo architecture for PHP projects, reducing dependency management complexity and improving cross-package consistency.
• Developer Experience (DX): Streamlines package versioning, dependency resolution, and release workflows, reducing manual errors and developer onboarding time.
• Scalability: Supports large codebases with shared dependencies, reducing duplication and simplifying CI/CD pipelines.
• Build vs. Buy: Eliminates the need to build custom scripts for monorepo management, saving engineering time and reducing technical debt.
• Roadmap Alignment: Aligns with trends toward modular, composable architectures (e.g., microservices, shared libraries) while maintaining backward compatibility.
• Open-Source Ecosystem: Leverages existing PHP tooling (Composer) to avoid vendor lock-in, ensuring long-term maintainability.

When to Consider This Package

• Adopt when:

  • Managing 5+ interdependent PHP packages in separate repos becomes cumbersome (e.g., version skew, dependency conflicts).
  • Teams need faster release cycles with automated version validation and propagation.
  • Cross-package refactoring is frequent (e.g., shared utilities, APIs), and a monorepo would reduce merge conflicts.
  • CI/CD pipelines are bloated due to redundant dependency checks or manual release steps.
  • The project uses PHP 8.2+ and Composer as its package manager.

• Look elsewhere if:

  • Your project is small or isolated (1–3 packages with no shared dependencies).
  • You’re using non-PHP languages or a polyrepo (e.g., Nx, Turborepo) that already handles cross-language monorepos.
  • Your team lacks Composer expertise or prefers alternative tools (e.g., composer-merge-plugin, custom scripts).
  • You need advanced monorepo features like cross-language support, fine-grained dependency isolation, or IDE tooling (e.g., JetBrains Gateway for PHP).
  • The project has legacy PHP versions (<8.1) or non-standard Composer setups.

How to Pitch It (Stakeholders)

For Executives/Stakeholders:

"This package lets us consolidate our PHP packages into a single monorepo, cutting release time by 40% and reducing dependency conflicts. It automates version management, merges package configs, and enforces consistency—like GitHub’s monorepo tools but for PHP. This aligns with our goal of [faster iterations/scalability/cost savings] while keeping our stack open-source. The MIT license and active maintenance (last release: May 2026) make it a low-risk choice."

For Engineering Teams:

*"Monorepo Builder solves our pain points with:

• Single-source truth: No more composer.json duplication or version hell.
• Automated releases: One command (release) handles version bumps, changelogs, and tags across packages.
• CI/CD efficiency: Merged composer.json reduces pipeline steps, and propagate ensures changes ripple correctly.
• Flexibility: Works with existing Composer workflows—no rewrite needed. Tradeoff: Initial setup requires defining a monorepo-builder.php config, but the long-term gains outweigh it. We can pilot it with [Package X] to validate before full adoption."*

For Developers:

*"This tool turns our messy multi-repo setup into a clean monorepo with minimal friction:

• Init: Scaffolds a packages/ structure in 1 command.
• Merge: Combines all composer.json files into the root (no more copying require sections).
• Release: Handles version bumps, Git tags, and changelog updates across packages—just run release v1.0. Bonus: It validates versions to prevent breaking changes. Let’s try it on [Project Y] and see how it feels!"*
