justfile-polyglot-patterns

What problem does it solve?

This Skill solves the challenge of coordinating multi-language monorepos by providing a root-level justfile that delegates work to subprojects.

Core Features & Use Cases

• Root-level orchestration delegates tasks to subprojects, avoiding duplication and ensuring consistent interfaces.
• Each subproject maintains its own standalone justfile, enabling independent lifecycles while still supporting unified workflows.
• The _run-all helper enables deterministic, fail-fast delegation across multiple subprojects (e.g., api and web).
• Use cases include installing dependencies, running checks, building artifacts, and deploying across a polyglot codebase.

Quick Start

1. Create a root justfile that delegates to subprojects via a _run-all helper and ensure each subproject has its own justfile.
2. Populate subprojects (e.g., api, web) with their own interfaces; keep root minimal and orchestration-focused.
3. From the repository root, run just dev-install to set up all environments, then just check-all to validate the whole project.
