Monorepo Discipline: Turborepo, Boundaries, and CI

Monorepo discipline with Turborepo: workspaces, cached pipelines, import boundaries, versioning with Changesets, and CI basics.

Goals

  • Fast builds, clear ownership, safe API boundaries

1) Workspaces

  • Use pnpm or yarn workspaces for deterministic installs
  • One package per purpose: apps/, packages/, tooling/*

2) Task pipelines

  • Turborepo with local and remote cache in CI
  • Consistent scripts: build, dev, test, lint, typecheck

3) Boundaries

  • ESLint rules and TS path mapping to enforce imports
  • No deep imports across packages. Re-export from index

4) Versioning and releases

  • Changesets for versions and changelogs
  • Publish only public packages. Keep internals private

5) Testing strategy

  • Unit tests isolated per package
  • E2E in apps and run against preview deployments

6) DX

  • Strict tsconfig.base.json at the root
  • Shared Prettier and ESLint in a tooling package

Example: turbo.json

{
  "$schema": "https://turbo.build/schema.json",
  "pipeline": {
    "build": { "dependsOn": ["^build"], "outputs": ["dist/**"] },
    "dev": { "cache": false },
    "lint": { "outputs": [] },
    "typecheck": { "outputs": [] },
    "test": { "outputs": ["coverage/**"] }
  }
}

Checklist

  • Cached pipelines
  • Strict boundaries and clear ownership
