monorepo（monorepo 开发）

Monorepo Architecture

Use this skill to create predictable package boundaries, shared tooling, and fast incremental builds.

Use This Skill When

• Multiple apps share code and release cadence.
• You need shared packages (ui, types, config, utils).
• Build/test/lint pipelines need workspace-level orchestration.

Core Contract

1. Keep deployable apps in apps/.
2. Keep reusable packages in packages/.
3. Use workspace protocol dependencies (workspace:*).
4. Use Turbo pipelines for dependency-aware task execution.
5. Keep environment variables explicit per app/package boundary.

Recommended Structure

apps/
packages/
turbo.json
pnpm-workspace.yaml
package.json

Implementation Workflow

1) Workspace Setup

• Configure pnpm-workspace.yaml.
• Define root scripts for dev, build, lint, test.
• Add Turbo pipeline with dependsOn and outputs.

2) Shared Packages

• Create packages/ui, packages/types, packages/config.
• Export public APIs from package roots.
• Keep package boundaries strict and testable.

3) App Integration

• Consume shared packages via workspace deps.
• Keep app-specific runtime config local to app.
• Avoid hidden coupling through root-only env assumptions.

4) Operational Quality

• Cache-friendly tasks and deterministic outputs.
• Per-package ownership and CI filters.
• Versioning/release strategy documented.

Output Requirements for Agent

• Folder layout proposal.
• Workspace and Turbo config.
• Shared package strategy.
• CI/build command matrix.
