Polyrepo/Monorepo Management Documentation

1. Monorepo Flavor

Monorepos can be organized in various ways depending on the project requirements. Here are three common types:

Standalone-Based Monorepo

• Description: Projects are isolated from each other but reside within the same repository. Each project manages its own dependencies and configurations.
• Use Case: Suitable for projects that need clear separation but benefit from shared tooling and versioning.

Package-Based Monorepo

• Description: The repository is organized into multiple packages, each with its own package.json or configuration file. These packages are often interdependent.
• Use Case: Ideal for projects where packages share common dependencies and code, such as libraries and tools used together.

Integrated Monorepo-Based

• Description: All projects and their dependencies are tightly integrated, often with a single set of configurations and shared code.
• Use Case: Best for projects that need a high level of interdependency and cohesive version management.

For more information on different flavors of monorepos, you can refer to this Medium Article.

2. Buildable and Publishable Project

In a monorepo setup, projects can be configured to be buildable and publishable. This involves setting up build and deployment processes, managing dependencies, and ensuring compatibility.

Key Concepts

• Buildable Projects: Projects that can be compiled or transpiled into deployable artifacts.
• Publishable Projects: Projects that can be released or distributed, often including steps for publishing to package registries or artifact repositories.

For details on setting up project dependency rules and configurations, see Nx Project Dependency Rules.

3. Pipeline Task

Pipeline management in a monorepo involves running tasks efficiently and handling dependencies between tasks. Nx provides tools to streamline this process.

Key Commands

• Run a Specific Task:

  #!/bin/sh
  npx nx run <task> <project>

Example: npx nx run build my-project

• Run Multiple Tasks:

  #!/bin/sh
  npx nx run-many -t <tasks>

Example: npx nx run-many -t build lint test e2e cache

• Run Affected Tasks:

  #!/bin/sh
  npx nx affected -t <tasks>

Example: npx nx affected -t build lint test e2e cache
