Monorepo

A monorepo (short for "monolithic repository") is a source code management approach where multiple projects or modules are stored in a single version control repository. Instead of having separate repositories for each project or microservice, all the code is kept together in a single repository.

Advantages of a Monorepo

  1. Simplified Management: Having all projects in a single place makes it easier to manage dependencies and versions.

  2. Consistency: Using consistent versions of libraries and services is easier, as everything is controlled from a single repository.

  3. Easier Collaboration: Collaboration between teams is improved, as all developers have access to the same repository and can see changes in real-time.

  4. Simple Refactoring: Refactorings that affect multiple projects can be done more safely and simply, as all modules are in the same repository.

Monorepo Structure

A typical monorepo structure might include directories for different modules, such as libraries and microservices. For example:

monorepo/
├── libs/               # Common libraries
│   └── AuthGuard/     # Authentication and authorization library
└── microservices/      # Microservices
    ├── usermanagement/  # User management microservice
    ├── feedbackrequest/  # Feedback request microservice
    └── feedbackresponse/ # Feedback response microservice

Monorepo Management

  1. Build and Tests: You can build and test all modules at once, making code maintenance easier.

  2. Adding New Modules: To add new microservices or libraries, you just need to create a new directory and configure the corresponding module.

  3. Refactoring: Since all projects are in the same repository, refactorings that affect multiple services or libraries can be done more safely and in a coordinated manner.

  4. Versioning: Versioning can be managed centrally, ensuring that all services and libraries are using the same dependency versions.

  5. Dependency Management: The monorepo approach helps define dependency versions in a single place, avoiding conflicts and making it easier to update versions.
