Version Control for Micro Frontends

1. Introduction

Version control is essential for managing the lifecycle of micro frontends. It ensures that teams can collaborate effectively, maintain code integrity, and deploy features independently.

2. Key Concepts

Understanding the following concepts is vital for effective version control in micro frontends:

Micro Frontends: An architectural style that allows independent development of frontend applications.
Version Control Systems (VCS): Tools that help manage changes to source code over time.
Branching and Merging: Techniques to manage different development streams in VCS.
Continuous Integration/Continuous Deployment (CI/CD): Practices to automate the deployment of code changes.

3. Version Control Strategies

Choosing the right version control strategy is crucial for micro frontends. Here are common strategies:

Single Repository (Monorepo)
Multiple Repositories (Polyrepo)

3.1 Single Repository (Monorepo)

All micro frontends are stored in a single repository, which simplifies dependency management and versioning.

3.2 Multiple Repositories (Polyrepo)

Each micro frontend has its own repository, allowing teams to manage them independently.

Example: Setting Up a Monorepo

git init my-micro-frontends
cd my-micro-frontends
mkdir frontend1 frontend2 frontend3
# Create a package.json file for managing dependencies
npm init -y

4. Best Practices

Implementing best practices in version control can lead to smoother workflows:

Use meaningful commit messages.
Adopt a consistent branching strategy.
Regularly sync changes with the main branch to avoid conflicts.
Implement code reviews before merging changes.

5. FAQ

What is a Monorepo?

A monorepo is a single repository that contains multiple micro frontends, allowing for easier management of shared dependencies.

What are the benefits of using a Polyrepo?

A polyrepo allows teams to work independently on different micro frontends, reducing the risk of conflicts and enabling targeted deployments.

How do I handle versioning in a Monorepo?

Utilize tools like Lerna or Nx to manage versioning and dependencies within a monorepo.
