Git Branching Strategies That Actually Work for Small Teams

Introduction

As a developer working in small teams, I've had the opportunity to experiment with different Git branching strategies. In this article, I'll share my experience with Git Flow, GitHub Flow, and trunk-based development, and recommend one that actually works for small projects.

Git Flow

Git Flow is a complex branching model that was introduced by Vincent Driessen in 2010. It's designed for large projects with multiple releases and a long development cycle. The main branches in Git Flow are master and develop, and there are also feature, release, and hotfix branches.

Here's an example of how to create a feature branch using Git Flow:

git flow feature start my-feature

While Git Flow is well-structured, it can be overwhelming for small teams. The multiple branches and strict workflow can lead to unnecessary complexity.

GitHub Flow

GitHub Flow is a simpler branching model that's designed for small teams and projects with a short development cycle. It's based on a single master branch, and feature branches are created from master and merged back into master when they're complete.

Here's an example of how to create a feature branch using GitHub Flow:

git checkout -b my-feature

GitHub Flow is lightweight and easy to understand, but it can lead to a messy master branch if not managed properly.

Trunk-Based Development

Trunk-based development is a branching model that's designed for teams that want to release software quickly and frequently. It's based on a single trunk branch, and all changes are made directly to trunk. Feature branches are short-lived and merged into trunk as soon as possible.

Here's an example of how to create a feature branch using trunk-based development:

git checkout -b my-feature
git merge my-feature

Trunk-based development is ideal for small teams that want to release software quickly, but it requires a high degree of automation and testing to ensure that trunk is always stable.

Comparison

| Branching Model | Complexity | Release Cycle | Team Size | | --- | --- | --- | --- | | Git Flow | High | Long | Large | | GitHub Flow | Low | Short | Small | | Trunk-Based Development | Medium | Short | Small |

Recommendation

For small projects with 2-5 developers, I recommend using GitHub Flow. It's simple, easy to understand, and allows for a short development cycle. While it can lead to a messy master branch if not managed properly, this can be mitigated by using automated testing and continuous integration.

Practical Takeaways

  • Use GitHub Flow for small projects with a short development cycle
  • Keep feature branches short-lived and merge them into master as soon as possible
  • Use automated testing and continuous integration to ensure that master is always stable
  • Consider using trunk-based development if you want to release software quickly and frequently
  • Avoid using Git Flow for small teams, as it can lead to unnecessary complexity
