Git Flow and Branching Models
Why Have a Strategy?
When teams work together, they need rules about how to use branches. Without rules, you get chaos — merge conflicts everywhere, broken code in production, and confused developers.
Strategy 1: GitHub Flow (Simple)
Best for: Small teams, web apps, continuous deployment.
main ──────────────────────────── (always deployable)
\ /
feature ───── (short-lived, merged via PR)
Rules
mainis always deployable- Create a branch for every change
- Open a Pull Request
- After review, merge to main
- Deploy immediately
Pros & Cons
| ✅ Pros | ❌ Cons |
|---|---|
| Simple to understand | No staging environment |
| Fast deployment cycle | Less control over releases |
| Great for small teams | Not ideal for scheduled releases |
Strategy 2: Git Flow (Structured)
Best for: Large teams, scheduled releases, mobile apps.
main ───────────────────── (production releases)
\ /
develop ──────────────────── (integration branch)
\ /
feature ─────── (individual features)
Branches
| Branch | Purpose | Merges Into |
|---|---|---|
| <code>main</code> | Production code | — |
| <code>develop</code> | Integration | main |
| <code>feature/</code> | New features | develop |
| <code>release/</code> | Prepare a release | main + develop |
| <code>hotfix/*</code> | Emergency fixes | main + develop |
Strategy 3: Trunk-Based Development
Best for: Experienced teams, CI/CD, frequent releases.
main ─────────────────────── (everyone commits here)
\ / \ / \ /
── ── ── (very short-lived branches)
Rules
- Everyone works on
main(or very short branches) - Commits are small and frequent
- Feature flags hide incomplete features
- Automated tests catch problems
Which Strategy Should You Use?
| Team Size | Release Style | Recommended |
|---|---|---|
| 1-3 people | Continuous | GitHub Flow |
| 4-20 people | Scheduled | Git Flow |
| 20+ people | Continuous | Trunk-Based |
Summary
Start with GitHub Flow — it's the simplest and works for most projects. As your team grows, consider Git Flow or Trunk-Based Development.
