What is Hotfix Branch in Gitflow: Definition and Usage

A hotfix branch in Gitflow is a special branch created to quickly fix critical bugs in the production code without waiting for the next release cycle. It is branched off from main and merged back into both main and develop branches after the fix is applied.

How It Works

Imagine your software is like a car on the road. Sometimes, a sudden problem appears that needs immediate fixing, like a flat tire. The hotfix branch in Gitflow is like pulling over quickly to fix that flat tire without waiting for your regular maintenance schedule.

In Gitflow, the hotfix branch starts from the main branch, which holds the current production-ready code. You create this branch to fix urgent bugs that affect users. Once the fix is done, you merge the changes back into main to update the live product and also into develop so the fix is included in future releases.

This process keeps your production stable while allowing your team to continue working on new features in develop.

Example

This example shows how to create a hotfix branch, fix a bug, and merge the changes back.

bash

git checkout main
git pull origin main

git checkout -b hotfix/urgent-fix
# Make your bug fix here

git add .
git commit -m "Fix critical bug in production"

git checkout main
git merge hotfix/urgent-fix
git push origin main

git checkout develop
git merge hotfix/urgent-fix
git push origin develop

git branch -d hotfix/urgent-fix

Output

Switched to branch 'main'
Already up to date.
Switched to a new branch 'hotfix/urgent-fix'
[hotfix/urgent-fix abc1234] Fix critical bug in production
Switched to branch 'main'
Merge made by the 'recursive' strategy.
To https://your-repo-url.git
   abc1234..def5678  main -> main
Switched to branch 'develop'
Merge made by the 'recursive' strategy.
To https://your-repo-url.git
   def5678..ghi9012  develop -> develop
Deleted branch hotfix/urgent-fix (was abc1234).

When to Use

Use a hotfix branch when you find a serious bug in your live product that needs an immediate fix. This could be a security issue, a crash, or a major feature broken in production.

It is not for regular feature development or minor fixes that can wait for the next release cycle. Hotfixes help keep your users happy by quickly solving urgent problems without disrupting ongoing work.

For example, if your website checkout process suddenly fails, you create a hotfix branch to fix it fast and deploy the fix right away.

Key Points

• A hotfix branch is for urgent fixes on production code.
• It branches from main and merges back into main and develop.
• It allows quick fixes without stopping new feature work.
• Use it only for critical bugs, not regular updates.

Key Takeaways

A hotfix branch fixes urgent production bugs quickly without waiting for the next release.

It starts from main and merges back into main and develop to keep all branches updated.

Use hotfix branches only for critical issues that affect users immediately.

Merging hotfixes into develop ensures the fix is included in future releases.

Hotfixes keep production stable while allowing ongoing feature development.
