What is a feature branch?

A feature branch in Git is a temporary working branch intended for developing a single specific piece of functionality (a feature) isolated from the project's main branch.

#Main idea

A feature branch lets you develop a new capability without the risk of breaking the main branch and without conflicts with the parallel work of other developers.

#How and from where it is created

• usually created from the main branch (main);
• contains only changes related to a single task;
• lives until the feature is finished.

#Why it is needed

#1. Isolation of changes

In a feature branch:

• you can experiment freely;
• bugs and unfinished code do not reach the stable version;
• the main branch stays clean and working.

#2. Parallel development

• each task is a separate branch;
• several features can be developed at the same time;
• the number of conflicts is reduced.

#3. Convenience of review and testing

• changes for a single feature are easy to review;
• it is easier to understand what exactly the feature adds;
• convenient for running checks and tests.

#What happens next

• after development is finished, the feature branch is:
  • merged into the main branch (merge or rebase),
  • or deleted, if the feature is cancelled;
• after merging, the branch is usually no longer needed.

#Naming (a commonly used approach)

• feature/auth
• feature/payment
• feature/add-search
• sometimes with a task number: feature/123-user-profile

#Short definition

A feature branch is a separate branch for developing a single piece of functionality, created from the main branch and deleted after it is merged.
