1. Introduction

Versioning is an essential practice in software development that involves assigning version numbers to releases of software products. For JavaScript projects, versioning not only helps in tracking the evolution of the codebase but also communicates the impact of changes to developers and users. This guide provides a detailed approach to managing versioning in JavaScript projects using GitHub, covering everything from versioning strategies to automation and troubleshooting.

2. Versioning Strategy

Semantic Versioning (SemVer)

Semantic Versioning is a standardized versioning scheme that conveys meaning about the nature of changes in each release. The format is:

MAJOR.MINOR.PATCH

Version Numbering

1. Major Version (MAJOR):

   • Definition: Incremented for changes that introduce backward-incompatible changes.

   • When to Increment:

     • Removal of public APIs or breaking changes in existing functionality.

     • Changes that require users to adjust their existing code or configurations.

   • Example: Upgrading from 2.0.0 to 3.0.0 might indicate a complete overhaul of the library's API or core functionality.

2. Minor Version (MINOR):

   • Definition: Incremented for backward-compatible new features or improvements.

   • When to Increment:

     • Adding new features that do not disrupt existing functionality.

     • Enhancements that are additive and do not affect the existing API.

   • Example: Moving from 1.1.0 to 1.2.0 could involve adding new utility functions or modules that extend functionality.

3. Patch Version (PATCH):

   • Definition: Incremented for backward-compatible bug fixes and minor improvements.

   • When to Increment:

     • Fixing bugs that do not affect the API or existing features.

     • Making corrections that enhance stability or performance without introducing new features.

   • Example: Updating from 1.0.0 to 1.0.1 might address a security vulnerability or minor bug.

• Semantic Versioning Specification

3. Branching Strategy

GitFlow Workflow

GitFlow is a branching model that organizes the development process into structured branches, making it easier to manage releases and development. The main branches include main, develop, and several others for specific purposes.

Branch Types and Their Purpose:

1. main Branch:

   • Purpose: This branch contains production-ready code. It represents the latest stable release of the project.

   • Usage:

     • Always deployable and stable.

     • Merges from release branches and hotfix branches occur here.

     • Tag releases to mark significant versions.

2. develop Branch:

   • Purpose: Serves as the integration branch for features. It accumulates changes from feature branches before they are included in a release.

   • Usage:

     • Merges from feature branches.

     • Prepare release branches from develop.

     • Final testing and integration before releasing to main.

3. Feature Branches:

   • Naming Convention: feature/branch-name

   • Purpose: Develop new features or improvements.

   • Creation:

       git checkout -b feature/new-feature develop
     

   • Merging:

       git checkout develop
       git merge feature/new-feature
     

   • Deletion (after merge):

       git branch -d feature/new-feature
     

4. Release Branches:

   • Naming Convention: release/x.y.z

   • Purpose: Prepare for a new release, allowing for final tweaks and testing.

   • Creation:

       git checkout -b release/1.0.0 develop
     

   • Merging:

       git checkout main
       git merge release/1.0.0
       git tag -a v1.0.0 -m "Release version 1.0.0"
       git push origin main --tags
     

   • Post-release Merge:

       git checkout develop
       git merge release/1.0.0
     

   • Deletion (after merge):

       git branch -d release/1.0.0
     

5. Hotfix Branches:

   • Naming Convention: hotfix/x.y.z

   • Purpose: Address urgent issues that need to be resolved in the production environment.

   • Creation:

       git checkout -b hotfix/1.0.1 main
     

   • Merging:

       git checkout main
       git merge hotfix/1.0.1
       git tag -a v1.0.1 -m "Hotfix version 1.0.1"
       git push origin main --tags
     
       git checkout develop
       git merge hotfix/1.0.1
     

   • Deletion (after merge):

       git branch -d hotfix/1.0.1
