Automate Versioning and CHANGELOG Generation

Overview

Assume we have a service/app repository. We want to automate the versioning and CHANGELOG generation. How to achieve this? In this article, I will explain how to automate versioning and CHANGELOG generation using commit-and-tag-version.

Prerequisites

• commit-and-tag-version app
• Git Repository

How to

Installing commit-and-tag-version.

npm i -g commit-and-tag-version

Assume you already have git repository.

1. Create configuration file .versionrc

   // .versionrc
   {
     "packageFiles": [
       {
         "filename": "version.json",
         "type": "json"
       }
     ],
     "bumpFiles": [
       {
         "filename": "version.json",
         "type": "json"
       }
     ]
   }

2. Create version.json file.

   // version.json
   {
       "version": "1.0.0"
   }

3. Run first release

   commit-and-tag-version --first-release

4. Test create commit

   git commit --allow-empty -m "feat: add feature A"

   commit-and-tag-version
