keep-a-changelog

Node package to parse and generate changelogs following the keepachangelog format.

Install

You can install it from the npm repository using npm/yarn:

npm install keep-a-changelog

Usage

const { parser } = require('keep-a-changelog');
const fs = require('fs');

//Parse a changelog file
const changelog = parser(fs.readFileSync('CHANGELOG.md', 'UTF-8'));

//Generate the new changelog string
console.log(changelog.toString());

Create a new changelog

const { Changelog, Release } = require('keep-a-changelog');

const changelog = new Changelog('My project')
    .addRelease(
        new Release('0.1.0', '2017-12-06')
            .added('New awesome feature')
            .added('New other awesome feature')
            .fixed('Bug #3')
            .removed('Drop support for X')
    )
    .addRelease(
        new Release('0.2.0', '2017-12-09')
            .security('Fixed security vulnerability')
            .deprecated('Feature X is deprecated')
    );

console.log(changelog.toString());

Custom tag names

By default, the tag names are v + version number. For example, the tag for the version 2.4.9 is v2.4.9. To change this behavior, set a new tagNameBuilder:

const changelog = new Changelog();
changelog.tagNameBuilder = release => `version-${release.version}`;

Cli

This library provides the changelog command to normalize the changelog format. It reads the CHANGELOG.md file and override it with the new format:

changelog

To use other file name:

changelog --file=History.md

To generate an empty new CHANGELOG.md file:

changelog --init

Available options:

Option	Description
`--file`	The markdown file of the changelog. The default value is `CHANGELOG.md`.
`--url`	The base url used to build the diff urls of the different releases. It is taken from the existing diff urls in the markdown. If no urls are found, try to catch it using the url of the git remote repository.
`--https`	Set to false to use `http` instead `https` in the url (`--https=false`).
`--init`	Init a new empty changelog file.
