rollup-plugin-git-version

Rollup plugin to include the git rev in the version of package.json.

If you develop some software which is bundled with RollupJS, how many times have you done something like...?

import { version } from '../package.json';

And how many times have you wished that the current git branch and revision would be included in that version string?

If the answer is "more than zero", this RollupJS plugin is for you.

So if your package.json contains something like...

{
    version: "major.minor.patch"
    ...

Then, by using this plugin, when doing an import { version } from '../package.json';, version will have a value like "major.minor.patch+branchname.revision". This is in compliance with the semantic versioning standard about build metadata.

For example, if your package.json contains version: "1.2.3", then the value for the version value inside your rolled-up code will not be "1.2.3", but instead "1.2.3+master.890abc".

Installation

yarnpkg add --dev rollup-plugin-git-version

or

npm install --save-dev rollup-plugin-git-version

Usage

As with any other Rollup plugin, just add it to the plugins option in your RollupJS config:

// In rollup.config.js
import rollupGitVersion from 'rollup-plugin-git-version'
 
export default {
    entry: 'src/index.js',
    dest: 'dist/my-lib.js',
    plugins: [
        rollupGitVersion()
    ]
};

This plugin accepts the same options as @rollup/plugin-json.

If you use this plugin together with @rollup/plugin-json, please be aware that both plugins might try to fight for the file. You can use the exclude option of @rollup/plugin-json, e.g.:

// In rollup.config.js
import rollupGitVersion from 'rollup-plugin-git-version'
 
export default {
    entry: 'src/index.js',
    dest: 'dist/my-lib.js',
    plugins: [
        rollupGitVersion(),
        json({ exclude: 'package.json' })
    ]
};
