bumpver-webpack-plugin

A webpack plugin to bump the major, minor, or patch number for a build.

Install

npm install bumpver-webpack-plugin --save-dev

or

yarn add bumpver-webpack-plugin --dev

Usage

Increments patch number by default, but you can specify either major, minor, or patch.

Arguments:

• files (required): one or more file names containing "version" to increment
• level (optional): semver level - 'major', 'minor', or 'patch'

To use default settings and increment patch for every build...

const BumpVerPlugin = require('bumpver-webpack-plugin');

module.exports = {
    plugins: [
        new BumpVerPlugin({
            files: ['package.json']
        })
    ]
}

To specify semver level ("major", "minor", or "patch") for every build...

const BumpVerPlugin = require('bumpver-webpack-plugin');

module.exports = {
    plugins: [
        new BumpVerPlugin({
            files: ['package.json'],
            level: 'patch'
        })
    ]
}

To pass a semver level to your webpack config, set variable via env parameter like this...

const BumpVerPlugin = require('bumpver-webpack-plugin');

module.exports = (env) => {
    return {
        plugins: [
            new BumpVerPlugin({
                files: ['package.json', 'manifest.json'],
                level: env.VERSION_LEVEL
            })
        ]
    }
}

Then, in your call to webpack add a variable to env containing the semver level to increment...

"scripts": {
    "build-major": "webpack --env.VERSION_LEVEL=major",
    "build-minor": "webpack --env.VERSION_LEVEL=minor",
    "build": "webpack"
}

As per the semver spec, when you increment minor the patch value will be reset to 0. When you increment major both the minor and patch will be reset to 0.

Plugin based on original bump-webpack-plugin by johnagan. Expanded functionality to include semver level.
