# Auto inject version - Webpack plugin
## Add version to bundle automatically
## What
Auto Inject Version (AIV) can:
- inject version from package.json into every bundle file as a comment ( at the top )
- inject version from package.json into any place in your HTML by special tag <{version}>
- inject version from package.json into any place in CSS/JS file by special tag <{version}>
- auto increase version by --major, --minor, --patch and then inject as chosen
## Desc
AIV can inject version number for all your bundle files (css,js,html).
Example js:
```js
// [AIV] Build version: 1.0.10
/******/ (function(modules) { // webpackBootstrap
/******/ // The module cache
/******/ var installedModules = {};
```
Example html:
```html
```
AIV can also auto inject your version number into html by using special code ( <{version}> ).
Example:
```html
My awesome project | <{version}>
```
## Install
```console
$ npm install webpack-auto-inject-version --save-dev
```
## Usage
```js
var WebpackAutoInject = require('webpack-auto-inject-version');
module.exports = {
plugins: [
new WebpackAutoInject(options)
]
}
```
## Options
### autoIncrease
Auto increase package.json number.
This option requires extra argument to be sent to webpack build.
It happens before anything else to make sure that your new version is injected into your files.
Arguments: --major --minor --patch
Example for package.json run type, npm run start => ( 1.2.10 to 2.0.0 )
```json
"version" : "1.2.10",
"scripts": {
"start": "webpack --major"
}
```
Default: true
### injectByTag
Inject version number into your file
Version will replace the <{version}> tag.
```html
My awesome project | <{version}>
```
```js
var version = '<{version}>';
```
Default: true
### injectByTagFileRegex
Regex against file name. If match, injectByTag will try to find version tag and replace it.
Only html files: /^(.){1,}\.html$/
Only js files: ^(.){1,}\.js$
Any file: (.){1,}
Default: /^index\.html$/
### injectAsComment
This will inject your version as a comment into any css,js,html file.
