# What it does
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 `[AIV]{version}[/AIV]`
- inject version from package.json into any place in CSS/JS file by special tag `[AIV]{version}[/AIV]`
- auto increase package.json version by --env.major, --env.minor, --env.patch passed into webpack
# How to use
It's easy to set it up, all you need is:
* use WebpackAutoInject in webpack plugins
* pass config as a parameter, or leave it blank as all options are "on" by default.
### Example ( in webpack.conf.js )
```js
var WebpackAutoInject = require('webpack-auto-inject-version');
...
module.exports = {
...
plugins: [
new WebpackAutoInject({
// options
// example:
components: {
AutoIncreaseVersion: false
}
})
]
}
```
# Available options
### components.AutoIncreaseVersion
Auto increase package.json number. <br>
This option requires extra argument to be sent to webpack build. <br>
It happens before anything else to make sure that your new version is injected into your files.<br>
Arguments: --env.major --env.minor --env.patch<br><br>
Example for package.json run type, npm run start => ( 1.2.10 to 2.0.0 )
```json
"version" : "1.2.10",
"scripts": {
"start": "webpack --env.major"
}
```
Default: true
### components.InjectByTag
Inject version number into your file<br>
Version will replace the <{version}> tag.<br>
```html
<span>My awesome project | [AIV]{version}[/AIV]</span>
```
```js
var version = '[AIV]{version}[/AIV]';
```
Default: true
### components.InjectAsComment
This will inject your version as a comment into any css,js,html file.<br>
Default: true
# Examples of the plugin outputs
AIV can inject version number for all your bundle files (css,js,html).<br><br>
```js
// [AIV] Build version: 1.0.10
/******/ (function(modules) { // webpackBootstrap
/******/ // The module cache
/******/ var installedModules = {};
```
<br><br>
Example html:
```html
<!-- [AIV] Build version: 1.0.10 -->
<!DOCTYPE html>
<html lang="en">
```
