# 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.
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: --env.major --env.minor --env.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 --env.major"
}
```
Default: true
### components.InjectByTag
Inject version number into your file
Version will replace the <{version}> tag.
```html
My awesome project | [AIV]{version}[/AIV]
```
```js
var version = '[AIV]{version}[/AIV]';
```
Default: true
### components.InjectAsComment
This will inject your version as a comment into any css,js,html file.
Default: true
# Examples of the plugin outputs
AIV can inject version number for all your bundle files (css,js,html).
```js
// [AIV] Build version: 1.0.10
/******/ (function(modules) { // webpackBootstrap
/******/ // The module cache
/******/ var installedModules = {};
```
Example html:
```html
```
