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.

Simple config example ( in webpack.conf.js )

var WebpackAutoInject = require('webpack-auto-inject-version');
...
module.exports = {
    ...
    plugins: [
        new WebpackAutoInject({
            // options
            // example:
            components: {
                AutoIncreaseVersion: false
            }
        })
    ]
}

Full config example ( in webpack.conf.js )

module.exports = {
    ...
    plugins: [
      new WebpackAutoInject({
        // specify the name of the tag in the outputed files eg
        // bundle.js: [SHORT]  Version: 0.13.36 ...
        SHORT: 'CUSTOM',
        SILENT: false,
        PACKAGE_JSON_PATH: './package.json',
        PACKAGE_JSON_INDENT: 4,
        components: {
          AutoIncreaseVersion: true,
          InjectAsComment: true,
          InjectByTag: true
        },
        componentsOptions: {
          AutoIncreaseVersion: {
            runInWatchMode: false // it will increase version with every single build!
          },
          InjectAsComment: {
            tag: 'Version: {version} - {date}',
            dateFormat: 'h:MM:ss TT', // change timezone: `UTC:h:MM:ss` or `GMT:h:MM:ss`
            multiLineCommentType: false, // use `/** */` instead of `//` as comment block
          },
          InjectByTag: {
            fileRegex: /\.+/,
            // regexp to find [AIV] tag inside html, if you tag contains unallowed characters you can adjust the regex
            // but also you can change [AIV] tag to anything you want
            AIVTagRegexp: /(\[AIV])(([a-zA-Z{} ,:;!()_@\-"'\\\/])+)(\[\/AIV])/g,
            dateFormat: 'h:MM:ss TT'
          }
        },
        LOGS_TEXT: {
          AIS_START: 'DEMO AIV started'
        }
      })
    ]
}

Inject by tag example

<body>
  <span>
    [AIV]{version}[/AIV]
  </span>
  <span>
    [AIV]{date}[/AIV]
  </span>
  <span>
    [AIV]{version}_{date}[/AIV]
  </span>
  <span>
    [AIV]V:{version} Date:{date}[/AIV]
  </span>
  <span>
    [AIV]Version {version} , {date}[/AIV]
  </span>
</body>

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 )

 "version" : "1.2.10",
 "scripts": {
    "start": "webpack --env.major"
 }

To enable watch mode:

  plugins: [
    new WebpackAutoInject({
      ...
      components: {
        AutoIncreaseVersion: true,
        ...
      },
      componentsOptions: {
        AutoIncreaseVersion: {
          runInWatchMode: false // it will increase version with every single build!
        }
      }
    })
  ]

Default: true

components.InjectByTag

Inject version number into your file
Version will replace the <{version}> tag.

<span>My awesome project | [AIV]{version}[/AIV]</span>
var version = '[AIV]{version}[/AIV]';

Default: true

components.InjectAsComment

This will inject your version as a comment into any css,js,html file.
You can change what is injected into the file by changing componentsOptions.InjectAsComment.tag. Currently only 2 tags are supported:

  • {version}
  • {date} ( current date ) Example:
  ...
  plugins: [
    ...
    new WebpackAutoInject({
      PACKAGE_JSON_PATH: './package.json',
      components: {
        ...
        InjectAsComment: true
      },
      componentsOptions: {
        ...
        InjectAsComment: {
          tag: 'Build version: {version} - {date}', // default
          dateFormat: 'dddd, mmmm dS, yyyy, h:MM:ss TT', // default
          multiLineCommentType: false, // default
        }
    })
  ]

Default: true

Output-examples

AIV can inject version number for all your bundle files (css,js,html).

// [AIV] Build version: 1.0.10
/******/ (function(modules) { // webpackBootstrap
/******/ 	// The module cache
/******/ 	var installedModules = {};



Example html:

<!-- [AIV] Build version: 1.0.10 -->
<!DOCTYPE html>
<html lang="en">

How to use with other webpack plugins

Webpack plugins order matters! Always try to put WebpackAutoInject as a first webpack plugin.

compression-webpack-plugin

  plugins: [
    new WebpackAutoInject(),
    new CompressionPlugin(),
  ]

uglifyjs-webpack-plugin

  plugins: [
    new WebpackAutoInject(),
    new UglifyJsPlugin(),
  ]

webpack.optimize.UglifyJsPlugin

If the order won't be enough, you can always add ignore to the uglifyJsPlugin to prevent stripping out AIV comments eg:

  new webpack.optimize.UglifyJsPlugin({
    ...
    output: {
      // prevent version info to be removed from bundle.js
      comments: /\[AIV\]/,
    },
    ...
  });
