How to determine the installed webpack version

Version Installed:

Using webpack CLI: (--version, -v Show version number [boolean])

webpack --version

or:

webpack -v

Using npm list command:

npm list webpack

Results in name@version-range:

<projectName>@<projectVersion> /path/to/project└── webpack@<version-range>

Using yarn list command:

yarn list webpack

How to do it programmatically?

Webpack 2 introduced Configuration Types.

Instead of exporting a configuration object, you may return a function which accepts an environment as argument. When running webpack, you may specify build environment keys via --env, such as --env.production or --env.platform=web.

We will use a build environment key called --env.version.

webpack --env.version $(webpack --version)

or:

webpack --env.version $(webpack -v)

For this to work we will need to do two things:

Change our webpack.config.js file and use DefinePlugin.

The DefinePlugin allows you to create global constants which can be configured at compile time.

-module.exports = {+module.exports = function(env) {+  return {    plugins: [      new webpack.DefinePlugin({+        WEBPACK_VERSION: JSON.stringify(env.version) //<version-range>      })    ]+  };};

Now we can access the global constant like so:

console.log(WEBPACK_VERSION);

Latest version available:

Using npm view command will return the latest version available on the registry:

npm view [<@scope>/]<name>[@<version>] [<field>[.<subfield>]...]

For webpack use:

npm view webpack version

For those who are using yarn

yarn list webpack will do the trick

$ yarn list webpackyarn list v0.27.5└─ webpack@2.6.1Done in 1.24s.

Just another way not mentioned yet:

If you installed it locally to a project then open up the node_modules folder and check your webpack module.

$cd /node_modules/webpack/package.json

Open the package.json file and look under version
