npm-install-loader

Webpack loader to automatically npm install & save dependencies.

Why?

It sucks to Ctrl-C your build script & server just to install a dependency you didn't know you needed until now.

Instead, use require or import how you normally would and npm install will happen automatically install missing dependencies between reloads.

Usage

In your webpack.config.js:

module: {
  postLoaders: [
    {
      exclude: /node_modules/,
      loader: "npm-install-loader",
      test: /\.js$/,
    },
  ],
}

This will ensure that any other loaders (e.g. eslint-loader, babel-loader, etc.) have completed.

Saving

This loader simply runs npm install [modules].

I recommend creating an .npmrc file in the root of your project with:

save=true

This will automatically save any dependencies anytime you run npm install (no need to pass --save).

Alternatively, you can provide CLI arguments that get added directly to npm install:

postLoaders: [
  {
    exclude: /node_modules/,
    loader: "npm-install-loader",
    query: {
      cli: {
        registry: "..."   // --registry='...'
        save: true,       // --save
        saveExact: true,  // --save-exact
      },
    },
    test: /\.js$/,
  },
],
