Install Webpack Plugin

Speed up development by automatically installing & saving dependencies with Webpack.

It is inefficient 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 installation will happen automatically to install & save missing dependencies while you work!

Installation

$ npm install --save-dev install-webpack-plugin

Usage

In your webpack.config.js:

plugins: [
  new InstallPlugin()
],

This is equivalent to:

plugins: [
  new InstallPlugin({
    dependencies: {
      peer: true,
    },
    packageManager: {
      type: this.getDefaultPackageManager(),
      options: {
        dev: false,
        quiet: false,
      },
    },
    prompt: true,
  });
],

Options

dependencies

Type: Object

Dependencies related options.

peer

Type: Boolean

Default: true

plugins: [
  new InstallPlugin({
    dependencies: {
      peer: true,
    }
  }),

packageManager

Package manager to use for installing dependencies.

plugins: [
  new InstallPlugin({
      packageManager: 'yarn'
    },
  }),
],

You can provide a Function to the packageManager to make it dynamic:

plugins: [
  new InstallPlugin({
    packageManager: function(module, path) {
      return [
        "babel-preset-react-hmre",
        "webpack-dev-middleware",
        "webpack-hot-middleware",
      ].indexOf(module) !== -1;
    },
  }),
],

          arguments: ['--ignore-scripts']
        }
      }
    },
  }),
],

        }
      }
    },
  }),
],

  new InstallPlugin({
      packageManager: {
