webpack:webpack by The Reactive Stack

Seamlessly integrate Webpack to improve Meteor build system
Compatible with Meteor 1.2 and 1.3

Why should you use Webpack?

  • No configuration required, you only need to add packages
  • Instant feedback when you change your files (not even a page refresh!)
  • Organize your assets with the code they belong
  • Faster page loading by splitting your code in multiple chunks

How can I get started?

You can learn how to use Webpack with Meteor by getting the free course on The Reactive Stack.

Many kickstart projects are also available so you can clone one that fits your needs.

Or you can start from scratch like this (this is a React / SASS example)

Start from scratch

meteor create test-project
cd test-project
npm init # Don't forget to set the entry files in package.json (see below)
meteor remove ecmascript
meteor add webpack:webpack
meteor add webpack:react
meteor add webpack:less
meteor add react-meteor-data
npm install

Entry files

Your entry files are defined within your package.json. The main is your server entry and the browser is your client entry.

  "name": "test-project",
  "private": true,
  "main": "server/entry.js",
  "browser": "client/entry.js"

Note: Make sure your entry point is NOT within an import folder or it would not work properly.


You can tweak your Webpack settings by using a webpack.json file in the root of your project.

  • css.modules (bool): Use local CSS by default (default to false)
  • hotMiddleware.reload (bool): Reload the page if hot reload doesn't work? (default to false)
  • devServer.host: The hostname the Webpack dev server will be using
  • disableDedupePlugin (bool): Disable the DedupePlugin (default to false)
  • disableOccurenceOrderPlugin (bool): Disable the OccurenceOrderPlugin (default to false)
  • postcss: Array of plugins to use
  • externals (object): Map external modules to a global variable
  • noParse (array of string): List the files you want Webpack to not parse (like huge libraries already built)
  • resolve (object): Configure modules or aliases to write shorter import statements
  • ...

See your package readme for more infos on the settings available.


Your .babelrc config will be automatically added to the configuration. You can add any presets, plugins or any babel config.

Webpack packages

You can visit the package documentation for more details on the settings you can use.


  • webpack:webpack: You need this package to use Webpack with Meteor
  • webpack:assets (automatically added): Bundle your file and image assets by importing them (.png, .jpg, .jpeg, .svg, .ttf, .woff, .woff2, .eot)


  • webpack:react: Use React and JSX with Webpack (.js and .jsx)
  • webpack:angular: Use Angular with Webpack (.js and .import.html)
  • webpack:vue: Use Vue.js with Webpack (.js and .vue)
  • webpack:blaze (coming soon): Use Blaze with Webpack (.js and .html)

NPM packages

You can use any NPM package by using the package.json file.

To add a new dependency, run at your project root: npm install --save module-name.


The production mode will be automatically detected and will optimize the bundle. The production is is activated when:

  • You run meteor --production
  • You bundle your project
  • You deploy with mup deploy or any other tool


If you need to run code in Meteor before the startup, you can do that if you name your file meteor.startup.js.

Calling FlowRouter.wait() is a great example of things you might want to do.
