The most complete React/Flux dev stack and starter kit for isomorphic functional web apps. Este.js acts as a next-gen to-go everything-but-the-kitchen-sink boilerplate.

The most complete React/Flux dev stack and starter kit for isomorphic functional web apps. Forget about evil frameworks, learn laser focused libraries and patterns instead.

UPDATE: I'm in San Francisco right now. Feel free to ask for Este.js training or consulting. Write me.

Forget about PHP/Ruby/Angular/Backbone whatever client or server only framework. Also, we don't need yet another Flux library, vanilla Flux is good enough. This dev stack is web dev panacea, at least for me :-)


  • Isomorphic pure React with server side rendering on expressjs backend.
  • Stateless vanilla Flux with atomic global immutable app state like Om via immutable.js for super fast rendering and sane state management.
  • Functional design. Class is a leaky abstraction for "business model".
  • ECMAScript 2015+ with the best transpiler JSX and Flowtype syntax supported. Sourcemaps are enabled by default.
  • Well tuned webpack dev stack with handy notifier.
  • CSS livereload.
  • Hot module reload for React components and Flux actions and stores..
  • Karma as the test runner, mocha as test framework, and Chai as BDD / TDD assertion library.
  • Testing stack configured for TDD - test driven development.
  • Shallow rendering for testing React components without DOM.
  • eslint ES6 linting with React JSX support. (Sublime Text 3 integration)
  • Localization via, stale browsers supported as well.
  • react-router for routing on client and server side.
  • Simple yet powerfull sync/async validation based on famous chriso/validator.js
  • Login and Signup, requireAuth higher order component to protect access to specific pages.
  • LESS, SASS, Stylus, or plain CSS with autoprefixer.
  • Easy undo/redo and load/save for app state.


Install node.js. Then install gulp.js.

npm install -g gulp


Use this if you are using JEST or another library, which has to be compiled.

  • Install Python - Install version 2.7 of Python and add it to your path or/and create a PYTHONPATH environment variable.
  • Install Visual Studio (Express Edition is fine) - We will need this for some of modules that are compiled when we are installing Este. Download VS Express, get one of the versions that has C++ - Express 2013 for Windows Desktop for example.
  • Set Visual Studio Version Flags - We need to tell node-gyp (something that is used for compiling addons) what version of Visual Studio we want to compile with. You can do this either through an environment variable GYP_MSVS_VERSION. If you are using Express, you have to say GYP_MSVS_VERSION=2013e.

Create App

git clone este-app
cd este-app
npm install

Start Development

  • run gulp
  • point your browser to localhost:8000
  • build something beautiful

Dev Tasks

  • gulp run app in development mode
  • gulp -p run app in production mode
  • gulp test

CI Tasks

  • npm start just run app, remember to set NODE_ENV=production and others environment variables.
  • npm postinstall just alias for gulp build --production, useful for Heroku.
  • npm test just alias for gulp test


So you decided to give a chance to this web stack, but where is documentation? Code is documentation itself as it illustrates various patterns, but for start you should read something about React.js. Then you should learn what is the Flux application architecture. Now refresh you JavaScript knowledge about "new" JavaScript - learn ES6. This stack uses immutable.js and class-less design for a good reason. Check this nice short video, wouldn't be possible with classic OOP classes everywhere approach. Functional programming is a next (current) big thing, read why. Express.js is used on the Node.js based server. Application is isomorphic, so we can share code between client and server easily. Congrats, now you're Este.js expert level 1 :-)


Tips and Tricks

  • To check app state, press ctrl+shift+s, and then open console.
  • To check app render time, open console, and write este.measureRender = true.
  • With global app state, we don't need IoC container so badly - SOLID: the next step is Functional. Still DI is relevant for some cases and then use Pure DI.
  • Use const by default, let if you have to rebind a variable.
  • Learn and use immutable Seq. Very handy for native arrays and objects. For example, get object values: Seq(RoomType).toSet().toJS()
  • Even though we can use import {canUseDOM} from 'react/lib/ExecutionEnvironment' to detect browser/server, don't do it since it's runtime value. Use webpack DefinePlugin to set process.env.IS_BROWSER rather, because compilation removes dead code.
  • How to use Closure Tools, gist
  • Recommended editor is sublimetext, or (tips).



  • Este.js dev stack should work on OSX, Linux, and Windows. Feel free to report any issue.
  • As a rule of thumb, Este.js supports all evergreen browsers plus last two pieces of IE.
