Dev stack and starter kit for React universal apps. One stack for browser, server, mobile. Forget about evil frameworks, use laser focused libraries and design patterns instead.

You don't have to start with everything. Este is perfect even for plain static pages. You can gracefully add any platform later. Este mission is simple: Help startups to deliver minimal valuable product asap with the state of the art real-time universal app stack.

  • Truly universal architecture
    • code shared across platforms (browser, server, native mobile)
    • server side rendering or server-less pre-rendering to HTML files
    • universal routing
    • universal internationalization (with runtime language switching)
    • universal crash reporting (via Sentry)
    • universal data fetching
    • universal forms with universal validation (universal ftw, yeah)
  • Well tuned dev stack (OS X, Linux, Windows)
  • Immutable app state
  • Stateless functional UI components with JavaScript styles
  • Flowtype
  • Vanilla hot reloading makes everything hot reloadable
  • Firebase integration (
    • useful predefined Redux actions
    • email and facebook login
    • declarative queryFirebase higher order component for Firebase imperative API
    • user presence
  • Este is monorepo, read why.



  • node.js Node 6 with NPM 3 is required.
  • gulp npm install -g gulp
  • git git cmd tool is required


If you are using different node versions on your machine, use nvm to manage them.

Create App

git clone --depth=1 este-app
cd este-app
npm install

Start Development

  • run gulp
  • point your browser to localhost:3000
  • build something beautiful

React Native: Getting Started

Dev Tasks

  • gulp run web app in development mode
  • gulp ios run iOS app in development mode
  • gulp android run Android app in development mode
  • gulp -p run web app in production mode
  • gulp -f run web app in development mode, but only browser source rebuilds on file changes
  • gulp ava run ava unit tests
  • gulp ava-watch continuous test running for TDD
  • gulp eslint eslint
  • gulp eslint --fix fix fixable eslint issues
  • gulp messages-extract extract messages for translation
  • gulp messages-check check missing and unused translations
  • gulp messages-clear remove unused translations
  • gulp favicon create universal favicon

Production Tasks

  • gulp build -p build app for production
  • npm test run all checks and tests
  • node src/server start app, remember to set NODE_ENV and SERVER_URL
  • gulp to-html render app to HTML for static hosting like Firebase
  • gulp deploy-heroku deploy Heroku app
  • gulp deploy-firebase deploy Firebase app
  • gulp deploy-firebase-database deploy Firebase database only

Customize Este App

  • set name in package.json
  • set locales, firebaseUrl, sentryUrl, etc. in src/server/config.js
  • remove unused locale-data from src/browser/index.js
  • change src/common/app/favicons/original/favicon.png, then gulp favicon and gulp -p
  • remove unused reducers from src/common/configureReducer.js
  • delete unused app features, todos for example: src/{platform}/todos
  • modify your FB app_id e.g. for iOS


  • install
  • go to Nuclide settings, enable "Use the Flow binary included in each project"


For absolute beginners, see: react-howto.

So you've decided to give this web stack a chance, but where is the documentation? Code is documentation in itself as it illustrates various patterns, but to start with you should educate yourself on React.js and Redux. You should learn ES6 to refresh your knowledge about "new" JavaScript practices and syntax. This stack uses immutable.js and class-less design for a good reason. Express.js is used on the Node.js based server. The application architecture is universal so we can share code between the browser, server, & mobile platform easily. Congrats, you're Este.js expert level 1 now :-)



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.

Tips and Tricks

  • Open developer console to check current app state.
  • With functional programming (SOLID: the next step is Functional), we don't need DI containers. We can use plain old Pure DI. Check injectMiddleware in configureMiddleware.
  • Learn immutable.js, for example Seq. Handy even for native arrays and objects. For example, get object values: Seq(RoomType).toSet().toJS()
  • Recommended editor is Atom. Check settings.


Why do I get EACCES error during npm install?

This indicates that you do not have permission to write to the directories that npm uses to store packages and commands. One possible solution is to change the permission to npm's default directory.

  1. Find the path to npm's directory: npm config get prefix For many systems, this will be /usr/local
  2. Change the owner of npm's directory's to the effective name of the current user sudo chown -R `whoami` <directory>

Does Hapi/SailJS/Restify/Rails work with Este? Do you have any example app for this framework?

Yes it does. Este is agnostic of what you use in your backend and is completely decoupled from the API. It uses an Express app for server-side rendering, but you can use anything for your API. The only benefit that an Express API has is that it can simply be called with a use() statement by the main app, just like any other middleware.

Is it possible use XYZ library with Este?

Yes. Este tries to make as few assumptions about your stack as possible. This is not a framework, nothing prevents you from picking the bits you're interested in.

How is React Native used in this project?

In the same way as any other React Native project is created via react-native init AwesomeProject. But thanks to the universal application design we can easily share modules across platforms.
