    Archetype: Electrode React Isomorphic Universal App

    NPM version Build Status Dependency Status

    A Walmart Labs flavored React Universal App archetype.


    What is this for?

    This "app archetype" provides for common patterns across all app projects so that each app project can standardize on common development behavior and patterns. Its essentially pre-made patterns for build scripts.

    How do I start developing in my application project after installing?

    # This runs both the node server and webpack (in hot mode) 
    $ gulp hot
    # Also try `dev` mode when running off battery power and you wish to maximize battery life. 
    $ gulp dev

    What is hot mode?

    Hot mode enables Hot module reloading(HMR), it is where webpack transpiles your javascript and css code and continues to watch for any changes, and, builds and loads only the code that has changed on disk. It allows you to develop without re-loading your browser page as the changes will be automagically piped in.

    How do I run my application tests?

    # This will run test eslint and your spec tests 
    $ gulp check

    How do I run my application tests without going through eslint (i.e., while I'm developing)?

    # This will run only your spec tests 
    $ gulp test-dev

    Why can't my test and code changes get automatically run with the tests? Why do the tests take so long to start?

    # This will start a webpack-dev-server to hot watch your code and also start a karma test browser that auto-reruns when specs or client code changes. 
    $ gulp test-watch-all

    How do I use and/or view the final build files without minifying/uglifying but also with sourcemaps?

    # This will build your code and save to disk, and then start a node server (without using webpack-dev-server). 
    $ gulp dev-static

    Is there anything else that might be nice for my development?

    # This will start the node server in debug mode so that you can place breakpoints, "debugger" statements, or use `node-inspector`. 
    $ gulp debug

    How do I view my test result in the browser?

    Run either of the below commands before opening the link.

    gulp server-test
    gulp dev # (OR) (which includes `server-test`)
    gulp hot # (OR) (which includes `server-test`)

    This will serve the static assets for test.html

    open test.html to view test result.

    How do I generate a manifest.json and a service-worker file?

    First we need to add a sw-config.js file under the app's config folder.

    This file contains two sections:

    1. Manifest
    manifest: {
    logo: "./images/icon.png",
    title: "Electrode Progressive App",
    short_name: "EPA",
    start_url: "/"

    Manifest gives you control over how your web app is installed on user's home screen with short_name, title and logo properties. You can also specify a starting path to launch your app with start_url property. Manifest defines how your app appears to the user and more importantly how they can launch it.

    2. Cache
    cache: {
      runtimeCaching: [{
        handler: "fastest",
        urlPattern: /\/home$/
      }, {
        handler: "networkFirst",
        urlPattern: /getBeer/
      staticFileGlobs: ['dist/**/*']

    Seamlessly cache your static assets or run time routes or cache them together! Precache your static assets generated by webpack using the staticFileGlobs property. Or use the runtimeCaching property to cache specific react routes in from your routes.jsx.

    Once this file is added, running

    gulp build

    will generate a manifest.json file inside of dist/js/icons-[hash] and a service worker file dist/sw.js.

    Service Worker file is generated during the build step and it will precache all the static resources as per the configuration in sw-config.js. Using AboveTheFoldOnlyServerRender you can avoid caching of certain components inside the crucial pages of your app to make your App shell even lighter.

    <AboveTheFoldOnlyServerRender skip={true}>
        this will not be a part of your app shell

    We use [gulp] as a task invoker. You should install it globally.

    $ sudo npm install -g gulp
    run the following in your project
    $ npm install --save-dev gulp electrode-archetype-react-app electrode-archetype-react-app-dev
    Add a gulpfile.js

    The gulpfile.js should contain the following and be located in the root of your project

    Add a .babelrc to your project

    The .babelrc needs to extend the archetype's babel configuration in order to apply the presents (ES2015, React) and the plugins like i18n. If your project needs additional Babel settings (like using stage 0 features) you can add them to this file. See the Babel docs for more information.

      "extends": "./node_modules/electrode-archetype-react-app/config/babel/.babelrc"
    Use babel-core/register in your server entry point

    If you don't have a build step for your server code, then you must transpile on the fly using babel-register. For performance reasons, we recommend whitelisting the react module to be transpiled as well, so that the transform-node-env-inline plugin gets applied to the React codebase:

      ignore: /node_modules\/(?!react\/)/
    Use the cssModuleHook in your server entry point for isomorphic CSS modules

    If you want to enable isomorphic css modules, the server needs to know how to import css files and generate unique class names. The archetype can handle this for you using the supports module. In your server entry point:

    var supports = require("electrode-archetype-react-app/supports");
    Define client entry points

    By default, the archetype uses client/app.js or client/app.jsx as a client entry point. Alternatively, you can define multiple entry points for your application, so the Webpack will create bundles for each app entry point. To do that, place entry.config.js module into your app's client directory:

    Here is an example of entry.config.js:

    module.exports = {
      "web": "./app-web.js",
      "ios": "./app-ios.js",
      "android": "./app-android.js"


    Run gulp to see list of tasks.
