  • The gap between mocking up wireframes of semantically formed ideas and implementing them has never been closer.
  • ChatServer.prototype.connect = function (username) { var self = this; this.setUsername(username); this.socket = io(); this.socket.on(‘connect’, function () { self.socket.on(events.CONNECT, function (userId) { if (userId === self.getUsername()) { return; } self._connectTo(userId); self.emit(events.CONNECT, userId); console.log(‘User connected’, userId); });
  • JSX is similar to a mix of XML and HTML. You use JSX within React code to easily create components for your apps.
  • Heroku also creates a git repo for this app.
  • We will start the app from the ground up to give you a good feel of how to create a React application.

You might not need React Router — Medium

  • I’m familiar with, there is no need in using nested routes as it’s done in RR.
  • /history’; function render(location) { /* Render React app, read on */ } render(history.getCurrentLocation()); // render the current URL history.listen(render); // render subsequent URLs
  • /routes’; const container = document.getElementById(‘root’); function renderComponent(component) { ReactDOM.render(component, container); } function render(location) { router.resolve(routes, location) .then(renderComponent) .catch(error => router.resolve(routes, { …
  • import React from ‘react’; import history from ‘.
  • The router itself can be written as a pair of two functions – matchURI(), an internal (private) function that helps to compare a parametrized path string with the actual URL; and resolve() function that traverses the list of routes, finds the route that matches to the given location, executes route handler function and returns result to the caller.

Application Environment Configuration with webpack — Matt McLaugh

  • /src/config/dev.js to config, you can call import config from ‘config’ throughout your application.
  • ‘s an example of the development webpack config from my front-end-template repo
  • Webpack is very robust, and we can achieve environment configuration with no extra plugins.
  • With the method you don’t have to rely on global variables, you can comment your config files (they’re just javascript) and change the alias location of config for each webpack environment configuration file.
  • When configuring webpack, I prefer to keep separate config files for each environment.

Recycling Rows For High Performance React Native List Views — Medium

Recycling rows for high performance #ReactJS Native list views:

  • As the user scrolls, rows that are no longer visible will be freed, and new rows that become visible will be allocated.
  • In order to recycle rows properly, we must always be aware of the current scroll offset since rows must be recycled as soon as the user scrolls.
  • Every contact row probably looks the same and has the same structure.
  • If your use-case falls under the second use-case: High variation between rows and a smaller data-source – you should probably stick with the stock ListView implementation.
  • If a cell can be recycled (from a row gone off-screen), this method will return the recycled cell.

Building the World Bank data site as a fast-loading, single-page app with code splitting

Building the World Bank data site as a fast loading, single-page app:  #ReactJS

  • We can define our split points in the lazy load code.
  • Building the World Bank data site as a fast-loading, single-page app with code splitting
  • We can create chunks in two steps: define split points in routes and use react router’s match in both client side and server side.
  • We can create on demand load chunks by define split point in our code.
  • React router allows us to use lazy load route-related code, also called dynamic routing.
