Converter - React

A simple app written using React and CommonJS, built with Webpack. Based on full-stack-testing.formidablelabs.com/app/ from our "Full. Stack. Testing" training project.

Overview

The converter app has a simple Express-based REST backend that serves string conversions. The frontend app is a React app, crafted with the following:

• ES6 via Babel for client code.
• Components from react-bootstrap
• Redux for data layer.
• isomorphic-fetch for AJAX requests.
• Server-side rendering and SPA bootstrap.

See the app hard at work!

• 127.0.0.1:3000/: Server-side bootstrap, then client-side.
• 127.0.0.1:3000/?__mode=noss: Pure client-side.
• 127.0.0.1:3000/?__mode=nojs: Pure server-side.

Notes

Size

To test out how optimized the build is, here are some useful curl commands:

# Run production build
$ npm run build

# Minified size
$ wc -c dist/js/*.js
  286748 dist/js/bundle.d3749f460563cd1b0884.js

# Minified gzipped size
$ gzip -c dist/js/*.js | wc -c
   77748

Development

For a deeper dive, see: DEVELOPMENT

Dev Mode

Install, setup.

$ npm install           # Install dependencies
$ npm run install-dev   # Install dev. environment (selenium, etc.).

Run the watchers, dev and source maps servers for the real production build:

$ npm run prod

Run the watchers and the Webpack dev server:

$ npm run dev

Run the watchers and the Webpack dev server w/ React hot loader:

$ npm run hot

Ports various servers run on:

• 2992: Webpack dev server for dev. server.
• 3000: Development application server.
• 3001: Sourcemaps static server / test (in-browser) server.
• 3010: Webpack dev server for ephemeral client Karma tests run one-off with full build.
• 3020: Ephemeral app server for REST server tests. Override via TEST_REST_PORT environment variable.
• 3030: Ephemeral app server for functional tests. Override via TEST_FUNC_PORT environment variable.
• 3031: Webpack dev server for ephemeral functional tests run one-off with full build. Override via TEST_FUNC_WDS_PORT environment variable.

URLS to test things out:

• 127.0.0.1:3000/: Server-side bootstrap, then JS.
• 127.0.0.1:3000/?__mode=noss: Pure JS.
• 127.0.0.1:3000/?__mode=nojs: Pure server-side. Note that while some links may work (e.g. clicking on a note title in list), many things do not since there are absolutely no JS libraries. This is intended to just be a small demo of SEO / "crawlable" content. This mode is incompatible with the React hot loader mode because in hot mode JS is used to load CSS. If you want to run a development server while using nojs, use npm run dev.

Bootstrapped Data

As a development helper, we allow a querystring injection of data to bootstrap the application off of. Normally, you wouldn't allow users to add this, and instead would choose how to best bootstrap your app.

• 127.0.0.1:3000/?__bootstrap=camel:hello%20there: Server-side data bootstrapped into the application + render.
• 127.0.0.1:3000/?__mode=noss&__bootstrap=camel:hello%20there: Pure client-render, but bootstrap the store off types and values and initiate async fetch to backend for data automatically.
• 127.0.0.1:3000/?__mode=nojs&__bootstrap=camel:hello%20there: Pure server-side render with no JS. Should fully render the inputs and converted values in static HTML.

Production

Install, setup.

$ npm install --production
$ npm run build

Run the server.

$ NODE_ENV=production node server/index.js
