Features

Front-end stack

Server-side rendering

  • Built-in Koa 2 web server, with async/await routing.
  • Full route-aware server-side rendering (SSR) of initial HTML.
  • Universal building - both browser + Node.js web server compile down to static files, for fast server re-spawning.
  • Per-request GraphQL store. Store state is dehydrated via SSR, and rehydrated automatically on the client.
  • MobX for app-wide flux/store state, for automatically re-rendering any React component that 'listens' to state. Fully typed state!
  • Full page React via built-in SSR component - every byte of your HTML is React.
  • SSR in both development and production, even with hot-code reload.

Real-time

  • Hot code reloading; zero refresh, real-time updates in development.
  • Development web server that automatically sends patches on code changes, and restarts the built-in Web server for SSR renders that reflect what you'd see in production.
  • WebSocket subscription query support for real-time data (just set WS_SUBSCRIPTIONS=1 in .env)

Code optimisation

  • Webpack v4, with tree shaking -- dead code paths are automatically eliminated.
  • Asynchronous code loading when import()'ing inside a function.
  • Automatic per-vendor chunk splitting/hashing, for aggressive caching (especially good behind a HTTP/2 proxy!)
  • Gzip/Brotli minification of static assets.
  • CSS code is combined, minified and optimised automatically - even if you use SASS, LESS and CSS together!

Styles

  • Emotion, for writing CSS styles inline and generating the minimal CSS required to properly render your components.
  • PostCSS v7 with next-gen CSS and automatic vendor prefixing when importing .css, .scss or .less files.
  • SASS and LESS support (also parsed through PostCSS.)
  • Automatic vendor prefixing - write modern CSS, and let the compiler take care of browser compatibility.
  • Mix and match SASS, LESS and regular CSS - without conflicts!
  • CSS modules - your classes are hashed automatically, to avoid namespace conflicts.
  • Compatible with Foundation, Bootstrap, Material UI and more. Simply configure via a .global.(css|scss|less) import to preserve class names.

Production-ready

  • Production bundling via npm run production, that generates optimised server and client code.
  • Static compression using the Gzip and Brotli algorithms for the serving of static assets as pre-compressed .gz and .br files (your entire app's main.js.bz - including all dependencies - goes from 346kb -> 89kb!)
  • Static bundling via npm run build:static. Don't need server-side rendering? No problem. Easily deploy a client-only SPA to any static web host (Netlify, etc.)

Developer support

  • Written in Typescript with full type support, out the box (all external @types/* packages installed)
  • Heavily documented code

Quick start

Grab and unpack the latest version, install all dependencies, and start a server:

wget -qO- https://github.com/leebenson/reactql/archive/4.5.1.tar.gz | tar xvz
cd reactql-4.5.1
npm i
npm start

Your development server is now running on http://localhost:3000

Building GraphQL HOCs

By default, your GraphQL schema lives in schema/schema.graphql

To create fully Typescript-typed Apollo React HOCs based on your schema, simply put the query in a .graphql anywhere inside the source folder, and run:

npm run gen:graphql

You can then import the query like we do in the HackerNews demo component:

// Query to get top stories from HackerNews
import { GetHackerNewsTopStoriesComponent } from "@/graphql";

And use it as follows:

<GetHackerNewsTopStoriesComponent>
    {({ data, loading, error }) => (...)}
</GetHackerNewsTopStoriesComponent>

To get access to the underlying gql-templated query (in case you need it for refetching, etc), in this case it'd be GetHackerNewsTopStoriesDocument.

See GraphQL Code Generator for more details on how it works.

You can also edit codegen.yml in the root to point to a remote schema, or change the file location.

Development mode

Development mode offers a few useful features:

  • Hot code reloading. Make a change anywhere in your code base (outside of the Webpack config), and changes will be pushed down the browser automatically - without page reloads. This happens for React, Emotion, SASS - pretty much anything.

  • Full source maps for Javascript and CSS.

  • Full server-side rendering, with automatic Koa web server restarting on code changes. This ensures the initial HTML render will always reflect your latest code changes.

To get started, simply run:

npm start

A server will be started on http://localhost:3000

Production mode

In production mode, the following happens:

  • All assets are optimised and minified. Javascript, CSS, images, are all compiled down to static files that will appear in dist.

  • Assets are also compressed into .gz (Gzip) and .br (Brotli) versions, which are served automatically to all capable browsers.

  • If files have been generated in a previous run, they will be re-used on subsequent runs. This ensures really fast server start-up times after the initial build.

To build and run for production, use:

npm run production

Files will be generated in ./dist, and a server will also be spawned at http://localhost:3000

Clean the cached production build with npm run clean, or run npm run clean-production to both clean and re-run the production build, as needed.

Build mode

If you only want to build assets and not actually run the server, use:

npm run build:production

This is used in the Dockerfile, for example, to pre-compile assets and ensure faster start-up times when spawning a new container.

Static bundling for client-only SPAs

If you're targeting a client-only SPA and hosting statically, you probably don't want to run a Koa web server to handle HTTP requests and render React.

Instead, you can use static mode, which produces the client-side JS, CSS and assets files, along with an index.html for minimal bootstrapping, and dumps them in dist/public.

You can then upload the contents of that folder wherever you like - et voila, you'll have a working client-side Single Page App!

There are two static modes available -- for dev and production:

### Development (hot-code reload)

Just like the full-stack version, dev mode gives you hot code reloading, so changes to your local files will be pushed to the browser.

To activate static dev mode, just run:

npm run dev:static

Your client-side SPA will be online at http://localhost:3000, just like normal.

### Production (static deployment)

To build your client-side files ready for production deployment, run:

npm run build:static

You'll get everything in that 'regular' building provides you with plus a index.html to bootstrap your JS, just without the server parts.

Modifying the index.html template

If you want to make changes to the index.html file that's used for static bundling, edit src/views/static.html

NPM commands

Here's a list of all the NPM script commands available out-the-box:

Command What it does
npm run build:production Builds production-ready client/server bundles, but doesn't start a server.
npm run build:static Builds production-ready client bundle and index.html; ignores server bundling.
npm run clean Removes the dist folder, and any previously built client/server bundle.
npm run dev Runs a univeral dev server in memory; auto restarts on code changes and uses hot-code reload in the browser. Does not output anything to dist.
npm run dev:static Runs a client-only dev server using [src/views/static.html] as the template; full hot-code reload. Also doesn't output anything to dist.
npm run production Builds and runs a production-ready client/server bundle. If previously built, will re-use cached files automatically (run npm run clean to clear cache.)
npm run production:clean Same as above, but cleans dist first to ensure a fresh re-build.
npm start Shortcut for npm run dev.

Project layout

The important stuff is in src.

Here's a quick run-through of each sub-folder and what you'll find in it:

  • src/components - React components. Follow the import flow at root.tsx to figure out the component render chain and routing. I've included an example component that shows off some Apollo GraphQL and MobX features, including incrementing a local counter and pulling top news stories from Hacker News (a live GraphQL server endpoint.)

  • src/entry - The client and server entry points, which call on src/components/root.tsx to isomorphically render the React chain in both environments.

  • src/global - A good place for anything that's used through your entire app, like global styles. I've started you off with a styles.ts that sets globally inlined Emotion CSS, as well as pulls in a global .scss file -- to show you how both types of CSS work.

  • src/lib - Internal libraries/helpers. There's an apollo.ts which builds a universal Apollo Client. Plus, Koa middleware to handle hot-code reloading in development and some other Webpack helpers.

  • src/queries - Your GraphQL queries. There's just one by default - for pulling the top stories from Hacker News to display in the example component.

  • src/runner - Development and production runners that spawn the Webpack build process in each environment.

  • src/views - View components that fall outside of the usual React component chain, for use on the server. In here, ssr.tsx takes care of rendering the root HTML that's sent down the wire to the client. Note this is also a React component - your whole app will render as React! - and static.html serves as a template for rendering a client-side SPA. Update it as needed.

  • src/webpack - The Webpack 4 configuration files that do the heavy lifting to transform our Typescript code, images and CSS into optimised and minified assets that wind up in the dist folder at the root. Handles both the client and server environments.

You'll also find some other useful goodies in the root...

  • .env - Change your GRAPHQL server endpoint, WS_SUBSCRIPTIONS=1 for built-in WebSocket support, HOST if you want to bind the server to something other than localhost, and LOCAL_STORAGE_KEY to set the root key for saving MobX state locally in the client for automatic re-loading in a later session.

  • .nvmrc - Specify your preferred Node.js version, for use with NVM and used by many continuous deployment tools. Defaults to v12.2.0

  • codegen.yml - Settings for GraphQL Code Generator (which you can run with npm run gen:graphql to generate types/HOCs based on your GraphQL queries/mutations.)

  • netlify.toml - Build instructions for fast Netlify deployments. Tip: To quickly deploy a demo ReactQL app, click here.

  • types - Some basic types that allow you to import fonts, images, CSS/SASS/LESS files, and allow use of the global SERVER boolean and GRAPHQL endpoint data in your IDE.

  • Typescript configuration via tsconfig.json

  • A sample multi-build Dockerfile based on Node 11.8 and Alpine, for quickly deploying your code base to production.
