Saga

Next-generation ecommerce framework built with React and GraphQL.

Features

• GraphQL server backed by apollo-server-express, Objection.js, and PostgreSQL
• Full support for server-side rendering
• Code splitting with dynamic imports and react-loadable
• Sane webpack configurations
• JS hot reloading with react-hot-loader (@next) and webpack-dev-server
• CSS, SASS and css-modules support with hot reloading and no flash of unstyled content (css-hot-loader)
• Routing with react-router-v4
• Full production builds that do not rely on babel-node.
• Pre-configured testing tools with jest and enzyme to work with css modules, static files, and aliased module paths.

Development Mode

Copy environment variables and edit them if necessary:

cp .env.example .env

Then:

npm install
npm start

Direct your browser to http://localhost:3000.

Production Builds

Add environment variables the way you normally would on your production system.

npm run prod:build
npm run serve

Or simply:

npm run prod

If using Heroku, simply add a Procfile in the root directory. The postinstall script will do the rest.

web: npm run serve

Path Aliases

In package.json, there is a property named _moduleAliases. This object defines the require() aliases used by both webpack and node.

Aliased paths are prefixed with one of two symbols, which denote different things:

@ - aliased paths, e.g. @admin, @app, @middleware

$ - server paths that are built by babel, e.g. server/api

Aliases are nice to use for convenience, and lets us avoid using relative paths in our components:

// This sucks
import SomeComponent from '../../../components/SomeComponent';

// This is way better
import SomeComponent from '@shared/components/SomeComponent';

You can add additional aliases in package.json to your own liking.

Environment Variables

In development mode, environment variables are loaded by dotenv off the .env file in your root directory. In production, you'll have to manage these yourself.

An example with Heroku:

heroku config:set FOO=bar

CSS Modules

This project uses CSS Modules. Class names should be in camelCase. Simply import the .scss file into your component, for example:

├── components
│   ├── Header.js
│   ├── Header.scss

// Header.scss
.headerContainer {
  height: 100px;
  width: 100%;
}

// Header.js
import css from './Header.scss';

const Header = (props) => {
  return (
    <div className={css.headerContainer}>
      {...}
    </div>
  );
}

Server-side Rendering (SSR)

This project fully supports server side rendering. See Apollo's documentation on server-sider rendering.

Async / Await

This project uses async/await, available by default in Node.js v8.x.x or higher. If you experience errors, please upgrade your version of Node.js.

Testing

The default testing framework is Jest, though you can use whatever you want.

Tests and their corresponding files such as Jest snapshots, should be co-located alongside the modules they are testing, in a spec/ folder. For example:

├── components
│   ├── todos
│   │   ├── TodoForm
│   │   │   ├── spec
│   │   │   │   ├── TodoForm.test.js
│   │   │   ├── index.js
│   │   │   ├── index.scss

Tests can be written with ES2015, since it passes through babel-register.

Running Tests

To run a single test:

npm test /path/to/single.test.js

// Or, to watch for changes
npm run test:watch /path/to/single.test.js

To run all tests:

npm run test:all

// Or, to watch for changes
npm run test:all:watch

Running ESLint

npm run lint

Check the .eslintignore file for directories excluded from linting.

Changing the public asset path

By default, assets are built into dist/public. This path is then served by express under the path assets. This is the public asset path. In a production scenario, you may want your assets to be hosted on a CDN. To do so, just change the PUBLIC_ASSET_PATH environment variant.

Example using Heroku, if serving via CDN:

heroku config:set PUBLIC_ASSET_PATH=https://my.cdn.com
