Installation

yarn add @shopify/react-server

Rails Usage

We provide a gem to automagically setup a proxy controller for react-server.

Node Usage

Node apps require a server entry point that calls the createServer function. At the minimum, this function requires a render function that renders the main <App /> component.

import React from 'react';
import {createServer} from '@shopify/react-server';
import {Context} from 'koa';
import App from '../app';

const app = createServer({
  port: process.env.PORT ? parseInt(process.env.PORT, 10) : 8081,
  ip: process.env.IP,
  assetPrefix: process.env.CDN_URL || 'localhost:8080/assets/webpack',
  render: (ctx: Context) => {
    const whatever = /* do something special with the koa context */;
    // any special data we add to the incoming request in our rails controller we can access here to pass into our component
    return <App server location={ctx.request.url} someCustomProp={whatever}  />;
  },
});
export default app;

If you already have an existing node server, you can opt in to using only the render middleware provided by this package. See createRender().

Webpack Plugin

We also provide a webpack plugin to automatically generate the server and client entries for an application.

Deployment (Shopify specific)

For Shopifolk, we have a walkthrough for getting an app ready to deploy.

API

createServer()

Creates a full Koa server which renders an @shopify/react-html application.

import {createServer} from '@shopify/react-server';

The createServer function takes an Options object of the following interface.

interface Options {
  // the port to bind
  port?: number;
  // the ip to run the application on
  ip?: string;
  // the full base url for the cdn if applicable
  assetPrefix?: string;
  // the name of the asset on the cdn, or a function of Koa.Context to a name
  assetName?: string | (ctx: Context) => string;
  // any additional Koa middleware to mount on the server
  serverMiddleware?: compose.Middleware<Context>[];
  // a function of `(ctx: Context, data: {locale: string}): React.ReactElement<any>`
  render: RenderFunction;
  // whether to run in debug mode
  debug?: boolean;
  // a function similar to option but used to customize the production SSR error page
  // note: using this assumes that there is an entry point named `error` in your project
  renderError: RenderFunction;
  // Control when to render raw stack trace, defaults to development only.
  renderRawErrorMessage?: boolean;
  // additional props to pass into the Html component, or a function that takes a Koa.Context and returns a props object
  // See https://github.com/Shopify/quilt/blob/main/packages/react-html/README.md#html-
  htmlProps?: HtmlProps | (ctx: Context) => HtmlProps
}

It returns a running Koa server.

createRender()

Creates a Koa middleware which renders an @shopify/react-html application.

import {createRender} from '@shopify/react-server';

The createRender function takes two arguments. The first is a render function that should return the main component at the top of the application tree in JSX. This function receives the full Koa server context which can be used to derive any necessary props to feed into the main component.

The second argument is a subset of @shopify/react-effect#extract's options which are simply delegated to the extract call within the createRender middleware.

Options

It returns a Koa middleware.
