@shopify/react-server
A simple library for React server-side rendering using @shopify/react-html
.
Table of contents
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
afterEachPass?(pass: Pass): any
see@shopify/react-effect#extract
betweenEachPass?(pass: Pass): any
see@shopify/react-effect#extract
It returns a Koa middleware.
