Usage

Base example

// src/routes.ts
import {lazy} from '@rambler-tech/react-toolkit/client'

const MainPage = lazy(() => import('./pages/main'))
const AboutPage = lazy(() => import('./pages/about'))

export const routes = [
  {
    path: '/',
    Component: MainPage
  },
  {
    path: '/about',
    Component: AboutPage
  }
]

// src/server.ts
import express from 'express'
import {renderToStream} from '@rambler-tech/react-toolkit/server'
import {routes} from './routes'

const assets = require(process.env.RAZZLE_ASSETS_MANIFEST)

const server = express()

server
  .use(express.static(process.env.RAZZLE_PUBLIC_DIR))
  .get('/*', async (req, res) => {
    try {
      const {css: styles, js: scripts} = assets.client

      await renderToStream({
        req,
        res,
        routes,
        styles,
        scripts
      })
    } catch (error) {
      console.error(error)
    }
  })

export default server

// src/client.ts
import {hydrateFromStream} from '@rambler-tech/react-toolkit/client'
import {routes} from './routes'

hydrateFromStream({routes})

Data fetching

import React from 'react'
import {PageComponent} from '@rambler-tech/react-toolkit/client'
import {api} from './api'

export interface MainPageProps {
  someProp: any
}

const MainPage: PageComponent<MainPageProps> = ({someProp}) => (
  <div>
    <h1>Main page</h1>
    <p>{someProp}</p>
  </div>
)

MainPage.getInitialData = async () => {
  const {someProp} = await api.getSomeProp()

  return {someProp}
}

export default MainPage

Pages meta data

import React from 'react'
import {PageComponent} from '@rambler-tech/react-toolkit/client'

const MainPage: PageComponent = () => (
  <div>
    <h1>Main page</h1>
    <p>...</p>
  </div>
)

MainPage.getMetaData = () => ({
  title: 'Main page',
  description: '...',
  'og:image': '...'
  canonical: '...'
})

export default MainPage

Getting the meta data is called after the data fetching, so the fetched data enriches the context passed to the getMetaData

import React from 'react'
import {PageComponent} from '@rambler-tech/react-toolkit/client'

const MainPage: PageComponent = () => (
  <div>
    <h1>Main page</h1>
    <p>...</p>
  </div>
)

MainPage.getInitialData = async () => {
  const {someProp} = await api.getSomeProp()

  return {someProp}
}

MainPage.getMetaData = ({data}) => ({
  title: `Main page: ${data.someProp}`
})

export default MainPage

Redirects

import React from 'react'
import {PageComponent} from '@rambler-tech/react-toolkit/client'
import {api} from './api'

export interface MainPageProps {
  someProp: any
}

const MainPage: PageComponent<MainPageProps> = ({someProp}) => (
  <div>
    <h1>Main page</h1>
    <p>{someProp}</p>
  </div>
)

MainPage.getInitialData = async () => {
  const user = await api.getCurrentUser()

  if (!user) {
    return {
      redirect: '/login'
    }
  }
}

export default MainPage

Custom Layout

For adding your own providers, markup and styles on top of pages and routing

// src/layout.tsx
import React, {FC, ReactNode} from 'react'
import {ThemeProvider} from 'awesome-ui'
import styles from './styles.module.css'

export interface MyLayoutProps {
  children: ReactNode
}

export const MyLayout: FC<MyLayoutProps> = ({children}) => {
  return (
    <ThemeProvider>
      <main className={styles.main}>{children}</main>
    </ThemeProvider>
  )
}

// src/server.ts
import express from 'express'
import {renderToStream} from '@rambler-tech/react-toolkit/server'
import {routes} from './routes'
import {MyLayout} from './layout'

const assets = require(process.env.RAZZLE_ASSETS_MANIFEST)

const server = express()

server
  .use(express.static(process.env.RAZZLE_PUBLIC_DIR))
  .get('/*', async (req, res) => {
    try {
      const {css: styles, js: scripts} = assets.client

      await renderToStream({
        req,
        res,
        routes,
        styles,
        scripts,
        Layout: MyLayout
      })
    } catch (error) {
      console.error(error)
    }
  })

export default server

// src/client.ts
import {hydrateFromStream} from '@rambler-tech/react-toolkit/client'
import {routes} from './routes'
import {MyLayout} from './layout'

hydrateFromStream({
  routes,
  Layout: MyLayout
})

Custom Document

For adding custom styles, scripts, meta tags and for more flexible customization of the entire document

// src/document.tsx
import React, {FC, ReactNode} from 'react'
import {
  Meta,
  Preloads,
  Styles,
  Scripts,
  State
} from '@rambler-tech/react-toolkit/client'

export interface MyDocumentProps {
  children: ReactNode
}

export const MyDocument: FC<MyDocumentProps> = ({children}) => (
  <html lang="ru">
    <head>
      <meta httpEquiv="X-UA-Compatible" content="IE=edge" />
      <meta charSet="utf-8" />
      <meta name="viewport" content="width=device-width, initial-scale=1" />
      <Meta />
      <link rel="manifest" href="/manifest.json" />
      <Preloads />
      <link
        rel="preconnect"
        href="https://mc.yandex.ru"
        crossOrigin="anonymous"
      />
      <Styles />
    </head>
    <body>
      {children}
      <State />
      <Scripts />
      <script src="https://vp.rambler.ru/player/sdk.js" async />
    </body>
  </html>
)

// src/server.ts
import express from 'express'
import {renderToStream} from '@rambler-tech/react-toolkit/server'
import {routes} from './routes'
import {MyDocument} from './document'

const assets = require(process.env.RAZZLE_ASSETS_MANIFEST)

const server = express()

server
  .use(express.static(process.env.RAZZLE_PUBLIC_DIR))
  .get('/*', async (req, res) => {
    try {
      const {css: styles, js: scripts} = assets.client

      await renderToStream({
        req,
        res,
        routes,
        styles,
        scripts,
        Document: MyDocument
      })
    } catch (error) {
      console.error(error)
    }
  })

export default server

// src/client.ts
import {hydrateFromStream} from '@rambler-tech/react-toolkit/client'
import {routes} from './routes'
import {MyDocument} from './document'

hydrateFromStream({
  routes,
  Document: MyDocument
})

Page transition mode

By default, router uses blocked transition mode, and will wait for getInitialData to get completed to show the next page.

If your want show the next page with spinner or skeleton while getInitialData is pending, use wait-for-data transition mode.

And if your want show the next page with spinner or skeleton only while lazy page is pending, use instant transition mode.

// src/routes.ts
import {lazy} from '@rambler-tech/react-toolkit/client'
import {Placeholder} from './components/placeholder'

const MainPage = lazy(() => import('./pages/main'))
const AboutPage = lazy(() => import('./pages/about'))

export const routes = [
  {
    path: '/',
    Placeholder,
    Component: MainPage
  },
  {
    path: '/about',
    Placeholder,
    Component: AboutPage
  }
]

// src/client.ts
import {
  hydrateFromStream,
  TransitionMode
} from '@rambler-tech/react-toolkit/client'
import {routes} from './routes'

hydrateFromStream({
  routes,
  transition: TransitionMode.INSTANT
})
