Next.js

The Nhost Next.js client exports a React provider for Next.js and React hooks that make it easier to work with Nhost in your Next.js app. The Next.js client is built on top of the Nhost React client and exports the same hooks and helpers.

Installation​

Install the Nhost Next.js client, React client together with GraphQL:

npm install @nhost/nextjs graphql

Initializing​

Initialize a single nhost instance and wrap your app with the NhostProvider.

pages/_app.js
import type { AppProps } from 'next/app'

import { NhostClient, NhostProvider } from '@nhost/nextjs'

const nhost = new NhostClient({
  subdomain: '<your-subdomain>',
  region: '<your-region>'
})

function MyApp({ Component, pageProps }: AppProps) {
  return (
    <NhostProvider nhost={nhost} initial={pageProps.nhostSession}>
      <Component {...pageProps} />
    </NhostProvider>
  )
}

export default MyApp
info

The nhost instance created with the NhostClient above is the same as the JavaScript Nhost client.

Server-Side Rendering (SSR)​

You need to load the session from the server first from getServerSideProps. Once it is done, the _app component will make sure to load or update the session through pageProps.

pages/ssr-page.tsx
import { NextPageContext } from 'next'
import React from 'react'

import {
  getNhostSession,
  NhostSession,
  useAccessToken,
  useAuthenticated,
  useUserData
} from '@nhost/nextjs'

export async function getServerSideProps(context: NextPageContext) {
  const nhostSession = await getNhostSession('<Your Nhost Backend URL>', context)

  return {
    props: {
      nhostSession
    }
  }
}

const ServerSidePage: React.FC<{ initial: NhostSession }> = () => {
  const isAuthenticated = useAuthenticated()
  const user = useUserData()
  const accessToken = useAccessToken()

  if (!isAuthenticated) {
    return <div>User it not authenticated</div>
  }

  return (
    <div>
      <h1>{user?.displayName} is authenticated</h1>
      <div>Access token: {accessToken}</div>
    </div>
  )
}

export default ServerSidePage

Apollo GraphQL​

You can use Apollo's GraphQL Client together with Next.js and Nhost.

Installation​

npm install @nhost/react-apollo @apollo/client

Initializing​

Wrap the Next.js app with the NhostApolloProvider and make sure the NhostApolloProvider is nested inside the NhostProvider.

pages/_app.js
import type { AppProps } from 'next/app'

import { NhostClient, NhostProvider } from '@nhost/nextjs'
import { NhostApolloProvider } from '@nhost/react-apollo'

const nhost = new NhostClient({
  subdomain: '<your-subdomain>',
  region: '<your-region>'
})

function MyApp({ Component, pageProps }: AppProps) {
  return (
    <NhostProvider nhost={nhost} initial={pageProps.nhostSession}>
      <NhostApolloProvider nhost={nhost}>
        <Component {...pageProps} />
      </NhostApolloProvider>
    </NhostProvider>
  )
}

export default MyApp
