@nhost/nextjs

Use Nhost with NextJS on SSR mode

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:

# With npm
npm install @nhost/nextjs graphql

# With Yarn
yarn add @nhost/nextjs graphql

Initializing

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

import type { AppProps } from 'next/app'

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

const nhost = new NhostClient({
  subdomain: '<Your Nhost project subdomain>',
  region: '<Your Nhost project region>'
})

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

export default MyApp

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.

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(
    { subdomain: '<project_subdomain>', region: '<project_region>' },
    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

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

# With Yarn
yarn add @nhost/react-apollo @apollo/client

Initializing

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

import type { AppProps } from 'next/app'

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

const nhost = new NhostClient({
  subdomain: '<Your Nhost app subdomain>',
  region: '<Your Nhost app region>'
})

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

export default MyApp
