Simple setup for @solana/web3.js v2 in a React/React Native app. Be sure to install`@solana/web3.js@2` in your project!

app-layout.tsx

import { ReactNode } from 'react'
import { SolanaClientProvider } from './solana-client-provider'

function AppLayout({ children }: { children: ReactNode }) {
  return <SolanaClientProvider rpc='https://api.devnet.solana.com'>
    {children}
  </SolanaClientProvider>
}

solana-client-provider.tsx

import React, { ReactNode } from 'react'
import { createSolanaClient, SolanaClient, SolanaClientConfig } from './solana-client'

const SolanaClientContext = React.createContext<SolanaClient>({} as SolanaClient)

export function SolanaClientProvider({ children, ...props }: SolanaClientConfig & { children: ReactNode }) {
  const client = createSolanaClient(props)

  return <SolanaClientContext.Provider value={client}>{children}</SolanaClientContext.Provider>
}

export function useSolanaClient() {
  return React.useContext(SolanaClientContext)
}

solana-client.ts

import { createSolanaRpc, Rpc, SolanaRpcApiDevnet } from '@solana/rpc'
import { createSolanaRpcSubscriptions, RpcSubscriptions, SolanaRpcSubscriptionsApi } from '@solana/web3.js'

export type SolanaClient = {
  rpc: Rpc<SolanaRpcApiDevnet>
  rpcSubscriptions: RpcSubscriptions<SolanaRpcSubscriptionsApi>
}

export interface SolanaClientConfig {
  rpc: string
  rpcSubscriptions?: string
}

export function createSolanaClient(config: SolanaClientConfig): SolanaClient {
  const rpc = createSolanaRpc(config.rpc)
  const rpcSubscriptions = createSolanaRpcSubscriptions(
    // Figure out the subscriptions URL if it's not provided.
    config.rpcSubscriptions ?? config.rpc.replace('https', 'wss').replace('8899', '8900'),
  )
  return {
    rpc,
    rpcSubscriptions,
  }
}

Work on the new wallet adapter is still going on. I hope there will be a new template by next week this time. Sorry for the delays here.

Be sure to check my X if you want to see when I publish the new template.
