This guide will walk you through the process of integrating the ParaProvider with the ParaModal into your Next.js application,providing a seamless way to manage user authentication and wallets.

If you haven’t already set up your Next.js app, you can get started by creating a new project via the Next.js official docs.

Prerequisites

To use Para, you need an API key. This key authenticates your requests to Para services and is essential for integration.

Don’t have an API key yet? Request access to the Developer Portal to create API keys, manage billing, teams, and more.

Installing Dependencies

npm install @getpara/react-sdk @tanstack/react-query

Setting Up the Para SDK

Now that you’ve installed the necessary dependencies, let’s set up the Para SDK in your Next.js project using the recommended ParaProvider approach.

Create a Providers Component”>

First, create a Providers component that will wrap your application with both the QueryClientProvider (required for Para) and the ParaProvider:

"use client";

import { QueryClient, QueryClientProvider } from "@tanstack/react-query";
import { Environment, ParaProvider } from "@getpara/react-sdk";
import "@getpara/react-sdk/styles.css";

const queryClient = new QueryClient();

export function Providers({
  children,
}: Readonly<{
  children: React.ReactNode;
}>) {
  return (
    <QueryClientProvider client={queryClient}>
      <ParaProvider
        paraClientConfig={{
          apiKey: process.env.NEXT_PUBLIC_PARA_API_KEY || "",
          env: Environment.BETA,
        }}>
        {children}
      </ParaProvider>
    </QueryClientProvider>
  );
}

Para offers two hosted environments: Environment.BETA (alias Environment.DEVELOPMENT) for testing, and Environment.PROD (alias Environment.PRODUCTION) for live use. Select the environment that matches your current development phase.

Wrap Your App with Providers”

Next, wrap your root layout with the Providers component:

import { Providers } from './providers';

export default function RootLayout({
  children,
}: {
  children: React.ReactNode;
}) {
  return (
    <html lang="en">
      <body>
        <Providers>{children}</Providers>
      </body>
    </html>
  );
}

Add the Para Modal

Now you can include the ParaModal component in any client component within your application and use the ParaProvider hooks to control it:

"use client";

import { ParaModal, useModal } from "@getpara/react-sdk";

export function ParaButton() {
  const { openModal } = useModal();

  return (
    <>
      <button onClick={() => openModal()}>
        Sign in with Para
      </button>

      <ParaModal
        appName="Your App Name"
        logo="/para.svg"
      />
    </>
  );
}

The ParaModal will automatically connect to the ParaProvider context, so you don’t need to pass any additional props for functionality. You only need to customize its appearance.

Beta Testing Credentials In the BETA Environment, you can use any email ending in @test.getpara.com (like dev@test.getpara.com) or US phone numbers (+1) in the format (area code)-555-xxxx (like (425)-555-1234). Any OTP code will work for verification with these test credentials. These credentials are for beta testing only. You can delete test users anytime in the beta developer console to free up user slots.

Customizing the Para Modal

To provide the best experience for your users, you can customize the appearance of the Para Modal to match your application’s branding.

When rendering the ParaModal component, you can pass props to customize its appearance:

<ParaModal
  appName="Your App Name"
  logo="/logo.png"
  theme={{ backgroundColor: "#ffffff", foregroundColor: "#000000" }}
  oAuthMethods={["GOOGLE", "TWITTER", "DISCORD"]}
/>
