Get Started: React/Next.js Apps

Estimated time to read: 4 minutes

Integrate 'React/Next.js' apps with Arcana Auth SDK and onboard users via social login. Enable users to sign blockchain transactions with the in-app Arcana wallet.

Prerequisites

App must be registered via the Arcana Developer Dashboard: https://dashboard.arcana.network
Optionally configure auth settings such as social login, gasless transactions, wallet user experience, etc.

Supported Versions: React/NextJS, TypeScript

React 18.00 or higher
TypeScript 5.00 or higher

1. Install SDKs

npmyarn

npm install --save @arcana/auth @arcana/auth-react

yarn add @arcana/auth  @arcana/auth-react

2. Integrate

index.jsApp.js

import { StrictMode } from "react";
import { createRoot } from "react-dom/client";
import { AuthProvider } from "@arcana/auth";
import { ProvideAuth } from "@arcana/auth-react";
import App from "./App";

const rootElement = document.getElementById("root");
const root = createRoot(rootElement);

const provider = new AuthProvider(
  "xar_live_d7c88d9b033d100e4200d21a5c4897b896e60063"
);

root.render(
  <StrictMode>
    <ProvideAuth provider={provider}>
      <App />
    </ProvideAuth>
  </StrictMode>
);

import React from "react";
import { Auth } from "@arcana/auth-react";

export default function App() {
  return (
    <div className="App">
      <h1>Sample Auth React App</h1>
      <Auth />
    </div>
  );

Onboard Users

index.jsApp.js

import { StrictMode } from "react";
import { createRoot } from "react-dom/client";
import { AuthProvider } from "@arcana/auth";
import { ProvideAuth } from "@arcana/auth-react";

import App from "./App";

const rootElement = document.getElementById("root");
const root = createRoot(rootElement);
const provider = new AuthProvider(
  "xar_live_d7c88d9b033d100e4200d21a5c4897b896e60063",
  {
    network: "mainnet",
    theme: "light",
    connectOptions: {
      compact: true,
    },
    chainConfig: {
      chainId: "80001"
    }
  }
); //See SDK Reference Guide for optional parameters

root.render(
  <StrictMode>
    <ProvideAuth provider={provider}>
      <App />
    </ProvideAuth>
  </StrictMode>
);

import { Auth } from "@arcana/auth-react";

// Use <Auth/> to use the built-in, plug & play login UI
function App() {
  const [theme, setTheme] = React.useState("light");
  return (
    <div>
      <Auth theme={theme} />
    </div>
)}

export default App;

Sign Transactions

Use AuthProvider, the EIP-1193 provider offered by the SDK, to call supported JSON/RPC functions and Web3 wallet operations in the authenticated user's context.

That's all!

The 'React/Next.js' app is ready to onboard users and allow them to sign blockchain transactions.

3. Advanced Usage

AuthProvider Optional Parameters

Besides Client ID input parameter, you can optionally customize these settings in the AuthProvider constructor:

position: wallet position within the app context - left|right

theme: wallet theme - light|dark

connectOptions: compact mode for the built-in plug-and-play login UI - true|false

connectOptions: {
      compact: true // default - false
},

See AuthProvider constructor parameters for details.

Wallet Customization

Manage the user experience for signing blockchain transactions by configuring SDK usage. Specify the theme, branding settings of the in-app built-in Arcana wallet UI. Use wallet visibility and decide when to display the wallet UI in the app. Configure keyspace and enable the user experience of having the same wallet address across multiple apps integrated with the Arcana Auth SDK.

You can also replace the built-in wallet UI with a custom wallet UI.

Custom Login UI

You can onboard users through a custom login UI instead of the built-in plug-and-play one. See how to use custom login UI and onboard users in a 'React/Next.js' app.

Arcana JWT Token

loginTokenuserDIDToken

Upon successful authentication, Arcana Auth SDK returns a unique JWT token to the app called the Arcana JWT Token. App developers can access this token via getUser() method and refer to the loginToken field of the UserInfo object.

Developers can use this token to verify the user and subsequently generate another token for app use if required.

In the future, the Arcana JWT Token will be deprecated. Use userDIDToken to verify user.

Upon successful authentication, Arcana Auth SDK returns a unique DID token to the app called the Arcana DID Token. App developers can access this token via getUser() method and refer to the userDIDToken field of the UserInfo object.

Developers can use this token to verify the user and subsequently generate another token for app use.
