Para with Create React App (CRA)

This guide will walk you through the process of integrating the Para Modal into a Create React App (CRA) project that uses CRACO, ensuring a seamless way to manage user authentication and wallets.

If you haven’t already created your React app with CRA, follow the official CRA docs to scaffold a new project. Once you’ve set up CRA, you can install and configure CRACO: CRACO docs.

​

Prerequisites

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

​

Installing Dependencies

First, install the Para React SDK and React Query using your preferred package manager:

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

​

Setting Up Polyfills in CRACO

Para relies on certain Node.js modules that are not available in the browser by default (e.g., crypto, buffer, stream). You’ll need to configure polyfills via CRACO’s config to ensure those modules work properly.

Install the necessary polyfill packages before updating your configuration:

npm install crypto-browserify buffer stream-browserify

Then, modify your craco.config.js:

const webpack = require("webpack");

module.exports = {
  webpack: {
    configure: (webpackConfig) => {
      webpackConfig.resolve.fallback = {
        ...webpackConfig.resolve.fallback,
        crypto: require.resolve("crypto-browserify"),
        buffer: require.resolve("buffer/"),
        stream: require.resolve("stream-browserify"),
      };
      webpackConfig.plugins = [
        ...webpackConfig.plugins,
        new webpack.ProvidePlugin({
          process: "process/browser",
          Buffer: ["buffer", "Buffer"],
        }),
      ];
      return webpackConfig;
    },
  },
};

This configuration ensures that the Para SDK can properly utilize the necessary Node.js modules in your CRA environment.

​

Setting Up the Para SDK

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

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

const queryClient = new QueryClient();

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

import React from 'react';
import ReactDOM from 'react-dom/client';
import './index.css';
import App from './App';
import { Providers } from './providers';

const root = ReactDOM.createRoot(document.getElementById('root'));
root.render(
  <React.StrictMode>
    <Providers>
      <App />
    </Providers>
  </React.StrictMode>
);

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

function LoginButton() {
  const { openModal } = useModal();

  return (
    <>
      <button onClick={() => openModal()}>
        Sign in with Para
      </button>
      
      <ParaModal 
        appName="Your App Name"
        logo="/logo.png" 
      />
    </>
  );
}

export default LoginButton;

​

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"]}
/>
