Create React App (CRACO)

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 using your preferred package manager:

​

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:

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. This involves creating a client instance.

​

Creating a Para Client Instance

You can create the Para client instance in a dedicated file, such as clients/para.tsx, or as part of your state management logic. Below is a basic example:

import Para, { Environment } from "@getpara/react-sdk";

const para = new Para(Environment.BETA, process.env.NEXT_PUBLIC_PARA_API_KEY);

export default para;

This step initializes the Para SDK with your API key and the chosen environment. If successful, you should see the Para instance logged in your console (if you choose to console.log it).

​

Integrating the Para Modal

Next, integrate the Para Modal into your React component by importing the ParaModal component from the Para SDK, adding a button to trigger the modal, and managing the modal’s state.

import React, { useState } from "react";
import { ParaModal } from "@getpara/react-sdk";
import para from "./clients/para"; // Adjust the path to where your para instance is located
import "@getpara/react-sdk/styles.css";

function App() {
  const [isOpen, setIsOpen] = useState(false);

  return (
    <div>
      <button onClick={() => setIsOpen(true)}>Sign in with Para</button>
      <ParaModal
        para={para}
        isOpen={isOpen}
        onClose={() => setIsOpen(false)}
      />
    </div>
  );
}

export default App;

This creates a button that, when clicked, opens the Para Modal for user authentication. The Para Modal handles all aspects of user authentication and wallet management.

​

Customizing the Para Modal

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

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

<ParaModal
  para={para}
  isOpen={isOpen}
  onClose={() => setIsOpen(false)}
  appName="Your App Name"
  logo="https://yourapp.com/logo.png"
  theme={{ backgroundColor: "#ffffff", foregroundColor: "#000000" }}
  oAuthMethods={["GOOGLE", "TWITTER", "DISCORD"]}
/>
