​

Common Issues and Solutions

import dynamic from "next/dynamic";

const CapsuleComponent = dynamic(() => import("@usecapsule/react-sdk").then((mod) => mod.CapsuleComponent), {
  ssr: false,
});

/** @type {import('next').NextConfig} */
const nextConfig = {
  transpilePackages: [
    "@usecapsule/web-sdk",
    "@usecapsule/react-sdk",
    // Add any other Capsule-related packages here
  ],
  // ... other configurations
};

module.exports = nextConfig;

import "@usecapsule/react-sdk/dist/index.css";

function MyApp({ Component, pageProps }) {
  return <Component {...pageProps} />;
}

export default MyApp;

NEXT_PUBLIC_CAPSULE_API_KEY=your_api_key_here

const capsule = new Capsule(Environment.BETA, process.env.NEXT_PUBLIC_CAPSULE_API_KEY);

/** @type {import('next').NextConfig} */
const nextConfig = {
  // ... other configs
  webpack: (config, { isServer }) => {
    if (!isServer) {
      config.resolve.fallback = {
        ...config.resolve.fallback,
        crypto: require.resolve("crypto-browserify"),
        stream: require.resolve("stream-browserify"),
        buffer: require.resolve("buffer"),
      };
    }
    return config;
  },
};

module.exports = nextConfig;

Best Practices

1. Use the Latest Versions: Always use the latest versions of Next.js and Capsule SDK to ensure compatibility and access to the latest features.

2. Client-Side Rendering for Capsule Components: Whenever possible, render Capsule components on the client-side to avoid SSR-related issues.

3. Error Boundary: Implement error boundaries to gracefully handle any runtime errors related to Capsule integration.

4. Environment-Specific Configurations: Use Next.js environment configurations to manage different settings for development and production environments.

By following these troubleshooting steps and best practices, you should be able to resolve most common issues when integrating Capsule with your Next.js application.
