Overview:

The article discusses the integration of Next.js and NestJS for a project migration. It highlights the benefits of using Next.js, particularly the API routes feature, and the challenge of integrating it with an existing NestJS backend. The solution proposed involves utilizing Dynamic API Routes to connect Next.js with the NestJS application efficiently.

Features:

• Next.js Integration: Learn how to integrate Next.js with an existing NestJS backend.
• Dynamic API Routes: Implement a Catch-All-Route to forward incoming requests to the NestJS instance.
• HTTP Server Integration: Utilize the http.Server handlers to connect NestJS with Next.js seamlessly.

Installation:

1. Initialize the NestJS application:

   // Initialize the NestJS application
   const app = await NestFactory.create(AppModule);
   await app.init();
   

2. Get the http.Server from the NestJS application:

   // Get the integrated http.Server
   const server = app.getHttpServer();
   

3. Get the registered request handler from the http.Server:

   // Get the registered request handler
   const handlers = server.listeners('request');
   const requestHandler = handlers[0]; // Get the required request handler
   

Summary:

The article delves into the process of integrating Next.js with NestJS using Dynamic API Routes. It tackles the challenge of connecting the two frameworks without the need for custom servers. By leveraging the http.Server handlers provided by NestJS, the integration process becomes more straightforward. The approach presented in the article offers a method to seamlessly connect Next.js with any http.Server-based framework, enhancing the overall development and deployment experience.
