This example demonstrates how to set up a Next.js application with a custom Express server using TypeScript. It shows the server-side configuration that prepares the Next.js app and routes all incoming requests through Next’s request handler. The code uses `next` from the Next.js package, `express` for the HTTP server, and `app.getRequestHandler()` to integrate Express with Next’s routing. The server listens on a configurable port (defaulting to 3000) and handles errors by logging and exiting. The rendering approach relies on Next’s built-in server-side rendering, with the environment set by `NODE_ENV`.

Override Next.js tsconfig for express local development

This example demonstrates how to override a Next.js TypeScript configuration for local Express server development. It shows a `tsconfig.server.json` file that extends the main project’s `tsconfig.json`, switching the module system to CommonJS and redirecting output to a `dist` folder. The file uses TypeScript’s `extends`, `compilerOptions` with `module`, `outDir`, and `noEmit`, plus an `include` array targeting the `server` directory. This setup allows Express code to compile separately from the Next.js client build.

Next.js Typescript error page

This example shows a Next.js custom error page that displays either a server-side or client-side error message based on the HTTP status code. It uses Next.js’s `getInitialProps` lifecycle method to retrieve the status code from the `res` or `err` objects in the `NextPageContext`. The component conditionally renders text indicating whether the error occurred on the server or client, defaulting to a 404 status if no error is present. The code relies on React’s functional component pattern and Next.js’s built-in error handling.

This example demonstrates a minimal Express.js web server with three routes: a root path returning "Hello World!" and two additional paths, `/login` and `/signup`, each returning a French-language message prompting the user to log in or create an account. The code uses the Express framework to define these HTTP GET endpoints and listens on port 3000, logging a startup message to the console. The visualization shows the basic structure of a server-side routing setup, with no data or rendering involved beyond plain text responses.

This example presents a web-based client-server application that serves static files and handles socket connections. The server is built with Express and Socket.IO, listening on a configurable port, and delegates all routes to a single `index.html` file. It uses the `body-parser` middleware for JSON parsing and the `path` module to resolve file locations. The rendering approach is not specified, but the code clearly establishes the infrastructure for delivering a front-end visualization, with the server acting as the backbone for real-time communication and static asset delivery.

This example demonstrates a basic Express.js web server that handles file uploads and form submissions through HTTP POST requests. The code uses the `express` framework and `connect-form` middleware to parse multipart form data. It serves an HTML form at the root route, then processes submitted text fields and optional image files on the `/` POST endpoint, logging parsed fields and files to the console before redirecting back. The form action uses `enctype="multipart/form-data"` and the server listens on port 3000.

Advance Topic About Server Credential

This example demonstrates key differences between Node.js server credential and header-handling techniques, contrasting `response.setHeader` with `response.writeHead` for setting status codes, content-length, content-type, and cookies. It also covers Express routing parameters (`req.params` and `req.query`) with links to Stack Overflow discussions. The code shows practical use of JWT (via `jwt-simple`) for token generation and verification, and Bcrypt for password hashing and comparison, alongside guidance on creating custom Express middleware from the official documentation. The gist serves as a reference card for common authentication and HTTP response patterns.

This example shows an order-service application built with React, managing order data through a PostgreSQL database via Sequelize and Express. The code defines REST API endpoints for creating, retrieving, and updating orders, using JSON validation with Ajv and TypeBox schemas. It integrates RabbitMQ through amqplib for message queuing, JWT token verification for authentication, and includes comprehensive Jest testing with nock for HTTP mocking and Sinon for spies. The visualization demonstrates a server-side Node.js architecture with async/await patterns, error handling middleware, and logging.

This example demonstrates a lightweight Express server that acts as a CORS proxy for a joke API, enabling browser-based requests to bypass cross-origin restrictions. The code uses the `express` and `request` libraries to define a route, `/jokes/random`, which forwards requests to `https://joke-api-strict-cors.appspot.com/jokes/random` and relays the JSON response back to the client. A middleware sets the `Access-Control-Allow-Origin` header to `*`, allowing any frontend to access the proxied data. The server listens on a configurable port, defaulting to 3000, and handles errors by returning a JSON error object. This setup illustrates a simple server-side solution for enabling client-side data fetching from a restricted external source.
