Running React and Express with concurrently

In modern web development, building full-stack applications with a frontend framework like React and a backend framework such as Express.js is common practice. React provides an interactive user interface, while Express handles server-side logic, data storage, and API endpoints. Efficient development and testing of these applications require running React and Express servers simultaneously, which can be cumbersome if done manually through separate terminal windows. The concurrently command-line tool simplifies this process by allowing multiple npm scripts to run in parallel from a single terminal window, streamlining the development workflow and enhancing productivity. By using concurrently, developers can start both servers with a single command, automatically restart them upon code changes, and consolidate console output for easier debugging. Custom configurations in concurrently allow developers to specify process names, colors, and output patterns for better clarity and scalability. This approach facilitates smooth integration between the React frontend and Express backend, supporting rapid iteration and improved developer experience when building full-stack applications.
