Webpack Proxy

Webpack Proxy is a development server feature in Webpack that forwards API requests from a frontend application to a backend server during development. It allows developers to avoid CORS (Cross-Origin Resource Sharing) issues by proxying requests through the same origin as the frontend. This tool is commonly used in web development workflows to simulate production-like environments locally.

Also known as: webpack-dev-server proxy, webpack proxy configuration, devServer proxy, webpack proxy setup, webpack proxy middleware

Why learn Webpack Proxy?

Developers should use Webpack Proxy when building frontend applications that need to communicate with backend APIs during development, especially when the backend runs on a different port or domain. It simplifies debugging by eliminating CORS errors and enables hot module replacement without restarting the backend server. This is particularly useful in microservices architectures or when working with third-party APIs that require same-origin requests.
