next: Start the current application in development mode.

$ next dev

try on your machine

The command "next dev" is used in the context of Next.js, a popular React framework for building web applications. It is a command-line command used to start the development mode server in Next.js.

When you run "next dev" in the terminal within a Next.js project directory, it starts a development server that allows you to view and work on your application in a local development environment. It compiles all the necessary files, sets up hot module replacement (HMR) for faster development, and provides an optimized development experience.

By executing "next dev," you can view your application by opening it in your web browser at a specified URL, typically "http://localhost:3000". Any changes made to your code will automatically trigger hot reloading, meaning that the changes will be immediately reflected in the browser without needing to manually refresh the page.

This command also provides additional features like automatic compilation of TypeScript files, generating source maps for debugging purposes, and handling static assets and data fetching. It simplifies the development process by offering a smooth and efficient workflow within the Next.js framework.
