Vite 原始碼解讀 – createServer part1

Vite is a next-generation frontend build tool that is both fast and lightweight. It leverages the power of modern JavaScript features and the native ES module system to provide a more efficient development experience. In this article, we will be diving into the source code of Vite and exploring the createServer function.

Understanding createServer

The createServer function is a crucial part of Vite’s architecture as it is responsible for creating the development server. This server is used to serve the application during development and provides features such as hot module replacement and fast rebuilds.

Let’s take a look at a simplified version of the createServer function:

function createServer(options) {
  const server = http.createServer((req, res) => {
    // handle incoming requests
  });

  server.listen(options.port, () => {
    console.log(`Server running on port ${options.port}`);
  });

  return server;
}

In this example, we can see that the createServer function takes in an options object that allows the user to specify configurations such as the port number. It then creates a new http server using Node.js’s http module. The server is set to listen on the specified port, and we log a message to the console to indicate that the server is running.

Conclusion

Understanding the createServer function is crucial for comprehending how Vite handles the development server. By diving into the source code, we can gain valuable insights into how Vite leverages modern JavaScript features and native browser capabilities to provide a more efficient development experience.
