I was wondering, what is Asynchronous File Fething. Here, I look at four advantages, explaining the advantages of asynchronously fetching files We know that it enhances the performance and ensures the a node server remains resposive, even when handling intensive I/O tasks. Let's see more of why.

Why are the files from the system fetched asynchronously?

Fetching files asynchronously offers several benefits, especially in a Node.js environment like Next.js.

Non-blocking I/O

  • Node.js is built around an event-driven, non-blocking architecture. This means that the application can handle many operations at the same time without waiting for each one to finish.

Improved Performance

  • File I/O can be slow, particularly if the files are large or stored on a slower medium. Asynchronous operations allow the application to initiate the file read and then move on to other work, rather than waiting idly.

Concurrency

  • Asynchronous operations enable handling multiple file operations concurrently. This is crucial in a web server context where you might have multiple requests that require file access. By not blocking the main thread, your application can efficiently manage these simultaneous operations.

Seamless Integration with Next.js

In Next.js, page components can be asynchronous. Marking the component as async and using await allows you to easily integrate asynchronous data fetching (like file reading) into the server-side rendering process.
