This repository contains an HTTP server implemented using Express.js, designed to respond to GET requests on the /data endpoint. The server accepts query parameters n and m, allowing users to retrieve file content. The script index.js generates 35 data files, each approximately 100MB in size, filled with random text content.

To retrieve file content, make a GET request to the /data endpoint with the following query parameters:

• n: File number (required)
• m: Line number (optional)

If both n and m are provided, the server returns the content of the specified file at the specified line number. If only n is provided, the entire content of the specified file is returned. The server also implements error handling for cases such as non-existent line numbers or file read errors.

To enhance the server's responsiveness, caching mechanisms have been implemented. This stores frequently accessed file content, reducing the need for repeated file reads and significantly improving overall performance.

Consider parallelizing file reads, especially for requests requiring the entire file content. This optimization can boost performance by efficiently handling multiple concurrent requests simultaneously.

For large files, the server optimizes by streaming responses instead of buffering the entire content in memory. This not only enhances memory efficiency but also ensures a more responsive experience for users.
