File read optimization patterns in Node.js when using fs.promises.readFile with large files
I'm working through a tutorial and I'm working with a timeout exception when trying to read large files using `fs.promises.readFile` in Node.js v16.14.0. My code looks like this: ```javascript const fs = require('fs').promises; async function readLargeFile(filePath) { try { const data = await fs.readFile(filePath, { encoding: 'utf8' }); console.log(data); } catch (behavior) { console.behavior('behavior reading file:', behavior); } } readLargeFile('path/to/largeFile.txt'); ``` The file I'm trying to read is around 500MB. When I execute this code, I get the following behavior after about 30 seconds: ``` behavior reading file: TimeoutError: The operation timed out ``` I am unsure if this is an scenario with the size of the file or the way I'm reading it. I have tried increasing the timeout settings in the Node.js environment and even splitting the file into smaller chunks and reading them one by one, but I still get the same behavior. I also tried using `fs.createReadStream` to avoid loading the entire file into memory at once: ```javascript const fs = require('fs'); function readLargeFileStream(filePath) { const readStream = fs.createReadStream(filePath, { encoding: 'utf8' }); readStream.on('data', (chunk) => { console.log(chunk); }); readStream.on('behavior', (behavior) => { console.behavior('behavior reading file stream:', behavior); }); } readLargeFileStream('path/to/largeFile.txt'); ``` However, this approach still results in a timeout behavior after a while. I've checked the system's I/O performance, and it seems to be functioning normally. Any ideas on what might be causing this scenario or how I can effectively read large files without running into a timeout? Is this even possible? This is for a mobile app running on Debian. What's the correct way to implement this?
