Frequently Asked Questions

Can browsers handle a 10MB text file?

Fetching and parsing 10MB of text in a browser is fine (~100–200ms). However, rendering 500K lines in the DOM will freeze the page. Use virtualization (react-window) to display only visible lines.

Should I read a 10MB text file into memory?

For server-side processing, yes — 10MB is small for modern servers. For browser/mobile apps, use streaming (ReadableStream) or chunked reading to avoid blocking the main thread.

How do I efficiently search through 500K lines?

Use a streaming approach: read line by line without loading the entire file. In Node.js, use readline.createInterface(). In Python, iterate the file object directly. Avoid loading the full content into a string for regex matching.
