Question 1

Filenamify vs slugify: which one should I use?

Accepted Answer

Use filenamify for creating safe filenames across operating systems by replacing reserved characters. Slugify is better for generating URL-friendly slugs with hyphen separation. Choose based on whether you need file naming or URL optimization.

Question 2

How to use filenamify in a React app for file uploads?

Accepted Answer

Import the browser version ('filenamify/browser') to avoid Node.js dependencies. Use it to sanitize user-provided filenames before saving or uploading files, ensuring cross-platform safety in client-side code.

Question 3

Does filenamify handle emojis and special Unicode characters?

Accepted Answer

Yes, it preserves Unicode characters like emojis during truncation by avoiding grapheme splitting. It also normalizes Unicode whitespace and removes control characters for clean output.

Question 4

What happens if a filename exceeds the maxLength with a long extension?

Accepted Answer

Filenamify truncates only the base filename, keeping the extension intact. If the extension itself is longer than maxLength, the result may exceed the limit, so you need to manually check for edge cases.

Question 5

Can I validate a filename without modifying it using filenamify?

Accepted Answer

No, filenamify always modifies the string to make it safe. For validation without changes, use the related 'valid-filename' module to check if a string is already a valid filename.

Question 6

Is filenamify good for server-side file processing in Node.js?

Accepted Answer

Yes, it's ideal for Node.js backends, especially with filenamifyPath for handling full paths. It ensures filenames from user input or dynamic content don't cause filesystem errors on any OS.
