Question 1

How do I use emoji-regex to count emojis in a string?

Accepted Answer

Import the module, call the function to get the regex, then use methods like matchAll() to iterate over matches. The README provides a Node.js example showing how to count code points for each matched sequence.

Question 2

emoji-regex vs emoji-regex-xs: which one should I choose?

Accepted Answer

Use emoji-regex for deterministic, Unicode-compliant matching in production apps like image replacement. Choose emoji-regex-xs for a lighter, non-deterministic option when strict compliance isn't critical, such as quick prototyping.

Question 3

Does emoji-regex work with TypeScript?

Accepted Answer

Yes, it includes TypeScript definitions, so you can import it seamlessly in TypeScript projects without additional configuration. The npm package handles types out of the box.

Question 4

How to extract only smiley emojis using emoji-regex?

Accepted Answer

emoji-regex matches all emojis, so you'd need to filter results based on Unicode ranges or categories after matching. It doesn't support subset matching natively, requiring post-processing for specific emoji types.

Question 5

Is emoji-regex safe for server-side rendering in Node.js?

Accepted Answer

Yes, it's designed for Node.js and browser environments, but ensure you use the function export to avoid regex mutation issues. The global flag handling makes it reliable for SSR contexts.

Question 6

How to update emoji-regex for new emojis?

Accepted Answer

As a user, simply update the npm package to the latest version. Maintainers handle the underlying Unicode data updates via build scripts, as detailed in the README's maintenance section.
