Show HN: Orange Cheeto Browser extension that replaces Trump with nicknames
cheetodon.comI built a browser extension that does text replacement across all websites -- specifically replacing "Trump" with rotating humorous nicknames.
The interesting technical bits:
- TreeWalker for DOM traversal (skips scripts, inputs, contenteditable, iframes)
- MutationObserver with debouncing for SPAs and dynamically loaded content
- Fisher-Yates shuffle bag for even nickname distribution (no repeats until all are used)
- Case preservation via regex (TRUMP -> MANGO MUSSOLINI, Trump -> Mango Mussolini)
- CSS-only animations with prefers-reduced-motion support
- Zero dependencies, plain JS, Manifest V3
The architecture is generic enough to fork for any text replacement use case. All the replacement logic lives in a single file.
No external requests, no analytics, no data leaves the browser. Settings sync via Chrome Storage / browser.storage.
Available for Chrome, Firefox, and Safari. Free.
Feedback on the implementation welcome -- the code is straightforward and I'd rather someone tell me my MutationObserver setup is wrong than find out the hard way.
