Hacker Approved page: https://hackerapproved.com/p/codemirror/

9 people recommended CodeMirror in Hacker News comments, 6 had mixed feelings and 1 criticized it, November 2025 to October 2026. It was recommended in 5 of 12 months, in 8 threads. It does not meet the Hacker Approved badge rule.

**Verdict:** Recommended as a flexible, lightweight, mobile-friendly code editor library that handles browser quirks for you. Common caveats: the docs are sometimes lacking, and it needs a lot of client-side JavaScript.
