On Node.js v25, the log prefix in the terminal stopped working - instead of seeing something like: ``` [2026-03-05 23:00:00.000] [LOG] [app] Starting MagicMirror: v2.35.0 ``` the output was: ``` [2026-03-05 23:00:00.000] :pre() Starting MagicMirror: v2.35.0 ``` Reported in #4048. ## Why did it break? The logger used the `console-stamp` package to format log output. One part of that formatting used `styleText("grey", ...)` to color the caller prefix gray. Node.js v25 dropped `"grey"` as a valid color name (only `"gray"` with an "a" is accepted now). This caused `styleText` to throw an error internally - and `console-stamp` silently swallowed that error and fell back to returning its raw `:pre()` format string as the prefix. Not ideal. ## What's in this PR? **1. The actual fix** - `"grey"` → `"gray"`. **2. Cleaner stack trace approach** - the previous code set `Error.prepareStackTrace` *after* creating the `Error`, which is fragile and was starting to behave differently across Node versions. Replaced with straightforward string parsing of `new Error().stack`. **3. Removed the `console-stamp` dependency** - all formatting is now done with plain Node.js built-ins (`node:util` `styleText`). Same visual result, no external dependency. **4. Simplified the module wrapper** - the logger was wrapped in a UMD pattern, which is meant for environments like AMD/RequireJS. MagicMirror only runs in two places: Node.js and the browser. Replaced with a simple check (`typeof module !== "undefined"`), which is much easier to follow.
