The editor was overflowing its container because @uiw/react-codemirror
renders a wrapper div that doesn't inherit flex constraints by default.
Fixed by adding CSS rules that:
1. Set overflow:hidden on .cm-editor-container
2. Target the wrapper div (> div) with flex:1, min-height:0, overflow:hidden
3. Set .cm-editor and .cm-scroller to overflow appropriately
This ensures the flex height constraint propagates through every level
of the CodeMirror DOM tree, and only .cm-scroller scrolls.
Layout chain:
.cm-editor-container (flex-1, min-h-0)
└─ wrapper div (flex:1, min-h-0, overflow:hidden)
└─ .cm-editor (flex:1, min-h-0, overflow:hidden)
└─ .cm-scroller (min-h-0, overflow:auto) ← only this scrolls
react-ace v14 is CommonJS-only with no ESM entry point, making it
fundamentally incompatible with Vite's ESM-first dev server. Every
CJS interop workaround failed. Switched to @uiw/react-codemirror v4.25
which ships proper dual ESM+CJS and works with Vite out of the box.
Changes:
- Remove ace-builds and react-ace dependencies
- Add @uiw/react-codemirror + 16 @codemirror/lang-* packages
- Add @uiw/codemirror-theme-tomorrow-night-blue (closest to ACE's 'tomorrow')
- Add @replit/codemirror-lang-csharp for C# support
- Rewrite EditorPanel.tsx: delete 108 lines of ACE boilerplate
(?url imports, setModuleUrl, CJS interop hack), replace with
~30 lines of clean CodeMirror language extension setup
- Delete vite.d.ts (only needed for ACE ?url import types)
- Remove optimizeDeps.include from vite.config.ts (not needed for CM)
- Add CodeMirror flex layout CSS to index.css
Supported languages: JavaScript/JSX, TypeScript/TSX, Python, JSON,
HTML, CSS, Less, YAML, Markdown, SQL, Java, Go, Rust, C/C++, C#,
PHP, XML. Unsupported types fall back to plain text.
Verified: tsc clean, vite build passes, heartbeat worker intact.
The Chat View area of the view was growing in width (unbounded), and has
been fixed. From the agent:
> The root cause was a flexbox sizing rule: in ChatSessionView.tsx:768
the parent row flex-1 flex bg-bg-primary overflow-hidden relative has
two children — the content area and the sidebar. The content area (line
777) was flex-1 flex flex-col relative, which as a flex child defaults
to min-width: auto. This means its intrinsic content width (driven by
the wide <pre>) is used as a minimum, forcing the flex item to expand
the whole row beyond the viewport.
>
> Adding min-w-0 overrides min-width: auto to min-width: 0, letting the
flex item shrink below its content's natural width. Now the
overflow-x-auto on the markdown wrapper actually has somewhere to scroll
into.
