A live editor: token-themed CodeMirror in the code-block frame (type in it)

send.ts

8 lines · 278 chars. The ramp mirrors the CodeBlock canon (keywords, strings, numbers, comments), selection is the sanctioned soft wash, and the whole theme is var(--token)-driven. The island is live.

The web console’s editor panel is a real CodeMirror 6 instance whose entire look is the design system: the ground is a recessed well (fields sink), the caret and selection ride the accent (selection = the sanctioned soft wash, never an opaque brand fill), the gutter sits on the surface ramp, and the syntax ramp mirrors the Code block canon exactly. Keywords on accent-secondary, strings on status-success, functions on accent-tertiary, numbers on the categorical orange, comments muted italic. One code voice whether it’s read-only or live.

The chrome reuses the code-block header grammar verbatim: filename · LanguageBadge · the shared CopyButton (copying the live document). Focus reads on the panel (an inner accent outline), never a CodeMirror default.

The liftable deliverable

The design deliverable for the dashboard is nockerlCodeMirrorTheme() (_codeMirrorTheme.ts), an Extension[] built ONLY from var(--token) strings, so it theme-flips for free and never forks a hue. Web-only by scope; native surfaces read code through the cross-platform CodeBlock.

Code

import { EditorView, lineNumbers } from '@codemirror/view';
import { EditorState } from '@codemirror/state';
import { javascript } from '@codemirror/lang-javascript';
import { nockerlCodeMirrorTheme } from './_codeMirrorTheme';

new EditorView({
  parent: host,
  state: EditorState.create({
    doc: source,
    extensions: [lineNumbers(), javascript({ typescript: true }), nockerlCodeMirrorTheme()],
  }),
});
