Node source (Python) and the JSON dialog share one CodeMirror editor with
find and replace, autocomplete, folding, indent guides, comment toggle and a
JSON lint, themed from the CSS tokens so light and dark follow the .dark class
without a second palette. Programmatic value changes no longer fire onChange,
blur ignores focus moving into the find bar, readOnly keeps selection and copy.
The editor chunk is 470 kB (157 kB gzipped) against 2.7 MB (704 kB) for Monaco,
which also pulled in a 1.2 MB JSON mode, two workers and a font. At 4x CPU on
slow 4G a node panel is ready in 5.7 s instead of 10.8 s, the JSON dialog in
1.5 s instead of 6.7 s. Typing without a key delay keeps every character.
monaco-editor, @monaco-editor/react and the dompurify override are removed.
Specs: typed code reaches the node source, a JSON setting saves only text that
parses. Docs name Tab and Ctrl-M.
The backend image now builds the SPA and serves it on the API's own origin
(fluksio/spa.py), so an instance is a single container with no proxy, DNS,
port 80 or .env: `docker compose up -d` with the new compose.yml runs it on
localhost:8080. It starts on fluksio serve (persisted secret key, first
admin printed once) and brings its own Redis when REDIS_HOST is unset.
Slimmer: python:3.13-slim, no dev group, uv once, fastapi without the cloud
CLI. Optional features are per-feature extras (mqtt, influx, email, sentry,
ml, server for all) picked with the EXTRAS build argument; numpy moved to
`ml`. ffmpeg left the image for imageio-ffmpeg via the Modules screen.
The operator stack runs the same image with app. and api. routed to it; the
nginx frontend service, the LAN nginx proxy and DOMAIN in the backend are
gone, and the MCP issuer is FRONTEND_HOST.
