xarmian cdbc69dd0e fix(editor): an empty mermaid block no longer shows "Rendering..." forever (BUG-3113) (#1414)
* fix(editor): an empty mermaid block no longer shows "Rendering..." forever (BUG-3113)

The mermaid NodeView seeded its diagram with a "Rendering..." placeholder
and queued a render only for non-empty source, so a block that was empty
when its view was built kept the placeholder with nothing coming to
replace it: a freshly typed fence, or an item loaded with an empty block.
The placeholder is now shown only when a render is actually queued; an
empty block stays empty, which is what update() already leaves when a
diagram's source is cleared.

e2e covers both entry paths, with a control block that must render an SVG
so "no placeholder" cannot pass because rendering is broken. Both paths
were red on the unfixed binary ("Rendering...") and are green on this one.

Pad Web UI

SvelteKit 2 + Svelte 5 frontend for Pad, compiled to static files and embedded into the Go binary.

Development

npm install
npm run dev          # Dev server at localhost:5173 (proxies API to localhost:7777)
npm run build        # Production build to build/
npm run check        # Type checking with svelte-check

When developing, run the Go backend separately with make dev from the project root.

Building for Production

Do not build in isolation. Always use make build from the project root — this builds the web frontend, then compiles the Go binary with the build output embedded via //go:embed.

Stack

  • Svelte 5 with runes ($state, $derived, $effect)
  • SvelteKit 2 with adapter-static (SPA mode)
  • Tiptap block editor with markdown round-trip
  • svelte-dnd-action for drag-and-drop in board/list views
  • SSE for real-time updates
  • TypeScript throughout
