Tiptap extension that intercepts paste/drop events with files, uploads
each through the attachment API, and replaces the placeholder with the
right node (attachmentImage for image MIMEs, attachmentChip for
everything else) at the position the user dropped.
The plugin's flow:
1. Detect file payloads in clipboardData.items / dataTransfer.files
(skip the event when there are none, so plain text paste / cursor
drag still go through tiptap-markdown's transformPastedText path).
2. Insert a position-tracked placeholder at the paste/drop position
via a setMeta transaction. Placeholders are widget decorations
(zero document width) so they never enter serialized markdown
even if the user navigates away mid-upload.
3. Race the network. The plugin's apply() handler maps every
placeholder position through every intervening transaction, so
continued editing doesn't strand the spinner.
4. On success: schema-aware replacement — attachmentImage for
category=image, attachmentChip otherwise. The placeholder is
removed in the same transaction.
5. On error: remove the placeholder and surface the failure via the
injected onError callback. The upload bytes that did land become
orphans; orphan-GC reclaims them after the grace period.
6. If the placeholder has been deleted before the upload completes
(user cancelled, navigated away, etc.) the upload is dropped
silently — same orphan-GC outcome.
Multiple files in a single drop fan out as concurrent uploads; each
gets its own placeholder and replaces independently as the network
completes.
Editor.svelte wires:
- upload -> api.attachments.upload(workspaceSlug, file)
(rejects with a clear message when no workspace context)
- onError -> console.error + window.alert as a minimal fallback
until a centralized toast system lands.
Styles (app.css) cover the placeholder bubble (dashed border, faded
colour) and a CSS spinner — kept inline via decoration widget DOM so
ProseMirror's selection ignores it (ignoreSelection: true).
Parent: PLAN-866. Closes the editor-input flow on top of TASK-874
(markdown resolver), TASK-876 (image node), TASK-877 (chip node).
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.
