Add your description here

dr_widget

dr_widget is a hybrid Python/Svelte project for building reusable AnyWidget components that can be dropped into Marimo notebooks today and exported to full Svelte apps later. The repository currently ships a file-drop configuration browser, but the layout is designed to host additional widgets.

Quick Start

# Install JS dependencies (root + workspace)
bun install

# Live-reload the file-drop widget in a browser
bun run dev:file-drop

# Produce the optimized bundle used by AnyWidget
bun run build

# Build the Python distributions (wheel + sdist)
uv build

# Launch the Marimo demo notebook
marimo run notebooks/file_widget.py

Prerequisites: Bun ≥ 1.0, Node-compatible environment, Python ≥ 3.11 with uv, and Marimo ≥ 0.17.6.

Repository Layout

• src/dr_widget/ – Python package exposing AnyWidget classes.
  • widgets/file_drop/ – widget workspace (Svelte source in src/, build output in static/).
    • src/FileDropWidget.svelte – orchestration layer wiring bindings into the panel components.
    • src/lib/hooks/use-file-bindings.ts – shared logic for syncing AnyWidget traitlets.
    • src/lib/components/ – shadcn-style UI primitives and file-drop panels, including a config viewer card with both a tree view and graph view for JSON payloads.
• docs/ – additional reference material (architecture, development workflows).
• notebooks/file_widget.py – Marimo notebook that exercises the file-drop widget.

Documentation

• Architecture Overview – how Python, AnyWidget, and Svelte fit together.
• Development Workflow – commands for widget builds, packaging, and notebooks.
• Repository Guidelines – coding standards, contracts, and contribution checklist.

Contributing

1. Work inside a dedicated branch.
2. Run bun run build, npx svelte-check, and uv build before opening a PR.
3. Update the notebook and docs when you add or change widget behaviour.
4. Follow the commit and PR practices outlined in AGENTS.md.

Please open an issue if you hit build problems or want to discuss new widgets.
