Instructions for Claude Code when working on this project.
|
|
|
|
## Project Overview
|
|
|
|
**Astrolabe** is a lightweight, browser-based snippet manager for Vega-Lite visualizations. Pure vanilla JavaScript, no build tools, retro Windows 2000 aesthetic.
|
|
|
|
## Architecture
|
|
|
|
- **Frontend-only**: HTML/CSS/JavaScript with CDN dependencies (Monaco Editor, Vega-Embed)
|
|
- **Storage**:
|
|
- **Snippets**: localStorage with Phase 0 schema (id, name, created, modified, spec, draftSpec, comment, tags, datasetRefs, meta)
|
|
- **Datasets**: IndexedDB (unlimited size, multi-format: JSON/CSV/TSV/TopoJSON, inline & URL sources)
|
|
- **Structure**: Three resizable panels (snippet library, Monaco editor, live preview) + Dataset Manager modal
|
|
- **No build tools**: Open `index.html` directly in browser (needs local server for IndexedDB)
|
|
|
|
## Current Status
|
|
|
|
**Completed**: Phases 0-10 (Core functionality + Dataset Management)
|
|
**Next**: Phase 11 - Advanced Dataset Features (optional enhancements)
|
|
|
|
