leaflet_svelte

Weather-balloon trajectory planner. Static SvelteKit SPA that talks to a Django REST backend.

Quick start

npm install

# dev against a local Django on :8000 (see .env.example)
npm run dev

# dev with a fake backend (no Django needed)
VITE_USE_MOCK_API=true npm run dev

# type-check + production build (emits static files to ./build)
npm run check
npm run build

Serve build/ from any static host. Route fallback is index.html.

Documentation

• docs/ARCHITECTURE.md — module layout and data flow.
• docs/CONVENTIONS.md — naming, styling, component patterns.
• docs/ADDING_A_FEATURE.md — walkthrough for adding a new panel/feature.
• mocks/ — Vite dev-server mock backend.

Stack

• SvelteKit + Vite (TypeScript, Svelte 5 runes) — built as a pure SPA with @sveltejs/adapter-static.
• MapLibre GL JS via the $map abstraction — the app never imports maplibre-gl directly outside src/lib/map/.
• Sveltestrap + Bootstrap 5 for UI chrome.
• Chart.js for the ascent/descent profile editor.
• @vincjo/datatables for editor tables.
