micropip requires the full PEP 427 wheel filename (name-version-py-abi-plat.whl)
— writing the file as bincio.whl caused InvalidWheelFilename. The wheel URL from
/api/wheel/version now provides the basename; it flows through fetchWheelBase64 →
extractFile → WebView where the file is written with the correct name and
_wheel_path is set as a Pyodide global before PY_INSTALL_WHEEL runs.
Layout fix: WebView as a sibling in the root layout breaks flex geometry even
with position:absolute. Moving it inside the Import tab screen (which Expo Router
keeps mounted after first visit) eliminates the issue entirely and restores the
original simple root layout.
micropip fix: blob: URLs are not a recognised scheme in micropip — they are parsed
as package requirement strings, producing InvalidRequirement. Write the wheel bytes
to Pyodide's Emscripten FS (/tmp/bincio.whl) and install via emfs:/// instead.
WKWebView blocks HTTP requests (ATS) even when NSAllowsLocalNetworking is set for
the app's own networking — so fetch(http://192.168.x.x/api/wheel/download) inside
the WebView always fails with 'Load failed' on iOS.
- extractActivity.ts: rename wheelUrl param to wheelBase64; WebView now receives
the wheel as pre-fetched base64 bytes rather than a URL to fetch itself
- PyodideWebView.tsx: decode wheelBase64 → Uint8Array → Blob → blob URL for
micropip.install; fix baseUrl '' → 'https://localhost' (null origin blocks fetch
on iOS)
- import.tsx: add fetchWheelBase64() that resolves the wheel URL via
/api/wheel/version then fetches with native networking (HTTP works); caches
result in memory so repeated imports in one session don't re-download
- extraction/PyodideWebView.tsx: hidden WebView (1×1 px, off-screen) that
bootstraps Pyodide v0.26.4 from jsDelivr CDN on app startup; loads lxml,
pyyaml, micropip, fitdecode, gpxpy automatically; installs the bincio wheel
lazily on the first extraction call via a blob URL (avoids startup delay)
- extraction/extractActivity.ts: typed bridge — extractFile(filename, base64,
wheelUrl, onStatus) injects JS into the WebView, tracks pending promises by
request ID, resolves with { id, detail, timeseries, geojson, sourceHash }
- app/_layout.tsx: mounts <PyodideWebView> outside SQLiteProvider at root so
the runtime warms up as soon as the app opens
- app/(tabs)/import.tsx: replaces the placeholder alert with real extraction;
reads files as base64, calls extractFile with a progress callback, stores
detail_json + timeseries_json + geojson + real SHA-256 source_hash; resolves
wheel URL via GET /api/wheel/version with fallback to /api/wheel/download;
falls back to bincio.org if no instance is configured
- Server: POST /api/upload/bas accepts pre-extracted BAS JSON (activity + optional timeseries/geojson), writes files and triggers merge_all
- sync.ts: uploadLocalActivities reads unsynced local activities by original_path, POSTs to /api/upload/bas, marks synced_at on success
- Settings: Upload toggle (Off / Upload local activities) in Sync section with subLabel dividers for Download / Upload groups
- Feed: sync message includes uploaded count when activities are pushed
- Add /api/activity/{id}/geojson and /api/activity/{id}/timeseries endpoints
(bearer-token-gated, falls back from _merged to raw activities dir)
- Rewrite activity detail screen with MapLibreGL v11 API (Map, Camera,
GeoJSONSource, Layer) and react-native-svg area chart with gradient fill
- On-demand fetch for remote activities that have no local geojson/timeseries
- Add react-native-svg dependency; requires dev build (npx expo run:android)
_merged/index.json is a shard manifest with activities:[] when the user
has >FEED_PAGE_SIZE activities. The endpoint now collects from all
index-{year}.json shard files before returning.
SyncResult gains a `total` field (activities received from server) so the
feed screen can distinguish "server returned nothing" from "all already
stored locally". Messages: "No activities on instance" / "Up to date (N)"
/ "X of N activities synced".
Server (bincio/serve/server.py):
- Add _require_auth: accepts session cookie OR Authorization: Bearer token
- POST /api/auth/token: same as /api/auth/login but returns token in body
(password used once, not stored; mobile stores only the session token)
- GET /api/feed: auth-gated; reads _merged/index.json for the user and
returns the activities array as JSON
Mobile:
- db/sync.ts: syncFeed(db) fetches /api/feed, upserts each summary into
local SQLite as origin='remote'; skips locally-imported activities
- db/queries.ts: add upsertRemoteActivity (INSERT ... ON CONFLICT DO UPDATE
WHERE origin='remote' — never overwrites local imports); fix feed sort
order to started_at DESC instead of insertion order
- settings.tsx: Connect section — password field (not persisted) + Connect
button calls POST /api/auth/token and stores token; Disconnect clears it
- index.tsx: ↓ Sync button + pull-to-refresh both trigger syncFeed; cloud
badge on remote activities; empty state updated
expo-router@6.0.23 declares react-dom as peerOptional; without an explicit
pin npm resolves react-dom@19.2.5 (latest) which conflicts with react@19.1.0.
The SDK 54 template pins both to 19.1.0 — mirroring that here.
react-dom@19.2.5 (pulled by @expo/router-server) requires react@^19.2.5;
@react-native/virtualized-lists@0.85.2 requires @types/react@^19.2.0.
npm install now completes without errors or warnings.
- Add GET /api/wheel/download to serve/server.py and edit/server.py:
serves dist/bincio-*.whl via FileResponse; in production nginx takes
the request before FastAPI, so this is a no-op there but works locally
- wheel_version response now includes api_url: "/api/wheel/download"
alongside the nginx-served url field
- Bundle mobile/assets/bincio.whl (built from dist/) as an offline
fallback for Pyodide testing before the first instance sync
- docs/mobile-app.md: document dev setup — bundled asset, local server
endpoint, and how to refresh the bundle with uv build + cp
