- Detail screen: Delete button (top-right, red) with confirmation alert;
deletes SQLite row and original file via expo-file-system
- Feed screen: long-press card to enter select mode; checkbox + blue
border on selected cards; bottom action bar with bulk Delete N button;
header switches to show count + Cancel
- db/queries: deleteActivity (returns original_path) and deleteActivities
(bulk, returns all original paths)
In Hermes release builds, useEffect captures closure values from the first
render. If instanceUrl or token were empty at that moment (before SQLite reads
complete), no fetch ran and map/graphs never loaded. Adding them to the
dependency array ensures the effect re-runs once the values are available;
guards on existing geojson/timeseries state prevent double-fetching.
Also add @maplibre/maplibre-react-native to the Expo plugins array so that
expo prebuild applies the library's required Gradle property configuration to
the Android project.
Android release builds block cleartext HTTP by default (debug builds override
this via the debug manifest overlay). Add usesCleartextTraffic=true to app.json
so expo prebuild includes it in the generated manifest — required to reach local
Bincio instances over HTTP.
In bincio dev (Astro dev server), /activity/<id>/ routes 404 because
getStaticPaths() returns [] and there is no nginx try_files fallback. Add a Vite
middleware plugin to astro.config.mjs that rewrites /activity/<id>/ to /activity/
in dev, matching what nginx does in production.
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
