PowerSync offline-first sync engine on SQLite for React Native - schema definition, watched queries, CRUD operations, backend connectors, sync rules, conflict resolution, attachments.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# SQLite + PowerSync Patterns
> **Quick Guide:** Use `@powersync/react-native` for offline-first apps backed by local SQLite. Define schemas with `Table` and `column.text/integer/real` (id column is auto-created). Use `PowerSyncDatabase` for reads/writes, `useQuery` from `@powersync/react` for reactive watched queries. Connect to your backend via a connector implementing `fetchCredentials` + `uploadData`. Conflict resolution defaults to last-write-wins per field -- customize in `uploadData`. Use `@powersync/op-sqlite` for SQLCipher encryption.

## CRITICAL: Before Using This Skill
**(You MUST define schemas with `new Table({ ... })` using `column.text`, `column.integer`, `column.real` -- NEVER declare an `id` column, PowerSync creates it automatically)**
**(You MUST call `powersync.connect(connector)` after `init()` to start syncing -- without it the database is local-only with no sync)**
**(You MUST implement both `fetchCredentials()` and `uploadData()` in your backend connector -- missing either breaks the sync loop)**
**(You MUST use `useQuery` from `@powersync/react` for reactive queries -- raw `getAll()` does NOT re-render on data changes)**

How to install
mdr add agents-inc/skills/mobile-storage-sqlite-powersync@sha256:7d875c66503d5deeThe line at the top of this page pins the label git:20261016.afd0e14, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
