Changelog

v1.8.2

  • [IMPROVED] Deprecated the rawTableNames option in SQLWatchOptions. All tables specified in the tables option will now be watched, including PowerSync tables with prefixes.

v1.8.1

  • [FIXED] An issue where sequentially mutating the same row multiple times could cause the CRUD upload queue monitoring to think CRUD operations have not been processed correctly by the BackendConnector uploadData method. See details in this PR.

v1.8.0

  • [ADDED] UMD distribution to introduce react-native-web support (available under @powersync/web/umd). Learn more here.

  • [IMPROVED] DB and sync workers instantiation can now be overriden with a path or a factory method.

  • [IMPROVED] Removed lodash dependency.

v1.7.0

Note: Some features in this version require journeyapps/powersync-service v0.5.0 or later when self-hosting.

This version updates powersync-sqlite-core to version 0.2.0 and introduces:

  • [ADDED] Custom User-Agent header and client_id parameter to sync requests.

  • [ADDED] Emit update notifications for watch queries on disconnectAndClear().

  • [IMPROVED] Sync optimizations for MOVE and REMOVE operations. See details in this PR.

  • [IMPROVED]SyncStatus.lastSyncedAt now returns a persisted timestamp of the last synced at time (previously it reset after a restart).

  • [IMPROVED] Validate that the powersync-sqlite-core version number is in a compatible range of ^0.2.0.

  • [IMPROVED] Always cast target_op (write checkpoints) to ensure it's an integer.

Additionally:

  • [IMPROVED] Merge Table and TableV2 definitions but kept TableV2 to avoid making this a breaking change. Find details in this PR.

  • [FIXED] SSR Mode detection for DB adapters. Removed the potential for SSR Web Streaming implementations to perform syncing operations. More details in the PR.

v1.6.0

  • [IMPROVED] Significantly improved performance in syncing large data sets (e.g. initial syncs) by debouncing update notifications [PR].

  • [IMPROVED] WebSocket streaming is now the default connection method. HTTP streaming can still be specified if desired.

  • [IMPROVED] Added basic validations for required options in PowerSyncDatabase constructor (useful for JavaScript).

  • [INTERNAL] Updated the internals of deleteBucket to use a simpler action.

v1.5.1

  • [FIXED] An issue where the shared sync manager would not discard stale credentials.

  • [FIXED] hasSynced status now resets correctly after disconnectAndClear has been called.

v1.5.0

  • [IMPROVED] Added a warning if connector uploadData functions don't process CRUD items completely [PR].

v1.4.0

  • [IMPROVED] Polyfills are now prebundled into the SDK, requiring one less polyfill when using WebSockets.

v1.3.0

  • [ADDED] debugMode flag to log queries on the Developer Tools performance timeline [PR].

v1.2.1

  • [IMPROVED] Transactions that are reporting on failed rollback exceptions are now silenced when they are safe to ignore.

v1.2.0

v1.1.0

v1.0.2

  • Updated dependencies:

  • This SDK is now in a stable release

  • Updated dependencies:

    • [ADDED] A mechanism for throttling watch callback executions.

v0.7.0

  • [IMPROVED] The import and usage of the BSON library.

v0.6.1

  • Updated dependencies:

    • [FIXED] An issue with Vite not being able to resolve Sourcemaps by introducing a tsconfig.base file in the root of the repo.

v0.6.0

  • [ADDED] Support for WebSocket sync stream connections. Learn more here.

  • Updated dependencies:

    • [IMPROVED] Removed the uuid dependency.

v0.5.3

    • [FIXED] hasSynced to also change when there is no data on app load.

v0.5.2

  • Updated dependencies:

    • [IMPROVED] Allow compilable queries to be used as hook arguments so that queries from an ORM can be used.

    • [FIXED]disconnectAndClear() not clearing ps_untyped records.

    • [FIXED] Incorrect type of Schema.tables.

v0.5.1

  • [IMRPOVED] Renamed the package from @journeyapps/powersync- to @powersync/. The @journeyapps/powersync-sdk-web package is deprecated and the renamed package is published here: https://www.npmjs.com/package/@powersync/web

  • Updated dependencies:

    • [FIXED] Default onError callback for watch() and onChange() that used an unbounded member.

v0.5.0

  • Updated dependencies:

    • [ADDED] Support for Full-text search and enabled recursive triggers.

v0.4.1

  • Updated dependencies:

    • [ADDED]hasSynced property to SyncStatus. This value is managed in AbstractPowerSyncDatabase, and becomes true after the first sync has completed.

    • [ADDED] Added waitForFirstSync method to allow users to await on the state change of hasSynced to true.

    • [FIXED] Resolving tables for watch() before handling any results, eliminating a potential race condition between initial results and updates.

    • [FIXED] Also handled a potential uncaught exception.

v0.4.0

  • [ADDED] The ability to disable broadcast logging in WebPowerSyncFlags.

  • [FIXED] Shared sync broadcast logger sanitization and error handling.

  • Updated dependencies:

    • [ADDED] Added executeBatch method. This allows a SQL statement with multiple parameters to be executed in a single transaction, improving performance and consistency.

v0.3.3

  • Updated dependencies:

    • [IMPROVED] Introduced overloaded versions of the watch and onChange methods to support a callback approach to handle results and errors alongside the existing AsyncGenerator mechanism.

v0.3.2

  • [IMPROVED] Minor code cleanup for the shared sync worker.

  • Updated dependencies:

    • [FIXED] A regression where watched queries would update for table changes in external (not in query) tables.

v0.3.1

  • [IMPROVED] Added some serialization checks for broadcasted logs from the shared web worker. Unserializable items will now return a warning.

  • [FIXED] An issue where SyncBucketStorage logs would not be broadcasted from the shared sync worker to individual tabs.

  • Updated dependencies:

    • [FIXED] An issue where sync stream exceptions would not close previous streaming connections.

    • [IMPROVED] Reduced JS bundle size.

    • [ADDED] equals method on CrudEntry class to better align comparison operations with JavaScript.

    • [IMPROVED] AbstractPowerSyncDatabase.getCrudBatch now use a getAll instead of using database.execute.

    • [FIXED] Minor bugs in BucketStorage adapter.

    • [FIXED] Removed object-hash package as a dependency as this caused issues with Next.js 14.1.0.

  • Updated dependencies:

    • [FIXED] Missing transactionId value in the response of getNextCrudTransaction.

v0.2.0

  • Updated dependencies:

    • [ADDED] viewName option to Schema Table definitions. This allows for overriding a table's view name, which allows having separate tables for a synced mode and a local-only mode, and moving data between the two.

    • [IMPROVED] Table change updates to be throttled on the trailing edge. This prevents unnecessary query on both the leading and rising edge.

v0.1.3

  • [FIXED] Watched queries not updating due to race condition when opening multiple WA-SQLite connections due to initiating multiple PowerSync instances simultaneously.

v0.1.2

  • Updated dependencies:

    • [IMPROVED] Connector CRUD uploads will now be triggered whenever an internal CRUD operation change is triggered.

    • [IMPROVED] CRUD upload debouncing will now rather use a throttled approach - executing multiple continuous write/CRUD operations will now trigger a connector upload at most (every) 1 second (by default).

  • [FIXED] A bug where opening multiple WA-SQLite instances to the same DB could break watched queries. This issue could arise when using multiple tabs or when opening multiple PowerSync instances for the same DB (e.g when initializing PowerSync in React strict mode under some circumstances).

v0.1.1

  • [ADDED] Two example projects:

  • [IMPROVED] Introduced a new pnpm format script to correctly format corresponding files with prettier.
