# A Sembast Persistent Service for Angel3 [](https://pub.dartlang.org/packages/angel3_sembast) [](https://dart.dev/null-safety) [](https://gitter.im/angel_dart/discussion) [](https://github.com/dukefirehawk/angel/tree/angel3/packages/sembast/LICENSE) A plugin service that persist data to Sembast for Angel3 framework. ## Installation Add the following to your `pubspec.yaml`: ```yaml dependencies: angel3_sembast: ^2.0.0 ``` ## Usage This library exposes one main class: `SembastService`. ### SembastService This class interacts with a `Database` and `Store` (from `package:sembast`) and serializes data to and from Maps. ### Querying You can query these services as follows: ```dart /path/to/service?foo=bar ``` The above will query the database to find records where 'foo' equals 'bar'. The former will sort result in ascending order of creation, and so will the latter. ```dart List queried = await MyService.index({r"query": where.id(Finder(filter: Filter(...)))); ``` Of course, you can use `package:sembast` queries. Just pass it as `query` within `params`. See the tests for more usage examples.
