# angel_mongo
![version 1.0.0-dev+5](https://img.shields.io/badge/version-1.0.0--dev+5-red.svg)
![build status](https://travis-ci.org/angel-dart/mongo.svg?branch=master)
MongoDB-enabled services for the Angel framework.
# Installation
Add the following to your `pubspec.yaml`:
```yaml
dependencies:
angel_mongo: ^1.0.0-dev
```
# Usage
This library exposes three main classes: `Model`, `MongoService` and `MongoTypedService<T>`.
## Model
`Model` is class with no real functionality; however, it represents a basic MongoDB document, and your services should host inherited classes.
```dart
class User extends Model {
String username;
String password;
}
main() async {
Db db = new Db('mongodb://localhost:27017/local');
await db.open();
app.use('/api/users', new MongoTypedService<User>(db.collection("users")));
app.service('api/users').afterCreated.listen((event) {
print("New user: ${event.result}");
});
}
```
## MongoService
This class interacts with a `DbCollection` (from mongo_dart) and serializing data to and from Maps.
## MongoTypedService<T>
Does the same as above, but serializes to and from a target class using json_god and its support for reflection.
## Querying
You can query these services as follows:
/path/to/service?foo=bar
The above will query the database to find records where 'foo' equals 'bar'. Thanks to body_parser, this
also works with numbers, and even Maps.
/path/to/service?$sort=createdAt
/path/to/service?$sort.createdAt=1
The former will sort result in ascending order of creation, and so will the latter.
List queried = await MyService.index({r"$query": where.id(new ObjectId.fromHexString("some hex string"})));
And, of course, you can use mongo_dart queries. Just pass it as `query` within `params`.
See the tests for more usage examples.
