| # rxjdbc | ||
|
|
||
| <a href="https://github.com/davidmoten/rxjava-jdbc">rxjava-jdbc</a> efficient execution, concise code, and functional composition of database calls using JDBC and RxJava Observable. | ||
|
|
||
| This module depends on [jdbc module](/doc/jdbc), make sure you read the doc of the [jdbc module](/doc/jdbc) module. | ||
|
|
||
| ## dependency | ||
|
|
||
| ```xml | ||
| <dependency> | ||
| <groupId>org.jooby</groupId> | ||
| <artifactId>jooby-rxjdbc</artifactId> | ||
| <version>1.0.0.CR2</version> | ||
| </dependency> | ||
| ``` | ||
|
|
||
| ## exports | ||
|
|
||
| * A ```Database``` object | ||
| * A [Hikari](https://github.com/brettwooldridge/HikariCP) ```DataSource``` object | ||
|
|
||
| ## usage | ||
|
|
||
| ```java | ||
| import org.jooby.rx.RxJdbc; | ||
| import org.jooby.rx.Rx; | ||
| { | ||
| use(new RxJdbc()); | ||
|
|
||
| get("/reactive", req -> | ||
| req.require(Database.class) | ||
| .select("select name from something where id = :id") | ||
| .parameter("id", 1) | ||
| .getAs(String.class) | ||
| ).map(Rx.rx()); | ||
|
|
||
| } | ||
| ``` | ||
|
|
||
| The [Rx.rx()](/apidocs/org/jooby/rx/Rx.html#rx--) mapper converts ```Observable``` to [deferred](/apidocs/org/jooby/Deferred.html) instances. More at [rx module](/doc/rxjava). | ||
|
|
||
| ## multiple db connections | ||
|
|
||
| ```java | ||
| import org.jooby.rx.RxJdbc; | ||
| import org.jooby.rx.Rx; | ||
| { | ||
| use(new RxJdbc("db.main")); | ||
|
|
||
| use(new RxJdbc("db.audit")); | ||
|
|
||
| get("/", req -> | ||
|
|
||
| Databse db = req.require("db.main", Database.class); | ||
| Databse audit = req.require("db.audit", Database.class); | ||
| // ... | ||
| ).map(Rx.rx()); | ||
|
|
||
| } | ||
| ``` | ||
|
|
||
| For more details on how to configure the Hikari datasource, please check the [jdbc module](/doc/jdbc). | ||

||
| Happy coding!!! |
