### Automated generation of [Finagle](https://twitter.github.io/finagle/) HTTP/JSON services and [Swagger UI](https://swagger.io/tools/swagger-ui/) from [Thrift](https://thrift.apache.org/) service definitions. | ||
|
||
------ | ||
|
||
## Purpose | ||
|
||
Provide a quick and human-friendly way of discovering and trying out Thrift APIs, without having to compile Thrift clients for your services. | ||
With **kara**, all your Thrift APIs can benefit from Swagger UI, where schema is exposed, and requests can be tried. | ||
|
||
And since a HTTP/JSON API is exposed, you don't necessarily have to deal with the Swagger UI to interact with your Thrift services: you can use your favourite tools (e.g. `curl`, [Postman](https://www.postman.com/)) or anything that talks HTTP/JSON, really! | ||
|
||
**NOTE**: while extremely useful during development, **kara** is not intended for production use. | ||
|
||
## Usage | ||
|
||
- Add **kara** as a plugin to the sbt project adding a line containing `addSbtPlugin("com.ea" % "kara" % "0.1.0")` in `project/plugins.sbt`. | ||
- In your project settings in `build.sbt`: | ||
- configure `karaServices = Seq("fully_qualified_service_1", "fully_qualified_service_2, ...)` to indicate the Thrift services Kara should generate Finagle services and Swagger UI for. Services should be listed in `<JAVA_NAMESPACE>.<SERVICE_NAME>` format. | ||
- enable the the plugin with `.enablePlugins(Kara)` on the project that lists the Thrift sources and on which `ScroogeSBT` is enabled. | ||
|
||
On compilation (`sbt compile`), a Finagle HTTP service named `Http<SERVICE_NAME>` is generated, which takes as input an instance of a [Scrooge](http://twitter.github.io/scrooge/)-generated Thrift service `<SERVICE_NAME>.MethodPerEndpoint`. All is left to do is to instantiate it in your app and bind it to a Finagle server on a port of your choice. | ||
|
||
## Example | ||
|
||
#### project/plugins.sbt | ||
|
||
```scala | ||
addSbtPlugin("com.ea" % "kara" % "0.1.0") | ||
``` | ||
|
||
#### build.sbt | ||
|
||
```scala | ||
// ... | ||
|
||
lazy val thrift = project.in(file("thrift")) | ||
.settings( | ||
// ... | ||
karaServices := Seq("path.to.Service1", "path.to.Service2") | ||
).enablePlugins(Kara) | ||
|
||
// ... | ||
``` | ||
|
||
#### App.scala | ||
|
||
```scala | ||
import com.twitter.finagle.Http | ||
|
||
// ... | ||
|
||
val thriftSvc: Service1.MethodPerEndpoint = ??? | ||
val karaSvc: HttpService1 = new HttpExampleService1(thriftSvc) | ||
Http.server.serve(":8080", karaSvc) | ||
|
||
// ... | ||
``` | ||
|
||
[Scripted tests](./src/sbt-test/kara/) are a great way to see **kara** in action. | ||
|
||
## Swagger UI | ||
|
||
`kara` v.`0.1.0` employs Swagger UI v`.3.31.1`. | ||
|
||
## Testing | ||
|
||
**kara** features two modes of testing: | ||
- *Unit tests*, testing code generation logic: | ||
- `sbt test` | ||
- *E2E tests*, testing plugin functionality via [scripted](https://www.scala-sbt.org/1.x/docs/Testing-sbt-plugins.html) test framework: | ||
- `sbt scripted` | ||
|
||
## Developer | ||
|
||
**kara** was born at [EA DICE](https://www.dice.se/). | ||
