## Status

This project is used in production at Twitter (and many other organizations),

and is being actively developed and maintained.



Finatra is a lightweight framework for building fast, testable, scala applications on top of [TwitterServer][twitter-server] and [Finagle][finagle]. Finatra provides an easy-to-use API for creating and [testing](https://twitter.github.io/finatra/user-guide/testing/index.html) [Finagle servers](https://twitter.github.io/finagle/guide/Servers.html) and [apps](https://twitter.github.io/util/docs/#com.twitter.app.App) as well as powerful JSON support, modern logging via [SLF4J][slf4j], [Finagle client](https://twitter.github.io/finagle/guide/Clients.html) utilities, and more.

## Getting involved

## Features

* Production use [@Twitter](https://twitter.com/).

* ~50 times faster than v1.6 in several benchmarks.

* Powerful Feature and Integration test support.

* Optional JSR-330 Dependency Injection using [Google Guice][guice].

* [Jackson][jackson]-based JSON parsing supporting required fields, default values, and [validations](https://twitter.github.io/finatra/user-guide/json/validations.html).

* [Logback][logback] [MDC][mdc] integration with [com.twitter.util.Local][local] for contextual logging across [futures](https://twitter.github.io/util/guide/util-cookbook/futures.html).

## Documentation

To get started, see the [Getting Started](https://twitter.github.io/finatra/user-guide/index.html#getting-started) section of our [User Guide][user-guide] to get up and running. Or check out the specific sections for building [HTTP](https://twitter.github.io/finatra/user-guide/http/server.html) or [Thrift](https://twitter.github.io/finatra/user-guide/thrift/server.html) servers.

## Examples

An HTTP controller and server:

```scala

import com.twitter.finatra.http._

@Singleton

class ExampleController extends Controller {

  get("/") { request: Request =>

    "
Hello, world!"

  }

}

```

```scala

import com.twitter.finatra.http._

class ExampleServer extends HttpServer {

  override def configureHttp(router: HttpRouter): Unit = {

    router

      .filter[CommonFilters]

      .add[ExampleController]

  }

}

```

A Thrift controller and server:

```scala

import com.twitter.finatra.thrift._

import com.twitter.scrooge.{Request, Response}

@Singleton

class ExampleThriftController

  extends Controller(MyThriftService) {

  handle(MyFunction).withFn { request: Request[MyFunction.Args] =>

    ...

  }

}

```

```scala

import com.twitter.finatra.thrift._

class ExampleServer extends ThriftServer {

  override def configureThrift(router: ThriftRouter): Unit = {

    router

      .add[ExampleThriftController]

  }

}

```

## Example Projects

Finatra includes working examples which highlight various features of the framework and include tests. These examples are included in the root [sbt][sbt] build and are thus buildable as part of the entire project.

Please take a look through the [examples](/examples) for more detailed information on features, testing, building, and running.
