bootstrap-play-26

This library implements basic functionality required by the platform frontend/microservices.

Adding to your build

In your SBT build add:

resolvers += Resolver.bintrayRepo("hmrc", "releases")

libraryDependencies += "uk.gov.hmrc" %% "bootstrap-play-26" % "x.x.x"

Configure as a frontend microservice

In your application.conf file, add:

# An ApplicationLoader that uses Guice to bootstrap the application.
play.application.loader = "uk.gov.hmrc.play.bootstrap.ApplicationLoader"

# Primary entry point for all HTTP requests on Play applications
play.http.requestHandler = "uk.gov.hmrc.play.bootstrap.http.RequestHandler"

# Provides an implementation of AuditConnector. Use `uk.gov.hmrc.play.bootstrap.AuditModule` or create your own.
# An audit connector must be provided.
play.modules.enabled += "uk.gov.hmrc.play.bootstrap.AuditModule"

# Provides an implementation of MetricsFilter. Use `uk.gov.hmrc.play.bootstrap.graphite.GraphiteMetricsModule` or create your own.
# A metric filter must be provided
play.modules.enabled += "uk.gov.hmrc.play.bootstrap.graphite.GraphiteMetricsModule"

# Provides an implementation and configures all filters required by a Platform frontend microservice.
play.modules.enabled += "uk.gov.hmrc.play.bootstrap.FrontendModule"
play.http.filters = "uk.gov.hmrc.play.bootstrap.filters.FrontendFilters"

And in your SBT build add:

libraryDependencies += "uk.gov.hmrc" %% "play-ui" % "x.x.x"
libraryDependencies += "uk.gov.hmrc" %% "govuk-template" % "x.x.x"

Configure as a backend microservice

In your application.conf file, add:

# An ApplicationLoader that uses Guice to bootstrap the application.
play.application.loader = "uk.gov.hmrc.play.bootstrap.ApplicationLoader"

# Primary entry point for all HTTP requests on Play applications
play.http.requestHandler = "uk.gov.hmrc.play.bootstrap.http.RequestHandler"

# Provides an implementation of AuditConnector. Use `uk.gov.hmrc.play.bootstrap.AuditModule` or create your own.
# An audit connector must be provided.
play.modules.enabled += "uk.gov.hmrc.play.bootstrap.AuditModule"

# Provides an implementation of MetricsFilter. Use `uk.gov.hmrc.play.bootstrap.graphite.GraphiteMetricsModule` or create your own.
# A metric filter must be provided
play.modules.enabled += "uk.gov.hmrc.play.bootstrap.graphite.GraphiteMetricsModule"

# Provides an implementation and configures all filters required by a Platform frontend microservice.
play.modules.enabled += "uk.gov.hmrc.play.bootstrap.MicroserviceModule"
play.http.filters = "uk.gov.hmrc.play.bootstrap.filters.MicroserviceFilters"

Default HTTP client

A default http client with pre-configured auditing hook can be injected into any connector. The http client uses http-verbs For more http-verbs examples see https://github.com/hmrc/http-verbs-example

Make sure you have the following modules in your application.conf file:

play.modules.enabled += "uk.gov.hmrc.play.bootstrap.AuditModule"
play.modules.enabled += "uk.gov.hmrc.play.bootstrap.HttpClientModule"

import uk.gov.hmrc.play.bootstrap.http.HttpClient
import javax.inject.Inject

class SomeConnector @Inject() (client: HttpClient) {
  
  client.GET[Option[MyCaseClass]]("http://localhost/my-api")
}

User Authorisation

The library supports user authorisation on microservices

Make sure you have the following modules in your application.conf file:

play.modules.enabled += "uk.gov.hmrc.play.bootstrap.AuditModule"
play.modules.enabled += "uk.gov.hmrc.play.bootstrap.HttpClientModule"
play.modules.enabled += "uk.gov.hmrc.play.bootstrap.AuthModule"

Your controller will look like this:

class MyController @Inject() (val authConnector: AuthConnector) extends BaseController with AuthorisedFunctions {
   
   def getSomething(): Action[AnyContent] = Action.async { implicit request ⇒
       authorised() {
         // your protected logic
       } 
   }
 }

MDC Logging

By default the logging MDC will be passed between threads by a custom ExecutorService. While this works in both test and production configurations it does not work in Dev mode using the AkkaHttpServer in Play 2.6.

If you would like the same functionality in Dev mode, you must use the older NettyHttpServer.

• Enable the PlayNettyServer plugin in your build.sbt

  .enablePlugins(PlayNettyServer)

• Set the NettyServerProvider in the devSettings of your build.sbt

  PlayKeys.devSettings += "play.server.provider" -> "play.core.server.NettyServerProvider"

• Make sure you still use the AkkaHttpServer in Prod mode by specifying it in application.conf

play.server.provider = play.core.server.AkkaHttpServerProvider

Migrations

Version 0.37.0

Play auditing

play-auditing was bump in major version - changes in HttpAuditing#auditFromPlayFrontend signature were made. Now method require implicit execution context in scope.

Implicit execution context should be available in most usage places, but this change break API and may require developer attention.
