bootstrap-play-26

This library is deprecated now. Please use bootstrap-play

Download

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 4.0.0

auth-client

Added Identity Verification (IV) CL250 support via auth-client 5.6, see May 2021 Tech Blog Post on this.

Version 3.0.0

http-verbs

Http-verbs has been bumped to major version 13.0.0. See http-verbs for details.

configuration

auditing.auditExtraHeaders as been renamed to auditing.auditSentHeaders

Invalid config key Should now be
auditing.auditExtraHeaders auditing.auditSentHeaders

Version 2.0.0

http-verbs

Http-verbs has been bumped to major version 12.0.0. See http-verbs for details.

configuration

The following configuration has been renamed, the previous keys are invalid and will need to be updated.

Invalid config key Should now be
httpHeadersWhitelist bootstrap.http.headersAllowlist
csrfexceptions.whitelist bootstrap.csrfexceptions.allowlist

Version 1.15.0

Hmrc time library

As of version 1.15.0, bootstrap-play-26 stops pulling in hmrc/time library transitively anymore. If you require hmrc/time, you will have to add an explicit dependency yourself.
