lagom-java-sbt-chirper-example

A Lagom Java example showcasing a Twitter-like application, sbt flavor.

Running locally

1. Start all services using sbt runAll.
2. Open http://localhost:9000 in your browser.
3. Register and Start Chirping!

lagom-java-sbt-chirper-example's Issues

Why does the example require an internet connection?

When I'm connected to an internet connection, the example works. When I'm not connected to an internet connection, or I'm behind a firewall, then the example does not work.

Does anyone know what part of the code is trying to connect to the internet so that I can cut it out?

Thank you!

My best,
Michael

update helm intructions in KUBERNETES.md file

I hit some error after updating my minikube cluster. I wasn't able to install the helm charts anymore.

This issues fnproject/fn-helm#21 gives more details on this.

https://github.com/lightbend/helm-charts seems to contain the right instructions, but this was not reflected in the Chirper instructions.

Remove use of RP tools (and docs)

This repo still demoes addSbtPlugin("com.lightbend.rp" % "sbt-reactive-app" % "1.5.0") and documents its usage.

Bump Lagom version to 1.4.8

Lagom 1.4.8 will soon be available. This will use 2.5.16 which fixes a vulnerability. See lagom/lagom#1562 so this sample should move up to 1.4.8. Thanks.

Use webpack-dev-server

I initially integrated sbt-webpack. However, I've found that I much prefer letting webpack-dev-server handle the JS compilation when in development mode. There's a good example of how to do it in arpossatto/play-webpack-dev-react-boilerplate. It'd be nice to remove sbt-webpack and use this method instead

[error] aka.actor.ActorSystemImpl, sending 500 response

Hi,

I went through the instructions for running locally in the readme. However, when I go to localhost:9000, nothing appears to load on the screen, and I get the following error on the command line:

2018-06-11T14:12:55.095Z [error] akka.actor.ActorSystemImpl [sourceThread=application-akka.actor.default-dispatcher-13, akkaSource=akka.actor.ActorSystemImpl(application), sourceActorSystem=application, akkaTimestamp=14:12:55.091UTC] - Internal server error, sending 500 response

akka.stream.StreamTcpException: Tcp command [Connect(0.0.0.0:57143,None,List(),Some(10 seconds),true)] failed because of Connect timeout of Some(10 seconds) expired

One thing I noticed, however, is that if I go to localhost:57143 (where the front end is listening), the chirper UI loads up. However, I am not able to sign up or actually do anything.

Any suggestions? Thank you!

My best,
Michael

P.S - I'm running on a macOS Sierra.

Current issue

After fresh clone of repo, running sbt runAll starts, attempting to access http://localhost:9000 on my browser throws the following error (note this is from my console which is the same):

Other then installing nvm via brew, and rather then the setup script everything else was the same.

No changes were made to the repo prior to running sbt runAll.

Expected Behaviour

Should load up a page

Attempted fixes

• Have reviewed the sbt build files and tried playing with Webjar-play version.
• Tried redownloading the repo
• Extensively googled possible solutions finding mainly a mention of assetmanager

Review repo settings

• branch protections
• default branch
• CLA validator and write-bot settings
