Hi Kartheek,

There seems to be a bug in the way we publish our Angular module and hence the dependency injection does not work properly.

I am already on it, Please follow it along here for the update https://github.com/elastic/apm-agent-rum-js/issues/437


@vigneshshanmugam thank you for your response. One question I have is do you recommend using this version of angular-rum in production environment or would be recommend us waiting for a stable version?

Hi Kartheek,

We have released a new version of @elastic/apm-rum-angular@0.2.1 which should fix the above issue. The ApmService provider would need explicit injection to make it work with Angular CLI. Please refer to the doc - https://www.elastic.co/guide/en/apm/agent/rum-js/master/angular-integration.html

You can use it in production right now, we did not release a major version 1.x since we might explore API changes in the future if required.

Let us know how it works out for you.


Thank you I will try the new version now.
