Add an afterInitProcessor handler that will be called after Sentry is initialized

[alSergey]

Problem Statement

There is currently no way to subscribe to Sentry's initialization event and execute arbitrary code. This may be necessary if the project uses some custom subscriptions that depend on Sentry and they must be executed after Sentry is initialized.

Solution Brainstorm

Add a new hook that will receive a callback that will be called after Sentry is initialized. It should work similarly to addEventProcessor (it accepts a callback and calls it after initialization).

Hey @alSergey thanks for writing in!

I'm curious about your use case:

Can you elaborate on that? This is the first time we're hearing about this and I'm curious :)

Generally, initializing the SDK via Sentry.init is synchronous, so I'd argue you can emit an event yourself simply after the init call if that makes sense:

Sentry.init({});
notifyListenersThatSentryIsInitialized(); // #namingishard

Let me know if this works for you

@Lms24 Thank you very much for the advice, I hadn't thought of that. Everything worked.
