No way to tell when `Sentry.init()` is complete

Reading the docs, and some of the code, I cant see a way to tell when Sentry.init() is complete.

This is making it difficult to capture application errors that occur before Sentry is setup. From what I understand, Sentry will:

only monitor global errors and unhandled promise for you until the SDK is fully loaded

But, what if I want to wait until Sentry is loaded before I bootstrap my application? That way I can be confident that the errors are captured.

Right now, I’m loading Sentry after my app is ready. But app errors are ignored as Sentry isnt ready until after init.

// ... my app init is before this
Sentry.init({
    dsn: sentryDsn,
    environment: environment,
    debug: environment === 'local'
});
// these undefined errors are never captured
var a = b + c;

What I am wondering is how I can make sure Sentry “is done and ready” so that I can boot up my app and make sure app-level errors are captured?

@egor-sorokin can you take a look at our old plugin code and try to “port” it to your project? https://github.com/getsentry/sentry-javascript/blob/master/packages/raven-js/plugins/angular.js#L12-L49

It should be rather straightforward. We don’t document Angular 1.x anymore, as there are not many reports of people using it. We may need to do it though, if there are issues like the one mentioned above.

I recently faced the same problem: @sentry/browser: v 4.1.1 I have an angularjs app and I initialised Sentry before the main app (and I tried to initialise it in angular.run()), like so:

import * as Sentry from '@sentry/browser';

Sentry.init({
    dsn: myDsn,
    beforeBreadcrumb: function(breadcrumb, hint) {
        return null;
    },
    beforeSend: function(event) {
        console.log(event);
        return event;
    }
})

Then I put errors in controllers & factories but none of them was caught. After that I added a timeout with 0ms and it started work. Code snippet from angularjs controller:

var d = new Date();
setTimeout(function() {
      // sentry tracks the error below
      throw new Error('timeout' + d.getHours() + ':' + d.getMinutes() + ':' + d.getSeconds());
}, 0);

// sentry doesn't track the error below
throw new Error('no timeout' + d.getHours() + ':' + d.getMinutes() + ':' + d.getSeconds());

@james2doyle example doesn’t work for me at all
