"unhandledRejection" for Observables

[Alexander Mills]

In front-end JS, is there a way to catch errors globally?

For example, we might have:

const o = new Observable(o => {

    o.error('unhandled error')

});

o.subscribe(v => console.log('this never happens')

so we have a 1 sub, and so the observable becomes active, but there is nobody to catch the error, is there a way to capture the error globally?

Hi Alexander,

You could use an error callback in the subscription:

o.subscribe(

v => console.log('this never happens'),

err => console.log('this happens ;-)', err)

);
