useSubject
Bind Subject to ref and propagate value changes both ways.
Demo
available in add-on @vueuse/rxjsUsage
import { useSubject } from '@vueuse/rxjs'
import { Subject } from 'rxjs'
const subject = new Subject()
// setup()
const subjectRef = useSubject(subject)
import { useSubject } from '@vueuse/rxjs'
import { Subject } from 'rxjs'
const subject = new Subject()
// setup()
const subjectRef = useSubject(subject)
If you want to add custom error handling to a Subject that might error, you can supply an optional onError configuration. Without this, RxJS will treat any error in the supplied observable as an "unhandled error" and it will be thrown in a new call stack and reported to window.onerror (or process.on('error') if you happen to be in node).
import { useSubject } from '@vueuse/rxjs'
import { Subject } from 'rxjs'
const subject = new Subject()
// setup()
const subjectRef = useSubject(subject,
{
onError: (err) => {
console.log(err.message) // "oops"
},
},
)
import { useSubject } from '@vueuse/rxjs'
import { Subject } from 'rxjs'
const subject = new Subject()
// setup()
const subjectRef = useSubject(subject,
{
onError: (err) => {
console.log(err.message) // "oops"
},
},
)
