  💥 BREAKING CHANGES

  • ajax: will no longer execute a CORS request by default, you must opt-in with the crossDomain flag in the config.
  • 🔀 mergeMap|concatMap|concatMapTo: mergeMap, concatMap and concatMapTo no longer support a result selector, if you need to use a result selector, use the following pattern: source.mergeMap(x => of(x + x).pipe(map(y => y + x)) (the pattern would be the same for concatMap).
  • never: no longer exported. Use the NEVER constant instead.
  • bindCallback: removes result selector, use map instead: bindCallback(fn1, fn2)() becomes bindCallback(fn1)().pipe(map(fn2))
  • Rx.ts: importing from rxjs/Rx is no longer available. Upcoming backwards compat solution will allow that
  • Symbol.iterator: We are no longer polyfilling Symbol.iterator. That would be done by a proper polyfilling library
  • Observable.if: TypeScript users using Observable.if will have to cast Observable as any to get to if. It is a better idae to just use iif directly via import { iif } from 'rxjs';
  • bindNodeCallback: resultSelector removed, use map instead: bindNodeCallback(fn1, fn2)() becomes bindNodeCallback(fn1)().pipe(map(fn2))
  • Symbol.observable: RxJS will no longer be polyfilling Symbol.observable. That should be done by an actual polyfill library. This is to prevent duplication of code, and also to prevent having modules with side-effects in rxjs.
  • fromEvent: result selector removed, use map instead: fromEvent(target, 'click', fn) becomes fromEvent(target, 'click').pipe(map(fn))
  • last: no longer accepts resultSelector argument. To get this same functionality, use map.
  • first: no longer supports resultSelector argument. The same functionality can be achieved by simply mapping either before or after first depending on your use case.
  • exhaustMap: resultSelector no longer supported, to get this functionality use: source.pipe(exhaustMap(x => of(x + x).pipe(map(y => x + y))))
  • switchMap|switchMapTo: switchMap and switchMapTo no longer take resultSelector arguments, to get the same functionality use switchMap and map in combination: source.pipe(switchMap(x => of(x + x).pipe(y => x + y))).
  • 🔀 mergeMapTo: mergeMapTo no longer accepts a resultSelector, to get this functionality, you'll want to use mergeMap and map together: source.pipe(mergeMap(() => inner).pipe(map(y => x + y)))
  • fromEventPattern: no longer supports a result selector, use map instead: fromEventPattern(fn1, fn2, fn3) becomes fromEventPattern(fn1, fn2).pipe(map(fn3))

  💥 BREAKING CHANGES

  • webSocket: webSocket creator function now exported from rxjs/websocket as websocket.
  • IteratorObservable: IteratorObservable no longer share iterator between subscription
  • utils: Many internal use utilities like isArray are now hidden under rxjs/internal, they are implementation details and should not be used.
  • ✅ testing observables: HotObservable and ColdObservable, and other testing support types are no longer exported directly.
  • creation functions: All create functions such as of, from, combineLatest and fromEvent should now be imported from rxjs/create.
  • types and interfaces: Can no longer explicitly import types from rxjs/interfaces, import them from rxjs instead
  • symbols: Symbols are no longer exported directly from modules such as rxjs/symbol/observable please use Symbol.observable and Symbol.iterator (polyfills may be required)
  • deep imports: Can no longer deep import top-level types such as rxjs/Observable, rxjs/Subject, rxjs/ReplaySubject, et al. All imports should be done directly from rxjs, for example: import \{ Observable, Subject \} from 'rxjs';
  • ⏱ schedulers: Scheduler instances have changed names to be suffixed with Scheduler, (e.g. asap -> asapScheduler)
  • operators: Pipeable operators must now be imported from rxjs like so: import { map, filter, switchMap } from 'rxjs/operators';. No deep imports.
  • ajax: Ajax observable should be imported from rxjs/ajax.
  • Observable: You should no longer deep import custom Observable implementations such as ArrayObservable or ForkJoinObservable.
  • _throw: _throw is now exported as throwError
  • if: if is now exported as iif
  • operators: Deep imports to rxjs/operator/* will no longer work. Again, pipe operators are still where they were.
  • error handling: Unhandled errors are no longer caught and rethrown, rather they are caught and scheduled to be thrown, which causes them to be reported to window.onerror or process.on('error'), depending on the environment. Consequently, teardown after a synchronous, unhandled, error will no longer occur, as the teardown would not exist, and producer interference cannot occur
  • distinct: Using distinct requires a Set implementation and must be polyfilled in older runtimes
  • asap: Old runtimes must polyfill Promise in order to use ASAP scheduling.
  • groupBy: Older runtimes will require Map to be polyfilled to use groupBy
  • TypeScript: IE10 and lower will need to polyfill Object.setPrototypeOf
  • 🚚 operators removed: Operator versions of static observable creators such as merge, concat, zip, onErrorResumeNext, and race have been removed. Please use the static versions of those operations. e.g. a.pipe(concat(b, c)) becomes concat(a, b, c).

• v5.5.6 Changes
