Features

7.4.0 (2021-10-06)

Features

7.3.1 (2021-10-01)

Bug Fixes

  • Schedulers: Throwing a falsy error in a scheduled function no longer results in strange error objects. (#6594) (c70fcc0)
  • scheduling with Rx-provided schedulers will no longer leak action references (#6562) (ff5a748), closes #6561
  • forkJoin: now finalizes sources before emitting (#6546) (c52ff2e), closes #4914

  • tap: Now supports subscribe, unsubscribe, and finalize handlers (#6527) (eb26cbc)

7.2.0 (2021-07-05)

Bug Fixes

  • debounceTime: unschedule dangling task on unsubscribe before complete (#6464) (7ab0a4c)
  • fromEvent: Types now properly infer when resultSelector is provided (#6447) (39b9d81)

Features

  • Operators are all exported at the top level, from "rxjs". From here on out, we encourage top-level imports with RxJS. Importing from rxjs/operators will be deprecated soon. (#6488) (512adc2), closes #6242

7.1.0 (2021-05-21)

Bug Fixes

  • returned operator functions from multicast operators share, publish, publishReplay are now referentially transparent. Meaning if you take the result of calling publishReplay(3) and pass it to more than one observable's pipe method, it will behave the same in each case, rather than having a cumulative effect, which was a regression introduced sometime in version 6. If you required this broken behavior, there is a workaround posted here (#6410) (e2f2e51), closes /github.com/ReactiveX/rxjs/pull/6410#issuecomment-846087374 #5411

Features

  • All subjects now have an observed property. This will allow users to check whether a subject has current subscribers without us allowing access to the observers array, which is going to be made private in future versions. (#6405) (f47425d)
  • groupBy: Support named arguments, support ObservableInputs for duration selector (#5679) (7a99397)
  • share: use another observable to control resets (#6169) (12c3716)

7.0.1 (2021-05-12)

Bug Fixes

  • bindCallback: resulting function now recreated underlying Subject and is reusable once again. (#6369) (abf2bc1)
  • retry: properly handles retry counts smaller than 1. (#6359) (e797bd7)
  • share: properly closes synchronous "firehose" sources. (#6370) (2271a91)
  • Observable teardowns now properly called if useDeprecatedSynchronousErrorHandling is true. (#6365) (e19e104), closes #6364
  • Subscription: properly release parent subscriptions when unsubscribed. (#6352) (88331d2), closes #6351 #6351
  • node: do not reference DOM-related imports to assist in node usage. (#6305) (b24818e), closes #6297

7.0.0 (2021-04-29)

Bug Fixes

  • VS code will now properly auto-import operators, et al (#6276) (f43c728), closes #6067
  • AjaxResponse: add stricter type (AjaxResponseType) (#6279) (839e192)

7.0.0-rc.3 (2021-04-28)

Bug Fixes

  • finalize behaves well with useDeprecatedSynchronousErrorHandling (#6251) (e4bed2a), closes #6250
  • resolve run-time errors when using deprecated sync error handling (#6272) (35daaf7), closes #6271
  • resolve issue that made users unable to assert instanceof AjaxError. (#6275) (a7c2d29)

Features

BREAKING CHANGES

  • Our very new creation function, connectable, now takes a configuration object instead of just the Subject instance. This was necessary to make sure it covered all use cases for what we were trying to replace in the deprecated multicasting operators. Apologies for the late-in-the-game change, but we know it's not widely used yet (it's new in v7), and we want to get it right.

7.0.0-rc.2 (2021-04-20)

Bug Fixes

  • webSocket: return the correct type for WebSocketSubject multiplex method(#6232) (33383b8)

Reverts

  • remove misused type parameter from static pipe (#6119) (8dc7d17), closes #5557
  • Subscriber: don't leak destination (#6116) (5bba36c)
  • combineLatest: POJO signature should match only ObservableInput values (#6103) (d633494)
  • forkJoin: POJO signature should match only ObservableInput values (#6095) (566427e)
  • predicates that return any will now behave property with findIndex (#6097) (c6f73d6)
  • remove misused type parameter from isObservable (#6083) (f16b634)
  • unhandled errors in observers correctly scheduled (#6118) (c02ceb7)
  • defaultIfEmpty: Allow undefined as an argument, require an argument (4983760), closes #6064
  • elementAt: Allow defaultValue of undefined. (5bc1b3e)
  • first: Allow defaultValue of undefined. (62a6bbe)
  • last: Allow defaultValue of undefined. (ef3e721)

Features

  • rename and alias combineLatest as combineLatestAll for consistency (#6079) (42cee80), closes #4590

BREAKING CHANGES

  • defaultIfEmpty: defaultIfEmpty requires a value be passed. Will no longer convert undefined to null for no good reason.

7.0.0-beta.12 (2021-02-27)

5bc8e3361 Fix/6052 ajax responseType should default to "json" (#6056)

Bug Fixes

  • ajax: responseType is now properly defaulted to "json" again. (#6056) (5bc8e3361)
  • Corner case resolved where an error thrown in a completion handler might delay teardown if it happened to be after a completing operator like take. (#6062) (a2b9563)
  • AsyncGenerator support: consumed async generators are now properly finalized. (#6062) (a2b9563), closes #5998
  • throttle: no longer emits more than necessary in sync/sync trailing case (#6059) (9da638a), closes #6058

7.0.0-beta.11 (2021-02-24)

Bug Fixes

  • ajax: now errors on forced abort (#6041) (d950921), closes #4251
  • buffer: closingNotifier completion does not complete resulting observable (358ae84)
  • buffer: Remaining buffer will correctly be emitted on source close. (0c667d5), closes #3990 #6035
  • debounceTime: improves performance on quick succession of emits (#6049) (9b70861)
  • distinctUntilChanged: Ensure reentrant code is compared properly (#6014) (0ebcf17)
  • share: Ensure proper memory clean up (1aa400a)
  • window: final window stays open until source complete (e8b05ef)
  • concat/merge: operators will finalize inners before moving to the next (#6010) (5249a23), closes #3338
  • predicates that return any will now behave property in TS (#5987) (f5ae97d), closes #5986
  • publish variants returning ConnectableObservable not properly utilizing lift (#6003) (9acb950)
  • Resolve issues with deprecated synchronous error handling and chained operators (#5980) (0ad2802), closes #5979
  • useDeprecatedSynchronousErrorThrowing honored for flattened sync sources (#5984) (abd95ce), closes #5983

Features

BREAKING CHANGES

  • window: The windowBoundaries observable no longer completes the result. It was only ever meant to notify of the window boundary. To get the same behavior as the old behavior, you would need to add an endWith and a skipLast(1) like so: source$.pipe(window(notifier$.pipe(endWith(true))), skipLast(1)).
  • buffer: Final buffered values will now always be emitted. To get the same behavior as the previous release, you can use endWith and skipLast(1), like so: source$.pipe(buffer(notifier$.pipe(endWith(true))), skipLast(1))
  • buffer: closingNotifier completion no longer completes the result of buffer. If that is truly a desired behavior, then you should use takeUntil. Something like: source$.pipe(buffer(notifier$), takeUntil(notifier$.pipe(ignoreElements(), endWith(true)))), where notifier$ is multicast, although there are many ways to compose this behavior.

7.0.0-beta.10 (2021-01-18)

Bug Fixes

  • combineLatest: Ensure EMPTY is returned if no observables are passed. (#5963) (157c7e8), closes #5962
  • fromEvent: fixed HasEventTargetAddRemove to support EventTarget types (#5945) (5f022d7)

Features

  • connect: Adds new connect operator. (9d53af0)
  • connectable: Adds connectable creation method (f968a79)
  • share: Make share completely configurable. Also adds SubjectLike. (2d600c7)
  • TestScheduler: add expectObservable(a$).toEqual(b$). (3372c72)

Performance Improvements

  • ensure same hidden class for OperatorSubscriber (#5878) (246b449)

BREAKING CHANGES

  • share: The TypeScript type Subscribable now only supports what is a valid return for [Symbol.observable]().
  • share: The TypeScript type Observer no longer incorrectly has an optional closed property.

7.0.0-beta.9 (2020-12-07)

Bug Fixes

  • audit: don't signal on complete (54cb428)
  • bufferToggle: don't signal on complete (65686ff)
  • bufferWhen: don't signal on complete (a2ba364)
  • debounce: don't signal on complete (c919c68)
  • delayWhen: no longer emits if duration selector is empty (#5769) (0872341), closes #3665
  • forkJoin: ensure readonly array argument forkJoin([a$, b$, c$] as const) result is correct (6baec53)
  • iif: No longer allow accidental undefined arguments (#5829) (23b98b4)
  • sample: don't signal on complete (95e0b70)
  • Symbol.observable: properly defined as a unique symbol. (#5874) (374138e), closes #5861 #4415
  • throttle: don't signal on complete (4af0227)
  • windowToggle: don't signal on complete (9cb56c4), closes #5838
  • use empty object type in combineLatest/forkJoin sigs (#5832) (22aaaa2)
  • withLatestFrom: allow synchronous source (#5828) (adbe65e)

Features

BREAKING CHANGES

  • windowToggle: the observable returned by the windowToggle operator's closing selector must emit a next notification to close the window. Complete notifications no longer close the window.
  • bufferToggle: the observable returned by the bufferToggle operator's closing selector must emit a next notification to close the buffer. Complete notifications no longer close the buffer.
  • bufferWhen: the observable returned by the bufferWhen operator's closing selector must emit a next notification to close the buffer. Complete notifications no longer close the buffer.
  • debounce: the observable returned by the debounce operator's duration selector must emit a next notification to end the duration. Complete notifications no longer end the duration.
  • throttle: the observable returned by the throttle operator's duration selector must emit a next notification to end the duration. Complete notifications no longer end the duration.
  • sample: the sample operator's notifier observable must emit a next notification to effect a sample. Complete notifications no longer effect a sample.
  • audit: the observable returned by the audit operator's duration selector must emit a next notification to end the duration. Complete notifications no longer end the duration.
  • Symbol.observable: rxjs@7 is only compatible with @types/node@14.14.3 or higher and symbol-observable@3.0.0 and higher. Older versions of @types/node incorrectly defined Symbol.observable and will be in conflict with rxjs and symbol-observable@3.0.0.
  • delayWhen: delayWhen will no longer emit if the duration selector simply completes without a value. Notifiers must notify with a value, not a completion.
  • iif: iif will no longer allow result arguments that are undefined. This was a bad call pattern that was likely an error in most cases. If for some reason you are relying on this behavior, simply substitute EMPTY in place of the undefined argument. This ensures that the behavior was intentional and desired, rather than the result of an accidental undefined argument.

7.0.0-beta.8 (2020-10-15)

Bug Fixes

  • audit, auditTime: audit and auditTime emit last value after source completes (#5799) (643bc85), closes #5730
  • No longer allow invalid "Subscribable" type as valid observable source in from and others. (258dddd), closes #4532
  • bindNodeCallback: ensure underlying function is not called twice during subscription (#5780) (74aa4b2)
  • delay: Now properly handles Date and negative numbers (#5719) (868c02b), closes #5232
  • delayWhen: only deprecates when subscriptionDelay presents (#5797) (43d1731)
  • every: index properly increments in predicate (5686f83)
  • firstValueFrom: now unsubscribes from source after first value is received (#5813) (a321516), closes #5811
  • from: objects that are thennable that happen to have a subscribe method will no longer error. (789d6e3)
  • fromEvent: now properly types JQuery event targets (b5aa15a)
  • mergeScan: no longer emits state again upon completion. (#5805) (68c2894), closes #5372
  • throttle: now supports synchronous duration selectors (55e953e), closes #5658
  • throttle: trailing values will now emit after source completes (d5fd69c)
  • timeout: allows synchronous observable as a source (84c5c0b), closes #5746
  • zip: zip now accepts an array of arguments like its counterparts (3123b67)

Code Refactoring

  • count: Base off of reduce. (98a6d09)
  • pairs: Based off of from and Object.entries (#5775) (d39f830)

Features

BREAKING CHANGES

  • mergeScan: mergeScan will no longer emit its inner state again upon completion.
  • pairs: pairs will no longer function in IE without a polyfill for Object.entries. pairs itself is also deprecated in favor of users just using from(Object.entries(obj)).
  • zip: Zipping a single array will now have a different result. This is an extreme corner-case, because it is very unlikely that anyone would want to zip an array with nothing at all. The workaround would be to wrap the array in another array zip([[1,2,3]]). But again, that's pretty weird.
  • count: No longer passes source observable as a third argument to the predicate. That feature was rarely used, and of limited value. The workaround is to simply close over the source inside of the function if you need to access it in there.

7.0.0-beta.7 (2020-09-23)

Bug Fixes

  • multicast: and other publish variants will handle errors thrown in a selector appropriately (bde8eda)

Code Refactoring

  • tap: reduce the size of the implementation (1222d5a)
  • Subscriber: Massively untangle Subscriber and SafeSubscriber (07902ca)

BREAKING CHANGES

  • Subscriber: new Subscriber no longer takes 0-3 arguments. To create a Subscriber with 0-3 arguments, use Subscriber.create. However, please note that there is little to no reason that you should be creating Subscriber references directly, and Subscriber.create and new Subscriber are both deprecated.

7.0.0-beta.6 (2020-09-23)

Bug Fixes

Code Refactoring

  • Massive Size Reduction: reduced the size of all operator implementations as well as other utilities and types (#5729) (4d3fc23)

Features

  • onUnhandledError: configuration point added for unhandled errors (#5681) (3485dd5)
  • skipLast: counts zero or less will mirror the source (02e113b)

BREAKING CHANGES

  • skipLast: skipLast will no longer error when passed a negative number, rather it will simply return the source, as though 0 was passed.
  • map: thisArg will now default to undefined. The previous default of MapSubscriber never made any sense. This will only affect code that calls map with a function and references this like so: source.pipe(map(function () { console.log(this); })). There wasn't anything useful about doing this, so the breakage is expected to be very minimal. If anything we're no longer leaking an implementation detail.
  • onUnhandledError: Errors that occur during setup of an observable subscription after the subscription has emitted an error or completed will now throw in their own call stack. Before it would call console.warn. This is potentially breaking in edge cases for node applications, which may be configured to terminate for unhandled exceptions. In the unlikely event this affects you, you can configure the behavior to console.warn in the new configuration setting like so: import { config } from 'rxjs'; config.onUnhandledError = (err) => console.warn(err);

  • zip: zip operators and functions are now able to zip all iterable sources (#5688) (02c3a1b), closes #4304
  • switchMap and exhaustMap behave correctly with re-entrant code. (c289688)
  • webSocket: close websocket connection attempt on unsubscribe (e1a671c), closes #4446

Code Refactoring

  • Subscription: remove will now remove any teardown by reference (#5659) (1531152)
  • throwError: now accepts a factory to create the error (#5647) (dad270a), closes #5617
  • useDeprecatedNextContext: Puts deprecated next context behavior behind a flag (dfdef5d)
  • support schedulers within run (#5619) (c63de0d)

Performance Improvements

  • SafeSubscriber: avoid using Object.create (40a9e77)

BREAKING CHANGES

  • ajax:
    • ajax body serialization will now use default XHR behavior in all cases. If the body is a Blob, ArrayBuffer, any array buffer view (like a byte sequence, e.g. Uint8Array, etc), FormData, URLSearchParams, string, or ReadableStream, default handling is use. If the body is otherwise typeof "object", then it will be converted to JSON via JSON.stringify, and the Content-Type header will be set to application/json;charset=utf-8. All other types will emit an error.
    • The Content-Type header passed to ajax configuration no longer has any effect on the serialization behavior of the AJAX request.
    • For TypeScript users, AjaxRequest is no longer the type that should be explicitly used to create an ajax. It is now AjaxConfig, although the two types are compatible, only AjaxConfig has progressSubscriber and createXHR.

  • zip: zip operators will no longer iterate provided iterables "as needed", instead the iterables will be treated as push-streams just like they would be everywhere else in RxJS. This means that passing an endless iterable will result in the thread locking up, as it will endlessly try to read from that iterable. This puts us in-line with all other Rx implementations. To work around this, it is probably best to use map or some combination of map and zip. For example, zip(source$, iterator) could be source$.pipe(map(value => [value, iterator.next().value])).

  • Subscription: add no longer returns an unnecessary Subscription reference. This was done to prevent confusion caused by a legacy behavior. You can now add and remove functions and Subscriptions as teardowns to and from a Subscription using add and remove directly. Before this, remove only accepted subscriptions.

  • RxJS Error types Tests that are written with naive expectations against errors may fail now that errors have a proper stack property. In some testing frameworks, a deep equality check on two error instances will check the values in stack, which could be different.

  • Undocumented Behaviors/APIs Removed:

    • unsubscribe no longer available via the this context of observer functions. To reenable, set config.useDeprecatedNextContext = true on the rxjs config found at import { config } from 'rxjs';. Note that enabling this will result in a performance penalty for all consumer subscriptions.
    • Leaked implementation detail _unsubscribeAndRecycle of Subscriber has been removed. Just use new Subscription objects
    • Removed an undocumented behavior where passing a negative count argument to retry would result in an observable that repeats forever.
    • An undocumented behavior where passing a negative count argument to repeat would result in an observable that repeats forever.
    • The static sortActions method on VirtualTimeScheduler is no longer publicly exposed by our TS types.

  • throwError: In an extreme corner case for usage, throwError is no longer able to emit a function as an error directly. If you need to push a function as an error, you will have to use the factory function to return the function like so: throwError(() => functionToEmit), in other words throwError(() => () => console.log('called later')).

7.0.0-beta.4 (2020-08-02)

Bug Fixes

  • ajax: Partial observers passed to progressSubscriber will no longer error (25d279f)
  • ajax: Unparsable responses will no longer prevent full AjaxError from being thrown (605ee55)
  • animationFrames: emit the timestamp from the rAF's callback (#5438) (c980ae6)
  • Ensure unsubscriptions/teardowns on internal subscribers are idempotent (#5465) (3e39749), closes #5464
  • timeout: defer error creation until timeout occurs (#5497) (3be9840), closes #5491

Code Refactoring

  • ajax: Drop support for IE10 and lower (0eaadd6)
  • Observable: Update property and method types (#5572) (144b626)

Features

  • combineLatest: support for observable dictionaries (#5022) (#5363) (f5278aa)
  • TestScheduler: add an animate "run mode" helper (#5607) (edd6731)
  • timeout: One timeout to rule them all (def1d34)

BREAKING CHANGES

  • ajax: In an extreme corner-case... If an error occurs, the responseType is "json", we're in IE, and the responseType is not valid JSON, the ajax observable will no longer emit a syntax error, rather it will emit a full AjaxError with more details.
  • ajax: Ajax implementation drops support for IE10 and lower. This puts us in-line with other implementations and helps clean up code in this area
  • Observable: lift no longer exposed. It was NEVER documented that end users of the library should be creating operators using lift. Lift has a variety of issues and was always an internal implementation detail of rxjs that might have been used by a few power users in the early days when it had the most value. The value of lift, originally, was that subclassed Observables would compose through all operators that implemented lift. The reality is that feature is not widely known, used, or supported, and it was never documented as it was very experimental when it was first added. Until the end of v7, lift will remain on Observable. Standard JavaScript users will notice no difference. However, TypeScript users might see complaints about lift not being a member of observable. To workaround this issue there are two things you can do: 1. Rewrite your operators as outlined in the documentation, such that they return new Observable. or 2. cast your observable as any and access lift that way. Method 1 is recommended if you do not want things to break when we move to version 8.

  • shareReplay: no longer misses synchronous values from source (92452cc)
  • interop: chain interop/safe subscriber unsubscriptions correctly (#5472) (98ad0eb), closes #5469 #5311 #2675
  • finalize: chain subscriptions for interop with finalize (#5239) (04ba662), closes #5237 #5237
  • animationFrameScheduler: don't execute rescheduled animation frame and asap actions in flush (#5399) (33c9c8c), closes #4972 #5397
  • iterables: errors thrown from iterables now properly propagated (#5444) (75d4c2f)

  • subscribeOn: allow Infinity as valid delay (#5500) (cd7d649)
  • Subject: resolve issue where Subject constructor errantly allowed an argument (#5476) (e1d35dc)
  • Subject: no default generic (e678e81)
  • defer: No longer allows () => undefined to observableFactory (#5449) (1ae937a), closes #5449

  • raceWith: add raceWith, the renamed race operator (#5303) (ca7f370)
  • fetch: add selector (#5306) (99b5af1), closes #4744
  • TimestampProvider: Reduced scheduler footprint for default usage of shareReplay, timeInterval, and timestamp (#4973) (b2e67e3)

BREAKING CHANGES

  • Notification.createNext(undefined) will no longer return the exact same reference every time.

  • Type signatures tightened up around Notification and dematerialize, may uncover issues with invalid types passed to those operators.

  • Experimental support for for await as been removed. Use https://github.com/benlesh/rxjs-for-await instead.

  • defer no longer allows factories to return void or undefined. All factories passed to defer must return a proper ObservableInput, such as Observable, Promise, et al. To get the same behavior as you may have relied on previously, return EMPTY or return of() from the factory.

  • single operator will now throw for scenarios where values coming in are either not present, or do not match the provided predicate. Error types have thrown have also been updated, please check documentation for changes.

  • take and will now throw runtime error for arguments that are negative or NaN, this includes non-TS calls like take().

  • takeLast now has runtime assertions that throw TypeErrors for invalid arguments. Calling takeLast without arguments or with an argument that is NaN will throw a TypeError

  • ReplaySubject no longer schedules emissions when a scheduler is provided. If you need that behavior, please compose in observeOn using pipe, for example: new ReplaySubject(2, 3000).pipe(observeOn(asap))

  • timestamp operator accepts a TimestampProvider, which is any object with a now method that returns a number. This means pulling in less code for the use of the timestamp operator. This may cause issues with TestScheduler run mode. (Issue here: https://github.com/ReactiveX/rxjs/issues/5553)

  • of: Generic signature changed, do not specify generics, allow them to be inferred or use as
  • of: Use with more than 9 arguments, where the last argument is a SchedulerLike may result in the wrong type which includes the SchedulerLike, even though the run time implementation does not support that. Developers should be using scheduled instead
  • TS: RxJS requires TS 3.5
  • rxjs-compat: rxjs/Rx is no longer a valid import site.
  • rxjs-compat: rxjs-compat is not published for v7 (yet)

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 idea 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.

  • 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).
