Features

• Functional Reactive Programming Frameworks - Models asynchronous data flows and events as declarative streams using functional reactive programming patterns.
• Reactive Programming Libraries - Provides a framework for composing asynchronous and event-based programs using functional reactive programming in JavaScript and TypeScript.
• Event-to-Stream Conversions - Provides a comprehensive set of utilities to generate event streams from DOM events, promises, callbacks, and polling functions.
• Asynchronous Flow Coordination - Provides declarative operators for managing the synchronization and resolution of concurrent asynchronous event streams.
• Functional Programming Libraries - Implements a comprehensive set of functional programming primitives like map, filter, fold, and zip for stream processing.
• Stream-to-Property Conversions - Provides a utility to transform a discrete event stream into a property that remembers and provides its current value.
• Functional State Management - Evolves properties from initial values using pure functions and transition logic based on input patterns.
• Atomic State Primitives - Provides atomic state primitives that prevent inconsistent transitional states when properties depend on multiple shared sources.
• Event Debouncing - Delays the emission of an event until a specified quiet period has passed.
• Event Debouncing - Limits the rate of events using a combination of debouncing and duplicate suppression.
• Event Stream Merging - Manages multiple event sources using patterns like zipping and merging to synchronize timing and data.
• Event Subscriptions - Provides a mechanism to execute a callback function for every new value, error, or end event produced by a stream.
• Event-to-State Transformations - Transforms a stream of asynchronous input events into a continuous representation of application state.
• Functional Pipelines - Implements architectural patterns for chaining data transformations using pure functions in a declarative pipeline.
• Observer Patterns - Distributes discrete events from a single source to multiple subscribers through callback registration.
• Push-Based Data Propagation - Propagates values immediately from producers to consumers without requiring a request for data.
• Reactive State Management - Tracks and evolves application state over time by accumulating stream values through reducers and state machines.
• Reactive Stream Filtering - Excludes events from a stream based on a predicate function or the current value of a property.
• Reactive Value Combinations - Provides utilities to merge multiple properties or streams using logical operators or custom functions to produce derived values.
• Reactive Value Mapping - Transforms each value in a stream using a provided function or the current value of another property.
• Stream Element Grouping - Splits a single stream into multiple sub-streams based on a key-generating function.
• Stream Mapping and Flattening - Provides mechanisms to merge nested streams based on incoming events using various concurrency and switching strategies.
• Atomic State Synchronization - Provides atomic state synchronization to prevent transitional glitches in derived properties sharing a common source.
• Stream Event Throttling - Limits the rate of emitted events by discarding excessive events or buffering them to ensure a minimum interval.
• DOM Event Stream Binding - Binds event streams directly to DOM elements or objects that implement listener methods.
• Observable Event Stream Frameworks - Provides a complete framework for creating, transforming, and merging event streams from DOM events, promises, and callbacks.
• Static Array Conversions - Transforms static lists of values or errors into event streams for sequential delivery.
• Promise-to-Stream Conversions - Transforms a promise into a stream that emits the resolved value or error followed by a completion signal.
• Event Buffering - Collects incoming events and releases them in batches based on a defined schedule or manual trigger.
• Conditional - Buffers events in a stream when a controlling property is truthy and releases them when falsy.
• Async Workflow Orchestration - Converts promises and callbacks into streams to handle retries, concurrency limits, and stale request cancellation.
• Timed Event Scheduling - Schedules delayed or recurring tasks using custom time-tracking mechanisms for consistent event timing.
• Event Stream Join Patterns - Coordinates multiple streams using join patterns to emit values only when specific combinations of events occur.
• Async Operation Coordinators - Coordinates asynchronous requests by switching to the latest result and ignoring stale responses.
• Asynchronous Error Handling - Allows subscribing to error events within a stream to perform recovery or logging actions.
• Constant Reactive Properties - Allows the definition of reactive properties that emit a single unchanging value to all subscribers.
• Custom Observable Binders - Enables the creation of streams using binder functions to manage subscription lifecycles and push values to a sink.
• Duplicate Removal - Drops consecutive identical elements from a stream to prevent redundant downstream processing.
• Programmatic Value Injection - Allows users to inject values into a stream programmatically or plug other streams into a central event bus.
• Initial Value Emission - Provides a mechanism to send the current state of a property immediately upon subscription to provide an initial value.
• Event - Controls the frequency of high-volume data emissions using debouncing, throttling, and duplicate suppression.
• Sequential Stream Concatenation - Implements a mechanism to subscribe to multiple event sources sequentially, ensuring each finishes before the next starts.
• Side Effect Discarding - Allows executing functions for side effects on every stream value while preserving the original data flow.
• Application State Machines - Implements state machine processing to manage internal state and emit outputs based on incoming stream events.
• Stream Element Limiting - Implements utilities to drop a specific number of leading elements or ignore events until a trigger occurs.
• Stream Event Interception - Ships a feature to execute side-effect functions for every value or error event before dispatching to subscribers.
• Stream Sampling - Captures the current value of a stream only when a separate sampler stream emits an event.
• Stream State Accumulation - Tracks internal state over time by applying a transition function to every incoming event via stream accumulation.
• Stream-to-Promise Conversions - Resolves a promise using either the first or the last event produced by an observable source.
• Subscription Lifecycle Management - Handles resource cleanup by tracking and disposing of event listeners when streams terminate to prevent memory leaks.
• Time-Based Event Scheduling - Controls event emission rates using internal timers for debouncing, throttling, and delayed delivery.
• Timed Interval Generators - Produces a stream that emits a specific value repeatedly at a defined millisecond interval.
• Stream Combinators - Pairs values from multiple streams one-to-one to emit a combined result using a zip operator.
• DOM & Event Handling - Binds browser DOM events to reactive streams to filter and transform user interactions into structured data.
• Data Polling - Implements a feature to execute a function at a fixed interval to generate stream values until an end signal is received.
• Callback-to-Stream Adapters - Provides adapters that convert single-execution or error-first callbacks into observable reactive streams.
• Functional Programming - Functional reactive programming library.
• Reactive Programming - Functional reactive programming library.
• JavaScript 框架汇总 - Listed in the “JavaScript 框架汇总” section of the Awesome Frontend awesome list.
