computed 0.4.1

Straightforward, reliable, performant and testable reactive state management

0.4.1 - 2023-12-26

• ValueStream: Support initial values

0.4.0 - 2023-12-25

• Added effects: A simpler way to express side effects using multiple data sources/computations
• Async mode for computations starting async operations
• .unwrap to make computed async operations easier to use
• Stream utils: ValueStream and ResourceStream
• Cycle detection: Walk the dag explicitly instead of recomputing the upstream
• Unset _currentComputation before notifying listeners
• Subclass-customizable behaviour for when a computation's dependency has changed
• Trigger the current Zone's handleUncaughtError if a computation which has listeners throws but none of the listeners have an error handler

0.3.2 - 2023-12-21

• Allow computations to use other computations via .asStream
• Added useOr

0.3.1 - 2023-12-17

• Disallow computations from doing most async operations
• Bugfix for non-memoized computations
• Avoid modifying internal state in asserts
• Move _reacting to the global context to save memory

0.3.0 - 2023-12-11

• Removed .useAll, replace with .react.
• Introduced non-memoized computations.
• Removed .withSelf, replaced with .withPrev.
• Introduced prevOr: Returns a given fallback value instead of throwing NoValueException.
• Bugfixes
• Introduced a shorthand dollar notation for defining computed values.
• Allow data source initial values to be specified as functionals.

0.2.2 - 2023-11-28

• Improve dependencies

0.2.1 - 2023-11-27

• Loosen semver bound on test
• Fix README

0.2.0 - 2023-11-26

• .useAll for streams: Disables memoization
• Ability to mock emit events from data sources directly
• Memoize exceptions as well
• Allow computations to re-run even with upstream nodes without values
• asStream: Use a StreamController
• Added asBroadcastStream: Uses a StreamController.broadcast
• Native public listen method
• Assert if the computation returns a value on the first run but throws on the second

0.1.0 - 2023-11-21

• Added testing utilities: fix, fixException, mock and unmock.
• Detect cyclic .uses.
• Added .prev to get the previous value of a data source.
• Assert that running computations a second time returns the same result as the first to try to detect side effects.
• Computations now unsubscribe from abandoned dependencies.
• Allow data sources to pass errors to computations.
• Defined a public API for listeners.

0.0.1 - 2023-11-15
