Perfs & Configs

This version brings many minor but necessary bug fixes, performance improvements, and features.

Changed

• createStream() method on Service, Messenger, and ParentThread to accept Record<string | number, any> metadata instead of Record<any, any>.

Added

• More info about metaData to Streaming data between threads section of README.
• Messenger.closed getter.
• Service.setRef() method.
• shareEnv option for task & service workers, defaulting to true + docs.

Fixed

• entries() generator method on SharedMap to be more performant.
• Messenger.closeAll() not closing the current messenger instance.
• Improved general performance for services.
• Improved general performance for task workers & services.
• Incorrect docs for reffed config option. Defaults to true, not false.

Harder, Better, Faster, Stronger

A whole lot of bug fixes & performance/memory efficiency updates in this version.

Fixed

• Not calling getDefaultPoolConcurrency in README example.
• Improved performance for ServiceCluster methods closeAll(), closeAllIdle(), use(), and activeServiceCalls().
• Service.close() not doing early cleanup for callbacks.
• Messenger.close() not doing early cleanup for stream event callbacks.
• define() waiting to run the worker before resolving with the Nanolith API object.
• Missing workerData.identifier property in PoolItemOptions type.
• Service.call() not cleaning up callbacks.
• Service.call() not decreasing active count upon promise rejection.
• Minor performance improvement for Messenger with streams.

Added

• New tests for ServiceCluster.use().

Removed

• ParentThreadTerminateMessageBody type eliminated.

A sink, a weight

Changed

• Some minor refactors.

Added

• SharedMap.entries() method for asynchronously iterating over map keys and values + docs.
• More keywords to package.json.

Fixed

• Task/service calls throwing an error when the worker exits early with exit code 0.
• Some JSDoc typos & unnecessary spaces.
• SharedMap keys containing unnecessary commas that take up extra space.

Removed

• Empty Examples section in README.
• Replaced content in README License section with a link to the license in the GitHub repository.

Pawlished

Changed

• Minor refactors.
• README image.

Added

• ServiceClusterOptions and optional autoRenew option.
• Accept exit codes in the Service.close() and exceptionHandler.terminate() functions.
• SharedMap.delete() method.
• New clause to the license.

Fixed

• SharedMap.get() returning null for non-existent properties, but returning the string of 'null' for existing properties with values set to null.
• Service.call() hanging forever if the underlying task uses process.exit().

Childrens' childrens' children

Changed

• pool to use shared values for the active count and concurrency count, enabling the spawning of new threads from other threads.
• pool to allow for the enqueuing of new items on all threads.
• define() to always return the Nanolith instance, regardless of whether or not it is being run on the main thread.
• Renamed MainThread to ParentThread to match the changes made above + update docs.
• Change "performant" to "scalable" in "About" section in README.
• Renamed all MainThread... message body types to be ParentThread... instead.
• Default max concurrency of pool from 1 thread per core to 2 threads per core + docs update.

Added

• Test for the safeMode option with define().
• getDefaultPoolConcurrency() function exported from root + docs.

Additionally, set up automatic publishing workflow. Any code merged to the main branch gets published. This means no more working on the main branch - it is now strictly for merging/pushing prod-ready code with a bumped version number.

Refactoring & Performance

• Better error handling
• Stable mutex solution for SharedMap

Changed

• Mutex solution for SharedMap to be much more stable
• workerHandler to exit the process with a code of 1 when no type is present on workerData.
• Refactored prepareWritableToPortStream timeout logic.

Removed

• SharedMap.watch functionality + docs.
• Warning in README about parallel operations with SharedMap.

Added

• Throw an error when no task name is provided when running a task worker.

Minor fixes & optimizations

Changed

• Sentence in "Sharing memory between threads" section of the README.
• .current and .changed from getter properties to functions on the SharedMapWatch interface.
• #streamEventCallbacks used by Messenger's Messagable interop to be in a Set instead of an array.
• Various minor performance and memory improvements to SharedMap.
• ServiceCluster.launch to return a tuple of Services when provided with the 1 parameter instead of a single Service. Prevents potential bugs when providing dynamic numbers to the function.

Added

• SharedMapWatch interface with JSDoc documentation for each function.
• Missing "Service properties & methods" section in README table of contents.
• Small warning about SharedMap to the README.

Removed

• Deleted OLD_README.md

The Data Watcher

Changed

• Messenger.transfer to Messenger.raw + renaming of MessengerTransferData type to MessengerRawData
• SharedMap.transfer to SharedMap.raw + renaming of SharedMapTransferData type to MessengerRawData
• Slightly lower bundle size by minimizing the size of the published package.json file.

Fixed

• Minor performance updates for ServiceCluster.

Added

• .watch() method to SharedMap + docs + test
• RemoveListenerFunction return values for .onStream() method on Service, MainThread, and Messenger.
• More tests for service_cluster and streams suites.
• New keywords to the package.json

Minor improvements

Fixed

• Typos in README.
• SharedMap.option only accessible statically and not on instances.

Changed

• MessengerList.list() to be a getter method instead of a regular function. New syntax is MessengerList.list.
• SharedMap.get() to use .subarray() instead of .slice() for a slight memory complexity improvement.
• README logo image to new blue version.
• Improve validation in SharedMap's constructor.
• pool.option back to a regular getter property instead of a static one. Doesn't need to be static.

Added

• New sections to README for properties & methods of Service, ServiceCluster, and pool.
• Tests for streaming with Messenger + a test suite for SharedMap
