asclasit

ASync CLasses + ASync ITerators

Description

This is public-ready spin off from related internal experiments of ClAsync. Advantages of this module:

• 100% test coverage;
• More project files, less file sizes;
• Thin: has no external dependency modules, only core essentials taken from ClAsync and improved;
• Utilizes up-to-date Node.js features;
• Targetting serverless/stateless environments;
• Despite the missing documentation, test cases describe the usage.

Differences

There are architectural differences listed below:

Async Classes

Item	ClAsync	AsClAsIt
Instance co-op	Dependency tree	State isolation
Life cycle	Once (init->final)	Muplitle (...->wake->sleep->...)
Lifetime Methods	init(), final()	(Async) Generator *[$]() depicting whole lifetime
Instance state	Non-configurable [$.inst]	Configurable [$] via static [$]: options object or custom $.Inst subclass
Async Events	Special class (emitter.js)	Automatic for each instance; methods of instance state [$]
Instance Shutdown	Supported (via final)	Not supported (global shutdown handler only for non-stateless environments)

(Async) Iterators

Item	ClAsync	AsClAsIt
Helpers	Functions: $.<name>[Iter|Async](it, ...)	Wrapped chain: $[.Iter|.AsIt|](it).<name>(...).<name>(...)
Extensible Classes	Not supported	Supported for sync ($.Iter) and async ($.AsIt) iterator classes
