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 |
