# Typed-Patterns Basic design patterns for TypeScript. [Documentation](https://kol-93.github.io/typed-patterns) _This project is under development and may make breaking changes in minor versions until 1.0._ ## Installation ```bash npm install typed-patterns ``` ## Patterns ### Behavioral * Synchronous and asynchronous **chain-of-responsibility**. See examples in `source/examples/behavioral/chain-of-responsibility` ## Utilities ### Asynchronous helpers * `success(callback, ...result)` calls specified callback as successful with array of results * `fail(callback, error)` calls specified callback as failed with specified error * `join(onSuccess, onError)` builds classical callback function from two success-callback and error-callback * `wrapCallback(callback)` builds callback function that wraps array of success results into single tuple * `unwrapCallback(callback)` builds callback function that unwraps single tuple to an array of success results * `wrapWorker(worker)` builds asynchronous worker function that wraps array of results into single tuple * `unwrapWorker(worker)` builds asynchronous worker function that unwraps single result to an array of results * `collect(workersCollection)` builds asynchronous worker that collects results from all passed workers * `guardAsyncProcessor(guard, processor)` builds asynchronous processor responsible only for type-guarded context ### Promise helpers * `guardPromiseProcessor(guard, processor)` builds asynchronous processor responsible only for type-guarded context ### Unexpected context exception helpers * `class Unexpected` Base class of unexpected context exception * `unexpected(message?, callback?, next?)` Calls next (if specified) or passes Unexpected exception to callback (if specified)
