utility-ts

A collection of helpful utilities for Typescript projects.

Utilities

Buffer Helper

Converts various types of arrays, strings and numbers to a buffer.

    const stringBuffer = await BufferHelper.toBuffer('Hello World');

Clone Helpers

An extremely fast function for deep-cloning an object which only contains simple values, i.e. primitives, arrays and nested simple objects.

const foo = {
 prop1: 'hello',
 prop2: 'world',
}

const bar = CloneHelper.simpleDeepClone(foo);

console.assert(foo === bar);

Common Helpers

A collection of general use guards such as.

• isObject
• isClassInstance
• notNullOrUndefined
• assertNever

Generic Helper

Provides a .NetCore style Activator to instantiate generic types at runtime.

Iterator Helpers

Methods to repeat functions multiple times.

Map Helper

FastFlatMap provides same result as FlatMap in the es2019 standard but 40% quicker.

const obj = {
 boringProp: 123,
 goodProp: 'abc',
 nestedProp: {
   boringProp: 456,
   goodProb: 'def'
 }
}

MapHelper.FastFlatMap(obj, 'goodProp');

this will result in

const result = [
 {
   goodProp: 'abc',
 },
 {
   goodProp: 'def',
 }
]

Number helper

Assortment of number formatting functions.

Object helper

Assortment of object functions for merging, flattening, serialising, sorting.

Observable helper

Helper to convert observables to promises.

String helper

Assortment of object functions for merging, flattening, serialising, sorting.

Typed Array helper

Assortment of helpers to detect types of TypedArrays as well as converting them to buffers
