TS Mortar

Dependencies: none

Utility functions for common TypeScript string, array, object, and enum operations. Similar to lodash or underscore, these functions are the result of needs I've encountered in Javascript/TypeScript projects over the last few years. See the /test directory for example usage of the functions.

Arrays

Includes functions for manipulating an array like a list:

• addAll(), addAllTransform()
• hasAny(), isOneItem()
• binarySearch()
• containsAll(), containsAny()
• diff()
• distinct()
• fastRemove(), fastRemoveIndex()
• filterSplit()
• first(), firstIndex()
• last(), lastIndex()
• map(), mapFilter(), mapFilterNotNull()
• removeAll()
• removeIndex()
• removeValue()
• sortNumeric()
• swap()
• toMap()
• groupBy()
• union()
• max(), min(), sum() Comparison:
• equal()
• looseEqual()
• unique()
• diff()
• filterSplit() Object searching:
• firstProp()
• pluck()
• indexOfProp(), lastIndexOfProp()
• setAllProp()

Functions

Wrap functions to provide additional functionality, such as checking if a function is null before calling it, catching errors thrown by a function, timing how long a function takes to run, etc.:

• applyFunc()
• callFunc()
• createFuncTimer()
• tryCatch()
• lazyField()
• partial()

EnumCreator

Create TypeScript enum objects similar to Java enums:

• initEnumClass()

Numbers

Focused around converting numbers to and from a user displayable format:

• isNumeric()
• isNullOrZero()
• toNumber()
• roundTo()
• toFixed()
• format()

Objects

Copying objects and getting/checking/transforming properties:

• assign(), assignNonUndefined()
• clone(), cloneDeep(), cloneDeepNonUndefined()
• extendPrototype(), extendToStatic()
• hasMatchingProps(), hasNonNullProps(), ...
• invert()
• map()
• toArray()
• values()

Strings

Basic string validation, trimming, truncating, and replacing:

• truncate()
• padStart(), padEnd()
• removeLeading(), removeTrailing()
• isNullOrEmpty(), isNullOrWhiteSpace()
• isCharAtDigit(), isCharAtLowerCase(), isCharAtUpperCase()
• replaceAll()
