Modules

• UtilityModule, that needs to import in order to use the library.

Pipes

All pipes are standalone pipes.

ArrayFilter

<T extends string | number | boolean> transform(
  value: T[], 
  filterBy?: string | number | boolean
): (string | number | boolean)[] { ... }

Use on array of string, number or boolean items, and needs an optional argument of type string, number or boolean. If no argument provided, it will return the same array.

Example:

{{ [0, 'test', false, 100, 'texts'] | arrayfilter }} // [0, 'test', false, 100, 'texts']
{{ [0, 'test', false, 100, 'texts'] | arrayfilter:'te' }} // ['test', 'texts']

ArrayFrom

transform(length: number, fill?: number): number[] { ... }

Use on a number, and needs an optional argument of type number. If no argument provided, it will return an array with index as value.

Example:

{{ 5 | arrayFrom }} // [0, 1, 2, 3, 4]
{{ 5 | arrayFrom:10 }} // [10, 10, 10, 10, 10]

ArrayPluck

transform(
    value: Array<Record<string | number, any>>,
    key: (string | number)
  ): Array<any> { ... }

Use on array of object items, and needs an argument of type number or string.

Example:

{{ [{ a: 1, b: 5 }, { a: 2, c: 4 }, { a: true, b: 'test', c: {} }] | arrayPluck:'b' }} // [5, 'test']
{{ [{ a: 1, b: 5 }, { a: 2, c: 4 }, { a: true, b: 'test', c: {} }] | arrayPluck:'a' }} // [1, 2, true]

CapitalCase

transform(value: string): string { ... }

Use on string.

Example:

{{ 'Lorum ipsum' | capitalCase }} // 'Lorum Ipson'

CoerciveBoolean

transform(value?: any): boolean { ... }

Use on any type.

Example:

{{ undefined | coerciveBoolean }} // true
{{ null | coerciveBoolean }} // false
{{ 'true' | coerciveBoolean }} // true

ControlErrors

transform(controls: AbstractControl): (string | any)[] { ... }

Use on any AbstractControl type.

Example:

formControl = new FormControl(null, {
  validators: [Validators.required, () => ({ customValidator: 'Custom Error Message in any key name!' })]
});
...
{{ formControl | controlErrors }} // ['This field is required', 'Custom Error Message in any key name!']

ControlValue

transform(value: AbstractControl): any { ... }

Use on any AbstractControl type.

Example:

formGroup = new FormGroup({
  test1: new FormControl('test'), 
  test2: new FormControl(null), 
});
...
{{ formGroup | controlValue }} // { test1: 'test', test2: null }

Initial

transform(value: string, max: number = Infinity): string { ... }

Use on a string, and needs an optional argument of type number. If no argument provided, it will return string with initial of all words.

Example:

{{ 'abc Def Ghi Jkl' | initial }} // 'aDGJ'
{{ 'abc Def Ghi Jkl' | initial:2 }} // 'aD'

IsDate

transform(value: any): boolean { ... }

Use on a string, and needs an optional argument of type number. If no argument provided, it will return string with initial of all words.

{{ 1676808350561 | isDate }} // true
{{ 'Sun Feb 19 2023 13:05:50 GMT+0100 (UTC+01:00)' | isDate }} // true
{{ 'WRONG' | isDate }} // false

ObjectEntries

transform(value: Record<string | number, any>): [string | number, any][] { ... }

Use on a object.

Example:

Same as Object.entries.

ObjectKeys

transform(value: Record<string | number, any>): Array<string> { ... }
