@trz/type

A tool for real type validate.

Install

npm install @trz/type

# Or

yarn add @trz/type

Usage

Import

// ES6
import types, {of, is} from '@trz/type';

// nodejs or broswer
const types  = require('@trz/type');

Interface

function of(source: any): string;

• Enter an element of any type and return the real type for the element in JavaScript.

• Example:

  import types from '@trz/type';
  
  types.of(123456789)              //>>> number
  
  types.of('this is a string')     //>>> string
  
  types.of([])                     //>>> array
  
  types.of({})                     //>>> object

function is(source: any, assert: string): boolean

• Compare whether the source type is the specified type.

• Example:

  import types from '@trz/type';
  
  types.is([], 'array')              //>>> true
  
  types.is([], 'object')             //>>> false
  
  types.is('123456789', 'string')    //>>> true
  
  types.is(null, 'string')           //>>> false

function some(source: any, asserts: string[]): boolean

• Verify that the specified element contains the specified type.

• Example:

  import types from '@trz/type';
  
  types.some([1, 2], ['array', 'object'])      //>>> true
    
  types.some([1, 2], ['object', 'string'])     //>>> false
    
  types.some('1239', ['string'])               //>>> true
    
  types.some(null, ['string'])                 //>>> false

function isInteger(source: any): boolean

• Verify that the source is an integer type

• Example:

  import { isInteger } from '@trz/type';
  
  isInteger(12345678)          //>>> true
  
  isInteger(12345.00)          //>>> true
  
  isInteger(0.123456)          //>>> false
  
  isInteger(1.234567)          //>>> false
  
  isInteger('12345678')        //>>> true
  
  isInteger('12345.00')        //>>> true
  
  isInteger('0.123456')        //>>> false
  
  isInteger('1.234567')        //>>> false
  
  isInteger('string')          //>>> false
  
  isInteger([])                //>>> false
