🐉 Usage

• Please use npm/yarn install this package

npm i typest --save
# or
yarn i typest --save

Usage in Vue

// in main.js：
Vue.prototype.$type = require('typest');
// use
this.$type.is([], 'Array')
// true

• import or require what you need

// in node.js
const typest = require('typest')
typest.isWindow(window)
// false
typest.isWindow(null)
// false
typest.isWindow('')
// false

// in frontend
import { isWindow } from 'typest'

isWindow(window)
// true
isWindow(null)
// false
isWindow('')
// false

"is"

• Example 1: Base on call()ing constructor
• 方法一： 基本数据类型判断，基于构造类名判断

import { is } from 'typest'

is(123, 'Number')
// true
is(null, 'Null')
// true
is(null, 'Object')
// false
is([], 'Array')
// true
is([], 'Object')
// false
is('', 'String')
// true
is(new Set(), 'Set')
// true

• Example 2: Using constructor directly.
• 方法二： 通过判断constructor

const arr = [1,2,3]
console.log(arr.constructor === Array)
// true
console.log(new Set().constructor === Set)
// true

"isServer"

• 判断当前环境是不是服务端
• Check if this is server side.
• type: Boolean
• value: true or false

// 在Nodeh环境执行
// execute in Node env
console.log(typest.isServer)
// true

// 在浏览器环境执行
// execute in Broswer env
console.log(typest.isServer)
// false

"isClient"

• 判断当前环境是不是客户端，与isServer互相对立
• If current env is Client, is the opposite of isServer
• type: Boolean
• value: true or false

// 在Nodeh环境执行
// execute in Node env
console.log(typest.isClient)
// false

// 在浏览器环境执行
// execute in Broswer env
console.log(typest.isClient)
// true

"isNumber"

// in node.js
const typest = require('typest')
typest.isNumber(NaN)
// true
typest.isNumber(123)
// true
typest.isNumber(null)
// false
typest.isNumber('')
// false

import { isNumber } from 'typest'

isNumber(123)
// true
isNumber(null)
// false
isNumber('')
// false

"isObject"

import { isObject } from 'typest'

isObject(123)
// false
isObject(null)
// true
isObject({a: 234})
// true
isObject('')
// false

"isEmpty"

import { isEmpty } from 'typest'

isEmpty(123)
// false
isEmpty({})
// true
isEmpty([])
// true
isEmpty('')
// true
