Set of shortands of Object.prototype.toString
for simple type check. Need to fast and basic type check of some data and don't want to include heavy libraries? You are welcome. Here is only few lines of code. In case if you need more complex data check - that set isn't what you looking for. Try to take a look to Schema, lodash and others.
Набор сокращений Object.prototype.toString
для простой проверки типов. Нужна быстрая и простая проверка типа и не хочется подключать тяжелые комбайны? Эта библиотека именно то, что вам нужно. Если вам нужна более тщательная и сложная проверка данных - этот набор не то, что вы ищета. Попробуйте взглянуть на Schema, lodash или другие аналоги.
Install
npm i @voidvolker/is
No any additional dependencies is used.
Use
ES module:
import {
isBoolean,
isNumber,
isString,
isArray,
isObject,
isFunction,
typeGet
} from '@voidvolker/is'
console.log(isBoolean(true)
console.log(isString('string'))
console.log(typeGet([]))
Require:
const {
isBoolean,
isNumber,
isString,
isArray,
isObject,
isFunction,
typeGet
} = require('@voidvolker/is') // -> dist/commonjs/is.cjs
console.log(isBoolean(true)
console.log(isString('string'))
console.log(typeGet([]))
Coffee script:
import {
isBoolean
isNumber
isString
isArray
isObject
isFunction
typeGet
} from '@voidvolker/is'
console.log isBoolean true
console.log isString 'string'
console.log typeGet []
Exports
isBoolean(v)
isNumber(v)
- Excludes NaN, includesNumber()
type and InfinityisString(v)
isArray(v)
->Array.isArray
isObject(v)
isFunction(v)
typeGet(v)
- returns string with string likeBoolean
,Number
and etc. Warning! Useless for NaN:typeGet(NaN) === 'Number'
Exactly types checks
Run command to get full report for each value type results:
npm i -D
npm test
Details can be found in test/is.spec.coffee
file.
Dev
To update dependencies use ncu
module.
Build
npm run build
rollup
and babel
is used for bundling and transforming code for browsers. Take a look to dist folder and take what you need.
Only compile coffee:
npm run make
Test
npm test
And command to watch tests in realtime:
npm run wt
Watch
npm run w
