scan-type v1.0.0

scan-type

A simple, comprehensive and lightweight type-checking library for JavaScript.

Most type-checking libraries are compatible with 10 or 20 types. This library offers 50+. But, once minified, the library is still only 3KB in size.

Here's a quick example:

const {
  isNumber,
  isFloat,
  isString,
  isArray,
  isPromise,
  isWeakMap,
  isGenerator,
  isDataView,
  isAsyncFunction,
  isInfinite
} = require('scan-type');

isNumber(1); // true
isFloat(1.5); // true
isString('abc'); // true
isArray(new Array()); // true
isPromise(new Promise(resolve => resolve())); // true
isWeakMap(new WeakMap()); // true
isGenerator((function*() {})()); // true
isDataView(new DataView(new ArrayBuffer())); // true
isAsyncFunction(async function() {}); // true
isInfinite(-Infinity); // true

Install

Using npm:

npm i scan-type
