param-type NPM version

Speed and accuracy - that is what param-type offers. Thanks to multiple benchmarks it is as fast as it is possible! Unit tests make sure that each case is checked and works as intended.

Install

Install with npm:

$ npm install --save param-type

Why use this instead of kind-of?

  1. it's faster
  2. even better type checking
import paramType from 'param-type';
or
const paramType = require('param-type').default;

paramType(undefined); //=> 'undefined'

paramType(null); //=> 'null'

paramType(true); //=> 'boolean'

paramType(false); //=> 'boolean'

paramType(new Buffer('')); //=> 'buffer'

paramType(42); //=> 'number'

paramType('str'); //=> 'string'

paramType(arguments); //=> 'arguments'

paramType({}); //=> 'object'

paramType(Object.create(null)); //=> 'object'

paramType(new Test()); //=> 'object'

paramType(class Test {}); //=> 'class'

paramType(new Date()); //=> 'date'

paramType([1, 2, 3]); //=> 'array'

paramType(/foo/); //=> 'regexp'

paramType(new RegExp('foo')); //=> 'regexp'

paramType(new Error('error')); //=> 'error'

paramType(new TypeError('error')); //=> 'TypeError'

paramType(function () {}); //=> 'function'

paramType(function * () {}); //=> 'generatorfunction'

paramType(Symbol('str')); //=> 'symbol'

paramType(new Map()); //=> 'map'

paramType(new WeakMap()); //=> 'weakmap'

paramType(new Set()); //=> 'set'

paramType(new WeakSet()); //=> 'weakset'

paramType(new Int8Array()); //=> 'int8array'

paramType(new Uint8Array()); //=> 'uint8array'

paramType(new Uint8ClampedArray()); //=> 'uint8clampedarray'

paramType(new Int16Array()); //=> 'int16array'

paramType(new Uint16Array()); //=> 'uint16array'

paramType(new Int32Array()); //=> 'int32array'

paramType(new Uint32Array()); //=> 'uint32array'

paramType(new Float32Array()); //=> 'float32array'

paramType(new Float64Array()); //=> 'float64array'

Better type checking

Returns specific Error (TypeError, ReferenceError) type instead of error

Test

  • Unit tests:
$ npm install && npm test
  • Benchmarking: Import your favourite type checking library in benchmark.ts and add it to test
targets.forEach((target, index) => {
  console.log(`\n${index + 1} of ${targets.length};`, `paramType: ${paramType(target)}`, target);
  new Suite()
    .add("typeOf", () => {
      paramType(target);
    })
    .add(Your library name, () => {
      Your_library(target);
    })
    .on("cycle", (event: Event) => {
      console.log(`${String(event.target)}`);
    })
    .run();
});
