Description

Sometimes there is a need to know what a value's type of something is, this package exists to satisfy those needs by implementing a parser that can retrieve the type of the value recursively and process a string similar to TypeScript's types.

Features

• Written in TypeScript
• Bundled with Rollup so it can be used in NodeJS and browsers
• Offers CommonJS, ESM and UMD bundles
• Fully tested

Installation

yarn add @sapphire/type
# npm install @sapphire/type

Usage

Note: While this section uses require, the imports match 1:1 with ESM imports. For example const { Type } = require('@sapphire/type') equals import { Type } from '@sapphire/type'.

Note: When using ESM syntax you can also default-import Type class: import Type from '@sapphire/type'.

Note: The internal functions of getPromiseDetails and getProxyDetails are also exported. If you don't know what these are, then you need not be concerned about this.

Basic Usage

// Import the Type class
const { Type } = require('@sapphire/type');

// Define a Type with an array of two numbers
const type = new Type([1, 2]);

console.log(type.toString());
// Logs: Array<number>
