ts-cliche-unions

A module for writing JavaScript cliché strings safely in TypeScript.
It provides string constants for key, event, HTML element, and HTML attributes.
This module does not use enums, so unnecessary code is reduced by treeshaking when compiled.

Install

npm install ts-cliche-unions --save

Usage

Import this module into your TypeScript file.

import { KEY } from 'ts-cliche-unions';

This module can be used to replace key name strings, etc., with constants.

// if(ev.key === 'Enter') { ... }
if(ev.key === KEY.Enter) { ... }

// document.addEventListener('copy', (e) => { ... }  
document.addEventListener(EVENT.Copy, (e) => { ... }  

// const link = document.createElement("a");  
const link = document.createElement(ELEMENT.A);

// element.setAttribute('class','test');
element.setAttribute(ATTRIBUTE.Class, 'test');

Specification Notes

The library provides not only constants but also union types for constants, but the types support only alphabetic characters.
Be careful when using the library's union type for variables that may contain any character.

If you just want to use constants, don't worry about the above.
