@touchspin/core

@touchspin/core

Framework-agnostic TouchSpin logic that powers every renderer. The package exposes ESM-only entry points and ships TypeScript declarations in dist/.

Install

npm install @touchspin/core

Usage

import { TouchSpin } from '@touchspin/core';
import Bootstrap5Renderer from '@touchspin/renderer-bootstrap5';
import '@touchspin/renderer-bootstrap5/css';

TouchSpin(document.querySelector('#quantity'), {
  renderer: Bootstrap5Renderer,
  min: 0,
  max: 100,
  step: 1,
});

TouchSpin attaches the instance directly to the DOM element and returns the API object (methods such as upOnce, downOnce, updateSettings, destroy). Retrieve an existing instance with getTouchSpin(element) when needed.

Exports

• @touchspin/core → dist/index.js (ESM) with dist/index.d.ts
• @touchspin/core/renderer → renderer contracts and base classes (dist/renderer.js, dist/renderer.d.ts)
• package.json is exposed for tooling via exports['./package.json']

Packaging Notes

• sideEffects: false enables tree-shaking for bundlers.
• Supported runtimes: Node 18.17+ (LTS versions 18, 20, 22), evergreen browsers.
• No UMD bundle is produced—load the core through native ESM or a bundler/import map.
