Modular, tree-shakeable browser utilities monorepo. Core clipboard APIs plus idiomatic framework adapters for React, Vue, and Svelte. Zero runtime dependencies, SSR-safe, framework-agnostic.

Why ctc? Modern Clipboard API under the hood, SSR-safe out of the box, TypeScript-native with zero any, multi-framework adapters that share a zero-dependency core, and fully tree-shakeable. See full comparison →

All functions are SSR-safe -- safe to import in Next.js, Nuxt, or any server-side environment without crashing.

import { copyToClipboard, isClipboardSupported } from '@ngockhoi96/ctc/clipboard'

button.addEventListener('click', async () => {
  if (isClipboardSupported()) {
    const success = await copyToClipboard('Hello, world!')
    console.log(success ? 'Copied!' : 'Copy failed')
  }
})

For framework-idiomatic usage, see the React, Vue, or Svelte package README linked above. For the full API reference (all five functions, error codes, options), see packages/core/README.md.

Built with pnpm workspaces + Turborepo. See CONTRIBUTING.md for setup.

All functions require ES2020+ (>95% global browser support).

All functions are SSR-safe and will return false or null when called in a server-side environment (Node.js, Deno, Bun) without crashing.

The following libraries solve clipboard operations in similar or overlapping ways. Listed here for reference — see BENCHMARKS.md for a detailed comparison table.

• clipboard-copy — Minimal clipboard write utility using the modern Clipboard API with execCommand fallback. Last updated 2020.
• copy-to-clipboard — Clipboard write utility with broad browser support via execCommand. Last updated 2022.

• react-copy-to-clipboard — Render-prop React component for clipboard copy operations.
• usehooks-ts useClipboard — Clipboard hook included in the usehooks-ts multi-utility collection. TypeScript-native.
• react-use useClipboard — Clipboard hook included in the react-use multi-utility collection.

• @vueuse/core useClipboard — Clipboard composable included in the VueUse collection of Vue 3 utilities. TypeScript-native.

The Svelte clipboard ecosystem is sparse. The Svelte docs show how to write a clipboard action natively; no widely-maintained dedicated library exists as of 2026.
