paste is a minimalist, dependency-free JavaScript toolkit originally created in 2011 to power high-performance webviews inside early iPhone applications. It is the foundational layer of PasteStack.
- ES modules —
paste-esm.jsprovides nativeimport/exportsupport - Mocha/Chai test runner replaces Jest
- UI widgets removed — heroscroll, stickynav, autogrow, etc. moved to paste-elements
- Project restructure — npm removed in favor of project-level structure
See RELEASE_NOTES.md for full details.

paste is the foundation of PasteStack. UI components, asset pipeline, and surface rendering build on top:
paste ← you are here (core JS utilities)
paste-elements ← JS/SCSS UI components (YUI-style modules)
paste-assetgraph ← Rust pipeline: bundles + manifest.json
paste-surface-* ← templates, ViewModels, asset injection
- Provide the smallest possible set of utilities to build real applications fast
- Direct DOM and event operations over heavy abstractions
- Cross-platform: works in browsers, webviews, and server-rendered contexts
- Zero dependencies, ~11k/8k gzipped
