RenderJS

EXTEND NATIVE JS PROTOTYPES, RENDER WITHOUT THE OVERHEAD

npmDownloadsLicense

A JavaScript frontend rendering tool with chainable DOM syntax, a one-shot template engine, and native prototype extensions

Table of Contents

Features

npm i @pardnchiu/renderjs · Documentation

  • Chainable DOM construction — Build real DOM elements from tag-selector strings like "div.card#id"._({...}, [children]), replacing verbose createElement chains.
  • One-shot template engine — RJS offers declarative :if/:for/:model/{{ }} directives that render straight to the DOM in a single pass, with no virtual-DOM diffing; updates are triggered manually via renew(), avoiding the overhead of automatic reactive watching.
  • Native prototype extensions — Adds dozens of chainable methods to String/Array/Object/Element/URL/window (e.g. _child, _class, $req, $shuffle, negative-index access, query-string builders), with no runtime dependency.
  • Built-in lazyload and SVG inlining — _Listener({ lazyload, svg }) enables IntersectionObserver-based image lazy loading and automatic SVG inlining in one line.
  • Zero-dependency, drop-in setup — A single minified dist/RenderJS.js file, installable via npm or a CDN <script> tag, runs directly in the browser.
