    HTML5 Placeholder jQuery Plugin

    HTML5 Placeholder jQuery Plugin

    A jQuery plugin that enables HTML5 placeholder behavior for browsers

    HTML5 Placeholder jQuery Plugin is a jQuery plugin that enables HTML5 placeholder behavior for browsers that aren’t trying hard enough yet. You’ll still be able to use jQuery.val() to get and set the input values. If the element is currently showing a placeholder, .val() will return an empty string instead of the placeholder text, just like it does in browsers with a native @placeholder implementation. Calling .val('') to set an element’s value to the empty string will result in the placeholder text (re)appearing. The plugin automatically adds class="placeholder" to the elements that are currently showing their placeholder text. You can use this to style placeholder text differently.

    HTMLMinifier

    HTMLMinifier

    Javascript-based HTML compressor/minifier (with Node.js support)

    HTMLMinifier is a highly configurable, well-tested, JavaScript-based HTML minifier. Minifier options like sortAttributes and sortClassName won't impact the plain-text size of the output. However, they form long repetitive chains of characters that should improve compression ratio of gzip used in HTTP compression. SVG tags are automatically recognized, and when they are minified, both case-sensitivity and closing slashes are preserved, regardless of the minification settings used for the rest of the file. HTMLMinifier can't work with invalid or partial chunks of markup. This is because it parses markup into a tree structure, then modifies it (removing anything that was specified for removal, ignoring anything that was specified to be ignored, etc.), then it creates a markup out of that tree and returns it.

    Prerender SPA Plugin

    Prerender SPA Plugin

    Prerenders static HTML in a single-page application

    Flexible, framework-agnostic static site generation for sites and SPAs built with webpack. This is the stable 3.x version of prerender-spa-plugin based on puppeteer. If you're looking for the (now-deprecated) 2.x version, based on PhantomJS, take a look at the v2 branch. The goal of this plugin is to provide a simple prerendering solution that is easily extensible and usable for any site or single-page-app built with webpack. Plugins for other task runners and build systems are planned. Framework-specific examples can be found in the examples/ directory. Most usages of prerender-spa-plugin v2.x should be compatible with v3.x. The exception being advanced configuration options that controlled PhantomJS. These have been replaced by pluggable renderers with their own specific configuration options.

    A micro HTML/SVG render

    uhtml is a minimal JavaScript library for building fast, reactive HTML and SVG interfaces with standard web platform features. It uses tagged template literals to provide a JSX-inspired syntax without requiring a compiler or specialized build tools. Components can be written as regular functions and connected to reactive state through signals, computed values, effects, batching, and untracked reads. The renderer supports keyed nodes, references, fragments, event handlers, boolean attributes, direct property updates, and object spreading. It also integrates with native custom elements and simplifies accessibility and dataset management through dedicated aria and data attributes. Development builds include runtime diagnostics that help identify malformed templates while production builds remain focused on compact rendering.

    undom

    1kb minimally viable DOM Document implementation

    Minimally viable DOM Document implementation. A bare-bones HTML DOM in a box. If you want the DOM but not a parser, this might be for you. JSFiddle Demo: Rendering preact components into an undom Document. Undom aims to find a sweet spot between size/performance and utility. The goal is to provide the simplest possible implementation of a DOM Document, such that libraries relying on the DOM can run in places where there isn't one available. The intent to keep things as simple as possible means undom lacks some DOM features like HTML parsing & serialization, Web Components, etc. These features can be added through additional libraries. One task undom doesn't handle for you by default is HTML serialization. A proper implementation of this would be cumbersome to maintain and would rely heavily on getters and setters, which limits browser support. Below is a simple recipe for serializing an undom Element (Document, etc) to HTML.
