riot/dom-nodes

dom-nodes is a small JavaScript library that helps code answer simple questions about HTML and SVG tags. Questions like: is "img" a self-closing tag? Is "circle" an SVG element? Is "selected" a boolean attribute? Instead of a developer writing these checks from scratch or maintaining their own lists, this package provides ready-made functions that return true or false. The library bundles complete lists of all standard HTML tags, SVG tags, void elements (tags that don't need a closing slash, like "img" or "br"), boolean attributes (like "checked" or "disabled"), and elements that accept a value attribute. It exposes simple functions like isHtml, isSvg, isVoid, isCustom, hasValueAttribute, and isBoolAttribute. You pass in a tag name as a string, and the function tells you what category it falls into. The checks are case-insensitive, so "IMG", "img", and "Img" all work the same way. Someone building a web framework, a templating engine, or a custom UI library would use this. For example, if you are writing code that takes a tag name and needs to generate the right HTML output, you need to know whether to self-close the tag or not. Or if you are building a component system and someone writes "my-component", you need to distinguish that custom element from a standard tag like "div". These are the kinds of decisions this library helps automate. One notable design choice is that the project copies its tag lists directly into its own source code rather than depending on other npm packages at runtime. It credits two existing projects as the source of those lists but avoids pulling them in as dependencies. That keeps the package self-contained and lightweight for what is fundamentally just string matching against known lists.
