@swim/dom

@swim/dom provides CustomEvent and ResizeObserver polyfills. @swim/dom is part of the @swim/ui framework.

Installation

npm

For an npm-managed project, npm install @swim/dom to make it a dependency. TypeScript sources will be installed into node_modules/@swim/dom/main. Transpiled JavaScript and TypeScript definition files install into node_modules/@swim/dom/lib/main. And a pre-built UMD script can be found in node_modules/@swim/dom/dist/main/swim-dom.js.

Browser

Browser applications can load swim-ui.js—which bundles the @swim/dom library—along with its swim-core.js dependency, directly from the swimOS CDN.

<!-- Development -->
<script src="https://cdn.swimos.org/js/latest/swim-core.js"></script>
<script src="https://cdn.swimos.org/js/latest/swim-ui.js"></script>
 
<!-- Production -->
<script src="https://cdn.swimos.org/js/latest/swim-core.min.js"></script>
<script src="https://cdn.swimos.org/js/latest/swim-ui.min.js"></script>

Alternatively, the standalone swim-system.js script may be loaded from the swimOS CDN, which bundles @swim/dom together with all other @swim/system libraries.

<!-- Development -->
<script src="https://cdn.swimos.org/js/latest/swim-system.js"></script>
 
<!-- Production -->
<script src="https://cdn.swimos.org/js/latest/swim-system.min.js"></script>

Usage

ES6/TypeScript

@swim/dom can be imported as an ES6 module from TypeScript and other ES6-compatible environments.

import * as dom from "@swim/dom";

CommonJS/Node.js

@swim/dom can also be used as a CommonJS module in Node.js applications.

var dom = require("@swim/dom");

Browser

When loaded by a web browser, the swim-ui.js script adds all @swim/dom library exports to the global swim namespace. The swim-ui.js script requires that swim-core.js has already been loaded.

The swim-system.js script also adds all @swim/dom library exports to the global swim namespace, making it a drop-in replacement for 'swim-core.js' and swim-ui.js when additional @swim/system libraries are needed.
