@swim/length
@swim/length implements DOM-relative length types with unit-aware algebraic operators, conversions, and parsers. @swim/length is part of the @swim/ui framework.
Installation
npm
For an npm-managed project, npm install @swim/length to make it a dependency.
TypeScript sources will be installed into node_modules/@swim/length/main.
Transpiled JavaScript and TypeScript definition files install into
node_modules/@swim/length/lib/main. And a pre-built UMD script can
be found in node_modules/@swim/length/dist/main/swim-length.js.
Browser
Browser applications can load swim-ui.js—which bundles the @swim/length
library—along with its swim-core.js dependency, directly from the swimOS CDN.

from the swimOS CDN, which bundles @swim/length together with all other
@swim/system
libraries.

ES6/TypeScript
@swim/length can be imported as an ES6 module from TypeScript and other ES6-compatible environments.
import * as length from "@swim/length";CommonJS/Node.js
@swim/length can also be used as a CommonJS module in Node.js applications.
var length = require("@swim/length");Browser
When loaded by a web browser, the swim-ui.js script adds all
@swim/length 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/length 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.
