@swim/constraint

package documentation chat

@swim/constraint implements an incremental solver for systems of linear layout constraints. @swim/constraint is part of the @swim/ui framework.

Installation

npm

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

Browser

Browser applications can load swim-ui.js—which bundles the @swim/constraint 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/constraint 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/constraint can be imported as an ES6 module from TypeScript and other ES6-compatible environments.

import * as constraint from "@swim/constraint";

CommonJS/Node.js

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

var constraint = require("@swim/constraint");

Browser

When loaded by a web browser, the swim-ui.js script adds all @swim/constraint 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/constrain 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.

You can’t perform that action at this time.
