ES6 Modules</h1> <p> The GoJS kit contains examples of using GoJS with ES6 modules. </p> <h2 id="GoJSDirectly">Using GoJS as an ES6 module</h2> <p> By default the GoJS library does not use the <code>export</code> keyword, for compatibility reasons. So we have had to provide different libraries that are ES6 modules. In the <code>release</code> folder, they are the <code>go-module.js</code> and <code>go-debug-module.js</code> libraries. In addition, there is an ES6 module-specific TypeScript definition file: <code>go-module.d.ts</code>. </p> <p> In <code>samplesTS</code>, the <a href="../samplesTS/minimalModule.html">minimalModule.html</a> sample uses ES6. It references: </p> <pre class="lang-ts"><code>import * as go from '../release/go-module.js';</code></pre> <p>In order to load GoJS and other ES6 modules, the HTML page also uses the <code>type="module"</code> script tag:</p> <pre class="lang-html"><code>  <script type="module"> import { init } from "./minimalModule.js"; // lib needs: export const go = self.go; window.onload = function() { init(); } </script> </code></pre> <p> Most browsers will not display resources with <code><script type="module"></code> if they are served from a local file system, so you may need to open <code>minimalModule.html</code> from a server to see the results on localhost:. </p> <h2 id="GoJSES6">GoJS Extensions as ES6 Modules</h2> <p> The extension classes can also be loaded as ES6 modules if you modify the <code>tsconfig.json</code> configuration in the <code>extensionsTS</code> folder, and then rebuild. </p> <pre class="lang-json"><code> { "compilerOptions": { "target": "es6", "strict": true } }</code></pre> <p> Recompiling those TypeScript classes will then produce module-friendly JS libraries. </p> <p> Depending on your toolchain, you could also include compiler options directly into your project, as is done in the <a href="https://github.com/NorthwoodsSoftware/GoJS-projects/tree/master/vue-webpack">vue-webpack GoJS project</a>. In its <code>webpack.config.js</code> file, we specify new compiler options for the TypeScript loader so that Webpack + Vue compiles the extensions with ES6 module support instead of the <code>extensionsTS</code> defaults. </p> <pre class="lang-json"><code> /* ... in webpack.config.ts in the vue-webpack project ... */ // files with `.ts` or `.tsx` extension will be handled by `ts-loader` { test: /\.tsx?$/, loader: 'ts-loader', options: { // We want to override the tsconfig file currently in: // vue-webpack\node_modules\gojs\extensionsTS // Because it uses ES5 + umd modules and we want to use ES6 + ES6. compilerOptions: { "module": "ES6", "target": "ES6", "noImplicitAny": true } }</code></pre> <h2 id="GoJSRequireJS">GoJS with <code>RequireJS</code></h2> <p> Both the <code>go.js</code> library and the <code>go-debug.js</code> library can be loaded via <a href="https://requirejs.org/">RequireJS</a>. </p> <p> The <code>extensionsTS</code> directory contains all of the extension classes from the <code>extensions</code> directory, but in TypeScript and pre-compiled as UMD modules. This is reflected in that directory's <code>tsconfig.json</code>: </p> <pre class="lang-json"><code> { "compilerOptions": { "module": "umd", "target": "es5", "strict": true } }</code></pre> <p> The generated JavaScript can then be loaded as UMD modules via <code>require</code>. </p> <pre class="lang-html"><code> <script src="../samples/assets/require.js"></script> <script id="code"> function init() { require(["CheckBoxesScript"], function (app) { app.init(); }); } </script></code></pre> <h2 id="GoJSWithES6Modules">GoJS with ES6 Modules</h2> <p> The GoJS library is available as an ES6/JavaScript module at <code>release/go-module.js</code>. A debug version is also available: <code>release/go-debug-module.js</code>. </p> <p> Samples and extension classes as modules are in the <code>extensionsJSM</code> directory. These include the modules directly using the <code>type="module"</code> <code>script</code> tag. For example, in the sample <a href="../extensionsJSM/LinkLabelDragging.html">LinkLabelDragging</a>: </p> <pre class="lang-html"><code> <script type="module" id="code"> import * as go from "../release/go-module.js"; import { LinkLabelDraggingTool } from './LinkLabelDraggingTool.js'; const $ = go.GraphObject.make; const myDiagram = $(go.Diagram, 'myDiagramDiv', ...); // install the LinkLabelDraggingTool as a "mouse move" tool myDiagram.toolManager.mouseMoveTools.insertAt(0, new LinkLabelDraggingTool()); </script> </code></pre> </div > </div> </div> <div class="bg-nwoods-primary"> <section class="max-w-screen-lg text-white container mx-auto py-2 px-12"> <p id="version" class="leading-none mb-2 my-4">GoJS</p> </section> </div><footer class="bg-nwoods-primary text-white"> <div class="container max-w-screen-lg mx-auto px-8"> <div class="w-full py-6"> <div class="max-w-screen-lg xl:max-w-screen-xl mx-auto px-4 sm:px-6 md:px-8"> <ul class="text-sm font-medium pb-14 sm:pb-20 grid grid-cols-1 sm:grid-cols-3 gap-y-10"> <li class="list-none row-span-2"> <h2 class="text-base font-semibold tracking-wide">GoJS</h2> <ul class="list-none space-y-4 md:space-y-1 px-0"> <li> <a href="../samples/index.html">Samples</a> </li> <li> <a href="../learn/index.html">Learn</a> </li> <li> <a href="../intro/index.html">Intro</a> </li> <li> <a href="../api/index.html">API</a> </li> <li> <a href="../changelog.html">Changelog</a> </li> <li> <a href="https://github.com/NorthwoodsSoftware/GoJS">GitHub</a> </li> </ul> </li> <li class="list-none row-span-2"> <h2 class="text-base font-semibold tracking-wide">Support</h2> <ul class="list-none space-y-4 md:space-y-1 px-0"> <li> <a href="https://www.nwoods.com/contact.html" target="_blank" rel="noopener" onclick="getOutboundLink('https://www.nwoods.com/contact.html', 'contact');">Contact</a> </li> <li> <a href="https://forum.nwoods.com/c/gojs">Forum</a> </li> <li> <a href="https://www.nwoods.com/app/activate.aspx?sku=gojs">Activate</a> </li> <li> <a href="https://www.nwoods.com/sales/index.html" target="_blank" rel="noopener" onclick="getOutboundLink('https://www.nwoods.com/sales/index.html', 'buy');">Buy</a> </li> <li> <a href="https://www.youtube.com/channel/UC9We8EoX596-6XFjJDtZIDg">Videos</a> </li> </ul> </li> <li class="list-none row-span-2"> <h2 class="text-base font-semibold tracking-wide">Company</h2> <ul class="list-none space-y-4 md:space-y-1 px-0"> <li> <a href="https://www.nwoods.com">Northwoods</a> </li> <li> <a href="https://www.nwoods.com/about.html">About Us</a> </li> <li> <a href="https://www.nwoods.com/contact.html">Contact Us</a> </li> <li> <a href="https://twitter.com/northwoodsgo">Twitter</a> </li> </ul> </li> </ul> <p class="text-sm text-gray-100 md:mb-6"> Copyright 1998-2021 <a class="text-white" href="https://www.nwoods.com">Northwoods Software</a> </p> </div> </div> </footer> </body> <script async src="https://www.googletagmanager.com/gtag/js?id=UA-1506307-5"></script> <script> window.dataLayer = window.dataLayer || []; function gtag(){dataLayer.push(arguments);} gtag('js', new Date()); gtag('config', 'UA-1506307-5'); var getOutboundLink = function(url, label) { gtag('event', 'click', { 'event_category': 'outbound', 'event_label': label, 'transport_type': 'beacon' }); } // topnav var topButton = document.getElementById("topnavButton"); var topnavList = document.getElementById("topnavList"); topButton.addEventListener("click", function() { this.classList.toggle("active"); topnavList.classList.toggle("hidden"); document.getElementById("topnavOpen").classList.toggle("hidden"); document.getElementById("topnavClosed").classList.toggle("hidden"); }); </script> <script src="../assets/js/prism.js"></script> <script src="../release/go.js"></script> <script src="../assets/js/goDoc.js"></script> <script> document.addEventListener("DOMContentLoaded", function() { if (window.go) document.getElementById('version').textContent = "GoJS version " + go.version; if (window.goDoc) window.goDoc(); var d = window.diagrams; for (var i = 0; i < d.length; i++) { var dargs = d[i]; goCodeExecute(dargs[0], dargs[1], dargs[2], dargs[3], dargs[4]); } if (window.extra) window.extra(); }); </script> </html>
