IWMBrowser windows are opened with a preload.js which is evaluated before the HTML is loaded. According to <a href="https://electron.atom.io/docs/faq/">"I can not use jQuery/RequireJS/Meteor/AngularJS in Electron"</a> we have to rename the symbols in the page before other libraries are included. In order to access node.js modules we can use `nodeRequire` instead. </p> <p>As a simple test we try to load a file from the filesystem:</p> <script class="doctest"> if (typeof(nodeRequire) != 'undefined') { let fs = nodeRequire('fs') let content = fs.readFileSync('./index.html') let lines = content.toString().split(/\n/) console.log("First line", lines[0] ) Doctest.expect(lines[0], '<html>') } </script> <p>As simple as this test is, it shows that within the IWMBrowser one import all node.js modules. Don't forget to test for nodeRequire to avoid runtime errors in other browsers. </p> <h2> References </h2> <ul> <li><a href="https://electron.atom.io/docs/faq/">I can not use jQuery/RequireJS/Meteor/AngularJS in Electron</a></li> </ul> </main> </body>
