Seeking assistance to integrate Dat-GUI with Meteor.js

I am attempting to incorporate Dat-GUI into my meteor project by adding the dat-GUI source in the client/lib folder. Below is my code snippet: 

Template.EditorControllbar.rendered = function () {
    var controllBar = document.getElementById('controllbar'),
        gui, folder, controller;

    // Create GUI
    gui = new dat.GUI({autoPlace:false});
    controllBar.appendChild(gui.domElement);

    // Create folders
    var renderFolder = gui.addFolder('Render'),
    meshFolder = gui.addFolder('Mesh'),
    lightFolder = gui.addFolder('Light'),
    exportFolder = gui.addFolder('Export');

};

Upon running the server, I encounter the following error:

Exception from Deps afterFlush function function: ReferenceError: dat is not defined
    at Object.Template.EditorControllbar.rendered (http://localhost:3000/client/views/toons/toon_edit/editor_controllbar/editor_controllbar.js?5613eb3f7dfe2c5aed33925dfe2970dcc11a04b4:33:15)
    at http://localhost:3000/packages/ui.js?9419ac08328918a04e7a49464a988d45f851e1b0:439:23
    at _assign.flush (http://localhost:3000/packages/deps.js?4a82362ae66e863a1c1a8b0a5fec6f665e2038d1:348:13) debug.js:4

Interestingly, the same code functions correctly on Codepen: http://codepen.io/praneybehl/pen/DabKv

If anyone has insight on how to successfully load Dat-GUI with Meteor, your assistance would be greatly appreciated.

Many thanks, Praney

Answer №1

Did you recently include the file https://github.com/dataarts/dat.gui/blob/master/build/dat.gui.min.js in your project's client/lib directory? Remember that Meteor wraps all js files in a function, which means that variables declared with var won't be accessible in other files. To ensure access to the dat variable, it should be added to the client/compatibility folder instead. Files in this particular folder are not wrapped in a function, making the variables global and accessible across multiple files.
