Having a text file (underscore templates) loaded by require.js on initial app start:

define([\'text!templates/template.html\'], function(Template){ ... };

RequireJS is not designed for reloading modules, generally speaking.

However, if you design your application carefully you can get RequireJS to reload some modules. Here's an example:

<body>
  <p id="contents">Nothing loaded.</p>
  <button id="reload">Reload</button>
  <script>
    require.config({
        baseUrl: "./js",
        paths: {
            jquery: '//cdnjs.cloudflare.com/ajax/libs/jquery/2.0.3/jquery.min',
        }
    });
    require(["jquery"], function ($) {
        var $contents = $("#contents");
        function reload() {
            require.undef("text!../file.html");
            require(["text!../file.html"], function (file) {
                $contents.empty();
                $contents.append(file);
            });
        }
        $("#reload").click(reload);
    });
  </script>
</body>


The key is to call require.undef to undefine the module before reloading it.

I've got a repo illustrating the whole thing. If you edit the file.html file and hit the "Reload" button, the text of the paragraph will be replaced with the contents of the file. To get a function you can invoke form the console just assign it to a field of window (e.g. window.reload).

The button should really be called Load/Reload (because it does the initial loading and the reloading) but I'm not going to fix it.
