Is it possible to stop requireJS from adding the .js file extension automatically?

Question

I\'m using requireJS to load scripts. It has this detail in the docs:

The path that is used for a module name should not include the .js extension,

Answer 1

I am using requirejs server side with node.js. The noext plugin does not work for me. I suspect this is because it tries to add ?noext to a url and we have filenames instead of urls serverside.

I need to name my files .njs or .model to separate them from static .js files. Hopefully the author will update requirejs to not force automatic .js file extension conventions on the users.

Meanwhile here is a quick patch to disable this behavior.

To apply this patch (against version 2.1.15 of node_modules/requirejs/bin/r.js) :

1. Save in a file called disableAutoExt.diff or whatever and open a terminal
2. cd path/to/node_modules/
3. patch -p1 < path/to/disableAutoExt.diff
4. add disableAutoExt: true, to your requirejs.config: requirejs.config({disableAutoExt: true,});

Now we can do require(["test/index.njs", ...] ... and get back to work.

Save this patch in disableAutoExt.diff :

+            }

             req.load(context, id, url);
         },

The patch simply adds the following around line 1887 to node_modules/requirejs/bin/r.js:

if (config.disableAutoExt && url.match(/\..*\.js$/)) {
    url = url.replace(/\.js$/, '');
}

UPDATE: Improved patch by moving url change deeper in the code so it no longer causes a hang after calling undef on a module. Needed undef because:

To disable caching of modules when developing with node.js add this to your main app file:

requirejs.onResourceLoad = function(context, map)
{
    requirejs.undef(map.name);
};
