I recently discovered that c:/Users/username/AppData/Local/AppName/Cache contained over 100K cache files.

I read up a bit and saw that the gui.App.cl

    Ran into the same issue so I created a quick solution to solve the problem temporarily until I can rely on the native gui.App.clearCache function. This removes the entire Cache directory and recreates it asynchronously.

    This requires fs-extra and should work on Linux, OSX and Windows.

    var customClearCache = function(){
      var dir = path.join(gui.App.dataPath, '/Cache');
      fs.remove(dir, function(err) {
        if (err) return console.error(err)
        fs.mkdirs(dir, function(err) {
          if (err) return console.error(err)
          // This is where I start my app
        });
      });
    };

    The require cache is apparently only available on global.require.cache.

    Clearing that cache manually made it work for me.

    for(module in global.require.cache){
        if(global.require.cache.hasOwnProperty(module)){
            delete global.require.cache[module];
        }
    }
    location.reload()
    

    Neither the gui.APP.clearCache() nor the gui.Window.get().reloadIgnoringCache() had any effect for me.

    It is now 2019 and clearCache() does function by adding the following:

    var gui = require('nw.gui'); 
    gui.App.clearCache();
    

    or

    nw.App.clearCache();
    

    This will clear the HTTP cache in memory and the one on disk whatever your platform. I have tested it on Mac OS but maybe there can be user permission issues on Linux.

    On MacOS, you can check in real time that the cache folder is emptied at ‎⁨
