Node Clearing Webkit Cache
I recently discovered that it c:/Users/username/AppData/Local/AppName/Cache
contains over 100k cache files.
I read a bit and saw that the method gui.App.clearCache()
should fix this. I run this method on startup and on shutdown of the application. (after gui assignment require("nw.gui")
)
However, this doesn't seem to help. Nothing is removed.
Any ideas why this is so?

The request cache is apparently only available on global.require.cache
.
Clearing this 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 for me, nor for gui.APP.clearCache()
, nor for gui.Window.get().reloadIgnoringCache()
was.

Go to the same problem, so I created a quick solution to fix 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 works with 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
});
});
};

It's 2019 now and clearCache () works 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 regardless of your platform. I tested it on Mac OS, but maybe there may be user rights issues on Linux.
On macOS, you can check in real time that the cache folder is cleared in
