// router.js router.use(express.static(path.join(__dirname, '../client/'))); router.get('/', (req, res)=> { res.sendFile(path.join(__dirname, '../client/index.html')); }); // server.js app.use('/', router); Gulp collects all the files and sends them to the build folder (checked, really all the files are there), and with all this, not all files are pulled into the browser.
PS: On the files I need, the node gives 304 status.
