If you use express, then app.use(express.static(path.join(__dirname, 'public'))); set the static file path, so that you can directly access the static html in the public directory. If there is a test.html in your public directory, in the routing Just add res.redirect('/test.html') to the jump logic, public is equivalent to the root path.
