如何在 Node/Express 中设置 404 路由

Question

How do I set up a 404 route in Node/Express? If the URL is not valid, I want to render an HTML or Handlebars file to the client

Answer 1

lets say you have an express app like this:

const app = express()

then put all your routes and at the end of all your routes put 404 route like:

 app.use((req, res) => { res.status(404).json({ success: false, message: "Page not found", }); });

if you are using handlbars or any other template engine, you can do it like:

 app.use((req, res) => { res.render('404.html') });
