this is awesome.. but when i try to build using express generator, it doesn't work, is there any help :(

Vercel is not supporting the Express Generator at the moment. Becasue it's attach to the pattern of serverless. Instead, you can use express traditional. Thanks.

But how can I deploy a express - handlebars to vercel ? Here is my folder structure and vercel.json :

"builds": [
        {
            "src": "src/*.js",
            "use": "@vercel/node"
        }
    ],
    "routes": [
        {
            "src": "/(.*)",
            "dest": "./src/routes/index.js"
        }
    ]

How about a full stack app where I use express on folder /server and react on /client ?

Your app doesn't work express-vercel-theta.vercel.app
Cannot GET /

This is really great, but isn't that the whole point of serverless functions?

Ha Tuan Em • Jul 5 '21

Actually, Express is a traditional server. It's not supported by serverless. But you still want to covert Express to serverless app. You can find out in this article. But I recommend you should using Next.js to making an awesome application with full serverless function.
Thanks =)

this is awsome ,hey can i use mongodb data base for this as well

Maria Campbell • Nov 29 '22

I'm working on a next.js app which uses mongod and host my backend on MongoDB Atlas. Yes, you can use MongoDB. And better yet would be to use Mongoose because of its schemas.
