Deploy Express.js app to Vercel

After research how to deploy Express.js app to Vercel. Finally, I found and got have an application has deployed to Vercel. It's take a lot of time from me but I am happy and hope this article will help something to you.

I. First of all, creating new Github repository and init new project nodejs.

II. Creating new project in Vercel

III. Installing package express to nodejs app.

IV. Creating and endpoint file index.js in root source.

V. Creating APIs in ./api folder or you can rename anything which you like.

• Here is an example for manage product from ./api/product.

VI. Testing before commit source to Github.

• After testing is 👌. Commit them to git to see something awesome.

VII. Ready to serve in Vercel.

VIII. Something went wrong in Vercel.

• Because Vercel just supports API from Framework JS as NEXT.JS, Nuxt.JS,... So if we develop a standalone application we need to configure or tell the server of Vercel how is it work by vercel.json file.

IX. Add new vercel.json file to root source.

• Commit it to GitHub and make sure version is 2 - this is required from Vercel.

X. Done, enjoy your moment.

Thanks for reading.
And I hope something good to you.
Here is repository which use in this post.

XI. Or you can follow this tutorial in youtube.

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

[Ha Tuan Em]

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.

Could you show us how to do this with Angular Universal or NestJS?

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"
        }
    ]

have you got any answer?

[Sami Kalammallah]

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

[Ha Tuan Em]

Waiting for my new post 😀

[Barhoumimohamedali]

thanks , this is really useful!

[sid-talesara]

Thanks man. I was stuck in last step and this helped me a lot.

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

[khaleel gibran]

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

[Ha Tuan Em]

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 =)
