Deploy Express.js app to Vercel

#javascript #vercel #express #node

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 :(

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"
        }
    ]
