How to deploy an Express API to Vercel

#webdev #javascript #programming #beginners

Add vercel.json configuration After exporting Express, we have to tell Vercel what files to build, how to build them, and how to route them using a vercel.json file. So create a vercel.json file.

touch vercel.json

Then using Vercel Platform version 2, specify your index.js file and the NPM module Vercel will use to turn it into a serverless function...

{
  "version": 2,
  "builds": [
    {
      "src": "dist/server.js",
      "use": "@vercel/node"
    }
  ],
  "routes": [
    {
      "src": "/(.*)",
      "dest": "dist/server.js"
    }
  ]
}
