includeFiles in build vercel.json

[priyang12]

i want includeFiles in builds property in vercel.json. i am trying deploy a node function which uses the google API key but I need the serverless function to access keys.json. i saw on the docs that I can add files to output by includeFiles but it's not available In "builds" and if I use it functions using it started looking for public dir. how to i point it to use the index.js which a node function?

For your case you shouldn't need includeFiles, since the bundler will automatically notice that you are using that file and bundle it into the Serverless Function implicitly. Be sure to use fs.readFileSync() or similar to trigger the bundling mechanism, something like:

import fs from 'fs';

const keys = JSON.parse(fs.readFileSync(__dirname + '/keys.json'));

export default (req, res) => { … }

To answer your original question though, includeFiles property belongs in the config object with the builds array. So something like:

{
  "builds": [
    {
      "src": "api/*.js",
      "use": "@vercel/node",
      "config": {
        "includeFiles": [ "keys.json" ]
      }
    }
  ]
}

Note that you can also achieve similar with the "functions" config within vercel.json, which is the preferred syntax over the legacy builds property.

Hope that helps. Cheers!
