Question 179625 in Javascript Question posted in
A very good W3school tutorial can be found here.

How can I read the build ID of NextJS in Javascript?

With NextJS, it’s possible to create a build ID, according to the docs : https://nextjs.org/docs/app/api-reference/next-config-js/generateBuildId

It’s also possible to get it according to the last git version : https://www.npmjs.com/package/next-build-id

But the question is : how do I read this build ID? I’d like to display it inside the window console.

    I have not tested it, but I think you can try the old (I guess it’s deprecated now, but it still should work) way of passing env vars through the env key in the config, like that:

    const nextBuildId = require('next-build-id')

const buildId = nextBuildId({ dir: __dirname })

const nextConfig = {
  generateBuildId: () => buildId 
  env: {
    BUILD_ID_ENV: buildId
  },
};

    And it will be available later as process.env.BUILD_ID_ENV

    To use it in the client side component potentially you would have to name it as NEXT_PUBLIC_BUILD_ID_ENV, not sure about it.

    this works in server component because that package uses fs

    import buildId from "next-build-id";

console.log("next-build-id", await buildId());

    proof of work:
