import { NextResponse } from "next/server";
import { jwtVerify } from "jose";
import getConfig from "next/config";

const { publicRuntimeConfig } = getConfig();

export async function middleware(request) {
}


I am trying to import my config from next.confug.js file into my middleware.js file, but when I try to do so I get the next error

Cannot destructure property 'publicRuntimeConfig' of 'next_config__WEBPACK_IMPORTED_MODULE_2___default(...)(...)' as it is undefined.


I am using it in many other js file without problem, I guess is something related to edge run, same that happened to me when trying to use jsonwebtoken module. Any help is help, thanks

Or rather what exactly do you need it for?

@ncls. Hi again! What exactly do you need from the NextConfig?

Jwt secret to verify the tokens
I can hard code it but is not as good

It should be inside your .env file. You can get it from there using a library like [dotenv](https://npmjs.com/package/dotenv)

is not possible to use next.config.js file? as I already have all the important variables stored in there
/** @type {import('next').NextConfig} */
const nextConfig = {
    reactStrictMode: true,
    serverRuntimeConfig: {
        dbConfig: {
            host: 'localhost',
            port: 3306,
            user: 'root',
            password: '', // @@@
            database: 'clinic-db'
        },
        secret: 'test'
    },
    publicRuntimeConfig: {
        apiUrl: process.env.NODE_ENV === 'development'
            ? 'http://localhost:3000/api' // development api
            : 'http://localhost:3000/api' // production api
    }
}

module.exports = nextConfig

I think you actualy don't need the dotenv library. Next.js should have built-in support for enviroment variables
