const path = require('path')
const Dotenv = require('dotenv-webpack')

const nextConfig = {
  webpack: config => ({ ...config, node: { fs: "empty" } })
};
module.exports = phase => {
  if (phase === DEVELOPMENT_SERVER || phase === PRODUCTION_BUILD) {
    const withCSS = require("@zeit/next-css");
    return withCSS(nextConfig);
  }
  return nextConfig;
};
*module.exports =  {
  webpack: (config) => {
    config.plugins = config.plugins || []
    config.plugins = [
      ...config.plugins,
      // Read the .env file
      new Dotenv({

  case "stage":
    prefix = "https://state.domain.com/providers";
    break;
  case "production":
    prefix = "https://production.domain.com/providers";
    break;
  default:
    prefix = "";
    break;

Here my next.config.js configuration. But when I am trying to run then getting the message like Error! Network error: Unexpected token N in JSON at position 0

But when I am trying to run whatever into the bold(*) and kept only that thing into the next.config.js then working fine. How to configure multiple plugin into the module.export

Answer 1

Here is a simple way to use multiple nested plugins in Next.js

const withImages = require('next-images');
const withCSS = require('@zeit/next-css');

module.exports = withCSS(withImages({
    webpack(config, options) {
      return config
    }
  }))

If you want to using single one plugin then do this:

const withImages = require('next-images');

module.export = withImages();
