const { override } = require('customize-cra');
const webpack = require('webpack');

module.exports = override((config) => {
  config.resolve.fallback = {
    ...config.resolve.fallback,
    'process': false, // Set 'process' to false instead of using a mock
    'zlib': require.resolve('browserify-zlib'),
    'querystring': require.resolve('querystring-es3'),
    'stream': require.resolve('stream-browserify'),
    'path': require.resolve('path-browserify'),
    'fs': false,
    'timers': require.resolve('timers-browserify'),
    'crypto': require.resolve('crypto-browserify'),
    'http': require.resolve('stream-http'),
    'https': require.resolve('https-browserify'),
    'net': require.resolve('net-browserify'),
    'url': require.resolve('url/'),
    'assert': require.resolve('assert/'),
    'vm': require.resolve('vm-browserify'),
    'async_hooks': false,
    'child_process': false,
  };

  // Exclude the 'destroy' package
  config.module.rules.push({
    test: //node_modules/destroy//,
    use: 'null-loader',
  });

  // Resolve conflicting values for 'process.env'
  config.plugins.push(
    new webpack.EnvironmentPlugin({
      NODE_ENV: process.env.NODE_ENV === 'debug',
    })
  );

  return config;
});
