React-app-rewired: How to pass argument to config-override?

[huygn]

Hi, I want to pass argument to rewire for webpack-bundle-analyzer, is it possible?

react-app-rewired build --bundle-report

if (env === "production") { // && arg === "--bundle-report"?
   config.plugins.push(new BundleAnalyzerPlugin());
}

In the override:

const bundleReportIndex = process.argv.indexOf('--bundle-report');
if (env === 'production' && bundleReportIndex !== -1) {
  config.plugins.push(new BundleAnalyzerPlugin());
}

Then when you actually do the command line: npm run build --bundle-report or yarn build --bundle-report.

If you want a script target in package.json:

"scripts": {
  "build": "react-app-rewired build",
  "build:bundle": "react-app-rewired build --bundle-report"
}

and then run it with npm run build:bundle or yarn build:bundle.

Thanks! 👍

I would use just environment variables set directly in cli or with help of .env* files, if I were you. Then you just check it with process.env.MY_VAR
