.env.local.production

You need to run a production build on your local machine:

// Order of precedence (lowest to highest priority) const files = [ .env , .env.$nodeEnv , .env.local , .env.$nodeEnv.local , .env.local.$nodeEnv // Support for the inverted pattern ]; .env.local.production

Enter .env.local.production :

"scripts": "build:prod-local": "NODE_ENV=production node env-loader.js && npm run build" You need to run a production build on

Therefore, if your NODE_ENV was set to production , the framework would look for .env.production.local . .env.local.production
