I have an Angular 19 application deployed, which utilizes the environment.ts and environment.production.ts files to manage secrets and URLs. To handle these securely, I created the necessary environment variables within my Vercel project settings. However, when attempting to load the application, I encounter an error indicating that the specified environment variable could not be found.
Uncaught ReferenceError: process is not defined at environment.ts at urlBackend: process.env.NG_APP_API_URL
The error isn’t actually about the environment variable, but if you read closely you’ll see it says process is the thing that’s not defined.
process is a node global that will only exist serverside, so it’s possible you’re seeing this error because it’s trying to run this code in the browser instead of at build time
I don’t know Angular too well, but it appears to not have built in support for reading real environment variables and people seem to be using this lib to solve it
