How do I use environment variables in Angular?

In Angular, you can use environment variables by defining them in the src/environments folder. You typically have environment.ts for development and environment.prod.ts for production.

Can I access these variables in my components?

Yes, you can access them by importing the environment file. For example, you can use import { environment } from '../environments/environment'; and then access the variables like environment.apiUrl.

What if I want to add a new variable?

You can simply add a new property to the environment files. For instance, add apiKey: 'your-api-key' in both environment.ts and environment.prod.ts.

Are there any best practices for using environment variables?

Yes, keep sensitive information out of your source code, use different files for different environments, and avoid hardcoding values.
