 Environment variables work like key-value pairs to help manage configurable settings across different deployment environments, including development, staging, and production. Unlike secrets, which store sensitive data, environment variables are typically nonconfidential and are used for controlling application behavior in different environments. Another key difference is that environment variables are stored and managed by the Amplify managed service. You can set environment variables in the Amplify console (view the [AWS Amplify Hosting User Guide](https://docs.aws.amazon.com/amplify/latest/userguide/environment-variables.html#setting-env-vars) for detailed instructions).

 With the implementation above, the environment variable is written in a `.env` file. However, you can write it to any file depending on your platform.
