Alright, let's get started by setting up a new project in Xano. Head over to the Xano dashboard and hit that "Create Project" button. Give your project a name and tweak the initial settings as needed. Easy peasy!

Once your project is good to go, navigate to the "Environment" tab in the project settings. Click on "Environment Variables". Here, you can define different variables that will be used to manage configurations for different environments like development, testing, and production.

In the Environment Variables section, click on “Create Variable”. Define variables such as DB_CONNECTION_STRING, API_KEY, DEBUG_MODE, etc. Provide appropriate values for these variables depending on the environment.

Within the "Environment" tab, set up different environments like Development, Testing, and Production. Assign specific variables to these environments. Ensure that each environment has its own set of unique values for the defined variables.

As you create API endpoints or workflows, replace hard-coded values with the environment variables. This ensures that when you switch environments, the configuration will automatically update according to the specified environment variables.

Use the Environment dropdown in the top-right corner of the Xano dashboard to switch between environments. Ensure that your project behaves as expected in different environments by running tests. Confirm that environment-specific configurations are correctly applied during these tests.

Ensure sensitive data included in your environment variables, such as API keys and database credentials, is properly secured. Avoid exposing these variables in logs or client-side code.

Document all your environment variables and configurations. Make sure anyone who works with the project understands what each environment variable does and how to set them up for different environments.
