Validate

Validation

The validate command is used to verify the integrity and completeness of your environment variables. It checks if your .env.example is missing any keys from your actual .env file, if there are any extra keys and it also detects if there are duplicate variables defined in your files.

bash
envnix validate

What does it detect?

The validation process will flag three types of issues:

1. Missing Keys: Keys present in .env but not in .env.example.
2. Extra Keys: Keys present in .env.example but not in .env.
3. Duplicate Variables: Variables defined multiple times in the same file.

Why validate?

Validation is crucial for ensuring that all necessary environment variables are documented and distributed across your team. Running this command as part of your Git hooks or CI pipeline guarantees that your .env.example always reflects the requirements of your application.
