configuration-validator

Validate environment variables by defining required keys and types, then running validation checks at startup to catch missing or misformatted settings before runtime errors occur in production environments.

Configuration validation supports .env files, JSON (config.js, appsettings.json), YAML (application.yml), and Python settings files, detecting and validating across multiple formats in a single workflow.

Yes, the validator implements security practices to detect and prevent accidental secret exposure in configuration files and environment variable definitions during validation.

Configure validation rules using schema enforcement with Joi, then apply environment-specific loading across Node.js, Python, and YAML or JSON configuration sources in development and CI workflows.

Yes, the validator generates .env.example templates and configuration documentation to speed up developer onboarding and clarify required settings.

Configuration validation runs across development, deployment, and CI workflows to identify missing variables and prevent incomplete configurations from reaching production.
