FAQ

Questions JSON Schema Strict Validator owners ask.

  • 01

    What does 'strict mode' mean in this validator?

    Strict mode means that if a schema does not explicitly define additionalProperties, the validator treats it as false. Any property found in the JSON instance that is not declared in the schema will trigger an error.

  • 02

    Can I use this to check for breaking changes in my API?

    Yes, by using the evaluate_compatibility capability, you can compare an old schema against a new one to identify removed required fields or properties that might break your integration.

  • 03

    How do I validate environment variables?

    You can use the verify_integrity capability. Pass a string of key-value pairs (like PORT=8080) and an array of constraints to ensure each key matches its expected type.
