In MongoDB Compass 1.18, the user experience of creating validation rules has been dramatically refreshed, introducing a context-sensitive, field-aware editor that allows for more interactive and responsive validation creation environment. This new editor provides rapid feedback and autocompletion features, such as support for $jsonSchema validation, which enables users to define standard rules for good quality documents using JSON Schema. With the removal of the rules builder, the editor offers a more user-friendly experience, allowing users to easily create complex validation rules with minimal effort. The new Validation view in Compass 1.18 provides features such as error notifications and autocompletion options, making it easier for users to validate their data and ensure data quality.
