Description: Node Validation ensures that the data for a node meets specific criteria before being processed. In the context of data management and APIs, a node represents an entity within a data structure, and validation is crucial for maintaining the integrity and consistency of information. This process involves checking that incoming data is not only of the correct type but also satisfies certain logical or business conditions. For example, it may be required that an email field has a valid format or that a date field is not earlier than the current date. Node validation can be implemented through schemas, where types and constraints that data must meet are defined. This not only helps prevent errors in data manipulation but also enhances the developer experience by providing clear and specific error messages when data does not meet established requirements. In summary, node validation is an essential component in building robust and reliable applications, ensuring that data is accurate and useful from the moment it is entered into the system.
