@feathersjs/schema provides a way to define data models and to dynamically resolve them. It comes in in the following main parts:

• JSON schema using TypeBox or plain JSON schema to define a data model with TypeScript types and validations. This allows us to:
  • Automatically get TypeScript types from schema definitions
  • Automatically generate API documentation
  • Create database adapter models without duplicating the data format
• Validators take a TypeBox or JSON schema to validate data to
  • Ensure data is valid and always in the right format
  • Validate query string queries and convert them to the right type
• Resolvers - Resolve properties based on a context (usually the hook context). This can be used for many different things like:
  • Adding default and computed values
  • Populating associations
  • Securing queries and e.g. limiting requests to a user
  • Removing protected properties for external requests
  • Ability to add read- and write permissions on the property level
  • Hashing passwords and validating dynamic password policies
