React Credentials
What is Archetype?
Cast a given obj’s properties to the correct types
So It’s Joi, JSONSchema, PropTypes, Flow?
● Easy custom types & nested (vs Joi, JSONSchema)
● Casting + validation in middleware vs PropTypes
● Runtime, not compile time vs Flow (buggy APIs)
Core Principles
● Composable: can nest and transform types
● Inspectable: introspect deeply nested paths
● Extendable: any class is a valid custom type

Know Your Assumptions are Correct
And No More Walls of If Statements
