Strickland is not a bloated collection of validators. Instead, Strickland is an extensible framework on which you can build your application's validation. To achieve the extensibility goal, Strickland keeps its core concepts at a minimum and provides you with the power to extend the concepts as needed in your application.

Areas of Extensibility

We learned that Strickland is made up of three core concepts: Validators, Validation, and Validation Results. All three of these concepts are extensible.

• ​Validator Factories​

• ​Validation Context​

• ​Validation Result Props​

Extensibility Pattern

With validator factories, validation context, and validation result props, even the simplest validators can become extremely extensible. When combining these features, an extensibility pattern emerges.
