add-route-constraint

What problem does it solve?

This Skill automates the creation and registration of custom route constraints in ASP.NET Core, ensuring that specific URL path parameters meet defined validation criteria directly at the routing layer, preventing invalid requests from reaching controllers.

Core Features & Use Cases

• Custom Validation: Define regex patterns to validate string path parameters.
• Automatic 404 Responses: Invalid routes automatically return a 404 status code.
• Use Case: Ensure that an id parameter in a URL like /api/users/{id} only contains alphanumeric characters and periods, up to 100 characters long.

Quick Start

Add a route constraint named 'myConstraint' that validates string parameters using a regex pattern.
