    Superstruct

    A simple and composable way to validate data in JavaScript

    This project is a lightweight validation library for JavaScript and TypeScript that helps you define data “shapes” and validate runtime values against them.

Its API is intentionally familiar if you’ve used TypeScript, Flow, Go structs, or GraphQL schemas, but the output is oriented around runtime...
