Suretype is a JSON validator targeting TypeScript and JSON Schema. It is ridiculously type-safe when used in TypeScript, which is good for accuracy, but also for aiding IDE auto-complete. It's as easy as Joi, but ~70x faster. It's (at least) as typesafe as Superstruct, but ~100x faster. ~2500x faster than Zod and ~1600x faster than ow. It supports most (if not all) of JSON schema, and nothing beyond that, so that the validator schemas written in TypeScript (or JavaScript) can be ensured to be convertible into JSON schema. This also prevents sure type from becoming feature-bloated, it has a small and extremely simple API.
Features
- Compile a validator function (using the very fast Ajv)
- Extract the corresponding JSON Schema
- Deduce a TypeScript type corresponding to the validator schema (at compile-time!)
- Examples available
- Type-guarded validator
- Type-ensured validator
- Validate or ensure without compiling
