Runtime Type Checks for TypeScript (by fabiandev)

fabiandev.github.io

A minimal, blazing fast, TypeScript runtime type-checker. It is intuitive, API-centric, and customisable. A must-have for API payload sanitiser, type-checking, validation, error handing and messaging helper -- all in a small and neat pack. [Moved to: https://github.com/calvintwr/not] (by calvintwr)

There is also https://github.com/fabiandev/ts-runtime for Typescript that looks more polished. Too bad both these projects were abandoned, it would be such a cleaner alternative to libraries like io-ts.

I like io-ts though it has bad documentation. More random examples are ts-runtime and ajv. JS examples are joi, v8n, validate.js.

So I have been writing APIs for a long time, and I find managing type-checking and error messaging for API requests a chore. I consolidated what I wrote to handle all this into Node module:
