valid-ts v0.1.2
Valid-ts
It's a very simple validation library. No dependencies. Written in TypeScript. Useful for counstructing well-typed validation functions using a declarative interface. The validation functions are generally supposed to accept any input, ensure its shape during runtime and return typed values.
Installation:
npm install --save valid-ts
Documentation
I want to try out an unusual approach to documentation. I've created a sandbox project in the awesome codesandbox.io:
https://codesandbox.io/s/valid-ts-sandbox-9xxjj
All you need to know to use the library lives in the comments of src/index.ts there.
Example projects
There are two simple example projects to look at. Please check their README.mds to build and test them:
Server-side validation. This project shows an example of creating a union type "command" validator and using it in an Express endpoint. In README you can find some more use case examples.
Client-side validation. This project shows a very simple ValidTs-Formik integration - translating ValidTs errors to a form digestable by Formik.
Development
npm install
npm test
