toniw-validator

The minimalist data validation library you didn’t know you needed — until now. Say goodbye to endless if-checks and hello to clean, sweet validation magic.

Installation npm install validator

Quick Start import {validate, required, minLength, maxLength, number} from "toniw-validator" const rules = { name: [required(), minLength(3), maxLength(10)], age: [required(), number()], }; const data = { name: "John", age: 30 };

const result = validate(rules, data); console.log(result);

API Breakdown validate(rules, data) rules: object with fields as keys and arrays of validator functions as values

data: object with the actual stuff to check

Returns:

{ isValid: boolean, // true if all clear, false if drama errors: { // detailed receipts on what went wrong [field]: string[] } }

Why bother? Stop writing the same boring checks over and over

Get nice, readable error messages

Lightweight and zero dependencies — no extra fat here

Future Features (coming soon™) Async validators (because promises are the future)

TypeScript typings, so your editor stops crying

More built-in rules, because variety is life
