vlid.js

Lightweight validation library with NO dependencies targeting web browsers and Node.js. A nice Joi alternative with a similar API.

A full featured validation library at just 8kb minified (before gzipping).

NOTE: vlid.js targets language features supported in 90%+ browsers. This means that it does use some more widely-supported ES6 features, and thus requires a modern-ish browser and/or Node 8+. Most notably, IE11 is not supported. All versions of Firefox, Safari, Chrome, and Edge released within the past several years are fully supported.

Size

Bundle size is very important, and a lot of attention is paid to keeping the code lean and small. We try to strike a balance of providing all the core validations and logic that you most commonly need, while making it easy to provide your own custom validation rules for anything else.

Installation

Install from NPM or Yarn:

npm install vlid --save

yarn add vlid

Use in your JavaScript:

const v = require('vlid');`

Or with import:

import v from 'vlid';

Usage

v.any()

The base validation object, can be used to represent any value or as a base for completely custom new validation rules.

let result = v.validateSync(v.any(), 'whatever you want'); // result.isValid = true

Full API docs coming soon. Still working on what the full public API will be.
