Valdie

A TypeScript and JavaScript Validation Library that works

• 🎉 It doesn't have any dependancy
• 💪 Simple api
• 📦 It works with TypeScript

You probably never knew you needed it but here you go.

Getting started

npm i valdie

or

yarn add valdie

using deno

import valdie from 'https://cdn.skypack.dev/valdie'

Documentation

1. isEmail
2. isInteger
3. isString
4. isURL
5. isDistinct
6. isIPv4
7. isUuid

They are two ways of consuming our api

import { isEmail } from "valdie"

console.log(isEmail("[email protected]")) // true
let { message,success } = isEmail("[email protected]")

isInteger

console.log(isInteger(34)) // true

isDistinct

import { isDistinct } from "valdie"

console.log(isDistinct(["true", "false", "yes", "no"]));  // true
let { message,success } = isDistinct([1, 2, 3, 4, 5]);

isIPv4

Version 4 IP addresses (IPv4) validator

import { isIPv4 } from "valdie"

// sample
console.log( isIPv4('192.168.0.3') ) // { success : true }
console.log( isIPv4('rrtr3345') )  // { message : "rrtr3345 is not a valid IPv4" , success : false } 

// usage 
const myIp : string = "192.168.1.1"
const  { message , success } =  isIPv4(myIp)

if(success) 
    console.log("myIp is an IPv4 address")
else 
    console.log("It's not an IPv4 address")

isUuid

import { isUuid } from "valdie"

// sample

console.log(isUuid('34483ae5-8a6b-4965-9384-cd0ce0191e84')) // { success : true }
console.log( isUuid('helloworld') )  // { message : "helloworld is not a valid uuid" , success : false } 

// usage 

function generateRandomUuid() {
    return 'xxxxxxxx-xxxx-4xxx-yxxx-xxxxxxxxxxxx'.replace(/[xy]/g, function(c) {
        var r = Math.random() * 16 | 0,
            v = c === 'x' ? r : (r & 0x3 | 0x8); // 
        return v.toString(16);
    });
}
const  { message , success } =  isUuid(generateRandomUuid())

if(success) 
    console.log("this is a valid uuid")
else 
    console.log("It's not a valid uuid")

// or 
import valdie from "valdie"

const result = valdie('String to test').isString().isUuid();
