Validate-data NPM

Validate Data

NodeJs backend library for validate data against the rules provided.

Usage

Install the library with npm install validate-data

const validate = require('validate-data');

// Validation rules 
const rules = {
        required: "email name age",
        email: "email",
        string: "email name",
        number: "age",
        array: "options",
        boolean: "status"
    };

// Data to be validated
const data = {
    email: "example@sample.com",
    name: "John",
    age: 25,
    options: [1,2,3],
    status: true
};

// Using the package
let error = validate(data, rules);

console.log(error);

Error will be null if all the validation rules passs, otherwise will get the following error

[
    {
        rule: 'required', // Failed rule
        errorOn: ['sample'] // Failed data fields
    },
    {
        rule: 'email',
        errorOn: ['email']
    },
    {
        rule: 'number',
        errorOn: ['age']
    },
    {
        rule: 'array',
        errorOn: ['options']
    },
    {
        rule: 'boolean',
        errorOn: ['status']
