Data Validators

Installation

> npm install --save data-validators 

Using the Validator Service

We have a validation service that helps to manage and execute the wide range of validators that we have. You can get the service by requiring it from our module...

const { Validator } = require('data-validators');

With the Validator service we can check() the value below to make sure that it meets our range validator. Since the value 123 is outside of the 0 - 100 range, our validator will throw an error.

let errors = Validator.check(123, 'range', {
    min: 0,
    max: 100,
    message: 'Value must be in-between {min} and {max}'
});
 
console.log(errors); // outputs: ['Value must be in-between 0 and 100']

Executing a Validator Directly

You can also get and execute a single validator from our module...

const { Range } = require('data-validators');
 
let range = new Range({
    min: 0,
    max: 100,
    message: 'Range must be in-between {min} and {max}'
});
 
let errors = range.validate(250); // outputs: ['Range must be in-between 0 and 100']
