cpf_cnpj

CPF/CNPJ

This package does some CPF/CNPJ magic. It allows you to create, validate and format CPF/CNPJ.

Installation

Using bower:

$ bower install cpf_cnpj --save

Using NPM:

$ npm install cpf_cnpj --save

Usage

// Node.js-specific
var CPF = require("cpf_cnpj").CPF;
var CNPJ = require("cpf_cnpj").CNPJ;

CPF.isValid("532.820.857-96");
//=> true

CPF.strip("532.820.857-96");
//=> 53282085796

CPF.format("53282085796");
//=> 532.820.857-96

CPF.generate(true); // generate formatted number
//=> 838.684.734-40

CPF.generate(); // generate unformatted number
//=> 72777632898

//==========================================================

CNPJ.isValid("41.381.074/6738-65");
//=> true

CNPJ.strip("41.381.074/6738-65");
//=> 41381074673865

CNPJ.format("41381074673865");
//=> 41.381.074/6738-65

CNPJ.generate(true); // generate formatted number
//=> 54.385.406/3140-07

CNPJ.generate(); // generate unformatted number
//=> 07033324230766

Strict Validation

By default, validations will strip any characters you provide. This means that the following is valid, because only numbers will be considered:

CNPJ.isValid("41#381#074-----6738\n\n65");
//=> true

CNPJ.strip("41#381#074-----6738\n\n65");
//=> 41381074673865

If you want to strict validate strings, use the following signature:

CPF.isValid(number, strict);
CNPJ.isValid(number, strict);

The same example would now return false:

CNPJ.isValid("41#381#074-----6738\n\n65", true);
//=> false
