This package does some

[CPF](http://en.wikipedia.org/wiki/Cadastro_de_Pessoas_F%C3%ADsicas) magic. It

allows you to create, validate and format CPF documents.

**HINT:** Check out the CNPJ counter part available at

.

## Installation

This lib is available as a NPM package. To install it, use the following

command:

```

npm install @fnando/cpf --save

```

If you're using Yarn (and you should):

```

yarn add @fnando/cpf

```

## Usage

```js

// Node.js-specific

const cpf = require("@fnando/cpf/commonjs");

// @import

import * as cpf from "@fnando/cpf"; // import the whole library

import { isValid as isValidCpf } from "@fnando/cpf"; // import just one function

// import via ; the lib will available as window.CPF

// <script src="cpf.js">

cpf.isValid("532.820.857-96");

//=> true

cpf.isValid("53282085796");

//=> 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

```

On the web, without transformation, just use `web/cpf.min.js`.

### Strict Validation

By default, validations will strip any characters you provide. This means that

the following is valid, because only numbers will be considered:

```js

cpf.isValid("101#688!!!!!!542......36");

//=> true

cpf.strip("101#688!!!!!!542......36");

//=> 10168854236

```

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

```js

cpf.isValid(number, strict);

```

The same example would now return `false`:

```js

cpf.isValid("101#688!!!!!!542......36", true);

//=> false

```
