Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Readme

The @type-ddd/cpf library provides TypeScript type definitions for handling CPF (Cadastro de Pessoa Física) in Domain-Driven Design contexts. It facilitates the validation and manipulation of CPF numbers, ensuring they adhere to the Brazilian legal standards.


Installation

Install rich-domain and @type-ddd/cpf with your favorite package manager


npm i rich-domain @type-ddd/cpf

# OR

yarn add rich-domain @type-ddd/cpf

Usage

Don't worry about removing special characters; they are automatically stripped from all instances.


import { CPF } from '@type-ddd/cpf'

// Instance of cpf or throws an error if provide an invalid value
const cpf = CPF.init('54097792000193');

// OR

// Result of cpf (Check Result pattern docs)
const result = CPF.create('54097792000193');

result.isOk(); // true

// cpf instance or null if provide an invalid value
const cpf = result.value();

Compare values or instances

Method to compare two instances or values.


// value as string 
const isEqual = cpf.compare('54097792000194')

// Output: false

// OR

// value as instance of cpf
const isEqual = cpf.compare(cpf2)

// Output: false

Check string is valid cpf

Don't worry about removing special characters; they are automatically stripped from all instances.


const result = CPF.isValid('54097792000193');

// Output: true

Special chars

If you need the value with the mask, you can use the toPattern method:


cpf.toPattern();

// Output: 54.097.792/0001-93

Or if you need to apply mask from a string value you may use addMask method


CPF.addMask('54097792000193');

// Output: 54.097.792/0001-93
