Verify CPF

Verify CPF is a TypeScript library designed to validate Brazilian CPFs. It ensures that the CPF is correctly formatted, checks for repeated digits (e.g., 111.111.111-11), validates the number of digits, and confirms whether the CPF is valid or not.

📦 Installation

To install the library, use the following command:

npm install h7-validate-cpf

🚀 Usage

Here's how to use the VerifyCPF class to validate a CPF:

import { VerifyCPF } from "h7-validate-cpf";

const verifyCPF = new VerifyCPF();

console.log(verifyCPF.verifyCPF("12345678909"));
console.log(verifyCPF.verifyCPF("11111111111"));

📖 Features

  • Validates CPFs: Checks if the provided CPF is correct.
  • Rejects repeated digits: Detects invalid CPFs with all digits the same (e.g., 111.111.111-11).
  • TypeScript support: Fully typed and compatible with TypeScript projects.
  • Lightweight: A simple and efficient library with no dependencies.

🛠️ How it Works

This library verifies CPFs by:

  • Removing all non-numeric characters.
  • Calculating the two verification digits based on the CPF algorithm.
  • Comparing the calculated verification digits with the input to determine validity.

📜 Example Use Case

Imagine an application where users must provide a valid CPF for authentication or registration. Using this library, you can ensure that only valid CPFs are accepted:

import { VerifyCPF } from "h7-validate-cpf";

const cpf = "12345678909";
const verifyCPF = new VerifyCPF();

if (verifyCPF.verifyCPF(cpf)) {
  console.log("O CPF é válido.");
} else {
  console.log("CPF inválido. Por favor, verifique e tente novamente.");
}
