🛡️ Backend API Validation Middleware

This project provides a set of middleware functions for validating common user input fields in an Express.js application. The middleware functions include validation for name, email, phone number, birthday, and password.

✨ Features

• Name Validation: Ensures the name contains only letters and spaces.
• Email Validation: Ensures the email follows the RFC 5322 standard.
• Phone Validation: Ensures the phone number follows the format xxx-xxx-xxxx.
• Birthday Validation: Ensures the birthday follows the formats mm/dd/yyyy, mm-dd-yyyy, mm.dd.yyyy, or mm dd yyyy.
• Password Validation: Ensures the password is at least 8 characters long and contains at least one letter and one number.

📦 Installation

To install the package, use npm:

npm install @sjeremich23/pwa-utils

🚀 Usage

ES6 Module

Import the middleware functions in your Express.js application:

import {
  validateAll,
  validateName,
  validateEmail,
  validatePhone,
  validateBirthday,
  validatePassword,
} from "@sjeremich23/pwa-utils";
import express from "express";

const app = express();

app.use(express.json());

app.post("/signup", validateAll, (req, res) => {
  // Your signup logic here
  res.send("Signup successful!");
});

// Example of using individual validation functions
app.post("/validate", validateName, validateEmail, (req, res) => {
  // Your validation logic here
  res.send("Validation successful!");
});

app.listen(3000, () => {
  console.log("Server is running on port 3000");
});
