auth-validify simplifies and strengthens data validation in your Node.js applications. It provides a comprehensive set of validation functions for common data types, along with options for customization to meet your specific needs.
This library empowers you to:
- Ensure the integrity and security of user-submitted data.
- Prevent invalid inputs from reaching your backend logic.
- Enhance user experience with clear and actionable error messages.
npm install auth-validifyUsage
Offer practical examples demonstrating how to use each validation function:
1. Basic Validation:
const { validator } = require('auth-validify');
const email = 'someone@email.com';
const password = 'StrongPassword123!';
if (validator.isEmail(email) && validator.isValidPassword(password)) {
console.log('Valid email and password!');
} else {
// Provide helpful error messages
if (!validator.isEmail(email)) {
console.error('Invalid email format.');
}
if (!validator.isValidPassword(password)) {
console.error('Password must be at least 8 characters long and contain a combination of letters, numbers, and special characters.');
}
} const { validator } = require('auth-validify');
// Set custom password length (minimum 12 characters)
const options = { minLength: 12 };
if (validator.isValidPassword(password, options)) {
console.log('Password meets custom criteria!');
} else {
// ... (error handling)
}- Comprehensive Validation: Covers common data types like email, password, phone number, username, and URL.
- Customizable Rules: Tailor validation criteria to your application's specific needs (e.g., minimum password length, allowed email domains).
- Clear Error Handling: Throw informative exceptions or provide custom error messages for better debugging and user experience.
- Asynchronous Support: Enables seamless integration with promises or async/await patterns.
- Well-Documented: Provides detailed documentation with clear examples and API descriptions.
