Introducing valid-correct: Elevate Your Form Validation with Error Handling and Correction

As developers, we know that form validation is a critical part of any application. Whether you're building a simple sign-up form or a complex data entry system, ensuring the accuracy and integrity of user input is essential. However, providing users with helpful feedback when something goes wrong can be just as important. That’s where valid-correct comes in—a new npm package designed to take your form validation to the next level.

Why valid-correct?

valid-correct isn’t just another validation library. It’s built with a unique focus on both error handling and user correction. Instead of just telling users what they did wrong, valid-correct offers actionable suggestions on how to correct their input, making it easier for them to get it right the first time.

Key Features

Comprehensive Validation Rules

valid-correct offers a wide range of validation methods, from simple checks like required, min, and max to more complex validations using regular expressions and custom functions.

Detailed Error Messages

Each validation rule not only checks for compliance but also provides clear and specific error messages. These messages help users understand exactly what went wrong.

Correction Suggestions

What sets valid-correct apart is its correction suggestion feature. When a validation error occurs, the package offers practical advice on how to fix the issue, guiding users toward valid input.

Easy Integration

Integrating valid-correct into your existing Node.js application is straightforward. With just a few lines of code, you can start using this powerful validation tool in your forms.

How to Get Started

Getting started with valid-correct is simple. First, install the package using npm:

npm install valid-correct

Next, define your validation schema. Here’s a quick example:

const Validator = require('valid-correct');

const schema = {
    username: value => Validator.string(value).required().min(3).max(30),
    email: value => Validator.string(value).email().required(),
    password: value => Validator.string(value).required().min(8).pattern(/^[a-zA-Z0-9]{8,}$/, 'Password must be at least 8 characters long and alphanumeric.')
};

const userInput = {
    username: 'jsmith',
    email: 'john.smith@example.com',
    password: 'pass123'
};

const validationResult = Validator.validate(userInput, schema);

if (validationResult.isValid) {
    console.log('Validation successful!');
} else {
    console.log('Validation errors:', validationResult.errors);
}

In the example above, we define a schema that validates a username, email, and password. If any of these fields fail the validation checks, valid-correct will return detailed error messages along with correction suggestions.

Example of Validation Errors

Let’s say a user submits the following input:

{
    "username": "js",
    "email": "john.smith@com",
    "password": "pass"
}

valid-correct might return the following validation errors:

{
    "username": [
        {
            "message": "Minimum length is 3 characters.",
            "correction": "Please enter at least 3 characters. Current length is 2."
        }
    ],
    "email": [
        {
            "message": "Invalid email format.",
            "correction": "Please enter a valid email address (e.g., user@example.com)."
        }
    ],
    "password": [
        {
            "message": "Password must be at least 8 characters long and alphanumeric.",
            "correction": "Please enter a valid password with at least 8 alphanumeric characters."
        }
    ]
}

As you can see, valid-correct provides clear instructions on what needs to be corrected, making it easier for users to submit valid data.
