Welcome to NFSFU234FormValidation Library

Hello there! 👋 We're thrilled to introduce you to NFSFU234FormValidation — a lightweight JavaScript library that makes form validation a breeze, whether you're working with plain HTML forms or React.

Why you'll love it

• Customizable validation messages — tailor errors to your product's voice.
• Required field support — make sure the important stuff gets filled in.
• Inline error displays — messages appear right where the user needs them.
• Modal error notifications — for a more deliberate, focused error flow.

Getting started

Check out the Installation guide to get the library into your project, then head to Initialization to wire it up.

Basic example

const customErrorMessages = {
  text: "EMPTY FIELD",
  select: "SELECT FIELD IS REQUIRED",
  email: {
    empty: "EMPTY EMAIL",
    format: "The email is not in the right format"
  }
};

const myForm = document.getElementById("myForm");
nfsfu234FormValidation.validate(myForm, { customErrorMessages }, (response) => {
  const { message, type, data } = response;
  console.log(response);
});
