Formcookie

Formcookie is a JavaScript library designed to simplify the process of managing form data and cookies in web applications. It allows developers to easily capture values from form elements, store them in cookies, and then retrieve and pre-fill those forms using the stored cookie data. This can be useful for features like remembering user input across sessions, saving partially completed forms, or maintaining user preferences.

The library typically works by attaching event listeners to form submission and input change events. When a form is submitted, Formcookie can serialize the form's data into a string or JSON object. This data can then be saved as a cookie with a specified name and expiration time. When a user revisits a page with a form, Formcookie can check for the existence of a relevant cookie. If found, it can parse the cookie data and populate the corresponding form fields, providing a seamless user experience.

Formcookie aims to reduce the amount of boilerplate code required for such functionality. It often provides simple API calls for actions like saving form data to a cookie and loading form data from a cookie. This makes it a convenient tool for developers looking to quickly implement features that involve persistent form data storage. However, it's important to note that cookies have limitations regarding size and security, and Formcookie's use should be considered within these constraints.
