SurveyJS comprises a collection of four open-source JavaScript libraries that provide the advantages of a customized, in-house survey application while significantly minimizing the time and resources required for deployment. These libraries function independently of specific server code or database needs, allowing for seamless integration with well-known JavaScript frameworks such as React, Angular, Vue.js, jQuery, Knockout, and others. They are built to interact with any server capable of processing JSON requests, thereby ensuring compatibility with a wide range of server setups and databases.
This product suite includes:
- An open-source library licensed under MIT that facilitates the rendering of dynamic JSON-based forms within your web application and captures user responses.
- A self-hosted form builder featuring drag-and-drop functionality, an integrated CSS theme editor, and a graphical user interface for setting conditional rules; it also generates JSON definitions of your forms in real time.
- A PDF Generator library that allows for the conversion of SurveyJS surveys and forms into PDF files directly in the browser.
- The Dashboard library, which enhances survey data analysis through interactive and customizable charts and tables.

Moment.js
Moment.js is a robust JavaScript library designed for comprehensive date manipulation, including parsing, validating, formatting, and adjusting dates. It operates effortlessly across both web browsers and Node.js, ensuring consistent compatibility across various platforms, a capability that is validated through unit tests executed in both environments. Due to its extensive usage, Moment.js has found its way into millions of applications worldwide. By September 2020, it recorded a remarkable achievement of surpassing 12 million downloads weekly! Since its launch in 2011, Moment has undergone numerous improvements, yet its foundational design principles have largely remained unchanged. It supports Internet Explorer 8 and later versions, broadening its accessibility to a diverse audience. While some date libraries are modularized or use plugins, others take advantage of the ECMAScript Intl API to enhance locale and time zone features. Libraries such as Moment and Moment-Timezone still provide their own files dedicated to locale and time zone information. This flexibility is essential, particularly as various locales have different interpretations of week-of-the-year numbering; Moment.js therefore includes options for retrieving and setting the localized week of the year, ensuring a tailored user experience. Additionally, developers appreciate its wide array of functionalities, making Moment.js an indispensable resource for anyone working with dates and times in web development.

jQuery
jQuery is a nimble yet robust JavaScript library that presents an extensive array of functionalities. It streamlines operations like altering and navigating through HTML documents, managing events, crafting animations, and executing Ajax requests via a straightforward API that is designed to work seamlessly across a variety of web browsers. New users of jQuery will find that it enables the retrieval of a collection of matched elements, either by querying the DOM with specific parameters or by supplying an HTML string. Furthermore, it is crucial to be aware that some of the API's methods have been deprecated in recent jQuery releases, which can influence how developers engage with the DOM attributes of elements. Staying updated on these modifications is vital for maximizing the effectiveness of jQuery, as adapting to changes can enhance your coding efficiency and ensure better compatibility with future updates.
