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. We invite you to explore our website and experience our comprehensive demo at no cost. This opportunity will allow you to assess the full capabilities of SurveyJS firsthand.
