SurveyJS is a set of four open-source JavaScript libraries that offer the benefits of a tailor-made in-house survey application, while considerably reducing the time and resources needed to deploy the system. These libraries are independent of specific server code or database requirements and seamlessly integrate with popular JavaScript frameworks, including React, Angular, Vue.js, jQuery, Knockout, and more. They are designed to communicate with any server that can handle JSON requests, ensuring compatibility with various server architectures and databases. The product family is composed of: - An open-source MIT-licensed rendering library that renders dynamic JSON-based forms in your web application, and collects responses. - A self-hosted drag & drop form builder that features an integrated CSS-based theme editor and a GUI for conditional rules. It automatically generates JSON definitions (schemas) of your forms in real time. - PDF Generator, a library that renders SurveyJS surveys and forms as PDF files in a browser; - The Dashboard library that allows you to simplify survey data analysis with interactive and customizable charts and tables.
