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.

Windows Presentation Foundation (WPF)
Windows Presentation Foundation (WPF) is a framework exclusive to Windows in the .NET ecosystem, utilizing a vector-based rendering engine that is independent of resolution, thereby harnessing contemporary graphics hardware to create visually engaging desktop applications. This framework boasts a rich feature set, including XAML markup, an extensive array of controls, data binding capabilities, layout management, 2D and 3D graphics, animation, styling, templating, document handling, as well as multimedia integration, text, and typography functionalities; it also permits the usage of other .NET APIs. WPF is structured as a collection of .NET types located within the System.Windows namespace and accommodates traditional programming methodologies, such as class instantiation, property modification, method invocation, and event handling, along with advanced concepts including dependency properties and routed events. With WPF, developers have the ability to craft user interfaces declaratively through XAML while executing logic in the code-behind, which not only streamlines the division between user interface and business logic but also enhances globalization efforts and fosters collaboration between designers and developers, making it a versatile choice for modern application development. This dual approach in WPF ensures that both aesthetic and functional aspects of applications can evolve in harmony, ultimately resulting in a more cohesive user experience.
