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.

Svelte
Svelte represents a groundbreaking method for creating user interfaces. Unlike conventional frameworks such as React and Vue, which primarily operate in the browser, Svelte delegates much of its processing to a compilation phase that occurs during the app's build process. Rather than employing strategies like virtual DOM diffing, Svelte generates optimized code that precisely modifies the DOM in response to changes in your application's state. Recently, Svelte has been celebrated as the most loved web framework, garnering the highest levels of satisfaction among developers in recent industry surveys, and we believe you will appreciate it as well. If you wish to dive deeper, check out the introductory blog post for further insights. Svelte is designed for crafting rapid web applications, aligning with other JavaScript frameworks like React and Vue in their goal to simplify the creation of engaging interactive user interfaces. However, the key distinction lies in Svelte's ability to transform your application into optimal JavaScript during the build phase, rather than processing your code at runtime, which can enhance overall performance. This innovative approach not only streamlines development but also results in faster loading times for users.
