SurveyJS
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.

Choreographer-js
This library offers a simple yet powerful way to handle complex animations with ease. It allows for the addition of custom functions for animations that do not depend on CSS, making it quite versatile! To get started, just install it, include it in your package.json, and utilize it within your JavaScript code. You can quickly create scroll-based animations, activate effects based on the scroll position, and produce various animations corresponding to the mouse's X coordinate. By creating an instance of Choreographer, you gain the ability to initiate animations based on any variable you choose, like scroll position or mouse movement. For a better understanding of how it operates, it's advisable to check out the provided examples to see the library in action. However, take note that overlapping ranges for animations targeting the same style properties may result in unintended glitches! The library features two primary animation functions called 'scale' and 'change.' The progress concept allows for gradual value adjustments, enabling smooth transitions for elements like opacity or 2D movements. When the value is between 0 and 1, it indicates that you are within a specified range, giving you enhanced control over your animations. Ultimately, this tool can significantly elevate the quality and impact of your web animations, making them more engaging for users. With its intuitive approach, you can explore endless creative possibilities in your animation projects.
