The Hype Reactive Content Library is a powerful tool that allows you to create reactive content with data binding and visibility control for your Hype projects. This library is designed to work seamlessly with Tumult Hype and provides an easy way to manage and update your project's content by using data attributes.
To start using the Hype Reactive Content Library, follow these steps:
- Include the library file in your Hype project.
- Set up custom data properties and data attributes in your project elements.
- Use the provided API functions to manage and update your content.
Q: How do I include the Hype Reactive Content Library in my project?
A: To include the library in your project, add the Hype Reactive Content script file to your project's resources, and include the script file in the head section of your exported HTML file.
Q: How do I set up custom data properties and data attributes for my elements?
A: You can set up custom data properties by adding them to the data-* attributes in your HTML elements. For example, use data-content to set the content of an element based on the custom data property, and data-visibility to control the visibility of an element.
Q: Can I use the Hype Reactive Content Library with other Hype extensions?
A: Yes, the Hype Reactive Content Library is designed to work seamlessly with other Hype extensions, such as Hype Action Events and Hype Data Magic.
Q: How do I update the content of my elements when a custom data property changes?
A: In general, the content automatically refreshes when you change a value. It uses a debounce approach and if you need to update immediately you can use hypeDocument.refreshReactiveContent function, which updates the content and visibility of your elements based on the custom data properties.
Q: How do I use the data-effect attribute in my elements?
A: To use the data-effect attribute, simply add it to your HTML elements and assign it a value that is a valid JavaScript code. This code will be run dynamically and can interact with the custom data properties.
Q: What kind of effects can I create with the data-effect attribute?
A: The data-effect attribute allows dynamic JavaScript code execution, which means you can create a wide range of effects such as changing color, size, position or any other property based on some data change.
Q: How do I update the effect of my elements when a custom data property changes?
A: The data-effect attribute is reactive, so any changes in the custom data property will automatically trigger the code in the data-effect attribute, updating the effect accordingly.

| Function | Description |
|---|---|
hypeDocument.refreshReactiveContent() |
Refreshes the content and visibility of elements based on custom data properties. |
hypeDocument.refreshReactiveContentDebounced() |
Debounced version of refreshReactiveContent. Refreshes the content and visibility of elements based on custom data properties. |
hypeDocument.resolveClosestScope(elm) |
Resolves the closest data scope for the provided element. |
hypeDocument.enableReactiveCustomData(data) |
Enables reactive custom data for the Hype document, making it update automatically when custom data properties change. |
These commands are part of the Hype Reactive Content Library and are accessible through the hypeDocument object.
| Function | Description |
|---|---|
HypeReactiveContent.setDefault(key, value) |
Allows overriding a global default by key or if an object is given as key to override all default at once. |
HypeReactiveContent.getDefault(key) |
Returns the value of a default by key or all default if no key is given. |
HypeReactiveContent.enableReactiveObject(obj, callback, _key) |
Makes an object reactive and fires a callback on set operations. Returns the object as a proxy. |
HypeReactiveContent.disableReactiveObject(obj) |
Makes an object non-reactive. Returns the object as a non-reactive object. |
HypeReactiveContent.debounceByRequestFrame(fn) |
Debounces a function by requestAnimationFrame. Returns the debounced function. |
(1) When using Hype Reactive Content, changes made to child elements with data-content or data-visibility attributes will propagate upwards in the DOM, triggering any custom behavior or action specified in the corresponding data-content-changed-behavior, data-visibility-changed-behavior, data-content-changed-action, or data-visibility-changed-action attributes. This means that if a child element's content or visibility changes, any parent elements with these custom attributes will be updated accordingly.
