Browser Compatibility

Reef works in all modern browsers. That means:

The latest versions of Edge, Chrome, Firefox, and Safari.
Mobile Safari, Chrome, and Firefox on Safari.
WebView, Chrome, and Firefox for Android.

If you need to support older browsers, you’ll need to transpile your code into ES5 with BabelJS.

Changelog

You can find all available versions under releases.

Version 8 (current version) brings more predictability and convenience when building interactive UIs.

Added reef-checked, reef-selected, and reef-value attributes (and reef-default-* versions) for more predictable form field behavior.
Added new helper methods for more accurate type checking and throwing errors.
Improved DOM diffing under-the-hood.
Fixed router issues with module bundlers.
Improved control for route titles.
Dropped legacy browser support.

Version 7 introduces new tools for managing more complex applications.

Added new Reef.Store() data store constructor for reactive shared state.
Added getter and setter functions for more fine-grained control over how data flows in and out of components.
Improved process for attaching nested components to parent components.
Removed the clone() method on individual components (the global Reef.clone() method still exists).

Version 6 completely changes how data reactivity works.

Component data is now directly reactive.
The setData() and getData() methods (previously used for reactivity) have been removed.
You can get an immutable copy of your data with the clone() method.
Added an emit() method for emitting custom events.
IE support now requires polyfills or transpiling.

Version 5 adds new build system and filename structure,

Specific named versions for ES modules, AMD, and CommonJS.
Default build is browser-only.
ES modules now natively supported.

Version 4 adds better performance and XSS protection.

Data is once again automatically encoded to help protect you from cross-site scripting (XSS) attacks.
Changes to diffing and rendering reduce reflows and improve performance.
Support pushed back even further to IE9.
Deprecated: Custom sanitizer methods were removed in favor of built-in, automated HTML encoding. You can still add custom sanitization within template functions.

Version 3 removes built-in sanitization.

Automatic sanitization has been removed. HTML templates are unsanitized by default.
Two new hooks to add sanitization to your components have been added. This provides more developer flexibility and keeps Reef as lightweight as possible.

Version 2 adds a better sanitizing engine and markup support.

DOMPurify is now the template sanitizing engine.
The attribute exceptions feature has been removed in favor of DOMPurify’s configuration options. The addAttributes() and removeAttributes() methods no longer exist.
Reef now offers a smaller unsafe version for UIs that don’t use any third-party or user-provided content. It does not sanitize templates before rendering, so use with caution.
SVGs are now properly supported and will render correctly.

Version 1 removed polyfill dependencies.

All polyfills have been removed and are no longer needed. This is a breaking change, as the .polyfill versions of scripts no longer exist.

Version 0.2 introduced some big new features.

Data reactivity and automatically updating UI
Support for nested components
Shared state support (with data reactivity!)
Custom attribute exceptions for your templates
