Question 1

How to style JSON Viewer to match my website's theme?

Accepted Answer

Override the CSS custom properties documented in the README, such as --background-color or --string-color, in your own stylesheet. You can also use shadow parts like ::part(key) for more precise control over elements.

Question 2

Can I use JSON Viewer in a React app?

Accepted Answer

Yes, since it's a Web Component, you can import it directly and use the <json-viewer> tag. For better integration, you might create a React wrapper to handle props and events, but no native bindings are provided.

Question 3

JSON Viewer vs react-json-view – which should I choose?

Accepted Answer

JSON Viewer is best for its framework-agnostic Web Component design and high customization via CSS. If you're building a React app and want pre-styled, tightly integrated components without CSS work, react-json-view might be more convenient.

Question 4

How to handle click events on JSON nodes in JSON Viewer?

Accepted Answer

You can attach event listeners to the component or use the experimental custom renderer to return clickable elements like links. For example, override customRenderer to wrap values in <a> tags with event handlers.

Question 5

Is JSON Viewer accessible for screen readers?

Accepted Answer

The README doesn't mention accessibility features, so you may need to add ARIA attributes manually or ensure keyboard navigation. Consider testing with assistive technologies and enhancing the component if accessibility is critical.

Question 6

How to filter JSON data dynamically in JSON Viewer?

Accepted Answer

Use the filter() method with a regex or path string, such as viewer.filter('**.name'), to show only matching nodes. Call resetFilter() to clear it, and combine with search() for highlighting results.
