This is a visualization of JavaScript/CSS source map data, which is useful for debugging problems with generated source maps. It's designed to be high-performance so it doesn't fall over with huge source maps.

Right clicks on the minify code. Select Source Map Visualization in the context menu.

Or press ⌘ ⇧ P in the vscode and type Source Map Visualization.

Supported source map:

1. Inline base64 source map. //# sourceMappingURL=data:application/json;base64,
2. External source map url. //# sourceMappingURL=index.js.map
3. Sibling code and source map. index.js and index.js.map.
4. Guess possible source map. index.js and index.map.

You can select partial code in the editor. This is useful when you want to visualize the source map of a specific <script> tag in html.

You can copy and paste the code to the existed Source Map Visualization panel.
