DiSCLAIMER: Since i'm not going to develop or support this anymore, you'd better check @andersnm's vscode-sourcemap-helper as successor and a better alternative.
VSCode Source Maps Navigator is a VSCode extension that allows you to quickly navigate to the original source code directly from transpiled/generated one.
The extension is also provides an ability to open the source map itself (both inline maps and map files are supported) by Ctrl/Cmd+click on source map URL.
Currently there is only one command available:
Navigates (opens in separate tab) original source of transpiled/generated file from current tab with cursor, located at corresponding location.
After navigating from generated file to original one, backward navigation is also becomes available.
