Source Map Peek
Peek into original source via source maps from the command line when devtools fail.
There are still few cases where source map support fails and you have to debug the huge js bundle.
For example
- Those shitty old browsers
- Long stack traces from promise libraries such as Q or Bluebird
- Some bad test frameworks
- Probably in some other weird setups too
Source Map Peek is a small bandage for these situations. It allows you to view and access the original source using source maps from the command line.
