Have you ever been faced with a stacktrace that looks like this?
TypeError h is not a function. (In 'h()', 'h' is undefined)
main.jsbundle:954:5353
main.jsbundle:112:423 p
main.jsbundle:112:1740
main.jsbundle:112:423 p
main.jsbundle:112:898 n

main.jsbundle:50:205 c
main.jsbundle:50:1623 b

...perhaps from production from a minified web JS bundle or a React Native error report.
stacktracify takes a source map and a stack trace from your clipboard (or from a file) and outputs a readable stacktrace with proper line numbers for each line
Example output:
TypeError h is not a function. (In 'h()', 'h' is undefined)

npm install -g stacktracify
Copy a minified stacktrace to your clipboard - then run:
stacktracify /path/to/js.map
Can also read stacktrace from file. For more info:
stacktracify --help
- https://github.com/gabmontes/source-map-cli (only takes one line at a time)
- https://github.com/janekp/mapstrace (not a CLI, not easy to use for any stack trace)
