Debugging CoffeeScript line-by-line

Question

Is there a way to debug CoffeeScript line-by-line?

I understand that it compiles into Javascript. But this sounds like it could make it a pain to debug.

Answer 1

Yes, with node-inspector:

npm install -g node-inspector

By putting the statement debugger into the source code of your script, you will enable a breakpoint. Then type in a console:

coffee -c -m myscript.coffee
node-debug myscript.js

Node Inspector supports source-maps out of the box, so no extra configuration is needed.
