I would like to increase the call stack limit for my node process so that I can create, parse and serialize a recursive object that's about 100,000 layers deep. If I had more time, I should represent this in a better format.
But for a quick fix, there is a suggested solution to do something like:
/bin/bash -c "ulimit -s $n; exec /usr/local/bin/node --stack-size=$n app.js"
Are there any repercussions that I need to worry about?
Just use node --stack-size=2048 app.js or any other amount in kbytes. But keep in mind, that this is not a production way. Higher value you'll put - more unstable app could become.
As noted by others, be aware that increasing this value may lead to a segmentation fault. Looking at the bigger picture, increasing stack size may not solve all your issues. When writing recursive functions in node, your best strategy is to write them in a tail-recursive manner, since node supports proper tail calls. This will eliminate stack size overflows.
