I am getting the EMFILE error when I am trying to read a bunch of files to
search for user provided strings. I understand that its because node is
running out of file descriptors with too many files open but i cant seem to
find any good solution for this. Is there any design pattern to limit the
number of open files. The only thing I have come across is to increase the
number of open descriptors but I am hoping for a programmatic solution.
Also since all i am doing here is reading the files to make a match for a
given string how different that is from doing an actual grep child process,
i didnt go that route becoz I wasnt able to figure out how to get grep
working .. I think i tried something like
var grep = spawn('grep', [matchStr, dirPath, filePrefix]);
and it didnt seemed to work.
Any comments would be appreciated.
