Node.JS error code meanings? (Specifically fs)

Question

Does anyone know what all of the error codes mean for Node.js, particularly the fs package?

I've looked all over, and can't find any documentation that gives me a list of error codes and their meanings.

Answer 1

Here's some links that should help. Not sure there's a single page out there that has this information catalogued clearly.

• uv.h defines most (all?) of them with a brief description. I think this is the best link I found in my brief github search.
• uv-errno.h lists most of the UV error codes. libuv is the cross-platform async I/O library node uses.
• How libuv maps windows system errors to uv errors
• the node_constants.cc file has a bunch more

Answer 2

Many of the errors seem to mirror the original Linux / POSIX / C errors. See http://man7.org/linux/man-pages/man3/errno.3.html
