System Errors
Node.js generates system errors when exceptions occur within its runtime environment. These usually occur when an application violates an operating system constraint. For example, a system error will occur if an application attempts to read a file that does not exist.
Below are the system errors commonly encountered when writing a Node.js program
- EACCES - Permission denied
- EADDRINUSE - Address already in use
- ECONNRESET - Connection reset by peer
- EEXIST - File exists
