socketerrors

node-socketerrors

Exposes a function mapping socket errors to SocketError objects subclassing httperrors.

The defined SocketError objects are created via createerror.

Installation

Make sure you have node.js and npm installed, then run:

npm install socketerrors

Usage

The primary use case is wrapping errors originating from socket operations:

var http = require('http');
var socketErrors = require('socketerrors');

http.get('nonexistent').on('error', function (err) {
    var socketError = socketErrors(err);

    console.warn(socketError.toString()); // ECONNREFUSED: connect ECONNREFUSED
});

Other errors will be marked as not being socket errors:

var socketErrors = require('socketerrors');

var err = new Error();
var socketError = socketErrors(err);

if (socketError.NotSocketError) {
    // what am I?
}
