I'm trying to use named pipes in my application. The problem is when I try to connect to the named pipe before the server is running, I get the following error:
events.js:141
throw er; // Unhandled 'error' event
^
Error: connect ENOENT \\?\pipe\\testpipe
at Object.exports._errnoException (util.js:870:11)
at exports._exceptionWithHostPort (util.js:893:20)
at PipeConnectWrap.afterConnect [as oncomplete] (net.js:1062:14)
How can I check if the pipe exists before attempting to connect to it?
Note: Wrapping my connect code in a try-catch
doesn't prevent the error.
Here is my code:
var net = require('net');
var addr = '\\\\?\\pipe\\testpipe';
var client = net.createConnection({ path: addr }, function() {
console.log("Connected");
client.on('data', function(data) {
console.log("Recieved: " + data);
});
client.on('error', function(){
console.log(arguments);
});
}.bind(this));
Using the domain
module prevents a fatal error. The following code can be used to safely run the connect code.
Not what I was hoping for, but the closed solution since there have been no answers.
var net = require('net');
var domain = require('domain');
var addr = '\\\\?\\pipe\\testpipe';
var d = domain.create();
d.on('error', function(err) {
console.error(err);
});
d.run(function() {
var client = net.createConnection({ path: addr }, function() {
console.log("Connected");
client.on('data', function(data) {
console.log("Recieved: " + data);
});
client.on('error', function(){
console.log(arguments);
});
}.bind(this));
});
