node_stream_handler

Unlike HTTP, services such as SMTP and POP have multiple exchanges between the client and the server before disconnecting. node_stream_handler simplifies exchanges like that by emitting a line event every time a specified delimiter is sent by the remote server.

Install

npm install node_stream_handler

Example

This is a simple POP3 login and listing.

var   util = require('util')
    , StreamHandler = require('stream-handler')
;

var stream = new StreamHandler('example.com', 110);
stream.on('line', function(line) {
    console.log('Received Line: ' + line);
});
stream.on('error', function (err, excp) {
    console.log(excp);
});

//Catch the welcome message
stream.once('line', function(line) {
    console.log('Got Welcome: ' + line);
    //Catch the OK from the USER command
    stream.once('line', function(line) {
        if (line == '+OK') {
            //Catche the OK from the PASS command
            stream.once('line', function(line) {
                console.log('Requesting LIST');
                stream.write('LIST' + "\r\n");
            });
            console.log('Sending Password');
            stream.write('PASS MyPassword' + "\r\n");
        }
    });
    console.log('Logging In');
    stream.write('USER info@example.com' + "\r\n");
});
