Sending text JSON over node.js socket how to deal with '\n\r' simbols

Question

I have client - server application, server side on Node.js client on flash, communicating with each other by socket. I write stringifyed JSON to socket, and on server read data:

    socket.on('data', function(data) {
        console.log(JSON.parse(data.toString());
        var json = JSON.parse(data.toString()) });

Everything was OK, until I started to send to server JSON with long text messages containing '\n\r'. On that I getting error:

SyntaxError: Unexpected end of input

because '\n\r' means end of the pack. Delete '\n\r' from text isn't the good way cause I need it to show text correctly. Please give me best way to deal with that problem. Thanks in advance.

use JSON.stringify(data) instead of .toString()

One easy way would be to try to parse, if not, then wait for more data:

var json = '';

socket.on('data', function(data) {
    try {
        json = JSON.parse(data);
    } catch (e) {
        json += data;

        try {
            json = JSON.parse(json);
            // Now it's fine.
        } catch (e) {
            // Wait for more.
            return;
        }
    }

    // Now it's fine.
    // At the end do;
    json = '';
});

Thanks alot I think it's easiest and best approach, works fine even with several '\n\r'.
