Not receiving stdout from nodejs spawned process

Question

I\'m trying to have nodejs interact with adventure, an old text based game. The idea is to open adventure as a child process and then play the game by writing

Answer 1

The data passed is a buffer type, not a string. Therefore, you need a decoder to read that buffer and then do the logging.

Here's how to do that.

var StringDecoder = require('string_decoder').StringDecoder;
var decoder = new StringDecoder('utf8');

child.stdout.on('data', function (data) {
    var message = decoder.write(data);
    console.log(message.trim());
});
