I'm making a game server and I would like to type commands after I run the server from SSH. For example: addbot, generatemap, kickplayer, etc.
Like in Half-life or any other gameserver. How can I make Node.js listen to my commands and still keep the server running in SSH?
You can use process.stdin like this:
process.stdin.resume();
process.stdin.setEncoding('utf8');
process.stdin.on('data', function (text) {
console.log(text);
if (text.trim() === 'quit') {
done();
}
});
function done() {
console.log('Now that process.stdin is paused, there is nothing more to do.');
process.exit();
}
Otherwise, you can use helper libraries like prompt https://github.com/flatiron/prompt which lets you do this:
var prompt = require('prompt');
// Start the prompt
prompt.start();
// Get two properties from the user: username and email
prompt.get(['username', 'email'], function (err, result) {
// Log the results.
console.log('Command-line input received:');
console.log(' username: ' + result.username);
console.log(' email: ' + result.email);
})
