如何将命令传递到node.js服务器？

Question

I have a question about running a node.js server. After I have started a server using node server.js , I want to pass a javascript command to the running server. In the same manner that the developer tools console works in a browser, I want to be able to enter a command and have the server execute it. For example, if I have a game server running, and I want to kill a certain player, I could enter into some sort of CLI player.kill(); and the server will execute that command as it is entered. Is this possible? thanks.

You can use VorpalJS for this scenario. Vorpal is a framework for building immersive CLI applications built on an interactive prompt provided by inquirer.js.

 const vorpal = require('vorpal')(); vorpal .command('mycommand1', 'Outputs "bar".') .action(function(args, callback) { this.log('bar'); callback(); }); vorpal .delimiter('mygame$') .show(); 

When you execute the above script it creates a new prompt "mygame$" then you can execute the command "mycommand1" in that prompt interactively which can then be passed on to your server.
