node.js - suggestion on workflow and tools to work with node.js

Question

I'm developing some really simple node.js libraries for learning purposes.

It's about functions like HexToBase64 and things like that.

Ideally, I'd like to program in a text editor, and play with it on the node repl, having the code automatically reloaded on the repl on every save.

Any module or tool to interactively play with node?

有诸如supervisor、nodemon和forever之类的模块可以在代码更改时重新加载您的应用程序。否则，您可以像这样创建自己的实现：

var fs = require('fs');
var cluster = require('cluster');

if (cluster.isMaster) {
  var worker = cluster.fork();

  fs.watch(process.argv[1], function(event, filename) {
    worker.kill();
    worker = cluster.fork();
  });
}

if (cluster.isWorker) {
  // put your application logic here that will
  // run when this file changes
}

至于交互式使用 Node，您可以node在终端中运行，并且您有一个交互式控制台。如果您需要加载脚本并以交互方式使用它，那么您将使用.load script.js.
