在NodeJS进程中创建bash包装器

I want to build a tiny script that being run should create a bash-like session (in the current bash session, where the process is created), that can be used later for some mad science (e.g. piping to browser).

我想构建一个运行的小脚本应该创建一个类似bash的会话（在当前的bash会话中，创建进程），以后可以用于某些疯狂的科学（例如管道到浏览器）。

I tried using pty.js, piping stdin to the bash process, and data from the bash session to the stdout stream:

我尝试使用pty.js，管道stdin到bash进程，以及从bash会话到stdout流的数据：

var pty = require("pty.js");

var term = pty.spawn('bash', [], {
  name: 'xterm-color',
  cols: process.stdout.columns,
  rows: process.stdout.rows,
  cwd: ".",
  env: process.env
});

term.pipe(process.stdout);
process.stdin.pipe(term);

term.on("close", function () {
    process.exit();
});

This works, but it's very buggy:

这有效，但它非常错误：

For example, the non-characters (directional keys, tab etc) are not caught.

例如，未捕获非字符（方向键，选项卡等）。

I also tried using spawn, this not being so bad, but still buggy.

我也试过使用spawn，这不是那么糟糕，但仍然是马车。

var spawn = require("child_process").spawn;

var bash = spawn("bash");
bash.stdout.pipe(process.stdout);
process.stdin.pipe(bash.stdin);

Is there a better solution how to create a bash wrapper in NodeJS?

有没有更好的解决方案如何在NodeJS中创建bash包装器？

You might want to put the standard input into raw mode. This way all the key strokes will be reported as a data event. Otherwise you only get lines (for every press of the return key).

您可能希望将标准输入置于原始模式。这样，所有击键都将被报告为数据事件。否则你只能获得一行（每按一次返回键）。

process.stdin.setEncoding('utf8');
process.stdin.setRawMode(true);      

var pty = require('pty.js');

var term = pty.spawn('bash', [], {
   name: 'xterm-color',
   cols: process.stdout.columns,
   rows: process.stdout.rows,
   cwd: '.',
   env: process.env
});

term.pipe(process.stdout);
process.stdin.pipe(term);

term.on('close', function () {
    process.exit();
});
