nodejs下 electron 使用 Web Termination

想在工具里面执行 shell 进行部分命令行交互

基于微软开源的 xterm.js 和 nodepty

https://github.com/microsoft/xterm.js 前端

https://github.com/microsoft/node-pty 后台

index.html 文件

<!doctype html>
<html>
  <link rel="stylesheet" href="node_modules/xterm/css/xterm.css" />
  <body>
    <div id="terminal"></div>
  </body>
  <script>
    // No idea what these are about. Just copied them from the demo code
    window.require = window.parent.require;

    var global_xterm = undefined;
    var global_pty = undefined;
    function testbtnclick(){
        var os = require(‘os‘);
        var process = require(‘process‘);
        var pty = require(‘node-pty‘);
        var Terminal = require(‘xterm‘).Terminal;

        var FitAddon = require(‘xterm-addon-fit‘).FitAddon

        // Initialize node-pty with an appropriate shell
        const shell = process.env[os.platform() === ‘win32‘ ? ‘COMSPEC‘ : ‘SHELL‘];
        console.log("shell = " + shell);
        console.log("process.env = ", process.env);
        const ptyProcess = pty.spawn(shell, [], {
            name: ‘xterm-color‘,
            cols: 80,
            rows: 34,
            cwd: process.cwd(),
            env: process.env
        });

        // Initialize xterm.js and attach it to the DOM
        const xterm = new Terminal({
            cols: 80,
            rows: 34,
            cursorBlink: true,
        });
        xterm.open(document.getElementById(‘terminal‘));
        global_xterm = xterm;
        global_pty = ptyProcess;

        const fitaddon = new FitAddon();
        xterm.loadAddon(fitaddon);
        fitaddon.fit()

        // Setup communication between xterm.js and node-pty
        xterm.onData(data => ptyProcess.write(data));
        ptyProcess.on(‘data‘, function (data) {
            xterm.write(data);
        });
    }

    function shellEnter(workpath){
        if (global_pty){
            global_pty.write("cd " + workpath +"\n");
            setTimeout(() => {
                global_pty.write("fastlane deliver \n");
            }, 2);
        }
    }
  </script>
</html>

一定要注意 nodepty 和 electron 的版本要对应上否则会有各种各样的报错当初在这里纠结了将近3天简直崩溃。

node-pty 有对应 nodejs 的版本还有对应 electron 的版本无法通用

这里贴出我 package.json 文件, 这里标记了 electron node-pty 和 nodej 对应的版本

{
    "name": "fileinfotool",
    "version": "0.1.0",
    "main": "main.js",
    "scripts": {
        "rebuild": "electron-rebuild -f -w node-pty"
    },
    "dependencies": {
        "electron": "^5.0.11",
        "iconv-lite": "^0.5.0",
        "node-pty": "^0.8.1",
        "xterm": "^4.1.0",
        "xterm-addon-fit": "^0.2.1",
        "image-size": "^0.7.4"
    },
    "devDependencies": {
        "electron-rebuild": "^1.8.6"
    }
}
