Angular 调试

我们新建一个项目。执行 ng server 会启动一个网站。

1. 执行 where ng 。看看ng 是什么.

D:\Abp学习\angular\Mytest>where ng
C:\Users\QiGongbo\AppData\Roaming\npm\ng
C:\Users\QiGongbo\AppData\Roaming\npm\ng.cmd

实际执行到了ng.cmd：

@IF EXIST "%~dp0\node.exe" (    # C:\Users\QiGongbo\AppData\Roaming\npm\\node_modules\@angular\cli\bin\ng
  "%~dp0\node.exe"  "%~dp0\node_modules\@angular\cli\bin\ng" %*
) ELSE (
  @SETLOCAL
  @SET PATHEXT=%PATHEXT:;.JS;=;%
  node  "%~dp0\node_modules\@angular\cli\bin\ng" %*
)

这个 ng 是个JS文件。 文件是这样的：

#!/usr/bin/env node
‘use strict‘;

// Provide a title to the process in `ps`.
// Due to an obscure Mac bug, do not start this title with any symbol.
console.log(process);
try {
  process.title = ‘ng ‘ + Array.from(process.argv).slice(2).join(‘ ‘);
} catch(_) {
  // If an error happened above, use the most basic title.
  process.title = ‘ng‘;
}

// Some older versions of Node do not support let or const.
var version = process.version.substr(1).split(‘.‘);
if (Number(version[0]) < 8 || (Number(version[0]) === 8 && Number(version[1]) < 9)) {
  process.stderr.write(
    ‘You are running version ‘ + process.version + ‘ of Node.js, which is not supported by Angular CLI v6.\n‘ +
    ‘The official Node.js version that is supported is 8.9 and greater.\n\n‘ +
    ‘Please visit https://nodejs.org/en/ to find instructions on how to update Node.js.\n‘
  );

  process.exit(3);
}

require(‘../lib/init‘);

最后引用了  require(‘../lib/init‘);

init.js 如下：
