如何在MEAN堆栈中执行Shell命令行？

Question

Hello I'm a very newbie in MEAN stack.

Previously I used php for web development, and I usually used "shell_exec" to browse server json files and read them.

How can I execute shell command line in MEAN stack?

What is "shell_exec" in MEAN stack?

Thanks in advance :)

If you need to browse json - it's much simplier:

const data = require('./some-file.json');

In case if you still need exec, here it is:

const { exec } = require('child_process');
exec('cat *.js bad_file | wc -l', (error, stdout, stderr) => {
  if (error) {
    console.error(`exec error: ${error}`);
    return;
  }
  console.log(`stdout: ${stdout}`);
  console.log(`stderr: ${stderr}`);
});
