Execute shell commands using nodejs with root access

Question

I want to execute the following shell commands inside a nodeJs application. If i am doing the work manually, the commands are as following:

sudo su
password
1 command that needs a root access
exit

Any idea or a code snippet will be helpful

Answer 1

You can combine all 4 commands into one by Ref: Super User answer

echo "<password>" | sudo -S "<command that needs a root access>"

In your NodeJs code - try one of the following:

• Pure JS way

var command='echo "<password>" | sudo -S "<command that needs a root access>"';
child_process.execSync(command)

• Using Library shell-exec - helper library which uses child_process.spawn

const shellExec = require('shell-exec')
var command='echo "<password>" | sudo -S "<command that needs a root access>"';
shellExec('echo Hi!').then(console.log).catch(console.log)

Be sure to validate the command that need to be executed, before triggering execute to avoid unwanted results.
