windows system suspend in powerhell in javascript

To suspend the Windows system using PowerShell in JavaScript, you can use the child_process module in Node.js. Here is an example code snippet:

index.tsx
const { exec } = require("child_process");

// function to suspend Windows system
function suspendSystem() {
  exec("powershell.exe -Command \"& {rundll32.exe powrprof.dll,SetSuspendState 0,1,0}\"", (error, stdout, stderr) => {
    if (error) {
      console.error(`exec error: ${error}`);
      return;
    }
    console.log(`stdout: ${stdout}`);
    console.error(`stderr: ${stderr}`);
  });
}

// call suspendSystem function
suspendSystem();

This code uses the exec() method of the child_process module to call the powershell.exe executable and run a command to suspend the system using the SetSuspendState function of the powrprof.dll library. The 0,1,0 parameters mean to suspend the system immediately, to allow the system to wake on any events, and to force suspend even if there are open applications or unsaved data. You can adjust these parameters as needed for your use case.
