Run powershell script on windows remote machine from Node.js code

You can use nodejs child_process spawn module for spawning a ssh process and then execute the batch or bash file, if you are in windows machine this code makes it for you:

const { spawn } = require("child_process");

const ssh = spawn(
    "powershell",
    ["ssh", "user@remoteserverip", "powershell path/to/batch/file"]
    );

ssh.stdout.on("data", data => {
    // Do whatever you want with stream of data from server
    console.log(data.toString());
});

ssh.stderr.on("data", err => {
    // Do whatever you want with err from execution of batch script
    console.error(err);
});

ssh.on("exit", code => {
    if(code === 0){
        // Process successfully ended so you can chain anything 
    }
    // Do whatever you want with other codes that process sends
})

If you are in a windows machine you need to spawn Powershell or Command Prompt process. Keep in mind that Powershell must be in path of environment variables and if you want to use Command Prompt you need to spawn process with a /c flag like spawn("cmd", ["/c", "other cammands"])

And if you on an UNIX machine like Linux or Mac just spawn the process directly like below:

const ssh = spawn(
    "ssh",
    ["user@remoteserverip", "powershell path/to/batch/file"]
    );

And the rest is the same.
