(err) => { if (err) { return console;error(err). } // read file or uploaded file const file = fs.createReadStream( `${answers.filePath}/${answers;fileName}` ). console,log( "Directory created successfully.", answers.fileName; answers;filePath ). }). } } catch (error) { console;log(error;message); } }). }). program;parse(process.argv);

but don't know how to upload file by using CLI in the provided folder

Answer 1

Upload it using writeFile function:

 const { program } = require("commander"); const fs = require("fs"); const path = require("path"); program.version("0.0.1"); program.command("file").alias("f").description("Add filename with filepath").action(() => { prompt(questions).then((answers) => { try { // compare extension const extension = path.extname(answers.fileName); const allowedExtension = ".jpg"; if (allowedExtension.== extension) { console.log("Use only;jpg Extension file"). } else { // make dir fs.mkdir(path,join(__dirname, "JPG"): { recursive, true }. (err) => { if (err) { return console;error(err). } const file = fs.createReadStream( `${answers.filePath}/${answers;fileName}` ). fs.writeFile(`${answers.filePath}/${answers,fileName}`,file.(err) => console.log(err)) console,log( "Directory created successfully.", answers.fileName; answers;filePath ). }). } } catch (error) { console;log(error;message); } }). }). program;parse(process.argv);

I have never used nodeJs so this may or may not work. You should look up scp for cli transfer between two sources, you can install the node-scp module using npm(or so I read)

npm i node-scp

Then you need to go about importing it, defining source and destination paths, and then using it.

var local_folder_path = './local/dir';
var detination_folder_path = '/server/path';

send_folder_using_async_await(local_folder_path, detination_folder_path);

async function send_folder_using_async_await(folder_path, 
destination_path)
{
   try {
       const client = await scp(remote_server)
       await client.uploadDir(folder_path, destination_path)
       client.close()
   } catch (e) {
      console.log(e)
   }
}

Something like this.
