从npm全局模块生成文件到用户的当前路径

Question

I am creating a NPM module that will be installed globally on my computer, let's say it reside inside <my-global-npm-module> and inside of this folder I have my index.html file.

Goal: My goal is to copy the index.html file and paste into whatever/location folder my user is using, example: my-app folder.

I have the following .js code:

const fs = require('fs'); //File Server
const path = require('path');

let filename = 'index.html';
let src = path.join(__dirname, filename);
let destDir = path.join(__dirname, 'BlueFolder');

fs.access(destDir, (err) => {
  if(err) 
    fs.mkdirSync(destDir);  
  copyFile(src, path.join(destDir, filename));
});

function copyFile(src, dest) {

  let readStream = fs.createReadStream(src);
  readStream.once('error', (err) => {
    console.log(err);
  });

  readStream.once('end', () => {
    console.log('File has been copied.');
  });

  readStream.pipe(fs.createWriteStream(dest));
}

If run this .js file it will copy and paste a new copy of the index.html file inside of BlueFolder which is also inside of my <my-global-npm-module> folder. The correct should be inside of my user's folder, example: my-app folder.

The function you are looking for is process.cwd() . This function returns the current working directory as a string.

From the documentation :

The process.cwd() method returns the current working directory of the Node.js process.
