JavaScript Sequental operation-CodePudding

What is the best way/pattern to perform sequental operations in JS(NodeJS)? E.g. Create folder->copy file->edit file->etc. This is stand-alone app, so thread-blocking oprations is ok(Sync).

CodePudding user response：

Don't. Get in the habit of writing async code in node everywhere, even if it doesn't need to be. It's just good practice, prevents refactoring a bunch of stuff in the future, and with modern JS it's simple to write:

import { mkdir, copyFile } from 'fs/promises';

async function createThing() {
    await mkdir('/path/to/dir');
    await copyFile(src, dest);
    ...
}

CodePudding user response：

Just use async/await for sequential, asynchronous operations. No need to write sync code that you'll regret later. Also, depending on the application, you might get trivial speedup opportunities by doing things concurrently.
