Node.js built-in modules famously are not promise-based.
This is for historical reasons, as those modules were created before promises were a thing.
We’ve had promisify for quite some time, but I recently found out Node.js provides a new API that’s promise-based.
I thought it was new but it’s been introduced in Node.js 10 (2018, it’s been a while!).
At the moment it only works for the
fs built-in module.
I’m not sure if this will be ported to other native modules soon.
Here’s how to use it:
import * as fs from 'node:fs/promises';
| Note the
node:fs convention which can be now used to identify native modules
Now you can use any of the
fs methods using promises or await:
const posts = await fs.readdir('content')
