promisified

Promisified Node.js

This is a simple module to save you from manually calling util.promisify.

For every Node.js module that contains async functions, there is an equivalent module in promisified where those functions have been promisified using util.promisify.

const fs = require('promisified/fs');

async function main() {
  const data = await fs.readFile('data.txt', 'utf8');
}

main().catch(e => {
  console.error(e);
  process.exit(1);
});

Note that in some cases there are already promisified versions built into Node.js itself, such as fs.promises, also available as require('fs/promises') in Node.js v14. This package does not use those; it always uses util.promisify.
