How to add asynchronous Node.js module exports?

Spread the love

To add asynchronous Node.js module exports, we use promises.

For instance, we write

module.exports = (async () => {
  const db = await require("./db");
  const foo = "bar";

  return {

in foo.js to export the promise returned by the async function.

Then we import it by writing

(async () => {
  const foo = await require("./foo");

to call require to require foo.js, which exported the promise returned by the async function.

We use await to get the object returned by the promise.
