Typescript with Mongoose EXEC() function async/await

Question

I am trying to use Typescript with Express and Mongoose. So far the result has been amazing. I am however stuck at a very minor part.

Premise: I am executing a Mongoose Query using EXEC()

let result = await UserModel.User.find().exec();

I have to use the async / await as there is some processing after this line and I want to avoid callbacks throughout

Problem

I need to get the {err, data} from the result object returned by the query. However currently it simply holds the entire data and I am not able to perform the error handling

So need a way to get the mongoose error description when I use async/await

Did you promisify this method : UserModel.User.find().exec(); . Doesnt this return a callback ?? — Balaji V

Error handling using async/await is done by using try/catch:

try {
  let result = await UserModel.User.find().exec();
  ...
} catch(err) {
  ...
}

Try using the library await-to-js

Example:

const to = require(‘await-to-js’).default

const [err, result] = await to(func()) if (err) throw err
