No more try.....catch

Hey, 👋 how are you ?

Are you a back-end developer, handling multiple database operations & tasks or having custom promises written or has a service which returns a promise, and you have to handle it using the ugly try..catch block which might have one block containing several lines of code ? 🤔

Solution 🛠

There is a npm module available which reduces complexity and introduces better readability just as if it's all synchronous in nature. It's called await-to-js. 😍

It's an async await wrapper which focuses on making the task of error handling easier. The output from the function is a de-structured output with error and data, which can be further used independently.

Usage ✍️

const to = require('await-to-js').default;

const getNotificationToken = async (userId) => {
  const [err, token] = await to(redis.get(userId))

  if (err) {
     // Handle your error
  }

  return token
}

This is a simple function which returns a token from redis for a particular user.

My Thoughts 💭

One should consider this to get started with less bugs while handling promises.

Signing off... ✌️
