Use Express Async Errors Instead of Try/Catch

This express-async-errors package help eliminate the need for try/catch blocks and handles everything under the hood for us. It automatically sends exceptions to error handling middleware. Less code compared to [Use Try/Catch with Async/Await].

Add in at app.js

const config = require('./utils/config')
const express = require('express')
require('express-async-errors')
const app = express()

Without try/catch block

blogsRouter.post('/', async (request, response) => {
  const body = request.body
  const blog = new Blog({
    title: body.title,
    author: body.author,
    url: body.url
  })
  const savedBlog = await blog.save()
  response.json(savedBlog)
})
