Use Try/Catch with Async/Await

For error handling with async/await, the recommended method to deal with exceptions is using try/catch method. The catch block calls next function and passes request handling to error handling middleware.

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

Above option is good when using a library is not an option. For cleaner code -> [Use Express Async Errors Instead of Try/Catch]
