Node/Express Lesson 6 Coding Assignment

Create a new git branch called week6. This should be created when the week5 branch is active, so that it adds to week 5. Continue to work in the node-express-course/03-task-manager/starter directory. You duplicate the work of the instructor in the video.

Additional Assignment

Create a file in the starter directory called QuizAnswers2.txt. Put answers to the following questions in it.

1. In this lesson, you created a middleware function called asyncWrapper. Why?
2. Suppose that you want to make sure that both a status code and and error message are send back to the user when they request the URL for a task that does not exist. Assume that you’ve created a CustomAPIError class and an error handler that references that class. Complete the code:

const getTask = asyncWrapper(async (req, res, next) => {
    const { id: taskID } = req.params;
    const task = await Task.findOne({ _id: taskID });
    if (!task) {
    // your code here
    }
    res.status(200).json({ task });
});

As you will see in the lessons that follow, you do not have to create the asyncWrapper middleware, because you can instead use an NPM package called express-async-errors that provides the capability.
