Phase 1 Mock Code Challenge: Ramen Rater

Learning Goals

• Access information from an API using a GET request and use it to update the DOM
• Listen for user events and update the DOM in response

Introduction

Today you'll be building an app for rating ramen. You will be using a local API and building out the frontend for our app.

Demo

Use this gif as an example of how the app should work.

Setup

• Run json-server --watch db.json to get the backend started
• Open the index.html file on your browser
• Write your code in the index.js file
• As you are writing your code out and completing the deliverables ensure that it works on the DOM and passes the tests by running mocha in a new terminal in the same directory

Endpoints

Your base URL for your API will be: http://localhost:3000

The endpoints you may need are:

• GET /ramens
• GET /ramens/:id

Feel free to add any additional classes or ids to any elements in the HTML file as you see fit.

Core Deliverables

As a user, I can:

• See all ramen images in the div with the id of ramen-menu. When the page loads, fire a function called displayRamens that requests the data from the server to get all the ramen objects. Then, display the image for each of the ramen using an img tag inside the #ramen-menu div.
• Click on an image from the #ramen-menu div and fire a callback called handleClick to see all the info about that ramen displayed inside the #ramen-detail div (where it says insert comment here and insert rating here).
• Attach a submit even listener to the new-ramen form using a function called addSubmitListener. After the submission, create a new ramen and add it to the#ramen-menu div. The new ramen does not need to persist; in other words, if you refresh the page, it's okay that the new ramen is no longer on the page.

** Attention here **: Your program should have a main() function that invokes displayRamens and addSubmitListener after the DOM has fully loaded and start the program logic.

Advanced Deliverables

These deliverables are not required to pass the code challenge, but if you have the extra time, or even after the code challenge, they are a great way to stretch your skills.

Note: If you are going to attempt these advanced deliverables, please be sure to have a working commit with all the Core Deliverables first!

As a user, I can:

• See the details for the first ramen as soon as the page loads (without clicking on an image)
• Update the rating and comment for a ramen by submitting a form. Changes should be reflected on the frontend. No need to persist. You can add this HTML to the index.html file to create the edit form:

<form id="edit-ramen">
  <h4>Update the Featured Ramen</h4>
  <label for="rating">Rating: </label>
  <input type="number" name="rating" id="new-rating" />
  <label for="new-comment">Comment: </label>
  <textarea name="new-comment" id="new-comment"></textarea>
  <input type="submit" value="Update" />
</form>

• Delete a ramen (you can add a "delete" button if you'd like, or use an existing element to handle the delete action). The ramen should be removed from the ramen-menu div, and should not be displayed in the ramen-detail div. No need to persist.

Extra Advanced Deliverables

You'll need these endpoints for the advanced deliverables:

• POST /ramens
• DELETE /ramens/:id
• PATCH /ramens/:id

As a user, I can:

• persist my updates to a ramen's rating and comment. (PATCH request)
• persist new ramens that I create (POST request)
• persist any ramen deletions (DELETE request)
