Create and Delete Lab

Objectives

• Implement a Yelp-like application where users can create and delete both restaurants and reviews of each restaurant.

Introduction

In this lab, we will practice creating and removing various items using Redux. We are working with two different resources, restaurants and reviews, with each restaurant having many reviews and reviews belonging to a restaurant. You will implement container components to connect each resource to your Redux store.

Instructions

Restaurants

Start off by working on the components for displaying restaurants. First, you'll need a RestaurantInput component that allows a user to create new restaurants. Your form should have two inputs: a text input to enter the name of the restaraunt, and an input with type equal submit.

Next, you will build out the RestaurantsContainer component that will connect to Redux and pass the appropriate props down to its children. You will then want to create a Restaurants component that renders a list of restaurants, and a Restaurant component that is responsible for each individual restaurant.

Users should also be able to delete restaurants, so you will need to wire up the button rendered in the Restaurant component and give each restaurant an ID. To do that, you may want to use the cuid library that we have already imported into the reducer file for you. Like the uuid library we have used in previous labs, cuid will generate a unique id for you:

import cuid from 'cuid';

console.log(cuid());
// ch72gsb320000udocl363eofy

Restaurants stored in Redux should have text and id keys.

Reviews

Next you will work on the reviews resource. You will make a ReviewInput component that will enable users to create a review that is associated with a specific restaurant. As with the RestaurantInput component, the form should have a text input for the content of the review along with an input of type submit.

Next you will build out the ReviewsContainer, Reviews, and Review components. The ReviewsContainer should be nested within the Restaurant component so reviews are displayed underneath the restaurant they belong to. Users should also be able to delete a specific review.

Note: Take note of the structure of this app: containers can end up anywhere in an app, even nested way down the component tree. This setup can feel a bit counterintuitive initially since we could have a presentational component that has a container component as a child, but the benefit is that none of the non-container components have any code related to Redux! They're just firing props!

Since you'll need to be able to associate reviews to restaurants, and delete specific reviews, reviews stored in Redux should have a text key for the review content, a restaurantId key to associate and display the review with a specific restaurant and an id key unique to the review itself.

Note: Although each review belongs to a specific restaurant, that relationship should be implemented using the restaurantId key, not in the structure of the store's state. In order to get the tests passing, the state will need to be structured as follows:

  {
    restaurants: [],
    reviews: []
  }

Hint: To simplify coding of the manageRestaurant reducer, you may want to use Redux's combineReducers function that was introduced in an earlier lesson.

Conclusion

Once all tests are passing, you'll be able to create and delete restaurants and their specific reviews.

Bonus: Implement edit functionality for restaurants and reviews. You will probably want to include an additional button with each restaurant and review that, when clicked, will open an input where a user could modify the contents of a specific item. You will then need to dispatch an update action to the reducer to update the store.
