LAB | React IronNutrition

Introduction

You just realized that since the beginning of the bootcamp, your diet is not healthy and it may have an impact on your health (and productivity), now and in the long term.

To take care of the food you eat, you decided to create a nutrition app that will track everything you eat!

Getting Started

Clean the App.js component so that it has the following structure:

// src/App.js
import './App.css';

function App() {
  return <div className="App"></div>;
}
export default App;

Instructions

Iteration 0 | Setup

Ant Design Installation

We will use Ant Design component library for the design. :)

$ npm install antd

To make the Ant Design styles available in the entire app, import Ant Design stylesheet in index.js:

// src/index.js
import 'antd/dist/antd.css';

Ant Design Components

During the LAB, we will be using a set of simple Ant Design components that provide basic styling.

Before using any Ant Design component, you first have to import it from the antd package. You must import a component in each file where you intend to use it. Example:

// EXAMPLE
// To start using the pre-made Ant Design components we must first import them:
import { Card, Row, Col, Divider, Input, Button } from 'antd';

function Example() {
  // After importing the components we can render them directly:
  return (
    <div>
      <Row>
        <Col>
          <Divider>Fancy Input</Divider>
          <Input value={''} onChange={() => {}} />
        </Col>

        <Col>
          <Card title={'Fancy Card'}>
            <Button onClick={() => {}}>Fancy Button</Button>
          </Card>
        </Col>
      </Row>
    </div>
  );
}

Import a JSON

For now, we will be working on the App.js file. In the later steps, you can refactor the app and split it into multiple components. Import the array of foods from the foods.json file to App.js.

import foods from './foods.json';

About the design

If you struggle with the design, you can find static examples of what is expected inside the style-guide/ folder.

So let's start!

Iteration 1 | Render a Simple List

Now that you have the foods.json imported in App.js it is time to save it in a state variable. Once you have done that, map over the state variable and render a simple list that displays food names. Use the following snippet for the list items:

<div>
  <p> FOOD_NAME_HERE </p>
  <img src="FOOD_IMAGE_HERE" width={0} />
</div>

Iteration 2 | Create the `FoodBox` component

Create a new component named FoodBox that takes the prop food, which is an object. It should display the card with food information coming from the food prop. To render the content, use the structure provided in the file style-guide/FoodBox.example.js.

Once done, test it by rendering a single instance of the component in App.js. You can pass it the object with food info like this:

<FoodBox food={ {
  name: "Orange",
  calories: 85,
  image: "https://i.imgur.com/abKGOcv.jpg",
  servings: 1
}} />

Expected result:

Iteration 3 | Render a List of `FoodBox` Components

After creating the FoodBox component, use it in App.js to render the food list. Instead of mapping over the foods array and rendering only the food names, render the <FoodBox /> component. When rendering the FoodBox component, remember to pass the food object as a prop.

Once you are done rendering the FoodBox in the list, your app should display the following content:

Iteration 4 | Add new food

Create a new controlled component named AddFoodForm, used to add new foods. The component should contain a form with four input elements for name , image , calories and servings.

The component should render use the AntDesign component Input instead of the the input tag. The AntDesign Input component uses the same syntax as the regular input tag. Example:

// HTML <input /> tag
<input value={} type="text" onChange={} />

// Ant Design <Input /> component
<Input value={} type="text" onChange={} />

The component should be rendered in the App.js.

The food should be added to the list when the user clicks submit.

Hint: To add new food to the food array that is in the state of the App component, you must pass a function through the props.

Iteration 5 | Implement search bar

Create a Search component to search through and filter the list of food items displayed.

Iteration 6 | Create a delete button

Your FoodBox component has a delete button. Implement the delete functionality so that the item gets removed from the food list when a user clicks on the delete button.

Hint: To update the food array that is in the state of the App component, you will need to pass a function through the props.

If you are not sure how to create responsive columns with Ant Design, you can check the example provided in the Ant Design documentation.

Iteration 7 | Bonus | Hide the Add Food Form

There are quite a few components displaying in the app. Implement a hide/show button that, when clicked, hides/shows the AddFoodForm.

When the form is showing, the button should display the message Hide Form`. When the form is hidden it shoud display Add New Food.

Iteration 8 | Bonus | Display a Feedback Message

Display a Feedback message to the user when the food array is empty. Once the user deletes all of the items from the list, the following message should be displayed:

Happy coding! ❤️
