Project Summary

In this project we will be building an ecommerce shop for the sale of JavaScript libraries. Using React Router we'll set up and navigate between the various views required. Take some time to familiarize yourself with the provided components:

• App will be the top level component for our application.
• Nav will be the top navigation bar.
• Landing will be the home page displayed when the application first loads.
• Shop will be the main shop page, displaying the items available.
• Details will be the view in which a user views a single product's information.
• Cart will be the user's cart.

Several of these have child components that are used to display products in different ways.

This project uses Redux, which is a different way of managing data in things like React. We'll be teaching how to use Redux later in the course. For the time being, we've provided all the necessary Redux code. In this project, Redux is getting pieces of data from a larger pool of data, and assigning it to the this.props of a given component.

Setup

• Fork and clone this repository.
• cd into the project directory.
• Run npm i to download the included dependencies.
• Run npm test to start the test suite.
• Run npm start to spin up the development server.

Step 1

Summary

To begin our project, we will be installing the required dependencies and configuring the router.

Instructions

• Install React Router.
• Create a new file in src/ named router.js.
• Configure a router in src/router.js:
  • Import Switch and Route from react-router-dom.
  • Import the following components to use as routes:
    • src/components/Landing/Landing.js
    • src/components/Shop/Shop.js
    • src/components/Details/Details.js
    • src/components/Cart/Cart.js
  • Use the following combinations of paths and components for your router:
    • Path: "/" - Component: Landing - This path should be exact.
    • Path: "/shop" - Component: Shop.
    • Path: "/details/:name" - Component: Details.
    • Path: "/cart" - Component: Cart

Detailed Instructions

To begin, run npm i react-router-dom --save to install and save React Router to the package.json. Once that installs, create a new file in src/ named router.js. This file will be where we create and configure our router. To begin creating our router we'll need to import React from React ince we will be using JSX to declare our routes.

import React from 'react';

The next thing we'll need to import is react-router-dom. We'll need Route and Switch from react-router-dom. Route is the default component used for defining a new route. Switch is a component for determining which route to display.

import React from 'react';
import { Route, Switch } from 'react-router-dom';

We'll also need to import the components that will server as an individual view/router. The components we'll want are: Cart, Details, Landing, and Shop.

import React from 'react';
import { Route, Switch } from 'react-router-dom';

import Cart from './components/Cart/Cart';
import Details from './components/Details/Details';
import Landing from './components/Landing/Landing';
import Shop from './components/Shop/Shop';

Now that we have all our imports we can focus on creating the router. We can do this by exporting JSX. The top level element will be our Switch component from react-router-dom. Create an export default statement underneathe all the import statements.

export default (
  <Switch>

  </Switch>
)

We can then add our views/routes inside the Switch component by using the Route component from react-router-dom. For example, if I wanted to render the Landing component it would look like:

export default (
  <Switch>
    <Route component={ Landing } exact path="/" />
  </Switch>
)

The code snippet above means that when the path of our browser is at "/" on our website it will render the Landing component.

What is exact? Exact allows us to specific in React Router v4 that we only want that component to render when the path is exactly "/". If we had a development server running on port 3000, that would mean the landing component would only render at: http://localhost:3000/.

Let's add the rest of our views/routes. Don't worry about using exact on these routes. The remaining components to render are: Cart, Details, and Shop.

export default (
  <Switch>
    <Route component={ Landing } exact path="/" />
    <Route component={ Shop } path="/shop" />
    <Route component={ Details } path="/details/:name" />
    <Route component={ Cart } path="/cart" />
  </Switch>
)

The code snippet above translates to:

• Say the server is hosted locally on port 3000.
• A user goes to http://localhost:3000/ in their browser -> The Landing component will render.
• A user goes to http://localhost:3000/shop in their browser -> The Shop component will render.
• A user goes to http://localhost:3000/details/someNameGoesHere in their browser -> The Details component will render.
• A user goes to http://localhost:3000/cart in their browser -> The Cart component will render.

Solution

src/router.js

import React from 'react';
import { Switch, Route } from 'react-router-dom';

import Cart from './components/Cart/Cart';
import Details from './components/Details/Details';
import Landing from './components/Landing/Landing';
import Shop from './components/Shop/Shop';

export default (
  <Switch>
    <Route component={ Landing } exact path="/" />
    <Route component={ Shop } path="/shop" />
    <Route component={ Details } path="/details/:name" />
    <Route component={ Cart } path="/cart" />
  </Switch>
)

Step 2

Summary

In this step, we will take the router we just configured in src/router.js and add it to our application in src/index.js.

Instructions

• Open src/index.js.
• Import BrowserRouter from react-router-dom.
• Wrap the Provider component in a BrowserRouter component.
• Open src/components/App.js.
• Import router from src/router.js.
• Underneath the Nav component render the router JSX.

Detailed Instructions

Now that our router is configured in src/router.js, we need to wrap our application in a BrowserRouter component to make use of those routes. Open up src/index.js and import BrowserRouter from react-router-dom. Then inside of ReactDOM.render wrap the Provider component in a BrowserRouter component.

import { BrowserRouter } from "react-router-dom";

ReactDOM.render(
  <BrowserRouter>
    <Provider store={ store }>
      <App />
    </Provider>
  </BrowserRouter>,
  document.getElementById( "root" )
);

All that is left is actually rendering our router's JSX. Let's open src/components/App.js. Import router from src/router.js and render it just beneath <Nav />. Because we are rendering the router inside of App, that means App will always be visible! This is useful, because we want to display the top navigation bar on every page, and now we only have to render it once.

import router from '../router';

export function App( { children } ) {
  return (
    <div className="app">
      <Nav />
      { router }
    </div>
  );
}

Solution

You should now see the Landing component by default, and have the ability to navigate to different routes via the address bar. Try manually visiting all the different routes and make sure they are working.

src/index.js

import React from "react";
import ReactDOM from "react-dom";
import { Provider } from "react-redux";
import { BrowserRouter } from "react-router-dom";

import "./index.css";

import store from "./store";

import App from "./components/App";

ReactDOM.render(
  <BrowserRouter>
    <Provider store={ store }>
      <App />
    </Provider>
  </BrowserRouter>,
  document.getElementById( "root" )
);

src/components/App.js

import React from "react";

import "./App.css";

import Nav from "./Nav/Nav";
import router from '../router';

export function App( { children } ) {
  return (
    <div className="app">
      <Nav />
      { router }
    </div>
  );
}

export default App;

Step 3

Summary

In this step, we will be setting up the Landing component to display data and link to other views.

Instructions

• Open src/components/Landing/Landing.js.
• Import FeaturedProduct from src/components/Landing/FeaturedProduct/FeaturedProduct.js.
• Import Link from react-router-dom.
• Modify the h1 for "Take me to the full shop!":
  • This element should be wrapped in a Link element.
  • The Link element should have a prop called to that equals "/shop".
  • The Link element should have a className prop that equals "landing__full-shop-link".
• Before the return statement of the Landing function:
  • Create a variable called products that equals a mapping over featuredProducts.
  • The map should have one parameter called product.
  • The map should return the following JSX for each product:
    • JSX

      <FeaturedProduct
        addToCart={ () => addToCart( product.id ) }
        description={ product.description }
        key={ product.id }
        logo={ product.logo }
        name={ product.name }
        onSale={ product.onSale }
        price={ product.price }
      />

• Render products inside the div with the className of landing__products-wrapper.
• Open src/components/Landing/FeaturedProduct/FeaturedProduct.js.
• Import Link from react-router-dom.
• Update all the comments with the appropriate prop.
• Modify the h3 element with the className of featured-produce__name:
  • This element should be wrapped in a Link element.
  • The Link element should have a to prop that equals { `/details/${name}` }.
• Modify the p element with the className of featured-product__price-reduced:
  • This element should be inside a ternary statement.
  • If onSale is truthy, render the p element.
  • If onSale is not truthy, use null.

Detailed Instructions

So we have routes now but no way to get to those routes from the interface. Let's fix that by updating our Landing component. Open src/components/Landing/Landing.js. At the bottom of the code, you can see mapStateToProps and connect. That is Redux's way of giving this component data. This component will take a products prop that is an array of products that are either featured or on sale.

Let's begin by importing FeaturedProduct from src/components/Landing/FeaturedProduct/FeaturedProduct.js and Link from react-router-dom in src/components/Landing/Landing.js. The Link component is React Router's replacement for an <a> tag which is used to allow the library better control over routing.

import { Link } from "react-router-dom";
import FeaturedProduct from './FeaturedProduct/FeaturedProduct';

Near the bottom of the return, wrap the h1 with the className of landing__full-shop-link in a Link. Link will take one prop called to that should equal "/shop".

<Link className="landing__full-shop-link" to="/shop">
  <h1 className="landing__full-shop-link">Take me to the full shop!</h1>
</Link>

Our h1 element on the Landing component will now route to the Shop component when clicked on.

Now let's work on getting products to actually show up. At the top of the Landing function create a new variable called products. This should equal the result of mapping over featuredProducts and returning the following JSX:

<FeaturedProduct
  addToCart={ () => addToCart( product.id ) }
  description={ product.description }
  key={ product.id }
  logo={ product.logo }
  name={ product.name }
  onSale={ product.onSale }
  price={ product.price }
/>

When combining the JSX with the map function it'll look like:

const products = featuredProducts.map( (product) => (
  <FeaturedProduct
    addToCart={ () => addToCart( product.id ) }
    description={ product.description }
    key={ product.id }
    logo={ product.logo }
    name={ product.name }
    onSale={ product.onSale }
    price={ product.price }
  />
)); 

This will create an array of React components for us. More specifically an array of FeaturedProduct components. Since we used a map, each featured product will have all the information related to that product.

We are now ready to render our products onto the landing page. Locate the div with the className of landing__products-wrapper. Inside that div render our products.

<div className="landing__products-wrapper">
  { products }
</div>

The products should now be rendering on the page. However, the data is not being populated into the FeaturedProduct component. Let's take a look at the FeaturedProduct.js file and make sure it's using the props as the data source. Open up src/components/Landing/FeaturedProduct/FeaturedProduct.js and import Link from React Router.

import { Link } from "react-router-dom";

Now let's replace the commented our sections with the appropriate props. If you notice our props have been destructured using es6. We can tell this happening based on the code snippet below:

export default function FeaturedProduct( { addToCart, description, logo, name, onSale, price } ) {

Now we can reference each prop inside this function as addToCart, description, logo, name, onSale, and price. After updating all the commented out sections, our return should look like:

return (
  <div className="featured-product">
    <div className="featured-product__logo-name-wrapper">
      <img
        alt={ `${ name } logo` }
        className="featured-product__logo"
        src={ logo }
      />
      <h3 className="featured-product__name">{ name }</h3>
    </div>
    <p className="featured-product__description">{ description }</p>
    <div className="featured-product__buy-wrapper">
      <p className="featured-product__price-reduced">Price Reduced!</p>
      <button
        className="featured-product__buy"
        onClick={ addToCart }
      >
        ${ price }
      </button>
    </div>
  </div>
);

If we take a look at our live-server ( Live server not running? Run npm start when in the root of the project. ) we can see that our landing page is now displaying the correct data for each product. However, it looks like all the prices are reduced and we can't click on the product to go to the details page. Let's fix this. Wrap the h3 tag that holds the product name in a Link component with a to prop that equals { `/details/${name}` }.

return (
  <div className="featured-product">
    <div className="featured-product__logo-name-wrapper">
      <img
        alt={ `${ name } logo` }
        className="featured-product__logo"
        src={ logo }
      />
      <Link to={ `/details/${ name }` }>
        <h3 className="featured-product__name">{ name }</h3>
      </Link>
    </div>
    <p className="featured-product__description">{ description }</p>
    <div className="featured-product__buy-wrapper">
      <p className="featured-product__price-reduced">Price Reduced!</p>
      <button
        className="featured-product__buy"
        onClick={ addToCart }
      >
        ${ price }
      </button>
    </div>
  </div>
);

Now each product will have a link to its own details page. All that's left now is fixing the "Price Reduced!" label to not display for every product. Let's use a ternary statement to only display that p element when onSale is truthy. Otherwise just use null.

return (
  <div className="featured-product">
    <div className="featured-product__logo-name-wrapper">
      <img
        alt={ `${ name } logo` }
        className="featured-product__logo"
        src={ logo }
      />
      <Link to={ `/details/${ name }` }>
        <h3 className="featured-product__name">{ name }</h3>
      </Link>
    </div>
    <p className="featured-product__description">{ description }</p>
    <div className="featured-product__buy-wrapper">
      {
        onSale
        ?
          <p className="featured-product__price-reduced">Price Reduced!</p>
        :
          null
      }
      <button
        className="featured-product__buy"
        onClick={ addToCart }
      >
        ${ price }
      </button>
    </div>
  </div>
);

export function Landing( { addToCart, featuredProducts } ) {
  const products = featuredProducts.map( (product) => (

  , logo: PropTypes.string.isRequired
  , name: PropTypes.string.isRequired
  , onSale: PropTypes.bool
  , price: PropTypes.number.isRequired
};

FeaturedProduct.defaultProps = { onSale: false };

The links should now be setup to go the details route. However, the component is intentionally broken. We will fix this in the next step. If your view looks like the picture above, you are good to go!

Step 4

Summary

In this step, we will set up the Details component. We'll make use of route parameters to display the correct product data. I'll go into more detailed instructions on route paramters in the detail instructions section of this step.

Instructions

• Open src/components/Details/Details.js.
• Import Link from react-router-dom.
• Update the h3 element to link to the Shop component.
• .find the correct product from products
  • Using match, return the single product based on the route.
    • Hint: Add a console.log that logs match. Then go into the interface and click on a route from the landing page. If you open the browser's developer tools, you should see match get logged. Look around this object for any useful property that can indicate what product we need to display information for.
  • Once you have that property value from match use it in combination with a find method to return a single object.
    • Hint: Use find on sproducts. Return the product whose name is equal to the name in our route.
• Use the product object that gets passed in as a paramter to the Details function to update all the commented out sections to the correct property value.
  • Hint: Add a console.log just above the const in the Details function of the value of product. Then go into the interface and click on a route from the landing page. If you open the browser's developer tools, you should see a log that shows an object. If you don't see an object, your .find is working incorrectly in mapStateToProps.
• Create an addToCartAndRedirect function above the return of the Details function:
  • The buy button should be modified to use this new function instead.
  • This function should call the addToCart action creator and pass in id as a parameter.
  • This function should then route the user back to the previous page the user was on.
    • Hint: React Router is providing us with a history object which we can reference as history. This object contains values and methods that we can use to controll our router programmatically. Try to figure out the most efficient way to go back a page.

Detailed Instructions

Let's begin by opening src/components/Details/Details.js. Currently this view is broken and will throw errors if we try to navigate to it. This is because Redux is giving us all the products, but as this is the Details page, we only want to display one specific product.

To fix this we'll need to get access to our route parameters. Our component is passed a match property through props by react-router. This is also equal to an object. If we take a look at that object we'll see it has a property called params that is also equal to an object. This params object contains all the params in our URL.

When we created our route for details we specified we wanted a parameter called name. Because of this if we take a look at match.params (we deconstructed props in the component declaration) we'll see a property called name that equals a string. Since our landing page has three products this name will come in three different forms. You will see match come in these forms:

// Backbone
ownProps = {
  match: {
    params: {
      name: 'Backbone'
    }
  }
}
// React
ownProps = {
  match: {
    parmas: {
      name: 'React'
    }
  }
}
// Vue
ownProps = {
  match: {
    params: {
      name: 'Vue'
    }
  }
}

Knowing this object structure we can combine the value of match.params.name with a .find to get the exact product object we need for our component. Let's write a function that will take the name we get from match.params and search through the products array to find the specific product we want to display.

We have access to products from the props deconstruction. It is an array that contains all the product objects. Let's use a .find on that array to return the object whose name property equals the name property on match.params.name.

const product = products.find( product => product.name === match.params.name )

Now that the component has access to the proper product object we can fill in the commented out sections with the correct data. Since we deconstructed the product object for you, we can look at that to determine what properties are on the product object. The product object will have a description, id, logo, name, and price. Let's add these values to the commented out sections.

return (
  <div className="details">
    <h3 className="details__back-to-shop">Back to shop</h3>
    <img
      alt={ name }
      className="details__logo"
      src={ logo }
    />
  <h1 className="details__name">{ name }</h1>
    <p className="details__description">{ description }</p>
    <button
      className="details__buy"
      onClick={ addToCart( id ) }
    >
      Buy now for ${ price }!
    </button>
  </div>
);

Now when we visit the details of any of the featured products we should see it's data populate the page. Let's focus on the functionality of the component now that we have the data we need. If we take a look at our h3 element we'll notice it needs to be a link back to the Shop component. Let's import Link from react-router-dom and wrap the h3 in a Link that has a prop called to that equals "/shop".

import { Link } from "react-router-dom";

<Link to="/shop">
  <h3 className="details__back-to-shop">Back to shop</h3>
</Link>

A user will now be able to navigate back to the store if they are not interested in the presented product. All that's left is to make our Buy button functional by adding the product to the cart and then routing the user back to the previous page they were on. If we take a look at our Details function it looks like it is taking in a history parameter. This is also something react-router is adding to our application. This object represents the window.History api. On this history object that gets passed in for us, we can see that it has a function called goBack. We can call that function after dispatching our addToCart action.

function addToCartAndRedirect() {
  addToCart( id );
  history.goBack();
}

Don't forget to update the JSX to call this new function instead of the addToCart action creator.

<button
  className="details__buy"
  onClick={ addToCartAndRedirect }
>
  Buy now for ${ price }!
</button>

Solution

src/components/Details/Details.js

import React from "react";
import { connect } from "react-redux";
import { Link } from "react-router-dom";

import "./Details.css"

import { addToCart } from "../../ducks/product";

export function Details( { addToCart, history, products, match } ) {

  const product = products.find( product => product.name === match.params.name )

  const {
    description,
    id,
    logo,
    name,
    price,  
  } = product;

  function addToCartAndRedirect() {
    addToCart( id );
    history.goBack();
  }
  return (
    <div className="details">
      <Link to="/shop">
        <h3 className="details__back-to-shop">Back to shop</h3>
      </Link>
      <img
        alt={ name }
        className="details__logo"
        src={ logo }
      />
    <h1 className="details__name">{ name }</h1>
      <p className="details__description">{ description }</p>
      <button
        className="details__buy"
        onClick={ addToCartAndRedirect }
      >
        Buy now for ${ price }!
      </button>
    </div>
  );
}

function mapStateToProps( state ) {
  return { products: state.products };
}

export default connect( mapStateToProps, { addToCart } )( Details );

Step 5

Summary

In this step, we will set up the top navigation bar to display cart information and provide some links.

Instructions

• Open src/components/Nav/Nav.js.
• Import Link from react-router-dom.
• Wrap the div with a className of nav__header-wrapper in a Link component:
  • The Link component should have a to prop that equals "/".
• Wrap the p element with the className of nav__cart in a Link component:
  • The Link component should have a to prop that equals "/cart".
  • Update the text of the p element to display cartTotal. This value comes from the mapStateToProps function below.

src/components/Nav/Nav.js

import React from "react";
import { connect } from "react-redux";
import { Link } from "react-router-dom";

import "./Nav.css";
import javascriptLogo from "../../assets/javascript.svg";

export function Nav( { cartTotal } ) {
  return (

      <Link to="/">

Step 6

Summary

In this step, we will set up the Shop view and its child components.

Instructions

• Open src/components/Shop/Shop.js.
• Import ProductTile from src/components/Shop/ProductTile/ProductTile.js.
• Create a variable called productTiles above the return of the Shop function:
  • This variable should equal a mapping over products that returns the following JSX:
    • JSX

      <ProductTile
        addToCart={ () => addToCart( product.id ) }
        key={ product.id }
        logo={ product.logo }
        name={ product.name }
        price={ product.price }
      />

• Inside the div with the className of "shop__products-wrapper" render the productTiles variable.
• Open src/components/Shop/ProductTile/ProductTile.js.
• Update the commented out sections to use props.
• Wrap the h3 element in a Link component:
  • The Link component should have a to prop that equals { `/details/${ name }` }.

Detailed Instructions

No detailed instructions for this step! This step is very similar to how we set up the Landing and FeaturedProducts components. Refer back to that to help.

Solution

src/components/Shop/Shop.js

import React from "react";
import { connect } from "react-redux";

import "./Shop.css";

import { addToCart } from "../../ducks/product";

import ProductTile from './ProductTile/ProductTile';

export function Shop( { addToCart, products } ) {
  const productTiles = products.map( (product) => (
    <ProductTile
      addToCart={ () => addToCart( product.id ) }
      key={ product.id }
      logo={ product.logo }
      name={ product.name }
      price={ product.price }
    />
  ));

  return (
    <div className="shop">
      <h1 className="shop__header">Shop</h1>
      <div className="shop__products-wrapper">
        { productTiles }
      </div>
    </div>
  );
}

function mapStateToProps( { products } ) {
  return { products };
}
export default connect( mapStateToProps, { addToCart } )( Shop );

src/components/Shop/ProductTile/ProductTile.js

import React, { PropTypes } from "react";
import { Link } from "react-router-dom";

import "./ProductTile.css";

export default function ProductTile( { addToCart, logo, name, price } ) {
  return (
    <div className="product-tile">
      <section className="product-tile__info">
        <Link to={ `/details/${ name }` }>
          <h3> { name } </h3>
        </Link>
        <button
          className="product-tile__buy"
          onClick={ addToCart }
        >
          ${ price }
        </button>
      </section>
      <section className="product-tile__logo-wrapper">
        <img
          className="product-tile__logo"
          alt={ `${ name } logo` }
          src={ logo }
        />
      </section>
    </div>
  );
}

ProductTile.propTypes = {
  addToCart: PropTypes.func.isRequired,
  logo: PropTypes.string.isRequired,
  name: PropTypes.string.isRequired,
  price: PropTypes.number.isRequired
};

Step 7

Summary

In this step, we will allow users to checkout from the cart view. We will create a new component to thank them for their purchase.

Instructions

• Create a folder in src/components/ called ThankYou.
• Inside the ThankYou folder you just created, create a ThankYou.js file.
• Inside the ThankYou folder you just created, create a ThankYou.css file.
  • CSS

    .thank-you {
      align-items: center;
      display: flex;
      flex-direction: column;
      justify-content: center;
      margin-top: 25px;
    }

• Create a basic react component called ThankYou in src/components/ThankYou/ThankYou.js:
  • Import React from react.
  • Import ./ThankYou.css.
  • Import thanks from src/assets/thanks.gif.
  • The ThankYou component should return the following JSX:
    • JSX

      <div className="thank-you">
        <img
          role="presentation"
          src={ thanks }
        />
        <h3>Thank you for your purchase!</h3>
      </div>

• Open src/router.js.
• Import the ThankYou from src/components/ThankYou/ThankYou.js.
• Create a new route where the path is "/thank-you" and the component is ThankYou.
• Open src/components/Cart/Cart.js.
• Create a function called checkoutAndRedirect just above the return statement:
  • This function should call the checkout action creator.
  • This function should use history.push to route to "/thank-you".
• Update the button with the className of "cart__checkout" to call the checkoutAndRedirect function.

Detailed Instructions

Let's begin by creating a ThankYou component in src/components/ThankYou/ThankYou.js. You'll need to create the ThankYou folder and ThankYou javascript file. Inside the javascript file let's create a basic react component that returns the JSX from the instructions above.

import React from "react";

export default function ThankYou() {
  return (
    <div className="thank-you">
      <img
        role="presentation"
        src={ thanks }
      />
      <h3>Thank you for your purchase!</h3>
    </div>
  )
}

We're now ready to configure a route with this new ThankYou component. Open src/router.js and import the ThankYou component. Then configure a route with a path of "/thank-you" and a component of ThankYou.

import ThankYou from './components/ThankYou/ThankYou';

export default (
  <Switch>
    <Route component={ Landing } exact path="/" />
    <Route component={ Shop } path="/shop" />
    <Route component={ Details } path="/details/:name" />
    <Route component={ Cart } path="/cart" />
    <Route component={ ThankYou } path="/thank-you" />
  </Switch>
)

All that's left is to hook up the button in the Cart view to call the checkout action creator and change the view to ThankYou. Create a new function named checkoutAndRedirect which takes no parameters. This function will invoke the checkout Redux action creator, then invoke history.push( "/thank-you" ).

function checkoutAndRedirect() {
  checkout();
  history.push("/thank-you");
}

Then in the JSX add an onClick attribute that calls checkoutAndRedirect.

<button className="cart__checkout" onClick={ checkoutAndRedirect }>Checkout</button>

Solution

src/components/ThankYou/ThankYou.js

import React from "react";
import './ThankYou.css';

import thanks from '../../assets/thanks.gif';

export default function ThankYou() {
  return (
    <div className="thank-you">
      <img
        role="presentation"
        src={ thanks }
      />
      <h3>Thank you for your purchase!</h3>
    </div>
  )
}

src/router.js

import React from 'react';
import { Switch, Route } from 'react-router-dom';

import Cart from './components/Cart/Cart';
import Details from './components/Details/Details';
import Landing from './components/Landing/Landing';
import Shop from './components/Shop/Shop';
import ThankYou from './components/ThankYou/ThankYou';

export default (
  <Switch>
    <Route component={ Landing } exact path="/" />
    <Route component={ Shop } path="/shop" />
    <Route component={ Details } path="/details/:name" />
    <Route component={ Cart } path="/cart" />
    <Route component={ ThankYou } path="/thank-you" />
  </Switch>
)

src/components/Cart/Cart.js

import React from "react";
import { connect } from "react-redux";

import "./Cart.css";

import { checkout } from "../../ducks/product";

import CartItem from "./CartItem/CartItem";

export function Cart( { checkout, history, productsInCart } ) {
  const products = productsInCart.map( product => (
    <CartItem
      key={ product.id }
      logo={ product.logo }
      name={ product.name }
      price={ product.price }
    />
  ) );
  const cartTotal = productsInCart.reduce( ( total, { price } ) => total + price, 0 );

  function checkoutAndRedirect() {
    checkout();
    history.push("/thank-you");
  }
  
  return (
    <div className="cart">
      <h1>Cart</h1>
      {
        products.length === 0
          ?
            <h3>Nothing in cart! Go buy something!</h3>
          :
            <main>
              { products }
              <div className="cart__total">
                ${ cartTotal }
              </div>
              <button className="cart__checkout" onClick={ checkoutAndRedirect }>Checkout</button>
            </main>
      }
    </div>
  );
}

function mapStateToProps( { products, productsInCart } ) {
  return { productsInCart: products.filter( product => productsInCart.includes( product.id ) ) }
}

export default connect( mapStateToProps, { checkout } )( Cart );
