Project Summary

In this project, we will create a DevMountain swag shop using react-router-dom. The logic for the shop will already be built out. We will complete this project by building out a router and adding Links.

Setup

• Fork and clone this repository.
• cd into the project.
• Run npm i to install the required dependencies.
• Run npm start to spin up the development server.

Step 1

Summary

In this step, we will install react-router-dom and start configuring our store's router.

Instructions

• In your terminal, run npm i --save react-router-dom when in the root directory of the project.
• Open src/router.js.
• Import React from react.
• Import Switch and Route from react-router-dom.
• Create an empty export default statement using ( ).
• Import the following components:
  • Store - This component will be the landing page of our store.
    • src/components/Store/Store.js
  • Details - This component will be a page that displays more details about a product.
    • src/components/Details/Details.js
  • Checkout - This component will be a page where the user can checkout.
    • src/components/Checkout/Checkout.js
• Inside the parentheses return a Switch component with nested Route components:
  • Store:
    • Set the path prop of this component to "/".
    • Add the exact prop to this component.
    • Set the component prop of this component to { Store }.
  • Details:
    • Set the path prop of this component to "/details/:id".
    • Set the component prop of this component to { Details }.
  • Checkout:
    • Set the path prop of this component to "/checkout".
    • Set the component prop of this component to { Checkout }.

Solution

src/router.js

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

import Store from './components/Store/Store';
import Details from './components/Details/Details';
import Checkout from './components/Checkout/Checkout';

export default (
  <Switch>
    <Route component={ Store } path="/" exact />
    <Route component={ Details } path="/details/:id" /> 
    <Route component={ Checkout } path="/checkout" />
  </Switch>
)

Step 2

In this step, we will modify our index.js to use a router. We'll do this by importing HashRouter from react-router-dom and including it in the ReactDOM.render statement.

Instructions

• Open src/index.js.
• Import HashRouter from react-router-dom.
• Wrap the Provider component in ReactDOM.render with a HashRouter component.

Solution

src/index.js

import React from 'react';
import ReactDOM from 'react-dom';
import App from './components/App';
import registerServiceWorker from './registerServiceWorker';

import { HashRouter } from "react-router-dom";
import { Provider } from "react-redux";

import store from './store';

ReactDOM.render(
  <HashRouter>
    <Provider store={ store }>
      <App />
    </Provider>
  </HashRouter>, 
  document.getElementById('root')
);
registerServiceWorker();

Step 3

Summary

In this step, we will modify our App.js to render our router onto the DOM.

Instructions

• Open src/components/App.js.
• Import router from src/router.js.
• Render router above <Cart />.

Solution

src/components/App.js

import React from 'react';
import './App.css';

import Nav from './Nav/Nav';
import Cart from './Cart/Cart';

import router from '../router';

export default function App() {
  return (
    <div>
      <Nav />
      <div id="App__mainContainer">
        <div id="App__routerContainer">
          { router }
          <Cart />
        </div>
      </div>
    </div>
  )
}

Step 4

Summary

In this step, we will begin to wire up our routes in our store. We'll begin with the Nav component.

Instructions

• Open src/components/Nav/Nav.js.
• Import Link from react-router-dom.
• Locate the element with className of Nav__label:
  • Wrap this element in a Link component.
  • The Link component should use a to prop that equals "/".
  • Assign a className of navLink to the new Link component.
• Locate the element with the id of Nav__checkoutContainer:
  • Wrap this element in a Link component.
  • The Link component should use a to prop that equals "/checkout".
  • Assign a className of navLink to the new Link component.

Solution

src/components/Nav/Nav.js

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

import './Nav.css';

import ShoppingCart from 'react-icons/lib/fa/shopping-cart';

function Nav( { items } ) {
  return (
    <div id="Nav__container">
      <div id="Nav__linksContainer">
        <Link className="navLink" to="/">
          <span className="Nav__label">Store</span>
        </Link>

        <Link className="navLink" to="/checkout">
          <div id="Nav__checkoutContainer">
            <div id="Nav__itemsInCart"> { items } </div>
            <ShoppingCart id="Nav__shoppingCart" />
          </div>
        </Link>
      </div>
    </div>
  )
}

function mapStateToProps( state ) {
  return {
    items: state.cart.length
  };
}

export default connect( mapStateToProps )( Nav );

Step 5

Summary

In this step, we will use route parameters to navigate to a detailed page for each product.

Instructions

• Open src/components/Store/Product/Product.js.
• Import Link from react-router-dom.
• Locate the img element:
  • Wrap the element in a Link component.
  • The Link component should us a to prop that equals { `/details/${id}` }
• Locate the span element with the value of { title }:
  • Wrap the element in a Link component.
  • The Link component should use a to prop that equals { `/details/${id}` }
  • Assign a className of StoreProduct__navLink to the new Link component.

Solution

src/components/Store/Product/Product.js

import React from "react";
import { Link } from "react-router-dom";
import './Product.css';

export default function Product( { id, title, img, price, addToCart } ) {
  return (
    <div id="StoreProduct__container">
      <Link to={ `details/${ id }` }>
        <img src={ img } alt="Product" width="200px" height="139.39px" />
      </Link>
      <div id="StoreProduct__details">
        <div id="StoreProduct__title">
          <Link to={ `/details/${ id }` } className="StoreProduct__navLink">
            <span> { title } </span>
          </Link>
        </div>
        <div id="StoreProduct__addToCart" onClick={ () => { addToCart( id ) } }>
          <span> ${ price } </span>
          <span> Add to Cart </span>
        </div>
      </div>
    </div>
  )
}

Step 6

Summary

In this step, we will add a link to our Details component that will allow us to navigate back to the main store page.

Instructions

• Open src/components/Details/Details.js.
• Import Link from react-router-dom.
• Locate the p element with the value of < Back to store:
  • Wrap this element in a Link component.
  • This Link component should have a to prop that equals "/".
  • Assign an id of Details__storeLink to the new Link component.

Solution

src/components/Details/Details.js

import React from "react";
import { addToCart } from "../../ducks/reducer";
import { connect } from "react-redux";
import { Link } from "react-router-dom";

import './Details.css';

function Details( { swag, history, addToCart } ) {

  function addAndRedirect() {
    addToCart( swag.id );
    history.push('/');
  } 

  return (
    <div id="Details__container">
      <Link to="/" id="Details__storeLink">
        <p> { '<' } Back to store </p>
      </Link>
      <img id="Details__img" src={ swag.img } alt="Product" width="400px" />
      <p id="Details__title"> { swag.title } </p>
      <p id="Details__price"> ${ swag.price } </p>
      <button id="Details__addToCart" onClick={ addAndRedirect }> Add to Cart </button>
      <p> { swag.description } </p>
      <p> { swag.promo } </p>
    </div>
  )
}

function mapStateToProps( state, ownProps ) {
  const swag = state.swag.filter( swag => swag.id === ownProps.match.params.id )[0];
  return { swag };
}

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

Step 7

Summary

In this step, we will update our Cart component to be able to link to the details page for any product.

Instructions

We are going to be editing two files in this step. Try to complete them both on your own.

src/components/Cart/Product/Product.js:

In this component we'll update the products that appear in the cart to be able to route to the details page for that product. The element we'll want wrapped in a Link component is the div with the id of CartProduct__container. The link component should link to the Details component and use a parameter to link the correct product. ( Hint: Look at the parameters of the function ). This link component should also have a id of "CartProduct__navLink".

src/components/Cart/Cart.js:

In this component we'll update the blue checkout button to be able to route to the checkout page. The element we'll want wrapped in a Link component is the div with the id of Cart__footer. The link component should link to the Checkout component. This link component should also have an id of Cart__navLink.

Solution

src/components/Cart/Product/Product.js

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

import './Product.css';

export default function Product( { title, img, id } ) {
  return (
    <Link to={ `/details/${id}` } id="CartProduct__navLink">
      <div id="CartProduct__container">
        <img alt="Product" src={ img } width="70px" height="70px" />
        <span id="CartProduct__title"> { title } </span>
      </div>
    </Link>
  )
}

src/components/Cart/Cart.js ( not entire file )

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

<Link to="/checkout" id="Cart__navLink">
  <div id="Cart__footer" onClick={ this.toggleCartDetails }>
    <span> Checkout </span>
  </div>
</Link>
