React Router

In this activity we will add React Router to the Books application in order to render a book details page as well as a no match 404 page.

Instructions

• Open the Unsolved folder and install dependencies by running yarn install at the project root.

• Start the app by running yarn start from the project root.

• Once the app starts open your browser to localhost:3000.

• Open App.js.

Part 1

• Set up React Router inside of the client/src/App.js file.

  • The / and /books routes should both render the Books component page.

Part 2

• Notice that inside of the pages folder we have a NoMatch component. This is the component for our 404 page.

• Add a route for the new NoMatch component. This should only render if no other routes are matched. e.g. /sjdfhjsdhfjsa or /notarealroute/lalala should both render the NoMatch component page.

  • You will need to use the Switch component from the React Router Dom library to accomplish this. An example can be found here.

Part 3

• Notice that in the pages folder we have a Detail component. This component displays additional information about a book.

• Add a route for the the new Detail component. This should render when the /books/:id path is matched. e.g. if a book's _id is 59a39cf2549cf482c814333f, then /books/59a39cf2549cf482c814333f should render its book Detail page.

• Inside of the Detail component, add code so that when the component mounts, we retrieve the book for the rendered route and save it to this.state.book. e.g. when the route is /books/59a39cf2549cf482c814333f, an AJAX request should be made to get the book with an _id of 59a39cf2549cf482c814333f. If completed successfully, you should see the book's synopsis on this page.

  • You may need to look into URL params with React Router to accomplish this.

  • To access props in a class component you must use this.props instead of props.

Hints

• Parts 1 - 2 will only require you modify the client/src/App.js file.

• The React Router DOM library should already be installed.

• The React Router documentation is your friend!

• Ask the instructor or a TA if you're having difficulty understanding any of the activity requirements.
