✅ Step 01. Add Dynamic Pages! 🚀

Open in CodeSandbox 📤

LEARNING GOALS 🥅

• Learn about the render prop pattern to add more control of what Route is rendering.
• Learn about the .push method on the history object.

Instructions

1. Refactor Add component to include a form to add new ideas.
2. Build out a helper function to handle form submissions.
3. Pass the API method - handleAddIdea to the Add component using the render prop, and invoke it inside the form's onSubmit handler.
4. Use the history .push method to push the user home after submitting an idea.
5. Refactor the Home component to show the ideas as an ordered list of Link components that take the user to the idea's voting page.
6. Add a ternary expression to render the ideas if the ideas.length > 0 otherwise, display a nice message - "Looks like there are no ideas!"

✅ Step 02. Add a Jam Idea Voting Page 🎟

Open in CodeSandbox 📤

LEARNING GOALS 🥅

• Learn about how to add URL parameters.
• Learn about the match object.

Instructions

1. Add a new Route to catch the /ideas/<unique-id>.
2. Build out the Vote component to be rendered at /ideas/<unique-id>.
3. Use the getIdea and handleVote API methods to render the idea's likes and title data, and add the button click behavior, respectively.
4. Add a conditional to handle ideas id's that are not in our backend.

✅ Step 03. Polish up the Application 💅

Open in CodeSandbox 📤

LEARNING GOALS 🥅

• Learn about the NavLink component.

Instructions

1. Add activeStyle to the navigation links so that when clicked the styling of the link changes accordingly.
2. Add emojis next to the like number depending on the like count. For example, if the like count is less than 0 we display a 💩, equal to zero - ⭐️, and greater than zero - 🌶.

✅ Step 04. BONUS (ADVANCED) Add Private Routing! 🔒

Open in CodeSandbox 📤

LEARNING GOALS 🥅

• Learn about Higher Order Components
• Learn about the Redirect component
• Learn about how to pass state into Redirect.

Instructions

1. Add a Login component that will render a form with a dropdown menu of usernames.
2. Invoke the auth.setAuthUser API method inside the form's onSubmit handler function.
3. Add the auth.unsetAuthUser API method as the onClick handler on the logout button. Additionally, show the authUser name somewhere in the NavBar.
4. Build a Higher Order Component called PrivateRoute that invokes the render callback if the user is authenticated otherwise, return a Redirect component to take the user to the login page.
5. Add the authUser to the second argument of handleAddIdea inside of the Add component's onSubmit handler. Display the author inside of the Vote component.
6. Pass referrer state into the Redirect component rendered by PrivateRoute so that after logging into the application the user is redirected to the originally requested page instead of /.
