In the labs throughout this section, we'll be working on building a small portfolio site in React.
Our goal for the first lesson is to get the basic components for our app — the
<Navbar>, <Home>, and <About> components — to be returned from the <App>
component.
Once we're done, we should get something like this:
For this lab, we will be rendering a few children components in our top-most
component: App. All of our work will be done in src/components/App.js. The
rest of the files shouldn't need any changes.
To set up the app and run it in the browser, run:
$ npm install $ npm start
To start, work on getting the app to match the screenshot above. Then, open up a
second terminal (open to the same directory), and runnpm test to check your
work.
Two components, <Navbar> and <Home>, are already defined in the App.js
file. Add both of these components as child components of <App> by
including them in the return statement for the App function.
Create a third component, <About>. The <About> component should also be a
child component of <App>.
<About> component should return a <div> with an id of about. To
match the screenshot, the div should contain an <h2> element with the text
"About." However, as long as it has an id of about, it will pass the test!Hint: If you're stuck, try using the screen.debug method in the test file
to see what DOM elements are being returned by your <App> component. If you
still need help, this lab (and others) have a solution branch on GitHub
where you can see one possible solution to this lesson.
