- Part 10: Our First Component
This week, we’re creating a simple Header
component. We aren’t getting into the nitty-gritty of adding auth just yet. Today’s goal is to get the basic layout of our Header
. Before we begin, run yarn start
in your terminal to open your application in the browser.
Stub the Component
Create a new file in your src/components
folder called Header.js
. Add a simple functional component.
import React from 'react';
const Header = () => {
return (
<div>
COVIDiary
</div>
);
};
export default Header;
Import the Header
Let’s add our Header
to App.js
.
In src/App.js
:
import Header from './components/Header';
Just after the opening <div>
In the render()
section, add our component:
<Header />
You can remove all the default React code if you’d like. I moved it into a main
tag so I had a placeholder between my header and footer.
<main>
<img src={logo} className="App-logo" alt="logo" />
<p>
Edit <code>src/App.js</code> and save to reload.
</p>
<a className="App-link" href="https://reactjs.org" target="_blank" rel="noopener noreferrer">
Learn React
</a>
</main>
Right now, your project will look something like this:
Fill in the Details
Let’s start to format our header to match our wireframe sketch. From here on out, we’re working in components/Header.js
.
For our header, we will be using React-Bootstrap’s NavBar
and Nav
components. To begin, import the components at the top of your file:
import Navbar from "react-bootstrap/Navbar";
import Nav from "react-bootstrap/Nav";
Now, let’s replace our div
with NavBar
. We’ll pass it props to adjust the styling.
<Navbar expand='md' bg='dark' variant='dark' as='header'>
{/*expand - breakpoint at which hamburger menu expands*/}
{/*bg - sets background color*/}
{/*variant - use dark color scheme for dark bg*/}
{/*as - converts default <div> tag to <header> tag*/}
</Navbar>
Within our Navbar
, let’s put our site’s name on the left. You could also use a logo here, if you had one. We’ll have this element link to our root page.
<Navbar.Brand href="/">COVIDiary</Navbar.Brand>
We also want to make sure our Navbar
is responsive so it will adapt when users adjust their screen sizes.
<Navbar.Toggle aria-controls="responsive-navbar-nav"/>
Finally, let’s add the main navigation links. We want them to collapse into a hamburger menu on smaller screens, so we will wrap them in a <Navbar.Collapse>
component. Note the id and className come straight from the React-Bootstrap documentation.
<Navbar.Collapse id="responsive-navbar-nav">
<Nav className="ml-auto" as='nav'>
{/*ml-auto - aligns nav links to the right of the container*/}
<Nav.Link href="/about">About</Nav.Link>
<Nav.Link href="/register">Register</Nav.Link>
</Nav>
</Navbar.Collapse>
Our basic header is complete! Here it is on medium and larger screens:
Here is the hamburger menu on small screens:
And here is the expanded hamburger menu:
Coming Up
Now that we’ve got our Header
component, we’re ready to get into some more complicated aspects of our front end!
