You can find the full code for this tutorial at https://codesandbox.io/s/url-params-dnql1.
AirBnB example
Let's take a live example to better understand URL params and unique IDs in URLs. Go to AirBnB and click on any room or apartment for rent. Pay attention to the URL of the page. You'll see the base URL, www.airbnb.ca (or www.airbnb.com). Then, you'll see /rooms, which is the path. Finally, there's the ID of the room itself. In the image below, the ID of this specific apartment is 49381739.
AirBnB URL example
Although AirBnB is built on Ruby on Rails, the same concept can be applied to a React application when we want unique IDs.
Create a router
In App.js, create your router. You can learn how to do so in the Reach Router tutorial. For now, I only have my Home page.
// App.js
import React from "react";
import { Router } from "@reach/router";
import Home from "./Home";
const App = () => {
return (
<Router>
<Home path="/" />
</Router>
);
};
export default App;Create a Course page
Create a course page, which is a template for each course that we'll have. I also added a Link at the bottom of the page, so users can go back to Home.
// Course.js
import React from "react";
import styled from "styled-components";
import { Link } from "@reach/router";
import backgroundImage from "./background.png";
const Course = () => {
return (
<div>
<h1>Course page</h1>
<Link to="/">Go back Home</Link>
</div>
);
};
export default Course;Update the router
Import your Course component in the App.js file.
// App.js
import Course from "./Course";In your body, add the Course component with a path that leads to /courses/:courseId. The :courseId part is the parameter (the course ID) that we'll pass to the component when we'll be calling it.
// App.js
<Course path="/courses/:courseId" />Update Home
Back in Home, we'll use Link and add a few links to a few courses with different IDs.
// Home.js
import { Link } from "@reach/router";// Home.js
<Link to="/courses/1111">Go to course ID 1111</Link>
<Link to="/courses/2222">Go to course ID 2222</Link>
<Link to="/courses/3333">Go to course ID 3333</Link>Update Course
Let's update our course component so that we can display the course's ID through the props. To access it, we do props.courseId. Note that courseId should be the same as the param you provided in your router before.
// Course.js
import React from "react";
import styled from "styled-components";
import { Link } from "@reach/router";
import backgroundImage from "./background.png";
const Course = (props) => {
return (
<div>
<h1>Course ID {props.courseId}</h1>
<Link to="/">Go back Home</Link>
</div>
);
};
export default Course;Now, when you navigate to a specific course, you'll see its ID in the page itself!
