While working on Your First Commit Ever, there arised a requirement in which I had to update/change the URL’s query paramter based on the user input.
To give a primer, this app contains an only input where a user can enter their GitHub username and once hit Enter, the app would fetch the very first commit of that particular user using GitHub Developer API like so.
Now, I wanted change the URL’s query parameter based on the entered input. So, for example if user enter
amitmerchant1990, the app should append
?user=amitmerchant1990 to the URL. So, the URL will become “https://www.amitmerchant.com/your-first-commit-ever/?user=amitmerchant1990”.
This is because I wanted to make the URLs sharable. The app would fetch the results based on the
user param as well.
So, to update the query parameter, I used the following code.
let searchParams = new URLSearchParams(window.location.search); searchParams.set("user", githubUserName); window.location.search = searchParams.toString();
Then, it would set the
user param using the
set method of the
And then, it would set the updated parameters once again by assining
This will update the existing
user parameter or append
user parameter if doesn’t exist in the query string.
This works even when there’s no query parameters at all!
