Vanilla JavaScript Update URL without Refresh

Today we are looking into updating the URL without doing a refresh. We can use the History API to access and modify the URL states.

The cool part is it has superb browser support!

The history API is a set of methods used to manipulate history. For instance, we can go forward and backward, just like clicking the buttons in your browser.

JavaScript history.pushState permalink

Today's focus is on the method called pushState(). We can use this method to push a new entry into the browser's history. It doesn't need a refresh and will show the new URL in the browser.

The history.pushState() method accepts three arguments:

• state: This is an object with details about the URL
• title: The title (usually the <title> attribute)
• url: The actual URL you see in your browser bar.

In code, it would look like this:

history.pushState({ pageID: 'unicorn' }, 'Unicorn', '/unicorn');

You can open up the console and paste the above code into it. And you should see the URL change.

Also, note we tell it the title, but it is not reflected anywhere. I'm not 100% sure why we even have the title option.
