# URL Search Param State Management

URLs that survive a refresh and a back button press

## What this does

When a page keeps some of its state in the URL, it is easy to end up with links that do not reload right or a back button that jumps somewhere unexpected. This covers that work: adding or changing the bits after the ? and the #, and sorting out browser history behaviour when it goes wrong.

### Top 3 things it does for you

- Add state to the URL query string
- Fix the back and forward buttons behaving wrongly
- Change how a page reads and writes its search params
