To keep the list filtered after a reload you can use the history api, namely the history.pushState

It is as simple as:

history.pushState(null, ‘’, theUrlYouWantItToBe);

const search = '?filter=["wine","milk"]';history.pushState(null, ‘’, location.origin + search);

To easily serve a local file you can use http-server

npm install http-server -g

Create an index.html file with the code from the snippet. In the folder serve the file with the following command

http-server

And boom! 💥
