It's awesome, I'm currently building an e-commerce website using Algolia + InstantSearch, it's great to have an example with Typesense I really felt like it was missing.

Would it be easy to add filters that appear only for the relevant items? For example if there were phones and speakers, both would have a battery capacity but only phones would have a screen size. And would it be made with the front-end or could it be done using Typesense? I'm looking into implementing a classification system into the website for this kind of purpose.

You can do this yes, but if you want to implement it without a page refresh or creating a new page (where you'd instantiate the required filters based on the page), then you'd have to create a new custom widget in Instantsearch, that looks at the results for a particular query and then based on the attributes returned in the results, the widget would have to issue a new call to Typesense this time with facet_by set to those fields and then render widgets for the facetted attributes returned.

Looks like Algolia has put together a guide on how to do this with Instantsearch: https://github.com/algolia/dynamic-faceting-instant-search-guide
