Describe the bug
It looks like it is expected behaviour but I don't think we should allow an empty input call from the frontend.

To Reproduce

Don't type anything in the search box and press enter.

It takes you to https://bundlephobia.com/package which gives 404.

Expected behavior
I believe we should just do nothing when the input is empty.

Let me know if the suggested fix is good and I can make a relevant PR for the same.
