Web service client - ways to make it

I have REST web service written using Spring Boot. Now I want to write www site which will be using this Web service. How should I write this client? I've been thinking about writing it using JavaScript to handle http requests and all stuff, but after searching for it in Google I'm confused and I don't know what to do. I've also thought about preparing data in Web service and just showing it in static HTML page. Which way is better? And why? Which technologies should I check?
