How to test performance / load of a modern angular application

I want to load / performance test a web application which uses angular 6+ as the frontend-framework. The application is quite big and uses lots of wizards / modals etc. I want to do some "real" e2e-frontend-tests (not just testing API-calls, but also js-rendering etc.)

What are the current state-of-the-art approaches and tools to test applications like this?
