Building Fast WebApplications - Master Class

Building instant-on web applications at scale have been elusive. Real-world sites need tracking, analytics, and complex user interfaces and interactions. We always start with the best intentions but end up with a less-than-ideal site.

Let's look into the anatomy of a slow site and dissect it to find out how each issue got there and why fixing it is not a trivial exercise. Understanding the problem is the first step. Next is to think about possible solutions to prevent this.

Agenda:
- Anatomy of a slow site
- JavaScript over time: it is here to stay, and it is getting bigger
- JavaScript is single-threaded => CPUs cores are increasing
- Understanding the PageSpeed budget
- Third-party code
- Web-workers
- First-party code
- Hydration problem => front load JS
- Lazy loading problem => can't lazy-load visible components
- How can we have pull rather than push model of JavaScript
- Resumability is a possible solution => but it is hard
