Original: Part 2: Angular Bundle Size Is Only One Part of Performance
Short summary
This article argues that Angular bundle size is only one dimension of frontend performance, separating loading performance from runtime performance. It covers lazy-loaded routes, third-party dependency management, and the full pipeline from download to user interaction. The author illustrates how two applications with identical bundle sizes can have very different user experiences due to initialization work.
- •Bundle size optimization improves load time but not necessarily runtime performance
- •Covers lazy loading routes and managing third-party dependencies
- •Explains the full performance pipeline: download, parse, execute, bootstrap, render, interact
