summary
Argues that spelt compiles components at build time and ships only the code actually used, turning a typical “hello world” framework bundle of 115 KB bundle into a 2.2 KB output by removing unused features and scoping styles. Shows compiler warnings, lifecycle hooks, stores, custom element/web component support, and route-level code splitting used at Canopy to produce an admin app around 200 KB production app across eight-nine routes. Notes tradeoff: no virtual DOM or React-style time-slicing, favoring minimal runtime over framework features.
