Deep dive into Angular Builders
summary
Explains how Angular CLI commands like ng build and ng serve are just builders wired via package.json and angular.json, shows a 20-line command builder that shells out (demoed with ls -la and cowsay printing "builders are cool"), then a ~40-line extend builder that calls the default browser builder via createBuilder, uses context.validateOptions and observables, taps the webpack config to add the nyan-progress plugin, and notes the full default browser builder is ~820 lines.
