Deep Dive Into CLI Builders
summary
Explains that Angular CLI actions are implemented as builders and shows two concrete builders: a 20–30 line command builder that spawns child processes (demo runs ls and a calc tool) and an extend builder that wraps the default browser builder, calls devkit APIs (targetFromTargetString, context.getTargetOptions, validateOptions), injects a webpack plugin (Nyan progress) and produces the nyan-cat output; notes the real browser builder is ~820 lines of code.
