Stop Writing Angular HTTP Services by Hand
Short summary
Eliminate hand-written Angular HTTP service boilerplate using @constantant/openapi-resource-gen, which auto-generates type-safe, signal-native API clients from OpenAPI specs in one command. Each endpoint becomes a separate injectable token—enabling aggressive file-level tree-shaking and automatic reactive re-fetching without RxJS subscriptions, reducing bundle size and eliminating manual state management.
