  • These modules contain 3 things: – /shared: services and interfaces,/pages: routed components,/components: pure presentation components.Shared services forpagesTo display a page, you need data first.
  • But be sure your services for pages are specific to the module, because if you opt for lazy-loading, they will just be available in this particular module (which is good), and not elsewhere in app.
  • ReusabilityModules of global services are reusable through different projects if you take care to have no specific dependency in them (no UI or app specific code), and if you separate each features in different modules (do not put every service in just one big global module).
  • SummaryExample of a module of reusable UI components: – ConclusionIf you follow those steps: – youll have a consistent architecture: in small or big apps, with or without lazy-loading,your modules of global services and your modules of reusable components are ready to be packaged as libraries, reusable in other projects,youll…
