Angular module
An Angular module is an NgModule-based application unit that groups and configures declarations, imports, providers, and exports.
Pro Angular 16
A feature module is an Angular module that groups the components, services, and dependencies associated with a particular application feature.
- How it is used
- Groups related functionality into manageable units while the root module configures the application as a whole.
- How deep it goes
- Works through service, utility, component, and on-demand modules, including decorator properties, exports, root imports, and a provider-scope pitfall.
- Examples
- Uses a service-only data-model module, a shared utility module, a component module, and an on-demand administration module.
- What you can do after
- Build it from scratch by grouping related features, registering dependencies and services, exposing selected components, and importing the module where needed.
Modern Angular
An NgModule is an Angular mechanism for grouping declarations, imports, providers, and exports into a module-based application unit.
- How it is used
- Organizes declarations, imports, providers, exports, and bootstrap in legacy module-based Angular applications.
- How deep it goes
- Explains NgModule wiring and dependency indirection, then gives manual, SCAM-assisted, and schematic migration procedures.
- Examples
- Uses AppModule bootstrap code and an HRMS employee-list and employee-tile feature module.
- What you can do after
- Operate/configure an incremental migration from NgModules to standalone APIs, including the Angular v16 schematic workflow.
