The implementation code of SmartEditFeatureModule in Spartacus:
import {
NgModule } from '@angular/core';
import {
CmsConfig, provideConfig } from '@spartacus/core';
import {
SmartEditRootModule,
SMART_EDIT_FEATURE,
} from '@spartacus/smartedit/root';
@NgModule({
imports: [SmartEditRootModule],
providers: [
provideConfig(<CmsConfig>{
featureModules: {
[SMART_EDIT_FEATURE]: {
module: () =>
import('@spartacus/smartedit').then((m) => m.SmartEditModule),
},
},
}),
],
})
export class SmartEditFeatureModule {
}
Which dynamically imports @spartacus/smartedit:
The exact implementation path can be found in tsconfig.jsonthe file : feature-libs/smartedit/public_api@spartacus/smartedit
This dynamically loaded module contains the core module, not the root module. The root module is statically imported in SmartEditFeatureModule.
Also talk about the symbols @spartacus/smartedit/corein @.
In Angular projects, importit is a common practice to use the import statement of a module or library in order to use external dependencies in the code. In the code you mentioned, importthe statement imports a @spartacus/smartedit/corepackage called, where the @symbol is actually an import convention in the Node.js module system to indicate that this is an npm package (Node Package Manager package) name. Below I explain in detail what @the symbol importdoes in the statement and provide examples to illustrate its use.
@The role of the symbol :
-
Represents the scope of the npm package (Scope) : In npm, developers can create their own npm packages and publish them to the npm repository for use by other developers. In order to ensure the uniqueness of npm packages, npm introduces the concept of package scope (Scope), and
@symbols are used to represent the scope of packages. The scope of such packages is usually associated with an organization, company or project name to avoid package name conflicts. -
Simplified package management : Using
@symbols makes it easier to organize and manage related packages. It allows developers to group related packages under the same scope (Scope), which makes the code structure clearer and facilitates the release and maintenance of packages. -
Conventions and Specifications :
@A symbol as part of an npm package name is a naming convention that helps identify the source and purpose of the package. This helps maintainers and users more easily understand the meaning and purpose of the package.
Example :
Suppose there is an @myorg/my-librarynpm package called , which provides some reusable Angular components and services. To use this package in an Angular project, you can importimport it with a statement like this:
import {
MyLibraryModule } from '@myorg/my-library';
In this example, @myorg/my-libraryis the name of the package, which @myorgindicates the scope of the package (Scope). The scope of this package is usually associated with the name of the organization, company, or project that released the package. In this way, developers can easily distinguish packages from different organizations or projects and avoid package name conflicts.
In addition, if you use the Spartacus framework in the Angular project, @spartacus/smartedit/coreit is the core module provided by the Spartacus framework to support the intelligent editing function. importBy importing this module into your Angular application using the statement, you can easily leverage the power of the Spartacus framework to develop e-commerce applications.
In short, @the symbol importis used in the statement to indicate the scope of the npm package (Scope), so as to better organize and manage packages and avoid package name conflicts. This is a naming convention for npm packages that helps simplify package management, improve code readability, and facilitate package release and maintenance. In an Angular project, you can importimport @npm packages defined with symbols through statements to use external dependencies in the project.
