Schematics

Spartacus schematics allow you to install Spartacus libraries in your project. The following sections describe what the Spartacus schematics do, and also provide information about the various options and commands you can use with the schematics. If you are a developer and are looking for more technical information, see the README in the Spartacus schematics project.

Prerequisites

Before using Spartacus schematics, ensure that the following requirements are met:

  • Your Angular CLI is on version 9.1 or higher
  • Your application is using Angular 9 or higher
  • Your Node version is less than or equal to version 13.

Adding Spartacus Libraries to Your Angular Project

You can add Spartacus libraries to your Angular project by running the following command from your project root:

ng add @spartacus/schematics

The following is a description of the various options you can use with the ng add @spartacus/schematics command:

  • baseUrl sets the base URL of your CX OCC back end.
  • baseSite is a comma-separated list of base site(s) to use with Spartacus.
  • currency is a comma-separated list of currencies to use in Spartacus.
  • language is a comma-separated list of languages to use in Spartacus.
  • occPrefix sets the OCC API prefix, such as /occ/v2/, for example.
  • useMetaTags determines whether or not to configure the baseUrl and mediaUrl in the meta tags from index.html.
  • featureLevel sets the application feature level. The default value is 2.0.
  • overwriteAppComponent overwrites the content of app.component.html. The default value is true.
  • pwa includes progressive web application (PWA) features when building the application.
  • ssr includes the server-side rendering (SSR) configuration.

The following is an example that generates an application that is ready to be used with the electronics storefront, that sets the baseUrl and the baseSite, and that also enables server-side rendering:

ng add @spartacus/schematics --baseUrl https://api.c39j2-walkersde1-d4-public.model-t.cc.commerce.ondemand.com/ --baseSite=electronics-spa --ssr

Another example is the following, which generates an application that is ready to be used with both an apparel storefront and an electronics storefront, that sets the baseUrl, baseSite, currency, and language, and also enables server-side rendering:

ng add @spartacus/schematics --baseUrl https://api.c39j2-walkersde1-d4-public.model-t.cc.commerce.ondemand.com/ --baseSite=apparel-uk-spa,electronics-spa --currency=gbp,usd --language=uk,en --ssr

Additional Commands

By default, the ng add @spartacus/schematics command adds only a basic configuration of Spartacus. The following is a description of the commands you can use to extend your application:

  • ng g @spartacus/schematics:add-pwa adds a Spartacus-specific PWA module.
  • ng g @spartacus/schematics:add-ssr adds the SSR configuration.
  • ng g @spartacus/schematics:add-cms-component generates a CMS component, and adds the CMS component mapping to the specified module, or to a newly-generated module, if no module is specified. For more information, see CMS Component Schematic, below.

How Spartacus Schematics Work

When you run ng add @spartacus/schematics, the command does the following:

  1. Adds the required dependencies.
  2. Imports the Spartacus modules in the app.module and sets up the default configuration.
  3. Imports Spartacus styles to main.scss.
  4. Adds the cx-storefront component to your app.component.
  5. Optionally updates index.html with the Spartacus URL endpoints in meta tags.
  6. If the --pwa flag is included, it adds PWA service worker support for your project.
  7. If the --ssr flag is included, the command does the following:
    • Adds server-side rendering dependencies.
    • Provides additional files that are required for SSR.

CMS Component Schematic

The following is a description of the available options for the CMS component schematic:

  • --declareCmsModule specifies which module the newly-generated CMS component is added to. If no module is specified, a new module is generated.
  • --cmsComponentData, alias --cms, injects the CmsComponentData into the new component. By default, this option is set to true.
  • --cmsComponentDataModel, alias --cms-model, specifies the model class for the CmsComponentData, such as MyModel, for example. This argument is required if --cmsComponentData is set to true.
  • --cmsComponentDataModelPath, alias --cms-model-path, specifies the import path for the CmsComponentData. The default is @spartacus/core.

Aside from these custom options, the add-cms-component supports almost all options that are available for the Angular component and module schematics. The full list can be seen in this schema.json file.

The following Angular options are not supported:

  • Deprecated options.
  • The --module option for components. If you want to specify an existing module for a component, use --declareCmsModule. The module option is only applied to the Angular module schematic.
  • The --skipImport option.

Using the ‘add-cms-component’ Schematic

The following are some examples of how the add-cms-component schematic can be used:

  • ng g @spartacus/schematics:add-cms-component myAwesomeCms --cms-model=MyModel generates the my-awesome-cms.component.ts component and the my-awesome-cms.module.ts module.
  • ng g @spartacus/schematics:add-cms-component myAwesomeCms --cms-model=MyModel --declareCmsModule=my-cms-path/my-cms generates the my-awesome-cms.component.ts component and adds it to the specified CMS mapping for my-cms-path/my-cms.module.ts.
  • ng g @spartacus/schematics:add-cms-component myAwesomeCms --cms-model=MyModel --module=app generates the my-awesome-cms.component.ts component and the my-awesome-cms.module.ts module, and imports them to the specified app.module.ts.
  • ng g @spartacus/schematics:add-cms-component myAwesomeCms --cms-model=MyModel --module=app --declareCmsModule=my-cms-path/my-cms generates the my-awesome-cms.component.ts component and adds it to the specified my-cms-path/my-cms.module.ts module. It also imports my-cms.module.ts to the specified app.module.ts.
