#342 - introduce standalone flag

[mumenthalers]

closes #342

changes:

• standalone option added
• prevent module being generated when standalone is set
• generate and export provideApiConfiguration (accepting value or factory)

Will this work in case of multiple schemas? I for example have 2 BE services (schemas) and I have to generate 2 different configs, which generate 2 different modules.

Example: ChatApiModule and UserApiModule

Which i then import:

importProvidersFrom([
    UserApiModule.forRoot({ rootUrl: USER_SERVICE_ENDPOINT_PREFIX }),
    ChatApiModule.forRoot({ rootUrl: CHAT_SERVICE_ENDPOINT_PREFIX }),
]),

Will your solution work in this use case?

yes - it works the same way as module (which defaults to ApiModule).
You need to provide a custom name for the configurationClass

{
  "$schema": "../node_modules/ng-openapi-gen/ng-openapi-gen-schema.json",
  "input": "user-api.yaml",
  "module": false,
  "configuration": "UserApiConfiguration"
}

{
  "$schema": "../node_modules/ng-openapi-gen/ng-openapi-gen-schema.json",
  "input": "chat-api.yaml",
  "module": false,
  "configuration": "ChatApiConfiguration"
}

then you can use it like

bootstrapApplication(AppComponent, {
  providers: [
    provideUserApiConfiguration({ rootUrl: USER_SERVICE_ENDPOINT_PREFIX }),
    provideChatApiConfiguration({ rootUrl: CHAT_SERVICE_ENDPOINT_PREFIX }),
  ]
})
