General Concepts

The inline edit APIs define how an application can register DOM elements to be inline editable and also an API how an implementor of inline edit functionality can hook into the system. The purpose of the consumer facing interface WchInlineEditServiceV2 is to make it convenient to use the service, the purpose of the provider facing interface WchInlineEditProviderV2 to implement the service. The glue layer between both is a generic implementation by the SDK.

Refer to the framework specific modules to learn how to access the services.

Provider

The edit provider is a piece of javascript code that implements inline edit functionality. It is dynamically loaded by the SPA (typically via the SDK). The provider needs to conform to the following pattern:

Initialization

The edit module implements the WchInlineEditProviderV2 interface, i.e. it exposes a register function. This function will be invoked for each editable HTML element and allows the edit provider to attach the desired edit hooks to the elements. The method is provided with:

• a reference to the actual HTML element
• an accessor expression that identifies the element on a content item to be edited. This expression is relative to the current rendering context
• a reactive stream of rendering contexts. Note that the rendering contexts can change during the lifetime of this registration. Also there is no guarantee that the element pointed to by the accessor actually exists on the context. If a provider subscribes to the sequence of rendering contexts, it needs to make sure to NOT throw an exception in the subscribe block under any circumstances

Result

The result of a registration is an event provider. The purpose of this provider is to communicate inline edit operations on the HTML element to the host, i.e. the host registers for events on that event provider and the edit provider is responsible to firing these events (if the event is supported).

The event provider can optionally implement the Disposable interface. If implemented the host will call its dispose method after registration, before the HTML element gets removed from the DOM (so it's the inverse operation to the registration call).

Notifications

The implementor of the WchInlineEditProviderV2 MAY optionally also implement the EventTargetLike interface, i.e. be an event emitter. This allows the provider to communicate information to the SDK, e.g. about enabled or disabled inline edit mode.

Currently supported notifications are:

• wchInlineEditStart to notify about entering inline edit mode
• wchInlineEditEnd to notify about leaving inline edit mode

WchInlineEditService

The WchInlineEditServiceV2 interface allows a client to interact with the inline edit implementation. The implementation of this interface makes sure to load the inline edit provider and to fulfill the interface contract with the provider.

A consumer of this interface calls the registerComponent message for each HTML element that is supposed to be edited. The result of this call is an Observable. The inline edit registration begins as soon as someone subscribes to this observable and ends as soon as this subscription ends. It is in the responsibility of the consumer to make sure that the HTML element exists for the duration of the subscription.
