Wizard

This component can be found under the Sybrin.Document namespace and is called WizardComponent.

Full name: Sybrin.Document.WizardComponent.

It is a component that wraps and orchestrates the rest of the document capture components.

As the user interacts with components housed within the wizard component, it will automatically progress and keep track of steps.

Initialization

The wizard component can be initialized using the following code:

HTML

<div id='wizard'></div>

JavaScript

var options = new Sybrin.Document.Options({
    // Set up API configuration here
});

// Option 1: Providing an id
var component = new Sybrin.Document.WizardComponent({ 
    id: 'wizard',
    options: options
});

// Option 2: Providing a DOM element
var element = document.getElementById('wizard');
var component = new Sybrin.Document.WizardComponent({ 
    element: element,
    options: options
});

component.initialize();

The Sybrin Web SDK provides the option to either provide the ID of the element you wish to use for component initialization, or to provide the element directly.

Please note that 'wizard' is just an example in this context and the ID may be changed as desired as long as it matches the value provided during component initialization in JavaScript.

During initialization, the wizard component allows for a number of configuration options that may be provided using an object literal. The parameters that may be used on the object include the following:

Required:

• id (string): ID of the element you wish to use for component initialization. Not required if element is provided.

• element (HTMLElement): Element you wish to use for component initialization. Not required if id is provided.

• api (Sybrin.Document.Api): Instance of a JavaScript API that may be pre-configured as desired. Not required if an instance of options is passed.

• options (Sybrin.Document.Options): Configuration options to instantiate Sybrin.Document.Api with. Not required if an instance of api is passed.

Optional:

• cameraDirectionPriority (number): This property is used to determine which camera direction the SDK should try to prioritize. 0 is none, meaning it will always prompt device selection. 1 is front, meaning it will default to the front camera if only one front device is found. 2 is back, meaning it will default to the rear camera if only one rear device is found.

• correlationId: Sets the correlation ID for the case that will be provided with the OCR request. Used for advanced tracking and backend data sync.

• countries (Sybrin.Document.Country[]): Explicit country filter to be used by the country select component. Please see country overrides & filtering for details.

• cropSelectionStart (Sybrin.Document.CropSelectionStart): Sets how the crop selection area should be initialized. The options are middle (0) and full (1). The middle option sets the crop selection area to start as a smaller block in the center of the image. The full option will initially select the entire image.

• defaultDocumentType (string): The type of document that must be selected by default.

• defaultCountry (string): The country code of the country that must be selected on the Country Select component by default.

• documentTypes (Sybrin.Document.DocumentType[]): Explicit document type filter to be used by the document select component. Please see document type overrides & filtering for details.

• enableOcr (boolean): Sets whether or not OCR must be executed by the Result component.

• imageCaptureFormat (string: 'jpeg' | 'png'): Sets the format that the images will be captured in. Defaults to JPEG.

• imageUploadFormat (string: 'original' | 'jpeg'): Sets the format that images will be converted to for upload. Defaults to original.

• initialImages (string[]): Sets the initial collection of images to be processed. This is useful if the SDK is being used as a standalone component for image cropping, rotation, and other processing purposes.

• processComponentHideBack (boolean): Sets whether or not the back button must be hidden on the document processing component. Default false.

• readonlyMode (boolean): Disables all events if true. Default false.

• steps (string): A collection of strings to specify/override the steps that the wizard should display, as well as their order. The string values may be:

  • 'country-select' to specify the country select component.

  • 'document-select' to specify the document select component.

  • 'prepare' to specify the prepare component.

  • 'device-select' to specify the device select component.

  • 'document-capture' to specify the document capture component.

  • 'document-processing' to specify the document processing component.

  • 'result' to specify the result component.

• selectedDocumentTypeName (string): The default document type name code to use if the document select component is excluded as a step in the wizard component.

• selectedDocumentTypeId (string): The default ID that points to a unique document type for a specific country if both the country select component and the document select component are excluded as a step in the wizard component. Can be used as a singular alternative to providing selectedCountryCode and selectedDocumentTypeName.

• selectedCountryCode (string): The default country code to use if the country select component is excluded as a step in the wizard component.

• translations ({ [key: string]: string }): An object literal representing a dictionary lookup that will be used for translating the component. Please see the translations section on this page for a list of all translatable text, as well as the localization page for a detailed description on how to implement localization.

Warning: Initialization will fail if the intended host element does not exist yet.

Always ensure that the initialize function is only called after the DOM is loaded.

Destruction

The wizard component may be removed from the UI by calling the destroy() function on it.

Example:

component.destroy();

Functions

Initialize

initialize(): Promise<void>

Initializes the component's DOM and events. The initialization function is asynchronous.

Destroy

destroy(): void

Destroys the component's DOM and events.

Set Correlation ID

setCorrelationId(correlationId: string): void

Sets the correlation ID to the provided value.

Set Translations

setTranslations(translations?: { [key: string]: string; }): void

Changes the component's translations to the provided values and updates the DOM accordingly.

Get Current Step

getCurrentStep(): StepType

Gets the step that is currently active in the wizard. StepType is:

"country-select" | "document-select" | "prepare" | "device-select" | "document-capture" | "document-processing" | "result";

Back

back(): void

Signals to the wizard to revert to the previous step.

Next

next(): void

Signals to the wizard to proceed to the next step.

Events

The wizard component offers multiple events. To hook onto an event, simply assign a function to it.

The following options are available:

component.onBeforeStepChanged = function(oldStep, newStep) {
    console.log('The old step is: ', oldStep);
    console.log('The new step will be: ', newStep);
}

The oldStep parameter is of type string.

The newStep parameter is of type string.

    console.log('The old step was: ', oldStep);
    console.log('The new step is: ', newStep);
}

The oldStep parameter is of type string.

The newStep parameter is of type string.

On Country Selected

This event bubbles the onCountrySelected event up once it executes on the country select component.

On Document Selected

This event bubbles the onDocumentSelected event up once it executes on the document select component.

On Capture Result

This event bubbles the onCaptureResult event up once it executes on the document capture component.

On Capture Error

This event bubbles the onCaptureError event up once it executes on the document capture component.

On Capture Cancelled

On Before Capture

This event bubbles the onBeforeCapture event up once it executes on the document capture component.

On Before Upload

This event bubbles the onBeforeUpload event up once it executes on the prepare component.

On View Privacy Policy

This event bubbles the onViewPrivacyPolicy event up once it executes on the prepare component.

Styling

The wizard component is structured a follows:

<div class="sybrin-document-wizard sybrin-sdk-wizard">
    <div class="sybrin-document-wizard-viewport sybrin-sdk-wizard-viewport">
    </div>
</div>

Since the wizard component has no visual elements by itself, no styling is necessary. Please style individual components housed within the wizard instead.

Translations

The translations provided to this component are in turn provided to the internal components hosted by it. Please see individual component translation sections for details on which translation keys are available to them, and also the localization section for an overview on available keys and how to make use of localization functionality.
