Luigi Client API

Lifecycle

Use the functions and parameters to define the Lifecycle of listeners, navigation nodes, and Event data.

addInitListener

Registers a listener called with the context object and the Luigi Core domain as soon as Luigi is instantiated. Defer your application bootstrap if you depend on authentication data coming from Luigi.

Parameters

removeInitListener

Removes an init listener.

Parameters

  • id string the id that was returned by the addInitListener function

addContextUpdateListener

Registers a listener called with the context object upon any navigation change.

Parameters

  • contextUpdatedFn function the listener function called each time Luigi context changes

removeContextUpdateListener

Removes a context update listener.

Parameters

  • id string the id that was returned by the addContextUpdateListener function

addCustomMessageListener

Registers a listener called when the micro frontend receives a custom message.

Parameters

Meta

  • since: 0.6.2

removeCustomMessageListener

Removes a custom message listener.

Parameters

  • id string the id that was returned by the addInitListener function

Meta

  • since: 0.6.2

getToken

Returns the currently valid access token.

Returns string current access token

getEventData

Returns the context object. Typically it is not required as the addContextUpdateListener() receives the same values.

Returns Object current context data

getContext

Returns the context object. It is an alias function for getEventData().

Returns Object current context data

getNodeParams

Returns the node parameters of the active URL. Node parameters are defined like URL query parameters but with a specific prefix allowing Luigi to pass them to the micro frontend view. The default prefix is ~ and you can use it in the following way: https://my.luigi.app/home/products?~sort=asc~page=3.

NOTE: some special characters (<, >, ", ', /) in node parameters are HTML-encoded.

Returns Object node parameters, where the object property name is the node parameter name without the prefix, and its value is the value of the node parameter. For example {sort: 'asc', page: 3}

getPathParams

Returns the dynamic path parameters of the active URL. Path parameters are defined by navigation nodes with a dynamic pathSegment value starting with :, such as productId. All path parameters in the current navigation path (as defined by the active URL) are returned.

NOTE: some special characters (<, >, ", ', /) in path parameters are HTML-encoded.

Returns Object path parameters, where the object property name is the path parameter name without the prefix, and its value is the actual value of the path parameter. For example {productId: 1234, ...}

getClientPermissions

Returns the current client permissions as specified in the navigation node or an empty object. For details, see Node parameters.

Returns Object client permissions as specified in the navigation node.

sendCustomMessage

Sends a custom message to the Luigi Core application.

Parameters

  • message Object an object containing data to be sent to the Luigi Core to process it further. This object is set as an input parameter of the custom message listener on the Luigi Core side.
    • message.id string a string containing the message id
    • message.MY_DATA_FIELD any any other message data field

Examples

import LuigiClient from '@kyma-project/luigi-client';
LuigiClient.sendCustomMessage({id: 'environment.created', production: false})

Meta

  • since: 0.6.2

Lifecycle~initListenerCallback

Callback of the addInitListener

Type: Function

Parameters

  • context Object current context data
  • origin string Luigi Core URL

Lifecycle~customMessageListenerCallback

Callback of the customMessageListener

Type: Function

Parameters

  • customMessage Object custom message object
    • customMessage.id string message id
    • customMessage.MY_DATA_FIELD any any other message data field
  • listenerId string custom message listener id to be used for unsubscription

linkManager

The Link Manager allows you to navigate to another route. Use it instead of an internal router to:

  • Provide routing inside micro frontends.
  • Reflect the route.
  • Keep the navigation state in Luigi.

navigate

Navigates to the given path in the application hosted by Luigi. It contains either a full absolute path or a relative path without a leading slash that uses the active route as a base. This is the standard navigation.

Parameters

  • path string path to be navigated to
  • sessionId string current Luigi sessionId
  • preserveView boolean preserve a view by setting it to true. It keeps the current view opened in the background and opens the new route in a new frame. Use the goBack() function to navigate back. You can use this feature across different levels. Preserved views are discarded as soon as you use the standard navigate() function instead of goBack()
  • modalSettings Object opens a view in a modal. Use these settings to configure the modal's title and size
    • modalSettings.title string modal title. By default, it is the node label. If there is no label, it is left empty
    • modalSettings.size ("l" | "m" | "s") size of the modal (optional, default "l")
  • splitViewSettings Object opens a view in a split view. Use these settings to configure the split view's behaviour
    • splitViewSettings.title string split view title. By default, it is the node label. If there is no label, it is left empty
    • splitViewSettings.size number height of the split view in percent (optional, default 40)
    • splitViewSettings.collapsed boolean creates split view but leaves it closed initially (optional, default false)

Examples

LuigiClient.linkManager().navigate('/overview')
LuigiClient.linkManager().navigate('users/groups/stakeholders')
LuigiClient.linkManager().navigate('/settings', null, true) // preserve view

openAsModal

Opens a view in a modal. You can specify the modal's title and size. If you don't specify the title, it is the node label. If there is no node label, the title remains empty. The default size of the modal is l, which means 80%. You can also use m (60%) and s (40%) to set the modal size. Optionally, use it in combination with any of the navigation functions.

Parameters

  • path string navigation path
  • modalSettings Object? opens a view in a modal. Use these settings to configure the modal's title and size
    • modalSettings.title string modal title. By default, it is the node label. If there is no label, it is left empty
    • modalSettings.size ("l" | "m" | "s") size of the modal (optional, default "l")

Examples

LuigiClient.linkManager().openAsModal('projects/pr1/users', {title:'Users', size:'m'});

openAsSplitView

  • See: splitView for further documentation about the returned instance

Opens a view in a split view. You can specify the split view's title and size. If you don't specify the title, it is the node label. If there is no node label, the title remains empty. The default size of the split view is 40, which means 40% height of the split view.

Parameters

  • path string navigation path
  • splitViewSettings Object opens a view in a split view. Use these settings to configure the split view's behaviour (optional, default {})
    • splitViewSettings.title string split view title. By default, it is the node label. If there is no label, it is left empty
    • splitViewSettings.size number height of the split view in percent (optional, default 40)
    • splitViewSettings.collapsed boolean opens split view in collapsed state (optional, default false)

Examples

const splitViewHandle = LuigiClient.linkManager().openAsSplitView('projects/pr1/logs', {title: 'Logs', size: 40, collapsed: true});

Returns Object instance of the SplitView. It provides Event listeners and you can use the available functions to control its behavior.

Meta

  • since: 0.6.0

fromContext

Sets the current navigation context to that of a specific parent node which has the navigationContext field declared in the navigation configuration. This navigation context is then used by the navigate function.

Parameters

Examples

LuigiClient.linkManager().fromContext('project').navigate('/settings')

Returns linkManager link manager instance

fromClosestContext

Sets the current navigation context which is then used by the navigate function. This has to be a parent navigation context, it is not possible to use the child navigation contexts.

Examples

LuigiClient.linkManager().fromClosestContext().navigate('/users/groups/stakeholders')

Returns linkManager link manager instance

withParams

Sends node parameters to the route. The parameters are used by the navigate function. Use it optionally in combination with any of the navigation functions and receive it as part of the context object in Luigi Client.

Parameters

Examples

LuigiClient.linkManager().withParams({foo: "bar"}).navigate("path")

// Can be chained with context setting functions such as:
LuigiClient.linkManager().fromContext("currentTeam").withParams({foo: "bar"}).navigate("path")

Returns linkManager link manager instance

pathExists

Checks if the path you can navigate to exists in the main application. For example, you can use this helper method conditionally to display a DOM element like a button.

Parameters

  • path string path which existence you want to check

Examples

let pathExists;
 LuigiClient
 .linkManager()
 .pathExists('projects/pr2')
 .then(
   (pathExists) => {  }
 );

Returns promise a promise which resolves to a Boolean variable specifying whether the path exists or not

hasBack

Checks if there is one or more preserved views. You can use it to show a back button.

Returns boolean indicating if there is a preserved view you can return to

goBack

Discards the active view and navigates back to the last visited view. Works with preserved views, and also acts as the substitute of the browser back button. goBackContext is only available when using preserved views.

Parameters

  • goBackValue any data that is passed in the goBackContext field to the last visited view when using preserved views.

Examples

LuigiClient.linkManager().goBack({ foo: 'bar' });
LuigiClient.linkManager().goBack(true);

splitView

Split view Allows to open a micro frontend in a split screen in the lower part of the content area. Open it by calling const splitViewHandle = LuigiClient.linkManager().openAsSplitView. At a given time, you can open only one split view. It closes automatically when you navigate to a different route. When you call handle.collapse(), the split view gets destroyed. It recreates when you use handle.expand(). openAsSplitView returns an instance of the split view handle. The functions, actions, and event handlers listed below allow you to control and manage the split view.
