    Vue.use(incognitus, {
      tenantId: '{your tenant key}',

    import { incognitus } from '@incognitus/client-vue';

        tenantId: '{your tenant key}',
        applicationId: '{your app id}',
    Key Description
    tenantId Your tenant id
    applicationId The id of the application and environment

    Checking features


    You can use the included component to check feature flags. This is transparent and will not add an extra depth in the DOM. Using slots, you can configure different aspects like the loading state, or if the flag is enabled/disabled.

      <feature-flag flag="feature name">
        <template #loading> Checking features </template>
        <template #enabled> Something behind the flag </template>
        <template #disabled> The old implementation </template>


    Prop Description
    flag The name of the feature flag
    hidden Hide content when the flag is enabled


    Slot Description
    loading Displayed when fetching the feature flag
    enabled Rendered when the flag is enabled
    disabled Rendered when the flag is disabled

    Composition API hook

    If you would like to interact with the service directly, then it can be accessed through the useIncognitus hook. This returns isReady which returns true when the service is initiatlized and ready to be used, and service which returns the raw service

    Service methods

    Method Description
    service.isEnabled(featureName) Checks if the flag is enabled
    service.isDisabled(featureName) Check if the flag is disabled
    service.getFeature(featureName) Fetches the feature from the server and returns it's status
    service.getAllFeatures() Fetches all features and stores them in the cache


    You can also use the service directly by importing IncognitusService.instance, however this is not recommended.


    Currently all known feature flags are cached when the app initializes. New features that are not found in the cache are retrieved on-demand. The cache stays in place until the app is reloaded or by calling the getAllFeatures() method on the service.
