    The list of available props (with their types, default values and descriptions) is listed below:

    Property Required Type Default Description

    alt false string Video thumbnail Value of the alt attribute of the thumbnail <img /> element
    buttonLabel false string Play video Value of the aria-label attribute of the play <button></button> element. Improves a11y
    aspectRatio false string 16:9 Aspect ratio of the video. This prop helps to save proportions of the video on different container sizes. Should match the number:number pattern
    previewImageSize false string maxresdefault Size of the thumbnail, generated by YouTube. Available variants: default, mqdefault, sddefault, hqdefault, maxresdefault. More info
    thumbnail false { webp: string, jpg: string} Custom thumbnail object, which should contain two keys: webp and jpg. Value of the key is the path to the custom thumbnail image
    iframeAttributes false object { allowfullscreen: true, frameborder: 0, allow: 'accelerometer; autoplay; encrypted-media; gyroscope; picture-in-picture' } Custom attributes that will be assigned to the <iframe /> element
    webp false boolean true Whether or not try to load .webp thumbnail in favor of .jpg. Note that old videos may not have generated .webp thumbnail
    autoplay false boolean false Whether or not to play video as soon as component mounts into the DOM
    thumbnailListeners false Record<string, Function \| Function[]> Listeners that will be attached to the preview thumbnail
    enablejsapi false boolean false Include 'enablejapi=1' parameter to the generated src attribute of the <iframe /> element. This will allow you to listen to the init:player event as well as access the YT.Player instance via the getPlayerInstance method. Make sure you have injected the proper YouTube <script /> tag or passed the injectPlayerScript prop
    playerOptions false Partial<YT.PlayerOptions> {} Options the will be passed to the YT.Player constructor
    injectPlayerScript false boolean false Will auto inject the proper YouTube <script /> when enablejapi is passed and there is no window.YT.Player
    parameters false YT.Parameters {} YouTube Parameters that will be injected into the generated <iframe /> src attribute


    Name Payload Description
    'load:iframe' { iframe?: HTMLIFrameElement } Happens when native' <iframe /> element load event fires
    'init:player' { instance: YT.Player } Happens when the YT.Player instance is instantiated


    Name Type Description
    getPlayerInstance () => Nullable<YT.Plater> Returns an instance of the YT.Player when the enablejapi prop is passed and the YT.Player is initialized (check 'init:player' event), in other cases returns null


    Component provides some slots.

    The list of available slots is listed below:

    Slot Description
    button Slot gives an ability to provide custom play button
    icon Slot gives an ability to provide custom icon of the play button

    ⚠️ Note, that when button slot is passed and this slot contains <button></button>, ones should not to forget to add aria-label (if this button contains only icon) and type="button" attributes. Also, if that button do not contain .y-video-button class, all default styles will be lost, so style concerns it's up to developer.


    Question: How to play/pause/stop a video?

    Answer: Pass the enablejapi prop and then listen to 'init:player' event to get an instance of the YT.Player. All the available instance methods you can find here. Hint: You can also get a player instance via the getPlayerInstance method.

    import { InitPlayerEventPayload } from 'vue-lazy-youtube-video'
      // ...
        onPlayerInit(payloadInitPlayerEventPayload) {
      // ...
