Halaman ini menjelaskan cara mengirim pesan di sisi klien dari add-on yang berjalan di iframe panel samping ke add-on yang berjalan di iframe tahap
utama. Pengiriman pesan frame-ke-frame hanya terjadi di sisi klien, sehingga pengiriman pesan hampir instan.
Untuk mengirim pesan:
Dari panel samping ke panggung utama, gunakan metode
notifyMainStage().
Panjang payload
harus sesuai dengan batas ukuran yang ditentukan.
Untuk menerima pesan, add-on harus berlangganan ke callback
frameToFrameMessage. Contoh kode berikut menunjukkan cara berlangganan callback frameToFrameMessage:
Pesan frame-ke-frame yang dikirim oleh peserta tertentu hanya dapat dilihat oleh
peserta yang sama. Untuk mengirim pesan atau status ke peserta lain, pelajari cara membagikan status add-on.
Pengiriman pesan hanya dicoba satu kali. Untuk menerima pesan, panel penerima harus terbuka dan aplikasi harus berlangganan ke callback sebelum pesan dikirim.

Frame-to-frame\nmessaging only occurs on the client side, so message delivery is near\ninstantaneous.\n\nTo send a message:\n\n- From the side panel to the main stage, use the [`notifyMainStage()`](/workspace/meet/add-ons/reference/websdk/addon_sdk.meetsidepanelclient.notifymainstage) method.\n\n await sidePanelClient.notifyMainStage(\"\u003cvar translate=\"no\"\u003eYOUR_MESSAGE\u003c/var\u003e\");\n\n- From the main stage to the side panel, use the [`notifySidePanel()`](/workspace/meet/add-ons/reference/websdk/addon_sdk.meetmainstageclient.notifysidepanel) method.\n\n await mainStageClient.notifySidePanel(\"\u003cvar translate=\"no\"\u003eYOUR_MESSAGE\u003c/var\u003e\");\n\nThe [`payload`](/workspace/meet/add-ons/reference/websdk/addon_sdk.frametoframemessage.payload)\nlength must conform to its specified size limit.\n\nTo receive the message, the add-on must subscribe to\nthe\n[`frameToFrameMessage`](/workspace/meet/add-ons/reference/websdk/addon_sdk.addoncallbacks.frametoframemessage)\ncallback. The following code sample shows how to subscribe to a\n`frameToFrameMessage` callback: \n\n sidePanelClient.on('frameToFrameMessage', (arg: FrameToFrameMessage) =\u003e {\n // YOUR_CODE\n });\n\nThe [\"Animation\" sample add-on on GitHub](https://github.com/googleworkspace/meet/tree/3311b735550b8927c8b7ef2c6d06f768d9fe0476/addons-web-sdk/samples/animation-next-js)\nincludes a full example of frame-to-frame messaging. After the activity starts,\nthe side panel [notifies the main stage whenever the user changes an input](https://github.com/googleworkspace/meet/blob/3311b735550b8927c8b7ef2c6d06f768d9fe0476/addons-web-sdk/samples/animation-next-js/src/app/activitysidepanel/page.tsx#L27).\nThe main stage also [subscribes to the `frameToFrameMessage` callback](https://github.com/googleworkspace/meet/blob/3311b735550b8927c8b7ef2c6d06f768d9fe0476/addons-web-sdk/samples/animation-next-js/src/app/mainstage/page.tsx#L43)\nto receive updated state.\n\nNotes\n-----\n\n- Frame-to-frame messages sent by a given participant are *only* visible by\n that same participant. To send messages or state to other participants,\n learn how to [share add-on\n state](/workspace/meet/add-ons/guides/collaborate-in-the-add-on#collaboration).\n\n- Message delivery is only attempted once. To receive messages, the receiving\n panel must be open and the app must subscribe to the callback before the\n message is sent.\n\nRelated topics\n--------------\n\n- [Implement the Co-Doing API](/workspace/meet/add-ons/guides/use-CoDoingAPI)"]]
