LaunchQueue - Web APIs | MDN
LaunchQueue Limited availability
The LaunchQueue
interface of the Launch Handler API is available via the Window.launchQueue
property. When a progressive web app (PWA) is launched with a launch_handler
client_mode
value of focus-existing
, navigate-new
, or navigate-existing
, LaunchQueue
provides access to functionality that allows custom launch navigation handling to be implemented in the PWA. This functionality is controlled by the properties of the LaunchParams
object passed into the setConsumer()
callback function.
setConsumer()
Experimental
Contains a callback function that handles custom launch navigation for a PWA.
if ("launchQueue" in window) {
window.launchQueue.setConsumer((launchParams) => {
if (launchParams.targetURL) {
const params = new URL(launchParams.targetURL).searchParams;
// Assuming a music player app that gets a track passed to it to be played
const track = params.get("track");
if (track) {
audio.src = track;
title.textContent = new URL(track).pathname.substr(1);
audio.play();
}
}
});
}
