PushMessageData.bytes() — equivalence demo

Real Push messages come from the server, but the PushMessageData interface is constructible-equivalent: any Body. Type a payload below to build a fake PushMessageData-shaped object and inspect what bytes() returns, side-by-side with the old arrayBuffer() + new Uint8Array() pattern.

checking support…

response.bytes() — new

—

arrayBuffer() → Uint8Array — old

service worker shape

self.addEventListener("push", e => {
  const u8 = e.data.bytes();          // Uint8Array
  const json = JSON.parse(new TextDecoder().decode(u8));
});
