Uncaught ReferenceError: BroadcastChannel is not defined

Question

尝试在本地 运行 deno 支持 broadcast channel 的 deno 部署应用程序，但出现此编译错误我该如何解决？

const channel = new BroadcastChannel('')

Uncaught ReferenceError: BroadcastChannel is not defined

Answer 1

它在 v1.17.1 的稳定文档中，所以不需要 --unstable 来使用它：

https://doc.deno.land/deno/stable@v1.17.1/~/BroadcastChannel

Compare with unstable: https://doc.deno.land/deno/unstable@v1.17.1

然而，实际上并非如此：

$ deno
Deno 1.17.1
exit using ctrl+d or close()
> new BroadcastChannel()
Uncaught ReferenceError: BroadcastChannel is not defined
    at <anonymous>:2:1
> close()
$ deno --unstable
Deno 1.17.1
exit using ctrl+d or close()
> new BroadcastChannel()
Uncaught TypeError: Failed to construct 'BroadcastChannel': 1 argument required, but only 0 present.
