TransformStream 現在支援跨瀏覽器
透過集合功能整理內容
你可以依據偏好儲存及分類內容。
現在已支援 Chrome、Safari 和 Firefox 轉換串流,這些轉換串流終於可及時了!
Streams API 可讓您將想要接收、傳送或轉換的資源細分為小區塊,然後逐一處理這些區塊。最近,Firefox 102
開始支援 TransformStream
,
這表示 TransformStream
還能在不同瀏覽器上使用轉換串流可讓您從
將 ReadableStream
轉換為
WritableStream
,執行
或是直接取用轉換後的結果
如以下範例所示
class UpperCaseTransformStream {
constructor() {
return new TransformStream({
transform(chunk, controller) {
controller.enqueue(chunk.toUpperCase());
},
});
}
}
button.addEventListener('click', async () => {
const response = await fetch('/script.js');
const readableStream = response.body
.pipeThrough(new TextDecoderStream())
.pipeThrough(new UpperCaseTransformStream());
const reader = readableStream.getReader();
pre.textContent = '';
while (true) {
const { done, value } = await reader.read();
if (done) {
break;
}
pre.textContent += value;
}
});
