Node.js stream.Writable 'pipe'事件用法及代碼示例

事件：'pipe'

參數

• src <stream.Readable> 管道傳輸到此可寫對象的源流

'pipe' 事件在可讀流上調用 stream.pipe() 方法時發出，將此可寫添加到其目標集。

const writer = getWritableStreamSomehow();
const reader = getReadableStreamSomehow();
writer.on('pipe', (src) => {
  console.log('Something is piping into the writer.');
  assert.equal(src, reader);
});
reader.pipe(writer);
