使用异步生成器创建可读流

\Creating readable streams with async generators

可以使用 Readable.from() 实用程序方法从异步生成器创建 Node.js 可读流:

\A Node.js readable stream can be created from an asynchronous generator using the Readable.from() utility method:

const { Readable } = require('node:stream');
const ac = new AbortController();
const signal = ac.signal;
async function * generate() {
 yield 'a';
 await someLongRunningFn({ signal });
 yield 'b';
 yield 'c';
}
const readable = Readable.from(generate());
readable.on('close', () => {
 ac.abort();
});
readable.on('data', (chunk) => {
 console.log(chunk);
}); 拷贝
