A streaming parser for server-sent events/eventsource, without any assumptions about how the actual stream of data is retrieved. It is intended to be a building block for clients and polyfills in javascript environments such as browsers, node.js and deno....
import{EventSourceParserStream}from'eventsource-parser/stream'consteventStream=response.body.pipeThrough(newTextDecoderStream()).pipeThrough(newEventSourceParserStream()) Note that the TransformStream is exposed under a separate export (eventsource-parser/stream), in order to maximize compatibility with ...

There is also a new option to specify how parse should be handled - by default it will ignore them, but you can choose to terminate the stream or handle it manually:const stream = new EventSourceParserStream({ onError: (error: Error) => { // …handle parse error… }, }) // …...
在服务端中实现基本的流式数据响应比较方便,我们首先需要将响应头设置为text/event-stream;,注意响应头是需要在响应体之前设置的,否则在执行res.writeHead之前后执行res.write的话会导致响应ERR_INVALID_CHUNKED_ENCODING。 Copy // packages/fetch-sse/server/modules/ping.tsconstping= (req: http.IncomingMessage, ...
export class StreamParser { private onLine(bytes: Uint8Array) { if (bytes.length === 0) { if (this.onMessage && this.message.event) { this.message.data = this.message.data || ""; this.onMessage(this.message as Message); }
因此在这里我们实现StreamParser,当接收到Uint8Array二进制数据后,我们首先将其合并为新的buffer,然后遍历当前数据,当遇到n时则调度到onLine方法来处理数据。 // packages/fetch-sse/server/utils/steam-parser.ts export class StreamParser { private compose(data: Uint8Array) { const buffer = new Uint8Array(...
