    Stream Response

    Fetch API Response objects made from async generators. Build streaming HTML responses or SSE with JS sugar.

    Example:

    async function* generate() {
      for await (const row of iterAllRows()) {
        yield `${row.join(',')}\n`
      }
    }
    
    router.get('/large.csv', () => new StreamResponse(generate(), { 
      headers: [['content-type', 'text/csv']] 
    }))

    Creating a SSE endpoint works much the same way:

    async function* sse() {
      while (true) {
        await new Promise(r => setTimeout(r, 1000));
        yield 'data: hello\n\n';
      }
    }
    
    router.get('/sse', contentType(['text/event-stream']), (req, { type }) => {
      return new StreamResponse(sse(), { headers: [['content-type', type]] })
    })
