There is support for websockets if that is what you are looking for: https://adonisjs.com/docs/4.1/websocket |

Yes, I've tried adding them but I could not get it to work. I've tried to implement a simple countdown as a test. Here is the code from my import Route from '@ioc:Adonis/Core/Route'
import { ResponseContract } from '@ioc:Adonis/Core/Response'
Route.on('/').render('index')
function countdown(response: ResponseContract, count: number) {
console.log(`Countdown: ${count}`)
response.send(`data: ${count}\n\n`)
if (count) {
return new Promise((resolve) => {
setTimeout(() => resolve(countdown(response, count - 1)), 1000)
})
}
}
Route.get('/countdown', async ({ response }) => {
response.header('content-type', 'text/event-stream')
response.header('cache-control', 'no-cache')
response.header('connection', 'keep-alive')
//response.flushHeaders(200)
await countdown(response, 10)
})And here is the code for my <!DOCTYPE html>

const eventSource = new EventSource('/countdown')
const dataList = document.querySelector('#data')
eventSource.addEventListener('open', (event) => {
console.log(event)
})
eventSource.addEventListener('message', (event) => {
console.log(event)
dataList.insertAdjacentHTML('beforeend', `
<li>${event.data}</li>
`)
})
</script>
</body>
</html>What's happening is that the If I don't use promises, only the first number gets sent and some weird stuff is happening on the server-side. I'm using a I hope my explanation of what's happening is clear. Is there any way to solve this problem (sending a response before the handler is finished?) |

Would it be possible to add support for server-sent events? They would be very useful for notifying changes for example.
