How to use with HTMX SSE

[simonjcarr]

I am trying to setup a simple test to get this working with HTMX SSE

In my controller I have

import transmit from '@adonisjs/transmit/services/main'
export default class MeetingsController {
    async meetingUpdates({ auth }: HttpContext) {
        const user = auth.user!
        if (!user) return response.status(401).json({ message: 'Unauthorized' })
        setInterval(async () => {
          transmit.broadcast('message', 'Hello world')
        }, 1000)
        console.log('Meeting updates')
      }
}

In my edge template I have

<div hx-ext="sse" sse-connect="/meeting/update_check" sse-swap="message">sdf</div>

I just get a stream of console.log messages in the adonisjs terminal every second, but the content of my div is never replaced with Hello world.
