JavaScript: subscribe

Subscribe registers your client with the server.

The optional callback receives a status and, on failure, an err argument. Log the full err so its cause, name, and any structured fields aren't hidden behind err.message.

Parameters

• callback

  (Optional)

• timeout

  (Required)

Examples

Handling errors

supabase.channel('room1').subscribe((status, err) => {
  if (status === 'CHANNEL_ERROR' || status === 'TIMED_OUT') {
    // Log the full error: its `cause` often holds the underlying reason.
    console.error(status, err)
  }
})
