Session Events (start, close) #842
Description
Is your feature request related to a problem? Please describe
I searched the documentation and only found this: https://nginx.org/en/docs/njs/reference.html#s_on
I would like to know when a stream (which would also have to be a session) starts and closes again.
Describe the solution you'd like
It would be nice to have "start" and "close" on the event ".on()" for stream and http.
- start: A connection from the client is incoming (first connection from the client)
- close: The client disconnects
And to be able to identify the session using an “ID”.
async(s: NginxStreamRequest): Promise<void> => {
r.on('start', () => {
const id = s.identifer();
....
});
r.on('close', () => {
const id = s.identifer();
// cleanup somthing
});
}
As an alternative (This is actually a better approach to get “start” as an event.), I could also imagine having to create an event object/function:
stream {
js_import mainstream from /opt/test.js;
...
server {
listen 80;
js_access mainstream.accessAddressStream;
js_session_event mainstream.sessionEvent;
...
}
}
test.js:
const accessAddressStream = async(s: NginxStreamRequest): Promise<void> => {
.....
}
const sessionEvent = async(event: SessionEvent, s: NginxStreamRequest|NginxHTTPRequest, ): Promise<void> => {
const id = s.identifer();
switch(event) {
case SessionEvent.start:
.....
break;
case SessionEvent.start:
.....
break;
}
.....
}
export default {accessAddressStream, sessionEvent};
