unsubscribe
Helper to unsubscribe a collection of functions from the corresponding channels. This is the same as calling channel.unsubscribe(onMessage)
on each channel individually.
import diagnostics_channel from 'node:diagnostics_channel';
const channels = diagnostics_channel.tracingChannel('my-channel');
channels.unsubscribe({
start(message) {
// Handle start message
},
end(message) {
// Handle end message
},
asyncStart(message) {
// Handle asyncStart message
},
asyncEnd(message) {
// Handle asyncEnd message
},
error(message) {
// Handle error message
},
});
