Tailor extends EventEmitter, so you can subscribe to events with tailor.on('eventName', callback).
Events may be used for logging and monitoring. Check perf/benchmark.js for an example of getting metrics from Tailor.
- Client request received:
start(request) - Response started (headers flushed and stream connected to output):
response(request, status, headers) - Response ended (with the total size of response):
end(request, contentSize) - Error:
error(request, error)in case an error from template (parsing,fetching) and primary error(socket/timeout/50x) - Context Error:
context:error(request, error)in case of an error fetching the context
- Request start:
fragment:start(request, fragment.attributes) - Response Start when headers received:
fragment:response(request, fragment.attributes, status, headers) - Response End (with response size):
fragment:end(request, fragment.attributes, contentSize) - Error:
fragment:error(request, fragment.attributes, error)in case of socket error, timeout, 50x - Fallback:
fragment:fallback(request, fragment.attributes, error)in case of timeout/error from the fragment if the fallback-src is specified
Note: fragment:response, fragment:fallback and fragment:error are mutually exclusive. fragment:end happens only in case of successful response.
