32- Logs & Profiling

1- Incorporar al proyecto de servidor de trabajo la compresión gzip.

  • instalat gzip
>npm i compression
  • inspeccionar en navegador rutas /info vs /info-gzip

2- Implementar loggueo

>npm i winston
  • ver archivo de configuracion en utils/logger.js

PERFORMANCE

  • Levantar servidor con --prof
>node --prof server.js
  • análisis con artillery
>artillery quick --count 5 --num 10 --output resultados.txt http://localhost:3000/info
  • Comparar performance en ambos casos . con y sin console.log(info)
  • Pasar log de profiler a txt
> node --prof-process  isolate-0x5911610-66286-v8.log > result-prof-debug.txt

Autocannon -> Misma funcionalidad que Artillery

  • levantar servidor
>node --prof server.js
  • correr análisis con autocannon (muy pareccido a artillery):
>autocannon -d 5 -c 10 "http://localhost:3000/info"

0x . Gráfico de flama (ohhh 🔥🔥🔥)

  • Levantar server con 0x
>0x server.js
  • Correr análisis con autocannon o artillery
>autocannon -d 5 -c 10 "http://localhost:3000/info"
