tahsinature / grpc-demonstration

in this repository, you will kinda get an idea about gRPC and its integration with node application

the idea

• structure

  • create two services
  • call http call to service A
  • service A will call service B with gRPC
  • service B will send a response by processing the payload from service A
  • then service A will get the response from service B
  • then client will get the response from service A

  • in this repository: service A (Master) service B (Note)

• benchmark

  • call master service with HTTP call x amount of time
  • call master service with gRPC call x amount of time
  • take a note of those times & compare them

here is the result on my machine

Number of Calls	HTTP	gRPC
10	46.834ms	8.897ms
100	248.67ms	38.919ms
1000	1.746s	228.801ms
10000	17.038s	2.913s
50000	187.042s	15.179s

of course the result may vary depending on your machine. my spec:

  System:
    OS: macOS 11.4
    CPU: (12 Core) x64 Intel(R) Core(TM) i7-8750H -> CPU @ 4.1GHz
    Memory: 656.07 MB / 16.00 GB
    Shell: 5.8 - /bin/zsh

To run a service

npm run master
or,
npm run note

To run a specific file in

npx ts-node <file path>
# npx ts-node others/playground.ts

To run benchmark

npm run benchmark
