Calculator Microservice

This is a calculator application where individual operations are implemented as microservices in order to demonstrate tracing concepts.

Prerequisites

  • Go (tested on 1.13)
  • Node.JS

Installation and Usage

Right now, each service runs as a separate process on your machine, so you'll need to have several console windows open.

Client

  1. Switch to the web directory.
  2. Run npm install
  3. Run npm start

Server

  1. From the root directory, run go run cmd/<service>/main.go, where <service> is the name of the service you wish to run (api, add, etc.)

Notes

By default, all of the trace data for each service will be output to standard output. In your browser, you'll need to open the JavaScript console to see it; For the Go applications, it'll be in your console.
