Simple Generator/Evaluator/Producer/Consumer System that sends a series of random arithmetic expression for evaluation

Challenge: Full-Stack

The assignment is to build a simple Producer/Consumer system. In this system the Generator will send a series of random arithmetic expressions, while the Evaluator will accept these expressions, compute the result and then report the solution to the Generator.

Requirements

At a minimum, we would like to see the following implemented:

The Producer and Consumer as separate NodeJS services. The Producer generating random addition expressions of two positive integers, e.g. "2+3=" The Consumer computing and returning the correct mathematical result for the each expression it receives The Consumer successfully processing requests from two Producers concurrently at a rate of at least 1 req/sec from each Producer (2 req/sec in aggregate) The Consumer and Producer should log all messages they generate and receive. You are free to support more than simple addition, but it is not required.

The end product should:

Be built in strict JavaScript and run with NodeJS NOT rely on any external services like Redis, ZeroMQ or similar technologies NOT use Express (Connect is Ok) Include UML Activity Diagram and UML Sequence Diagram documenting the business logic Include Unit tests

Note

This is very simple implementation. Nothing fancy to show the desired outcome.

Install libs

 $ npm i

Running tests

 $ npm test

Running the Consumer

 $ npm run consumer

Running the Producer

 $ npm run producer
