SmartCalculation-v3.0

Implementation of a calculator with a web interface in React, a service in Golang, and calculations in C++.

Content

This project implements a web calculator with the following capabilities:

1. Page navigation
2. Calculation of the value of a function at a point
3. Direct calculation
4. Graphing functions
5. Saving and using expression history

This project is a modification of the previous version of the calculator SmartCalculation-v2.0.

What was used:

1. Frontend - JS + React
2. Backend - Golang + Chi
3. Core - C++ + C

All components of the project are launched in separate docker containers and combined into one layer with using docker-compose. Accordingly, docker and docker-compose are required to run this application.

The application uses the following ports:

1. 3000 - frontend (main)
2. 8080 - backend

Frontend has the following endpoints:

1. / - home page, application navigation
2. /calculator - page with a calculator
3. /plot - page with plotting
4. /reference - help page

Backend has the following endpoints:

1. /api/calculator - calculate the value of an expression, query parameters: expression, x
2. /api/plot - calculation of function values ​​for plotting, query parameters: expression, begin, end
3. /api/previous_expression - returns the previous successfully evaluated expression
4. /api/clear_history - clears the history of expressions

To run the make application to clear the cache of the docker containers make clean.

Some examples of what the web interface looks like:

Home page
