RESTAPI_Assignments

This repository contains all of my REST API Assignments & Projects

Problem Statement 1:

1. create middle ware method which check token key value = 'abc' in the request header and if token with value is not available return 401 status with message (Token must be provided)
2. Create api to calculate sum of a and b [a + b] [get] /sum - query [post] /sum - body
3. Create api to subtract a and b [a - b] validation : a should be greater than b else return 400 status with message (a should be greater than b) [get] /sub [post] /sub
4. Create api to multiply a and b [a * b] validation : a and b should be greater than 0 else return 400 status with message (a and b should be greater than 0) [get] /multi - [post] /multi
5. Create api to divide a and b. [a / b] validation : b should be greater than 0 else return 400 status with message b should be greater [get] /devi
   [post] /devi

server.js contains GET & POST API implementations for adding, subtracting, dividing and multiplying two numbers. It has in-function input validation as well as a global validation via a middle-ware (validate.js) which checks for a specific token in the request header.
