You have been asked to work on a project that will be used for calculating the area of different shapes. Your task is to build a RESTful API for the project using Node and Express into a file database.json. The list of supported shapes, their dimensions and formulas have been given below
| Shape | Dimensions | Formula for Area |
|---|---|---|
| Square | Side (side) | side * side |
| Rectangle | Length (length) and Breadth (breadth) | length * breadth |
| Triangle | Side a (length_a) Side b (length_b) Side c (length_c) | √s (s − length_a) (s − length_b) (s − length_c) where s is the semi_perimeter of the triangle calculated as s =( length_a + length_b + length_c) / 2 |
| Circle | Radius (radius) | πradius2 where pi is 3.14159... available in NodeJS as Math.PI |
A user can calculate the area of different shapes.
A user can fetch all previous computation record.
The application can be tested locally through localhost
- Run the application while postman is open
- Go to postman and test against the endpoints below with the required property:-
| Method | Endpoint | Enable a user to: |
|---|---|---|
| POST | /calculate | Calculate the area of different shapes |
| GET | /fetchRecords | Fetch all my previously computated data |
