How to run?

Type the following in your terminal opened in the root of this repository

npm install (Installs the required modules like mongodb driver and express library)
node server.js (Runs the server)

How to access the server?

Use any request client - curl, Postman, etc.
The server is listening on port 3000 and the endpoint exposed is called /execute-query
The endpoint /execute-query requires a query parameter scriptname which is the name of the script (without the extension) to run

Assuming that you are running this locally, the entire request would look like:

GET http://localhost:3000/execute-query?scriptname=get-5-reviews
