To use first run

git clone https://bitbucket.org/wonderbill/datahog.git && npm install + npm run start

Once the Server is running, run npm install && npm run build:start

Once server is running, you can send a request using postman or curl

Postman:

POST http://localhost:8000

Body

{
    "provider" : ["internet", "gas"],
    "callbackUrl" : "http://localhost:8000/data"
}

CURL

curl --location --request POST 'http://localhost:8000' --header 'Content-Type: application/json' --data-raw '{"provider" : ["internet", "gas"],"callbackUrl" : "http://localhost:8000/data"}'

Notes:

• I fun doing this work its very rarely that i get to do work from scratch
• Once a successful request has been made the application stores the last success request and resend is if a new request fails
• If the first request is unsuccessful then nothing is returned to the callbackURL
• The last request would be stored in a database but I don't have a lot of experience using MongoDB
• I had a hard time with some of the test
