A Simple service for making a car maintainance booking app in which minimum 2 bookings will be acepted at a given point of time. One booking can have maximum of 2 hours. Working hours are 09:00 AM to 05:00 PM on everyday.

Used in memory database. Validations like duplicate VIN or duplicate email and phNo against DB are not performed to keep it simple. Have written unit test for very few files for complex logic. Integration tests are not covered. Cancellation of a booking is not covered. Change of booking date and time is not covered in this program. Just one time booking thats all. I have not added any pre-push hook to check for linting errors or to run tests if required let me know.

• npm
• node >= 14.x (will likely work with older versions, but has never been tested)

npm install

npm start will start the application at http://localhost:3000 (set environment variable PORT to change the port).

The service can now be called:

Below end point is to set capacity which means at a time how many cars can be accepted for booking. To set to default capacity which is 2 you can opt not to send anything in the request body.

$ curl --location --request POST 'http://localhost:3000/capacity/' \
--header 'Content-Type: application/json' \
--data-raw '{
    "noOfMechanics": 2
}'

Below End point is to get the capacity of the service station(in case needed):

curl --location --request GET 'http://localhost:3000/capacity/'

Below End point is to accept the booking:

curl --location --request POST 'http://localhost:3000/booking/' \
--header 'Content-Type: application/json' \
--data-raw '{
    "vehicle": {
        "VIN": "7897878979e8reahkra",
        "make": "HONDA",
        "model": "city"
    },
    "user": {
        "name": "Manas",
        "contact": "9861965513"
    },
    "bookingDateTime": "2021/05/21 15:00"
}'

Below End point will give you bookings made for a day along with slot information:
url: http://localhost:3000/booking/:date

curl --location --request GET 'http://localhost:3000/booking/2021-05-21'

Get booking by vehicle VIN
http://localhost:3000/booking/vin/:vin

curl --location --request GET 'http://localhost:3000/booking/vin/vehicleHondaCityVin_1'

Tests can be run with npm test.

All tests are colocated with their respective source files in *.spec.js files, using Jest with default settings. I have only written for few files due to time constraint.

You do not need to run the application separately to run any tests.

Linting has been added to the code from popular linter airbnb and some customezations also made on top of it.

To checking linting errors run npm run lint will show all errors and warning.
