How would you go about designing a flight booking app?

Question

Anonymous · Accepted Answer

I'm going to assume that a flight booking app would have these user stories
- user filters through certain information to get the flight they want
- user clicks on the flight towards and return flights. 
- user enters personal information as well as payment
- user then receives email confirmation on what they booked.

Then I'm also assuming that designers have designs ready to go.
I would first design the data model of the app, what models it needs, Flights,
Destinations, Dates, and connect them in whatever way needed so that the domain
layer is efficient and universal between different platforms. 
Then I would start designing the UseCases on what we would need to fetch and
post on the front end. This would then lead to planning out the endpoints needed
to implement for the front end to consume, as well as the request body and
response body.

At this point, assuming we don't have any design systems, i would implement the
front end page and slowly integrate the endpoints,  domain layer and data layer
on the front end with the view layer. Iteratate as we go along, and update any
needed changes or edge cases that we might've missed for the domain layer, and
update the endpoints as needed.

for the payment section, we would probably need to do a spike/research on which
payment app software we should utilize and how to implement on the front end,
before deciding on which to implement.
