Boldem Console App

The solution is made by several projects. The first project is Boldem.XmlGenerator, it's a simple console app used to generate a sample XML file. The second project is Boldem.ConsoleApp which is the main application; takes already generated XML file and imports contacts from this file using the Boldem API. Finally, the third project is just a xUnit Test project.

How to run it

To be able to run Boldem.ConsoleApp you have to define BOLDEM_ID and BOLDEM_SECRET environment variables. These variables are used as OAuth credentials to get a bearer token which is later used to call the API. The value of BOLDEM_ID is a Client ID and BOLDEM_SECRET is a client secret.

What can be improved

There are multiple areas where the project could be improved, namely:

• Using dependency injection container; intentionally the application doesn't use any DI container. The reason for that is simply because the app is too small and simple, however following the SOLID principles.
• OAuth service, the current implementation doesn't refresh the token. We import only 3000 contacts which can be easily imported in a couple hundred of milliseconds.
• Add rate limiting, again, if we would upload a hundred times more contacts we would probably need to add a rate limit to not overflow the API link.
• HTTP Client factory, you probably know what I am talking about.
• Consider using a delegate handler to attach a Bearer token, however, it has its own pros and cons.
• Domain modeling, currently we basically have no domain modeling, the candidate is eq. JWToken.
• Better UI, the app currently has basically no UI (unable to setup mailing list ID).
• Better UI abstraction, in the current implementation we're directly using the Console static class.
• Because the current app is basically a utility app, there is no architecture, we only use N layered architecture style.

As already mentioned, during the development I've followed next to the SOLID principles, YAGNI, and the Pareto principle.

Final words

If you've found this repository "by mistake" and you apply or going to apply for a developer position in Boldem, try to come up with your own solution. My solution the most definitely sucks... 😄
