Additional API endpoint for last business-type updates in the TruBudget system

[jzakotnik]

To better understand, how often data in a TruBudget system is updated, it would be nice to have an API endpoint, that returns the last e.g. 10 updated timestamps, when something was changed in the system. Potentially also if it was project, subproject or workflow item.

For permission reasons, there doesn't need to be more detailed data.

With the API endpoint, one could integrate this in the dashboard for trubudget operations.

Hello there, I would like to take this and work on it.

[jzakotnik]

@amha-mersha Thank you very much for the contribution. Do you need any help describing what is useful and how to implement it?

[amha-mersha]

Yes, that would be great if it's not a burden. If you would show me the file/folder I'll be working on some description resources about the project

@amha-mersha I believe I would follow this approach:

• Install docker
• Start TruBudget from a container, using

cp scripts/operation/.env.example scripts/operation/.env
bash scripts/operation/start-trubudget.sh --slim

• Once started, the API documentation is available under http://localhost:3000/api/documentation/static/index.html. So you should see the swagger documentation. Does this work?
• Have a look at api/src/system/getVersion.ts, this is a good example which corresponds to http://localhost:3000/api/documentation/static/index.html#/system/get_api_version. Here you see the object multichainClient, which is the entry point to retrieve respective information from the multichain-blockchain. Does this work?

Let's have a quick break here and check if this works for you, then we can further deep dive into the code.
