Describe requests/response payloads in a collection of interfaces.

• action
• data response from datasource
• notification

Trying not to reinvent the wheel and simply connect already existing user management service.

Ory Kratos documentation .

Replace to something else that just wokrs without console errors:

Also it should be something much simpler. In this project we need render only line charts.

Creating report has multiple stages and we can't just increment user report count just by 1 request. The stages are:

• check if user able to request report
• collect data from api's
• calculate custom values
• show data on frontend
  For example if for some reason we do not deliver requested data ( or some part of it ) - it should not be count as complete report and reports count should not be incremented.

So only if we deliver to client ALL requested data - we can increment user report count.

We can use "flow" approach like in kratos. Report flow should be initialized when user submit "ticker" form. Next this flow will be updated by report id on every step. The flow can be like this:

• initialize report
• get data from providerA.dataPart1 => save in redis
• get data from providerA.dataPart2 => save in redis
• get data from providerB.dataPart1 => save in redis
• get data from providerB.dataPart2 => save in redis
• ---- // ----
• calculate custom values => save in redis
• ensure frontend receive all data
• report is done

To not distarb real API. Also:

• data can be corrupted
• API can not response
• Can be slow.

Too complex template.

I want to try remove kratos-selfservice-ui-node service from infrastructure since it does not following main design and templates are not very customizeble. First step is to create login page.

It will allow to make cross schema JOINs and other usefull staff.

This request return this kind of values:

{
    "Meta Data": {
        "1. Information": "Monthly Prices (open, high, low, close) and Volumes",
        "2. Symbol": "IBM",
        "3. Last Refreshed": "2023-06-07",
        "4. Time Zone": "US/Eastern"
    },
    "Monthly Time Series": {
        "2023-06-07": {
            "1. open": "128.4400",
            "2. high": "134.4400",
            "3. low": "127.7800",
            "4. close": "134.3800",
            "5. volume": "22575373"
        },
        "2023-05-31": {
            "1. open": "126.3500",
            "2. high": "130.0699",
            "3. low": "120.5500",
            "4. close": "128.5900",
            "5. volume": "95710890"
        }
}

Which is difficult to transform into golang structure.

This is required here: https://github.com/shaninalex/financial-analyzer/blob/4-define-datasources/internal/datasource/service_alphavantage.go#L103

User can return to report and can ask to generate pdf version. Steps:

• initialize generating pdf
• complete generating report and save it into file
• save file into file storage and generate static link
• notify user with generated report

NOTE: Link sharing and advanced permissions will be in the next milestones.

when user create report - by default it is accessable only for owner. But user can share it for some one by email or make it accessable for all with the link. To do this I plan to use Ory Keto

The idea behind this task is to move all declaration code from services into separate script ( simular to kratos migration container ).

I allready start to do this here: 4493fd4
But it will be great to continue in separate branch.

Manager service is basically requests router. Because it should parse requests from frontend and "understand" which service responsible for particular request.

Also router should store users WS connections to be able to receive messages from "notification" service and send it to particular user. Or broadcast it to all users.

To reseach: if we have tons of user connections, how we manage them all? How we can actualy store them and get it not only from application memory, but from some kind of connections storage?

Ability to test without real api calls to datasources
