ODLUX DB API Extension for Userdata

To be able to save user-specific data, such as settings for the NetworkMap (customization options) or the dashboard, the data-provider (Data-Provider) should be extended.

Goal:

• Provide a function to GET settings data by username
• Provide a function to POST / (PUT / PATCH?) settings data for a specific user
• Provide a function to DELETE settings data of a specific user
• no clear payload data structure definition to keep it as flexible as possible => what is written, can be requested

Characteristics:

• user gets identified by token (basicAuth or JWT)
• Additional API in bundle data-provider
• Create a settings entry in the database if none exists
• Delivers back all settings of a user
• Updates the settings of a user 
• Can delete (reset) settings of a user

 Open Questions:

• when should the initial settings entry of a user be created? When settings are updated / saved for the first time?
  • UI is responsible for data-structure → so initial data is writting by UI
  • empty data on server will return empty json object: "{}"
• Use PUT or PATCH for updating entries? (settings may grow over time, eg. dashboard, networkmap, ...) Should the entire settings object be send or only a partial one?
  • PUT!
  • partial will be implemented
• If we use PUT, do we need POST?
  • no
• Should settings be queryable by section? ( eg. dashboard, networkmap, ...)
  • filter only for root element key

Extension of data-provider

Examples

Read settings data of a user

GET /userdata

{
    "networkMap":{
        "startupPosition": {"lat": 52.5095, "lon":13.3290, "zoom": 10},
        "tileOpacity": 90,
        "styling":{
            "theme": "light"
        }
    },
    "dashboard":{
        "color":"#F00"
    }
}

GET /userdata/networkMap

{
    "startupPosition": {"lat": 52.5095, "lon":13.3290, "zoom": 10},
    "tileOpacity": 90,

    }
}

Write settings data of a user

        "tileOpacity": 90,
        "styling":{
