@styra/ucast-prisma

This package contains helpers for using UCAST conditions with Prisma queries.

Usage

This package can be used to add filtering to Prisma queries from UCAST conditions. The conditions returned by the Enterprise OPA Compile API look like this:

{
  "conditions": {
    "or": [
      { "tickets.resolved": false },
      { "users.name": "ceasar" }
    ]
  }
}
Copy

A call to ucastToPrisma(conditions, "tickets") turns it into this Prisma query:

{
  "OR": [
    {
      "resolved": {
        "equals": false
      }
    },
    {
      "users": {
        "name": {
          "equals": "ceasar"
        }
      }
    }
  ]
}
Copy

A similar translation for masking rules is provided through the mask helper: E.g. the mask rules returned from the Compile API,

{
  "tickets.assignee": {
    "replace": {
      "value": "***"
    }
  },
  "users.name": {
    "replace": {
      "value": "<username>"
    }
  }
}
Copy

can be applied to a Prisma-returned object like

{
  "id": 200,
  "assignee": "bob",
  "users": {
    "id": 10,
    "name": "bobby"
  }
}
Copy

via mask(maskRules, obj, "tickets"), masking the appropriate fields.
