Importing/Exporting JsonLogic with additional operators

Firstly, thank you very much for this library. It’s been a breeze to use!

I’m in the process of replacing react-awesome-query-builder with this package and have hit my first hitch.

We are using JsonLogic with some additional operators such as: JSONLogic.add_operation("lessThanOrEqualDate", isBeforeOrEqual);

When attempting to import a query that uses this operator with parseJsonLogic e.g.

{
  "query": {
    "and": [
      {
        "lessThanOrEqualDate": [
          {
            "var": "device.authenticatedAt"
          },
          "PT-24H"
        ]
      }
    ]
  }
}

Then passing it into parseJsonLogic it seems to strip it out. However, any condition that is using one of the defaultOperators works fine.

I assume it’s something to do with parseJsonLogic being scoped to the default operators. Is there anyway to let it recognise additional ones?

I don’t think you need to use transformQuery, just pass a custom ruleProcessor to formatQuery like below (CodeSandbox here):

import {
  defaultRuleProcessorJsonLogic,
  formatQuery,
  RuleGroupType,
  RuleType
} from "react-querybuilder";

const query: RuleGroupType = {
  combinator: "and",
  rules: [{ field: "device.authenticatedAt", operator: "<=", value: "PT-24H" }]
};

const jsonlgc = formatQuery(query, {
  format: "jsonlogic",
  ruleProcessor: (r: RuleType) => {
    if (r.field === "device.authenticatedAt") {
      return { lessThanOrEqualDate: defaultRuleProcessorJsonLogic(r)["<="] };
    }
    return defaultRuleProcessorJsonLogic(r);
  }
});

What that’s doing is taking '<=' property from the result of the default rule processor and assigning it to the lessThanOrEqualDate property of a new object (unless you’re dealing with a different field, in which case it just falls back to the default rule processor).

You may need to add some error checking and other contingencies but hopefully that gets you headed in the right direction.
