Can pkl be used like jsonlogic also ?

[arundotin]

For some of our complex business rules, we use jsonlogic, to get appropriate JSON Configuration. For instance : if we give A as input to our rules in jsonlogic, then it will validate some rules and give us a JSON output and it will give a different output for B

This is useful, but not readable, testable and things like that ..

we are looking for an alternative to jsonlogic. Wondering if pkl can be used for such scenarios

Pkl definitely does this, albeit, it works a little differently to JSON logic.

With Pkl, you would define your validation and your data in Pkl, then have that produce JSON.

For example:

MyApplication.pkl

module MyApplication

port: UInt16(this > 1000)

output {
  renderer = new JsonRenderer {}
}

application.pkl

amends "MyApplication.pkl"

port = 1500

Then pkl eval application.pkl produces JSON to be consumed elsewhere.

You can also embed Pkl directly into your application without going through JSON, if there is an appropriate language binding for it.

Right now, Pkl has limited support for validating external JSON.
