Add property to object based on its data

It's so cool that Arktype turns into a most convenient and robust CSV->JSON parser ☺️

Add property to object based on its data

I handled it like this:

const product = type("Record<string, unknown>").pipe(r => {
  // Parse properties of r, create attributes
  r.attributes = ...;
  return r;
}).to({
  id: "string",
  attributes: type({
    "[string]": type({
      name: "string",
      value: "string"
    }),
  })
})

const product = type("Record<string, unknown>").pipe(r => {
  // Parse properties of r, create attributes
  r.attributes = ...;
  return r;
}).to({
  id: "string",
  attributes: type({
    "[string]": type({
      name: "string",
      value: "string"
    }),
  })
})

Yeah, I'd love to use the JSON Schema feature to improve the adapter for Superforms

Just started up a Deno project and used Arktype for CSV -> object validation, so incredibly convenient. Thank you again ☺️

Makes sense, thank you!

Empty string or number

That works, but I'd like to be able, if possible, to use a type directly so it can be easily chained to existing types

Empty string or number

It could be solved in the pipe function, but it would be nice to just be able to add an empty string type to another type, to avoid rewriting functions.

Empty string or number

I also have a currency type that I may want to apply the same logic to:

type("string | number").pipe((s) => currency(s))

type("string | number").pipe((s) => currency(s))

But same problem there.

Get keys of object type

That's some very cool introspection

Get keys of object type

That would be nice, then I can determine if it's a primitive js type

Get keys of object type

It works for me as well like that, but in value.expression it's Out<unknown>

Thanks for helping out on a saturday ☺️

Get keys of object type

Just found a thing, I have a "nullNumber" validator:

type('number').pipe((n) => (isNaN(n) ? null : n));

type('number').pipe((n) => (isNaN(n) ? null : n));

But when I look at value.expression for that, it looks like: '(In: number) => Out<unknown>' So I assume you cannot easily infer the type (at least not in the expression?) for pipe? If I use infer on the schema, I see that it's null | number at least.

I'll take a look at that, thanks!

Get keys of object type

props looks very good, I have a rather simple, non-nested object type so I'm looking for how to map the property types to a few of the primitive javascript types (string, number, boolean)

Is it possible to seed nested referenced entities?

I see that all tables are automatically seeded and references, even those not mentioned in the refine callback.
