Can you create types with dynamic literals?

SynthLuvr · 2024-06-12T14:25:32.359Z

Say I have this function: ```ts const createType = (code: T) => { const literal: string = code; return type({ code: `'${literal}'` }); }; ``` With this I'm trying to create types with literals but I don't know those literals until runtime. If I run: ```ts const TypeONE = createType("ONE"); ``` It creates type: ```ts const TypeONE: Type ``` But instead what I'm actually wanting is: ```ts const TypeONE = type({ code: "'ONE'" }); ``` Which produces the correct type: ```ts const TypeONE: Type ```

Say I have this function:

const createType = <T extends string>(code: T) => {
  const literal: string = code;
  return type({
    code: `'${literal}'`
  });
};

const createType = <T extends string>(code: T) => {
  const literal: string = code;
  return type({
    code: `'${literal}'`
  });
};

With this I'm trying to create types with literals but I don't know those literals until runtime.

If I run:

const TypeONE = createType("ONE");

const TypeONE = createType("ONE");

It creates type:

const TypeONE: Type<{
    code: string;
}, {}>

const TypeONE: Type<{
    code: string;
}, {}>

But instead what I'm actually wanting is:

const TypeONE = type({
  code: "'ONE'"
});

const TypeONE = type({
  code: "'ONE'"
});

Which produces the correct type:

const TypeONE: Type<{
    code: "ONE";
}, {}>

const TypeONE: Type<{
    code: "ONE";
}, {}>
