[Feature request] Union type from array

[kreuzerk]

Hi @Jakob-em

Thanks a lot for the feature request. We already allow you to generate an Object of the types which you can use to iterate through. To generate this object you need to set the generateTypeObject flag to true.

The output will be something like this:

export type myIcons = 'expression_less' | 'full' | 'laughing' | 'smiling_face';

export const myIcons = {
  expression_less: 'expression_less' as myIcons,
  full: 'full' as myIcons,
  laughing: 'laughing' as myIcons,
  smiling_face: 'smiling_face' as myIcons
};

export interface MyIcon {
  name: myIcons;
  data: string;
}

Hi @kreuzerk,
Thanks for your quick answer. I know that the generation of a union type is currently possible, but the problem with union types is that you can not iterate over the possbile values. To solve this issue and allow for iteration over all icons I suggested to change the generation of the union type to be created via an immutable array. This would allow for both type safety, but also iterating the possible icons

Hi @Jakob-em. Yes, but you can iterate over the generated object by using Object.keys.

export const myIcons = {
  expression_less: 'expression_less' as myIcons,
  full: 'full' as myIcons,
  laughing: 'laughing' as myIcons,
  smiling_face: 'smiling_face' as myIcons
};

We first wanted to create an enum - here's what we discussed back then.

Ah yes your totally right, but this wouldn't work when using conversionType 'files' right? (Thats what i tried to use)

[kreuzerk]

It also works for converstionType files. But you need to set the generateTypeObject flag to true.

Let me know if there are issues or if you need help

[Jakob-em]

Now i get it. Yes this should work. Thanks for the quick help 👍

[kreuzerk]

No worries. Glad to hear that it works. 👍
