What are the steps for generating an array of strings containing specific values?

Below is the code snippet:

type SearchSchemaValue =
    | 'tagName'
    | 'textContent'
    | 'attributes'
    | 'attributes.id'
    | 'attributes.class'
    | 'attributes.style';

export type SearchSchema = (SearchSchemaValue | string)[];

When I define const schema: SearchSchema = [', my IDE should ideally suggest values from SearchSchemaValue. However, it considers SearchSchema as string[].

How can you modify this type to be an array of strings with possible values from SearchSchemaValue?

typescript

Answer №1

What you really require is a flexible auto-complete feature

type SearchSchemaValue = FlexibleAutoComplete<'tagName' | 'textContent' | 'attributes' | 'attributes.id' | 'attributes.class' | 'attributes.style'>
  

type FlexibleAutoComplete<T extends string> = T | Omit<string, T>


export type SearchSchema = SearchSchemaValue[];


let k: SearchSchema = ["test", "tagName"]
