Question

How can i make alias for built in type such as fromutility-types , i have definition which have the same name as builtin types, and happen to use type with the same name from builtin types, example :

interface Record { // <-- my definition

   toObject() : Record<string, object> // <-- built in definition
}

does not work

type TsRecord<K,V> = Record<K, V>

if there is an import method, i cant find the reference

import {Record as TsRecord} from ?

Answer 1

If you're using TypeScript 3.4 or above, you can use the globalThis namespace to access global types whose names have been shadowed by local declarations:

interface Record { // <-- my definition
  toObject(): globalThis.Record<string, object> // <-- built in definition
}

Okay, hope that helps; good luck!

Not sure why you have to use the name Record for your own definition but you could reuse the source for the record utility type for the custom TsRecord type:

type TsRecord<K extends keyof any, T> = {
  [P in K]: T;
};

interface Record {
  // <-- my definition
  toObject(): TsRecord<string, object>; 
}

Or rename your own definition:

interface TsRecord {
  // <-- my definition
  toObject(): Record<string, object>; 
}
