The process of generating generic interfaces in typescript

Implementing the functions below using TypeScript.

interface ActionType {
  // what's the code?
  type: string
};

let actionType: ActionType<{list: any}> = {
  type: 'type',
  list: []
}

Answer №1

It seems like your question pertains to a standard intersection type

//              Common type
//              |      Intersection type
//              ↓      ↓
type ActionType<T> = T & { action: string };

const actionType: ActionType<{data: any[] }> = {
  action: 'action',
  data: []
};
