Objecttype is described as a component within a different class or interface

I have a specific Data Interface that has the following structure:

interface Data {
    message: string;
    Id: string;
    uid: string;
}

When uploading data with this structure to a database, everything works smoothly. However, when it comes to updating a single element in the database by calling the function updateData(updatedData), I want the variable updatedData to be an object that follows the structure of the Data interface.

I have been struggling to find a solution for this issue and am having difficulty articulating my question concisely enough to yield relevant search results.

If you have any keywords or suggestions on how to approach this problem, I would greatly appreciate your input.

Answer №1

It seems like you are looking to work with a partial Data interface. In TypeScript, you can achieve this using the partial type.

interface IData {
  message: string;
  id: string;
  uid: string;
}

type partialData = Partial<IData>;

const messageData: partialData = {
  message: 'only message updated',
};

const idData: partialData = {
  id: 'only id updated',
};

const updateData = (data: partialData) => {
  console.log();
};

updateData(messageData);
updateData(idData);

As per the TypeScript definition:

type Partial<T> = { [P in keyof T]?: T[P] | undefined; }

This essentially makes all properties of the interface optional.
