In the process of developing an ecommerce web application with next.js and typescript, I found myself declaring similar interfaces across various pages and components. Is there a method to create global interfaces that can be utilized by all elements within the project?
In my opinion, importing the types is a better approach. However, if you prefer creating the types globally, you can achieve this by creating a custom.d.ts file in the root directory of your application and defining the types there.
declare global {
interface User {
name: string;
email: string;
}
}
While this method will work, I personally do not recommend using it.
@Pranta's response is accurate, however it is important to remember to export at the conclusion.
declare global {
interface Person {
fullName: string;
emailAddress: string;
}
}
export default global;
