Default property value in React component using TypeScript

Question

I can\'t figure out how to set default property values for my components using Typescript.

This is the source code:

class PageState
{
}

export class

With Typescript 2.1+, use Partial < T > instead of making your interface properties optional.

export interface Props {
    obj: Model,
    a: boolean
    b: boolean
}

public static defaultProps: Partial<Props> = {
    a: true
};
