Typescript failing to indicate that an object may be null or undefined

I can't seem to get TypeScript to recognize that types with | null are nullable. Take a look at the example below where I define the type:

type A = {
    b: {
        c: number;
        d: string;
    } | null;
};

When I hover over b, it doesn't indicate that it could be null. This lack of indication persists when I use the type elsewhere in my code.

Has anyone encountered this issue before and found a solution?

Answer №1

To enhance safety, it is recommended to activate the strictNullChecks feature in your TypeScript configuration file.

Alternatively, you can set

"strict":"true"
to enable a majority of strict rules for added security measures in your application.
