TS Config: strictNullChecks #236
Description
Right now, the typescript configuration is not in strict mode and several important checks are not happening as they do in the frontend repo.
For example properties of an interface that are declared as string | undefined or string | null for example, are both treated as string and this exposes a risk when developing.
The goal of this issue is to configure typescript in a stricter mode and accommodate the code everywhere where after this change, typescript starts complaining.
