* Refactor `StorageMenu` modals to replace deprecated patterns * add test for `DeleteBucketModal` and update test setup Note: Because this component uses `useParams`, it's necessary to have the dynamic route segment passed to `next-router-mock`'s `createDynamicRouteParser`. In order not to have to manually list all of these as the application grows, I added a glob utility that uses the `pages/` directory to automatically generate an array of dynamic route paths in this case. * add test for `EmptyBucketModal` * add test for `EditBucketModal` and add `isNonNullable` utility function * add test for `CreateBucketModal` * implement requested changes * implement visual fixes

/**
|
|
* Used to test whether a `Maybe` typed value is `null` or `undefined`.
|
|
*
|
|
* When called, the given value's type is narrowed to `NonNullable<T>`.
|
|
*
|
|
* ### Example Usage:
|
|
*
|
|
* ```ts
|
|
* const fn = (str: Maybe<string>) => {
|
|
* if (!isNonNullable(str)) {
|
|
* // typeof str = null | undefined
|
|
* // ...
|
|
* }
|
|
* // typeof str = string
|
|
* // ...
|
|
* }
|
|
* ```
