Migrate client API to codegen

[MichaelJamesParsons]

Description

The client app's API client is written by hand. Investigate what it would take to generate an API client from the routes defined the server app's routes.

Requirements/Expected Behavior

Generate an API client that is compatible with React Hooks. It should support the following use cases

Note: The API doesn't necessarily have to be consistent with the examples below.

Call directly from useEffect()

export function MyComponent() {
  useEffect(() => {
      makeTitanApiRequest(ListFileEntryTypes)
        .then(/* do something */);
  });
  return (...);
}

Wrap as a React hook

const fetchUsers = useTitanApiClient(ListOrganizationUsersRequest,
    { orgId: props.organizationId });
