Hyperactive expects a certain version of @types/web to be installed. This is because the library is built from the @types/web package, and the version of @types/web is used to determine the version of the library.

In the future, this may be relaxed, but for now, it is required if you work with Hyperactive on the client side. This decision was made because the library can be used in a server-side context, and the version of @types/web is not required in that case. Depending on a global lib.dom.d.ts pollutes the global scope and can cause unexpected type errors.

This table shows the version of @types/web that Hyperactive expects to be installed.
