I am using vite with nx setup. I am trying to use jest-dom. Tests is running fine. But I am not able to resolve typescript type.

I've just run into the same issue of not having the vitest expect types include the jest-dom matchers, but in my case it was when using yarn with the pnpm nodeLinker.
What I found after investigation was that I needed to add @vitest/expect to my project's devDependencies for the types provided by @testing-library/jest-dom/vitest to work properly.
My investigations:
I tried copying the type augmentation from @testing-library/jest-dom/vitest into one of my test files, and typescript complained that the module @vitest/expectdidn't exist even though it had been installed by other libs.
Yarn pnpm only symlinks the dependencies that you declare in your package.json file in the top-level/project's node_modules directory. Any dependencies for other modules are only linked inside their local node_modules and not available for you to import into your own project files.
This meant that while other vitest libs pulled in @vitest/expect as a dependency, it wasn't available at the top level node_modules directory.
The consequence was that the type augmentation in @testing-library/jest-dom/vitest.d.ts wasn't able to be applied to the @vitest/expect module - there wasn't a node_modules/@vitest/expect directory representing the module to be augmented.
By adding the devDependency for @vitest/expect to my package.json file, it was then linked in my project's node_modules directory allowing the types shipped with @testing-library/jest-dom/vitest to find the @vitest/expect package types to be updated.
