[Nx Plugin] Configure Vitest to use istanbul coverage by default

[yann-combarnous]

I use @nx/react with unitTestRunner set to vitest. How do I set default code coverage provider to istanbul? Based on https://nx.dev/nx-api/vite/generators/vitest, this is an option from Vitest generator, but not sure where to add it in nx.json

Assuming you are using @nx/react:app generator, there isn't an option to set the coverage provider for Vitest. You could run them as separate generators:

nx g @nx/react:app myapp --unitTestRunner=none
nx g @nx/vite:vitest --project=myapp --coverageProvider=istanbul
