Thank you to @Spotify for supporting my work on MSW. You are a huge reason why API mocking is getting better for everybody on the web. This year, we are rolling out something that nobody has ever even tried to achieve before, and your support makes that possible. ❤️

@storybookjs ♥️ @vitest_dev Here's a sneak peak on the Vitest integration, which seems to be quite promising so far: - See your stories in the Vitest VSCode extension - Run tests inline directly in the file - Inline errors for easy understanding and fixing them!
