Fixing the the inferred type of ‘meta’ cannot be named rrror in Storybook

When I first encountered the “The inferred type of ‘meta’ cannot be named without a reference to…” message in Storybook, I was caught off guard. I wanted a quick solution that would keep my TypeScript checks happy and my Storybook setup running smoothly. After a bit of trial and error, I discovered a simple fix that anyone can implement.

The inferred type of ‘meta’ cannot be named without a reference to ‘@storybook/test/node_modules/@vitest/spy’. This is likely not portable. A type annotation is necessary.

1. Spotting the Problem
I noticed that the error showed up whenever I used the satisfies Meta<typeof Kiosk> approach in my stories. TypeScript decided to infer everything about meta in a way that pulled in references to internal types from @vitest/spy, which caused unwanted complexity.

2. Removing the Culprit
To resolve this issue, I removed the satisfies syntax. Instead of allowing TypeScript to infer the type in a way that caused the error, I switched to explicitly annotating my meta object.

3. Using a Direct Annotation
I replaced:

TypeScript
const meta = {
  ...
} satisfies Meta<typeof MyComponent>;<br>

with:

TypeScript
const meta: Meta<typeof MyComponent> = {
  ...
};

This direct annotation stopped TypeScript from inferring references to extra types and got rid of the error message.

Conclusion
By swapping out satisfies for a straightforward type annotation, I resolved the inference issue and kept my Storybook stories functioning as intended. This small change made my setup cleaner and more predictable. I hope this helps anyone struggling with a similar error.
