The following failure happens when updating to TypeScript 5.6.2

Updating to TypeScript 5.6.0-beta results in the same error. This can be solved by adding "@types/node": "^22.7.5" to /packages/components/package.json as devDependency.

That said, we probably also need to update typescript-eslint to 8.10.0 so that it supports TypeScript 5.6.

The following failure happens when updating to TypeScript 5.6.2

That's because the version of @types/node in packages/components is old, it's version 18.8.9. It's there because Storybook 7 depends on it explicitly. Rest of the repo depends on @types/node in the root node_modules, and there it's 22.10.10.

The difference between them is the signature of the ImportMeta.resolve function. In old versions it's optional (resolve?()), in the new version the ? optionality is no longer there.

A good solution that could work: edit packages/components/package.json and add @types/node: 22 dependency explicitly. Currently the v18 version is used by the entire components package, not just by Storybook, and that probably causes the errors.

Other Calypso packages like calypso-color-schemes or calypso-config already have this explicit dependency.

Yup, adding "@types/node": "^22.7.5" to /packages/components/package.json as devDependency solves that problem. After fixing some TS errors there's the next group of compatibility issues:

Edit: proposing #101590 to update TS to 5.6.2.

FWIW, updating TypeScript to 5.7.2 results in the following error:

[jsnajdr]

The "Debug Failure. False expression" error is reported here: microsoft/TypeScript#52952 Probably a TS bug. I'm trying to figure out what it means and where it comes from 🙂

[jsnajdr]

Fixed the "debug failure" error by removing unused and breaking file client/lib/shims/json.js. See microsoft/TypeScript#52952 (comment) and the replies to see why export default JSON is breaking.

Fortunately for us it turns out that file was unused 🙂
