extends Array support is breaking ts-node

[binarykitchen]

ts-node is throwing this error when you use the new feature, have an array under extends and run Jest tests whose config files are in TS:

when having

"extends": ["@artemis/tsconfig-node/tsconfig", "@tsconfig/create-react-app/tsconfig"],

Perhaps you need to update ts-node? Or send them a PR helping their support for array extends 👍🏻

Already using latest version here and sorry, as a father I do not have time.

This is already fixed in ts-node, but not yet in a release. See TypeStrong/ts-node#1958

There does not seem to be any immediate plan to release a version with support for Typescript v5. This is likely the early days of many similar issues across different repos (like this one and commitlint) as people begin to upgrade to v5.

ts-node recommends installing from git to get latest changes which is not a great solution for us.

Not only ts-node, also tsconfig-resolver is not parsing array on extension attribute :(
This breaks eslint and bunch of other frameworks...

I have ticket for that:
