"type": "module" in package.json breaks imports and prevents from execution on node 23 #2152
Description
I've got a *.ts file which imports a *.tsx file.
The pasted GitHub Actions workflow is a self-contained reproducer and completes successfully.
But if I remove sed -i 's@"type": "module",@@' package.json, it starts erroring out
Error: Cannot find module '/home/runner/work/lexical-cli-render/lexical-cli-render/EmojiNode' imported from /home/runner/work/lexical-cli-render/lexical-cli-render/lexical-cli-render-tsx.ts
Did you mean to import "./EmojiNode.tsx"?
If I change import { EmojiNode } from './EmojiNode' to import { EmojiNode } from './EmojiNode.tsx', the error becomes:
(node:1637) ExperimentalWarning: Type Stripping is an experimental feature and might change at any time
(Use `node --trace-warnings ...` to show where the warning was created)
TypeError: Unknown file extension ".tsx" for /home/runner/work/lexical-cli-render/lexical-cli-render/EmojiNode.tsx

it seems that
ts-nodehave no activity over 1 year. maybe we need to switch it toswci have create new repo and replace
ts-nodewithswcsee here. https://github.com/hyperse-io/ts-nodeacomagu commentedon Jun 15, 2025
You are seemed to be using Node native TypeScript support instead of ts-node. Try
--no-experimental-strip-typestats-u commentedon Aug 21, 2025
--experimental-strip-typesis now default even in 22.18.https://nodejs.org/en/blog/release/v22.18.0
