- BAD Playwright Version: 1.35.0 and above
- Operating System: macOS
Code Snippet
Full reduced test case: https://github.com/OliverJAsh/playwright-pkg-require-with-path
Contents inlined below:
tsconfig.json:
{
"compilerOptions": {
"baseUrl": ".",
"paths": {
"app/*": ["app/*"]
}
}
}
app/my-pkg/main.ts:
export const foo = 1;app/my-pkg/package.json:
{
"main": "main.ts"
}
tests/example.spec.ts:
// ❌ Using path, it doesn't work.
import * as x from 'app/my-pkg';
// ✅ Not using path, it works.
// import * as x from '../app/my-pkg';
console.log(x);Describe the bug
Starting with Playwright 1.35.0, Playwright returns an error: Error: Cannot find module 'app/my-pkg'.
Note that if we change the import to avoid using the TS path (app/*), it works:
import * as x from '../app/my-pkg';
console.log(x);$ yarn
$ yarn playwright test
yarn run v1.22.19
Error: Cannot find module 'app/my-pkg'
