TypeScript Version: 3.1.3 2.9.2
Code
tsjs-crash.zip
Minimal example is in the attached zip package. Extract it somewhere, go to main directory with tsconfig.json and
install
npm i
compile
node node_modules/typescript/bin/tsc
Expected behavior:
everything works fine - preferred, because with TS 2.8.x there are no errors,
or some reasonable error message for problem solving
Actual behavior:
compiler crashes with
E:\projects\vscode-crash\node_modules\typescript\lib\tsc.js:69365
throw e;

Problem is with the imported javascript in TestComponent.tsx with
async exportToXlsx(exportSelected: boolean = false) {
const xlsx = await import('./js-xlsx/xlsx');
}
Problem is only with Typescript 2.9, 3.x, Typescript 2.8 compiles without any errors.
I tried to exclude javascript with tsconfig.json and jsconfig.json - see exclude properties in these files, but nothing works. Javascript is always compiled. So another question - is it possible exclude javascripts in similar situations?
