[Solved] Bundler: Failed to do transforms

LetsZiggy · September 2, 2020, 9:56pm

Hi,

I’m trying to move my side project to TypeScript. I’m new to TS. I get this error when added a file with method/function that returns a function (ie Aurelia Store nextStateHistory). Just adding the file, not even imported in the component, causes the error.

Any idea?

Error when npm start:

Because your target is ES2018, the ...state.present, is preserved and the old parser (esprima which cli-bundler uses) did not understand.

Thanks. Problem solved.
