Error `Unexpected token: punc ()` #290

Closed muety closed 2 years ago

I'm using geotiff.js as part of onaci/leaflet-geotiff-2 inside a Vue 2.x project and now get the following error when compiling.

js/chunk-edb17c18.8c64412d.js from Terser
Unexpected token: punc ()) [./node_modules/geotiff/dist-module/predictor.js:64,0][js/chunk-edb17c18.8c64412d.js:75,10]

ERROR  Build failed with errors.

This occurred after adding this import:

import { fromUrl } from 'geotiff'

The issue might also be caused downstream in the Leaflet plugin, but maybe someone here has got an idea?

Never mind, that was caused because my Webpack was configured to transpile to ECMAScript 5, but skip external dependencies and since geotiff.js is apparently using ES6 code, things failed.
