Error: The token 'export' in d3zoom is causing a syntax issue

I'm encountering issues with executing tests in Angular:

  ({"Object.<anonymous>":function(module,exports,require,__dirname,__filename,global,jest){export {default as zoom} from "./zoom.js";
                                                                                             ^^^^^^

    SyntaxError: Unexpected token 'export'

      16 | import { scaleLinear } from "d3-scale";
      17 | import { event, mouse, select, Selection } from "d3-selection";
    > 18 | import { zoom, ZoomBehavior, zoomIdentity, ZoomTransform } from "d3-zoom";
         | ^
      19 | import { Observable, Subscription } from "rxjs";
      20 | import { map, tap } from "rxjs/operators";

I have attempted to follow advice on a different SO post, which recommended switching to a different node version (specifically node v12 instead of v14), but that did not resolve the issue.

Any suggestions on how to troubleshoot this?

Answer №1

Whether it's Jest or any other testing site you're using, make sure it supports JavaScript/CommonJS and not TypeScript/ES Modules. In other words, if you want to write tests in TypeScript, you'll need to use `require` or install `ts-node`. npm install -D ts-node. Alternatively, check if there is a package like `ts-jest` available for handling TypeScript tests.
