root.addEventListener is not a function

kentjas1 commented 6 years ago

I'm also running into this issue when I am updating my app to use Webpack. I am using the ES6 import to include the npm package I installed.

import echo from "echo-js";

Also got this issue not using es6 import but with webpack

Hi @zlokomatic @kentjas1 I have the same issue with webpack. What is the solution ?

toddmotto commented 4 years ago

@pierre-dickinson It's probably due to this and webpack bundling in 'strict mode' as this may be undefined and therefore throw an error as addEventListener won't exist:

You can change the this to window and that should solve it.
