CodePudding user response:

import is a feature of ES6 modules (and TypeScript modules).

While browsers do support it:

  • they only do so if you declare your script to be a module
  • they do not support Node.js style module resolution and require a URL which is either absolute, or starts with a / or a ..

It is more typical to use modules in combination with a bundler such as Webpack or Parcel.

That said, you need to read the documentation:

You cannot request a different domain from your web app (Browsers block cross-origin-requests). If you don't know how same-origin-policy works, here is a good intro, therefore this library works on node (back-end environments) and certain mobile run-times (cordova or react-native).

You might consider creating a webservice using Node.js and Express.js then accessing it with Ajax from your client side code.

CodePudding user response:

You can convert your file into a module or use the require syntax For the first solution please add :

{
  "type": "module"
}

in your package.json file. I hope it solves your issue!
