How to use npm packages in nuxtjs currently trying to use compress.js

Question

Currently trying to use the compress.js package to compress and image in nuxtjs.

But when it import it into the <script> tag it gives me an error. Cannot use import statement outside a module.

import Compress from "compress.js";

I tried adding it to the plugins directory and in nuxt.config.js like this.

nuxt.config.js

plugins: [
    { src: "~/plugins/compress-js.js", mode: "client" }
  ],

compress-js.js

import Vue from "vue";
import Compress from "compress.js";
Vue.use(new Compress());

But the error still comes. Any help would be appreciated.
