What you did:
I'm using Nuxt 2.0.0 and I tried using this plugin in one of my pages component.

What happened:

window is not defined

!function(e,t){if("object"==typeof exports&&"object"==typeof module)module.exports=t();else if("function"==typeof define&&define.amd)define([],t);else{var r=t();for(var n in r)("object"==typeof exports?exports:e)[n]=r[n]}}(window,function(){return function(e){var t={};function r(n){if(t[n])return t[n].exports;var i=t[n]={i:n,l:!1,exports:{}};return e[n].call(i.exports,i,i.exports,r),i.l=!0,i.exports}return r.m=e,r.c=t,r.d=function(e,t,n){r.o(e,t)||Object.defineProperty(e,t,{enumerable:!0,get:n})},r.r=function(e){"undefined"!=typeof Symbol&&Symbol.toStringTag&&Object.defineProperty(e,Symbol.toStringTag,{value:"Module"}),Object.defineProperty(e,"__esModule",{value:!0})},r.t=function(e,t){if(1&t&&(e=r(e)),8&t)return e;if(4&t&&"object"==typeof e&&e&&e.__esModule)return e;var n=Object.create(null);if(r.r(n),Object.defineProperty(n,"default",{enumerable:!0,value:e}),2&t&&"string"!=typeof e)for(var i in e)r.d(n,i,function(t){return e[t]}.bind(null,i));return n},r.n=function(e){var t=e&&e.__esModule?function(){return e.default}:function(){return e};return r.d(t,"a",t),t},r.o=function(e,t){return Object.prototype.hasOwnProperty.call(e,t)},r.p="",r(r.s=0)}([function(e,t,r){"use strict";r.r(t);var n={name:"vue-telegram-login",props:{mode:{type:String,required:!0,validator:function(e){return["callback","redirect"].includes(e)}},telegramLogin:{type:String,required:!0,validator:function(e){return e.endsWith("bot")||e.endsWith("Bot")}},redirectUrl:{type:String,default:""},requestAccess:{type:String,default:"read",validator:function(e){return["read","write"].includes(e)}},size:{type:String,default:"large",validator:function(e){return["small","medium","large"].includes(e)}},userpic:{type:Boolean,default:!0},radius:{type:String}},methods:{onTelegramAuth:function(e){this.$emit("callback",e)}},mounted:function(){var e=document.createElement("script");e.async=!0,e.src="https://telegram.org/js/telegram-widget.js?3",e.setAttribute("data-size",this.size),e.setAttribute("data-userpic",this.userpic),e.setAttribute("data-telegram-login",this.telegramLogin),e.setAttribute("data-request-access",this.requestAccess),this.radius&&e.setAttribute("data-radius",this.radius),"callback"===this.mode?(window.onTelegramAuth=this.onTelegramAuth,e.setAttribute("data-onauth","window.onTelegramAuth(user)")):e.setAttribute("data-auth-url",this.redirectUrl),this.$refs.telegram.appendChild(e)}},i=function(){var e=this.$createElement;return(this._self._c||e)("div",{ref:"telegram"})};i._withStripped=!0;var o=function(e,t,r,n,i,o,u,a){var s=typeof(e=e||{}).default;"object"!==s&&"function"!==s||(e=e.default);var l,d="function"==typeof e?e.options:e;if(t&&(d.render=t,d.staticRenderFns=r,d._compiled=!0),n&&(d.functional=!0),o&&(d._scopeId=o),u?(l=function(e){(e=e||this.$vnode&&this.$vnode.ssrContext||this.parent&&this.parent.$vnode&&this.parent.$vnode.ssrContext)||"undefined"==typeof __VUE_SSR_CONTEXT__||(e=__VUE_SSR_CONTEXT__),i&&i.call(this,e),e&&e._registeredComponents&&e._registeredComponents.add(u)},d._ssrRegister=l):i&&(l=a?function(){i.call(this,this.$root.$options.shadowRoot)}:i),l)if(d.functional){d._injectStyles=l;var c=d.render;d.render=function(e,t){return l.call(t),c(e,t)}}else{var f=d.beforeCreate;d.beforeCreate=f?[].concat(f,l):[l]}return{exports:e,options:d}}(n,i,[],!1,null,null,null);o.options.__file="src/vue-telegram-login.vue";var u=o.exports;r.d(t,"vueTelegramLogin",function(){return u})}])});

Problem description:
Seems like the window issue is caused by the client/server configuration. window is only available on the client side and the error is likely caused by the server rendering (which has no window)

Any idea how to solve this?

You should wrap you code with nuxt’s client-only component

You should wrap you code with nuxt’s client-only component

It doesn't work because it crashes during import

"dependencies": {
    "@nuxt/typescript-runtime": "^2.0.0",
    "@nuxtjs/axios": "^5.12.2",
    "core-js": "^3.6.5",
    "nuxt": "^2.14.5",
    "vue-telegram-login": "^2.1.0"
  }

I followed and official FAQ suggestion:

<template>
  <client-only placeholder="Loading...">
    <vue-telegram-login
      mode="callback"
      telegram-login="TrembolGameBot"
      @callback="yourCallbackFunction"
    />
  </client-only>
</template>

<script>
let vueTelegramLogin
if (process.client) {
  vueTelegramLogin = require('vue-telegram-login').vueTelegramLogin
  console.log(vueTelegramLogin)
} else {
  vueTelegramLogin = null
}

export default {
  name: 'TelegramLogin',
  components: {
    vueTelegramLogin,
  },
  methods: {
    yourCallbackFunction(user) {
      // gets user as an input
      // id, first_name, last_name, username,
      // photo_url, auth_date and hash
      console.log(user)
    },
  },
}
</script>
