External stylesheet in custom element (no Polymer) - javascript

I'm building a custom element. this is my code:
<!DOCTYPE html>
<html>
<template>
<link rel="stylesheet" type="text/css" href="pols-notifier.css">
<div class="body">
<button class="close"></button>
<div class="content"></div>
</div>
</template>
<script>
class PolsNotifier extends HTMLElement {
constructor() {
super();
this.currentDocument = document.currentScript.ownerDocument;
}
connectedCallback() {
const instance = this.currentDocument.querySelector('template').content.cloneNode(true);
this.attachShadow({mode: 'open'}).appendChild(instance);
}
}
window.customElements.define('pols-notifier', PolsNotifier);
</script>
</html>
And the page is:
<!Doctype HTML>
<html>
<head>
<meta charset="utf-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width, initial-scale=1">
<link rel="import" href="http://localhost:8080/assets/pols-notifier/pols-notifier.html">
<body>
<pols-notifier></pols-notifier>
</body>
</html>
The console show an error when try load the stylesheet. The file of custom element and the stylesheet are in /assets/pols-notifier directory in my project but the navigator is looking /pols-notifier.css.
Why is looking there?
Greeting. Thanks.

Here you can see I have used map function to map through each data of storeData array, but it is not working, DOM shows nothing
var storeData=[]
const getData=()=>{
axios.get("https://api.coingecko.com/api/v3/coins/markets?

res=>{
storeData.push(res.data)
//console.log(storeData)
}
)
}
getData();
const myContent=document.querySelector(".myContent")
myContent.innerHTML=storeData.map((elem)=> {
return`
<div class='card'>
<div class="card-content">
<h3>${elem.name}</h3>
<h3>${elem.symbol}</h3>

With React your public files, such as JavaScript files, should be in a folder called 'public' in your React app, then in the index.html this should be denoted by '%PUBLIC_URL%'.
So in other words, move your assets folder to a folder called public and add '%PUBLIC_URL%/' before the paths for your files.

After 4 hour i found solition for my problem. It is define script links on component instead of index.html. Hope this post helps more people

When using iframe, I could not get the instance of left tree view. I want to get left tree view instance in index-10_2.html(right iframe source) to select and open respective node. I had use left=$("#1").contents(); to get the iframe content, var instance=left.find('#left'); to get instance, and instance.select_node(tm_id); to select node. But, error instance.select_node is not a function shown.

I had used document.getElementById('1').contentWindow.jQuery('#left').jstree(true); to get instance from iframe with id='1'. In order to listen to right iframe(with id='2') if any menu has been clicked, I used document.getElementById('2').contentWindow.jQuery('#right').on("changed.jstree",function(e,data){}). I get the instance of left iframe within this function. By using this instance, I has deselect previous selection, select current selection, and open children of selected menu.

When using and import statement and HTML I get no output. Why?

I am getting a blank page when using import. I have a simple program that is just to test the import statement. I don't know why I am not getting any output. Here is my code in app js:
import TestComponent from "./components/Testcomponentfile"
pageBuild();
function pageBuild(){
TestComponent();
}
Here is the code for the component:
export default function TestComponent(){
console.log("test component js");
return `
<h1>HTML test</h1>
`
}
And Here is the index.HTML:
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<meta http-equiv="X-UA-Compatible" content="ie=edge">
<script type="text/javascript"></script>
<title>Document</title>
</head>
<body>
<div id="demo"></div>
<div>
<h1> test Html</h1>
</div>
<script src="./JS/app.js"></script>
</body>
</html>
What am I missing??

Use type="module" in your html while using the script
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<meta http-equiv="X-UA-Compatible" content="ie=edge">
<script type="text/javascript"></script>
<title>Document</title>
</head>
<body>
<div id="demo"></div>
<div>
<h1> test Html</h1>
</div>
<script type="module" src="./JS/app.js"></script>
</body>
</html>

calling pageBuild(); after defining the function did not solve the problem>
I am using google chrome browser. It should be working.
import TestComponent from "./components/Testcomponentfile"
function pageBuild(){
TestComponent();
}
pageBuild();
Here is the code for the component:
export default function TestComponent(){
console.log("test component js");
return `
<h1>HTML test</h1>
`
}
an update to the first answer
tc.js
export default function TestComponent(){
console.log("test component js");
return `
<h1>HTML test</h1>
`
}
ap.js
import TestComponent from "./tc.js"
function pageBuild(){
console.log(TestComponent());
}
pageBuild();
tested and it works

How to get text from string confined between two specific words?

I get the whole HTML code from JSON using Ajax , The fetched string looks like :
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width, initial-scale=1">
..
</head>
<body>
<div class="container">
...
</div>
<div id="overlay"></div>
<script></script>
..
</body>
</html>
I want to get the whole code from the div with class container <div class="container"> to this one <div id="overlay"></div>.
How to accomplish that so that I just get the html part I want from the <body> not the whole string?

<script>
(function(window, document){
// `res` is the ajax response string
const res = `<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width, initial-scale=1">
</head>
<body>
<div class="container">
stuff from container.
</div>
<div id="overlay"></div>
</body>
</html>`;
const wrapper = document.createElement("div");
wrapper.innerHTML = res;
let str = '';
str+=wrapper.querySelector("div.container").outerHTML;
str+=wrapper.querySelector("div#overlay").outerHTML;
alert(str);
})(window, document);
</script>
