1.3. Install from CDN

Theory

THe modern way to import the library in the browser is to put it directly into the html code of the page. This is not supported by older browsers.

unpkg

<script type="module">
  import NgwMap from "https://unpkg.com/@nextgis/[package]@[version]/lib/[package].esm-browser.prod.js";
</script>

We recommend linking to a specific [version] number that you can update manually. This will help you to avoid problems that may occur when updating libraries.

Practice

To run this example, you need to execute these commands in the terminal:

npm i
npm start

Open http://localhost:8080.

If you open the file index.html in the console instead, the work of the example will not be complete. Requests to NGW will fail due to CORS limitations. Server https://demo.nextgis.com is configured to receive requests from http://localhost:8080 and http://127.0.0.1:5500.
