Hi,

Here are the steps on how to add new JavaScript libraries to Odoo 16:

Place the JS file:

Create a directory named static/src/js within your custom module if it doesn't exist.

Place the library's JavaScript file(s) within this directory.

Register the library in the manifest file:

Open your module's __manifest__.py file.

Under the assets section, add the library's path to the relevant asset list:

Python

'assets': {

    'web.assets_backend': [

        '/path/to/your/module/static/src/js/your_library.js',

        '/path/to/your/module/static/src/js/another_library.js',

   ],

},

Import and use the library in your code:

In your JavaScript files, you can now import and use the library as you would normally do:

JavaScript

import axios from 'axios'; // Example using axios

axios.get('https://api.example.com/data')

    .then(response => {

        // Handle the response

    })

    .catch(error => {

        // Handle errors

    });

Regards
