This is my Owl component in Odoo 15. It is meant to load chart lib from CDN.

/** @odoo-module **/

import { loadAssets } from "@web/core/assets"; //not working.
import { loadJS } from "@web/core/assets"; //not working.
import { registry } from "@web/core/registry"
import { useService } from "@web/core/utils/hooks";

const { Component } = owl;
const { onWillStart, useRef, onMounted } = owl.hooks;

export class ChartRenderer extends Component {
setup(){
this.chartRef = useRef("chart")
onWillStart(async ()=>{
await loadJS("https://cdnjs.cloudflare.com/ajax/libs/Chart.js/4.4.0/chart.umd.min.js")
//await loadAssets("/web/static/lib/Chart/Chart.js")
})
onMounted(()=>this.renderChart())
}
renderChart(){
//body
}
}

ChartRenderer.template = "my_module.ChartRenderer"

Upon loading the module, both loadJS() and loadAssets() within onWillStart function are throwing errors.

loadJS() error: 

"UncaughtPromiseError > ReferenceError

Uncaught Promise > loadJS is not defined.....


===========================
loadAssets() error: 

UncaughtPromiseError > TypeError

Uncaught Promise > Cannot use 'in' operator to search for 'bundles' in /web/static/lib/Chart/Chart.js.......


What am I not doing correctly? What is the correct way to load JS library within an Owl component?

Thanks.

Hi,

You can directly provide the link of the js library in your manifest in the asset keyeg:'assets':
        {'web.assets_backend': [
                                'https://cdn.jsdelivr.net/npm/chart.js',]},


Hope it helps
