code

line-chart.component.ts

import { CommonModule } from '@angular/common';
import { Component } from '@angular/core';
import { HighchartsChartModule } from 'highcharts-angular';
// import * as Highcharts from 'highcharts/highstock';
import Highcharts from 'highcharts';
import HC_Stock from 'highcharts/modules/stock';
HC_Stock(Highcharts);

@component({
selector: "app-line-chart",
standalone:true,
templateUrl: "./line-chart.component.html",
styleUrls: ["./line-chart.component.scss"],
imports:[CommonModule, HighchartsChartModule]
})
export class LineChartComponent{
Highcharts: typeof Highcharts = Highcharts;

isHighcharts = typeof Highcharts === 'object';

chartOptions: Highcharts.Options = {
series: [
{
type: 'line',
pointInterval: 24 * 3600 * 1000,
data: [1, 2, 3, 4, 5],
},
],
};
}

line-chart.component.html

<highcharts-chart
*ngIf="isHighcharts"
[Highcharts]="Highcharts"
[constructorType]="'stockChart'"
[options]="chartOptions"

I am facing this issue

ERROR TypeError: Cannot read properties of undefined (reading 'Core/Globals.js')

, can you please provide an example code that implements SSR in Angular version 17 using standalone components or how can i fix this ?

node : v20.11.0
angular:17.1
npm 10.4.0

HI @borisdaev!

From Angular 17 SSR behaves differently than it used to with Angular Universal.
I've used the isBrowser flag instead of the isHighcharts, besides that it is business as usual.

Please see a standalone SSR component in the demo.

Internal note:
Let's improve the documentation and describe SSR in Angular 17.

Thank you for the demo code.
