How to create sidebar plugin that opens a link to another page

[sarg3nt]

I'm using the sidebar demo plugin and am stuck trying to figure out how to make a link open a new tab to an absolute URL.

I started by getting the plugin to work, then making minor changes.

I've cleaned it up so I have one new sidebar menu item called "Apps" which opens a sub menu that has my new link but I can't get that menu item to open a new tab to an absolute URL.

I haven't done front end dev work in years, so I'm super rusty and know nothing about tsx files.

Here's my current plugin code. Currently I'm loading what I want in an iFrame but I'd rather just have the 'Longhorn' link open a new tab.

import {
  registerRoute,
  //registerRouteFilter,
  registerSidebarEntry,
  //registerSidebarEntryFilter,
} from '@kinvolk/headlamp-plugin/lib';
import { SectionBox } from '@kinvolk/headlamp-plugin/lib/CommonComponents';
import Typography from '@mui/material/Typography';
import React from 'react';

// https://icon-sets.iconify.design/mdi/ for icons.

// The sidebar link URL is: /c/mycluster/apps
registerSidebarEntry({
  parent: null,
  name: 'apps',
  label: 'Applications',
  url: '/apps',
  icon: 'mdi:apps',
});

// Apps sub menus
// The sidebar link URL is: /c/mycluster/longhorn
registerSidebarEntry({
  parent: 'apps',
  name: 'longhorn',
  label: 'Longhorn',
  url: '/longhorn',
  // url: 'https:/longhorn.io', does not work.
});

// This component rendered at URL: /c/mycluster/apps
registerRoute({
  path: '/apps',
  sidebar: 'apps',
  name: 'apps',
  exact: true,
  component: () => {
    return (
      <SectionBox title="Applications" textAlign="center" paddingTop={2}>
        <Typography>See the sidebar for a list of applications.</Typography>
      </SectionBox>
    );
  },
});

//This component rendered at URL: /c/mycluster/longhorn
registerRoute({
  path: '/longhorn',
  sidebar: 'longhorn',
  name: 'longhorn',
  exact: true,
  component: () => (
    <SectionBox title="Longhorn" textAlign="center" paddingTop={2}>
      <iframe src="https://longhorn.k8s.vault.ad.selinc.com" title="Longhorn" width="100%" height="800px"></iframe>
    </SectionBox>
  ),
});

Hi @sarg3nt . Very cool that you're using the sidebar for such a use case. It's true the sidebar is not supporting URLs that are not in the app. I think it should.

I am not sure if the iframe is a work around for this or intended. If it's a work around, you could instead add the links to the view that the /apps route renders. Regular HTML should work, or you can import Link from mui.

@joaquimrocha yeah, it would be ideal directly opening a link was supported but I figured out a workaround for now.

registerRoute({
  path: '/longhorn',
  sidebar: 'longhorn',
  name: 'longhorn',
  exact: true,
  component: () => {
    window.open("https://longhorn.k8s.vault.ad.selinc.com", "_blank");
    return (
      <SectionBox title="Longhorn" textAlign="center" paddingTop={2}>
        <Typography>Opening Longhorn in a new tab...</Typography>
      </SectionBox>
    );
  },
});

It's ugly, but better than an iFrame

If you want to close this ticket you can, if you'd like to keep it open to track supporting links to external sites that works for me too.
