Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Readme

Notifications

This Backstage front-end plugin provides:

  • the Notifications page listing notifications from the logged-in user's perspective
  • the NotificationsApi for accessing the notifications backend from front-end plugins
  • an active item to the main left side menu to both notify the user about new messages and provide navigation to the Notifications page
  • an alert about new system notifications

Getting started

Prerequisities

Have @janus-idp/plugin-notifications-backend installed and running.

Installing as a dynamic plugin

The sections below are relevant for static plugins. If the plugin is expected to be installed as a dynamic one:

  • follow https://github.com/janus-idp/backstage-showcase/blob/main/showcase-docs/dynamic-plugins.md#installing-a-dynamic-plugin-package-in-the-showcase
  • add content of app-config.janus-idp.yaml into app-config.local.yaml.
  • customize configuration configure as needed

Configuration

There is polling used to check for new notifications. It can be tuned via pollingIntervalMs config property (see app-config.janus-idp.yaml). When set to 0, the polling is turned off.

Installing as a static plugin

Add NPM dependency

cd packages/app
yarn add @janus-idp/plugin-notifications

Add left-side menu item

In the packages/app/src/components/Root/Root.tsx:

import { NotificationsActiveIcon } from '@janus-idp/plugin-notifications';

...
export const Root = ({ children }: PropsWithChildren<{}>) => (
    ...
      {/* New code: */}
      <SidebarDivider />
      <SidebarItem icon={NotificationsActiveIcon} to="notifications" text="Notifications" />

      {/* Existing code for reference: */}
      <SidebarSpace />
      <SidebarSpace />
      <SidebarDivider />
      <SidebarDivider />
      <SidebarGroup
        <SidebarGroup label="Settings"

Add to router

In the packages/app/src/App.tsx:

import { NotificationsPage } from '@janus-idp/plugin-notifications';
...

export const AppBase = () => {
    ...
      {/* New code: */}
      <Route path="/notifications" element={<NotificationsPage />} />

How to use the NotificationApi

Once installed as either static or dynamic plugin, a 3rd party frontend plugin can access the notifications via its frontend API:

import { notificationsApiRef, Notification } from '@janus-idp/plugin-notifications';

...

const notificationsApi = useApi(notificationsApiRef);
const notifications: Notification[] = await notificationsApi.getNotifications(params);

See src/api/notificationsApi.ts for more details.
