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 🙏

MTA Plugin (Migration Toolkit for Applications)

Welcome to the MTA plugin for Backstage!

This plugin provides integration with the Migration Toolkit for Applications (MTA) service, allowing you to manage and analyze applications for migration.

This plugin was created through the Backstage CLI

Getting started

Your plugin has been added to the example app in this repository, meaning you'll be able to access it by running yarn start in the root directory, and then navigating to /mta.

You can also serve the plugin in isolation by running yarn start in the plugin directory. This method of serving the plugin provides quicker iteration speed and a faster startup and hot reloads. It is only meant for local development, and the setup for it can be found inside the /dev directory.

Authentication Setup

This plugin requires proper authentication with Keycloak to access the MTA API. If authentication is not set up correctly, you may experience 401 errors that can cause navigation issues in the UI.

Important: You must configure your Keycloak client with the appropriate scopes to use this plugin.

See our RHDH Setup Guide for detailed instructions on setting up the Keycloak client.

Deployment

For information on deploying this plugin with Red Hat Developer Hub (RHDH), see:

Troubleshooting

If you encounter issues with navigation or authentication:

  1. Ensure your Keycloak client is properly configured with the required scopes
  2. Check that your authentication tokens are valid
  3. Verify that your Backstage instance has the correct configuration

Authentication Error Handling

This plugin includes improved error handling for authentication issues:

  • Graceful handling of 401 errors without page navigation disruptions
  • Detailed error messages with specific instructions for fixing Keycloak configuration
  • Retry buttons that allow users to attempt requests again after fixing authentication issues
  • Prevention of hard refreshes and URL issues when authentication errors occur

For more details on authentication setup and troubleshooting, see our RHDH Setup Guide.
