# New Frontend System Support

Let a shared Backstage plugin live in both app generations

## What this does

You maintain a Backstage plugin that other people install. Backstage has a new frontend system, but not everyone has moved to it, and you cannot just drop the old one. This walks you through adding support for the new system while the old path keeps working, so one plugin serves both.

### Top 3 things it does for you

- Add new frontend system support to a plugin I maintain
- Keep the old system working for existing users
- Ship one plugin that runs in either kind of app

## About New Frontend System Support

For a Backstage plugin that is published or shared with others, moving to the new frontend system is not a clean break. Some of the apps installing your plugin have moved, and some have not.

This skill covers adding new frontend system support to an existing plugin while keeping the old system working, so the plugin functions in both old and new frontend system apps.
