* Support conditional `if` on scaffolder output links and text

Add `if` property to output link and text items in scaffolder templates,
allowing template authors to conditionally show/hide output items based
on parameters or step results. Items with a falsy `if` condition are
filtered out before being sent to the frontend.

* Refactor filterConditionalItems to use flatMap and generics

Replace .filter().map() with a single flatMap call and make the function
generic to eliminate JsonArray casts at call sites.

What is Backstage?

Backstage is an open source framework for building developer portals. Powered by a centralized software catalog, Backstage restores order to your microservices and infrastructure and enables your product teams to ship high-quality code quickly without compromising autonomy.

Backstage unifies all your infrastructure tooling, services, and documentation to create a streamlined development environment from end to end.

software-catalog

Out of the box, Backstage includes:

  • Backstage Software Catalog for managing all your software such as microservices, libraries, data pipelines, websites, and ML models
  • Backstage Software Templates for quickly spinning up new projects and standardizing your tooling with your organizations best practices
  • Backstage TechDocs for making it easy to create, maintain, find, and use technical documentation, using a "docs like code" approach
  • Plus, a growing ecosystem of open source plugins that further expand Backstages customizability and functionality

Backstage was created by Spotify but is now hosted by the Cloud Native Computing Foundation (CNCF) as an Incubation level project. For more information, see the announcement.
