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 organization’s 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 Backstage’s 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.

Project roadmap

Patch Changes

  • 8209449: Added new APIs for testing extensions
  • 72754db: Updated usage of useRouteRef, which can now always return undefined.
  • 3be9aeb: Added support for v2 extensions, which declare their inputs and outputs without using a data map.
  • fe1fbb2: Migrating usages of the deprecated createExtension v1 format to the newer v2 format, and old create*Extension extension creators to blueprints.
  • 2d21599: Added support for being able to override extension definitions.

    const TestCard = EntityCardBlueprint.make({
      ...
    });
    
    TestCard.override({
      // override attachment points
      attachTo: { id: 'something-else', input: 'overridden' },
      // extend the config schema
      config: {
        schema: {
          newConfig: z => z.string().optional(),
        }
      },
      // override factory
      *factory(originalFactory, { inputs, config }){
        const originalOutput = originalFactory();
    
        yield coreExentsionData.reactElement(
          <Wrapping>
            {originalOutput.get(coreExentsionData.reactElement)}
          </Wrapping>
        );
      }
    });
    
  • c00e1a0: Deprecate the .render method of the createExtensionTester in favour of using renderInTestApp directly.

    import {
      renderInTestApp,
      createExtensionTester,
    } from '@backstage/frontend-test-utils';
    
    const tester = createExtensionTester(extension);
    
    const { getByTestId } = renderInTestApp(tester.reactElement());
    
    // or if you're not using `coreExtensionData.reactElement` as the output ref
    const { getByTestId } = renderInTestApp(tester.get(myComponentRef));
    
  • 264e10f: Deprecate existing ExtensionCreators in favour of their new Blueprint counterparts.

  • 264e10f: Refactor .make method on Blueprints into two different methods, .make and .makeWithOverrides.

    When using createExtensionBlueprint you can define parameters for the factory function, if you wish to take advantage of these parameters you should use .make when creating an extension instance of a Blueprint. If you wish to override more things other than the standard attachTo, name, namespace then you should use .makeWithOverrides instead.

    .make is reserved for simple creation of extension instances from Blueprints using higher level parameters, whereas .makeWithOverrides is lower level and you have more control over the final extension.

  • 6349099: Added config input type to the extensions

Patch Changes

  • 516fd3e: Updated README to reflect release status

You can use the createAppRootElementExtension, createAppRootWrapperExtension, and createRouterExtension extension creator, respectively, to conveniently create such extensions. These are all optional, and if you do not supply a router a default one will be used (BrowserRouter in regular runs, MemoryRouter in tests/CI).
