Backend (example-backend, or backends created with @backstage/create-app)
- The default mount point for backend plugins have been changed to
/api. These changes are done in the backend package itself, so it is recommended that you sync up existing backend packages with this new pattern. #2562 - A service discovery mechanism for backend plugins has been added, and is now a requirement for several backend plugins. See packages/backend/src/index.ts for how to set it up using
SingleHostDiscoveryfrom@backstage/backend-common. Note that the default base path for plugins is set to/apito that change, but it can be set to use the old behavior via thebasePathoption. #2600
@backstage/auth-backend
- The default mount path of backend plugins was changed to
/api/:pluginId, and as part of that it was needed to enable configuration of the base path of the auth backend, so that it can construct redirect URLs correctly. Note that you will also need to reconfigure any allowed redirect URLs to include/apiif you switch to the new recommended pattern. #2562 - The auth backend now requires an implementation of
PluginEndpointDiscoveryfrom@backstage/backend-commonto be passed in asdiscovery. See the changes to@backstage/backend.
@backstage/proxy-backend
- The proxy backend now requires an implementation of
PluginEndpointDiscoveryfrom@backstage/backend-commonto be passed in asdiscovery. See the changes to@backstage/backend.
@backstage/techdocs-backend
- The TechDocs backend now requires an implementation of
PluginEndpointDiscoveryfrom@backstage/backend-commonto be passed in asdiscovery. See the changes to@backstage/backend.
@backstage/plugin-identity-backend
- This plugin was removed, remove it from your backend if it's there. #2616
