-# @backstage/core
-
-## 0.7.0
-
-### Minor Changes
-
-- 4c049a1a1: - Adds onClick and other props to IconLinkVertical;
-
- - Allows TriggerButton component to render when pager duty key is missing;
- - Refactors TriggerButton and PagerDutyCard not to have shared state;
- - Removes the `action` prop of the IconLinkVertical component while adding `onClick`.
-
- Instead of having an action including a button with onClick, now the whole component can be clickable making it easier to implement and having a better UX.
-
- Before:
-
- ```ts
- const myLink: IconLinkVerticalProps = {
- label: 'Click me',
- action: ,
- icon: ,
- };
- ```
-
- After:
-
- ```ts
- const myLink: IconLinkVerticalProps = {
- label: 'Click me',
- onClick: myAction,
- icon: ,
- };
- ```
-
-### Patch Changes
-
-- 40c0fdbaa: Added support for optional external route references. By setting `optional: true` when creating an `ExternalRouteRef` it is no longer a requirement to bind the route in the app. If the app isn't bound `useRouteRef` will return `undefined`.
-- 2a271d89e: Internal refactor of how component data is access to avoid polluting components and make it possible to bridge across versions.
-- bece09057: Improve rendering of multiple support item links in the `SupportButton`
-- 169f48deb: Added the color prop to TrendLine from the Sparklines props types to be able to have custom colors.
-- 8a1566719: Added a new useSupportConfig hook that reads a new `app.support` config key. Also updated the SupportButton and ErrorPage components to use the new config.
-- Updated dependencies [40c0fdbaa]
-- Updated dependencies [2a271d89e]

-
-- 3a58084b6: The `FlatRoutes` components now renders the not found page of the app if no routes are matched.
-- e799e74d4: Fix `OverflowTooltip` cutting off the bottom of letters like "g" and "y".
-- 1407b34c6: More informative error message for missing ApiContext.
-- 9615e68fb: Forward link styling of `EntityRefLink` and `EnriryRefLinks` into the underling
- `Link`.
-- 49f9b7346: Deprecate `type` of `ItemCard` and introduce new `subtitle` which allows passing
- react nodes.
-- 3a58084b6: Created separate `AppContext` type to be returned from `useApp` rather than the `BackstageApp` itself. The `AppContext` type includes but deprecates `getPlugins`, `getProvider`, `getRouter`, and `getRoutes`. In addition, the `AppContext` adds a new `getComponents` method which providers access to the app components.
-- 2c1f2a7c2: Introduced generic OverflowTooltip component for cases where longer text needs to be truncated with ellipsis and show hover tooltip with full text. This is particularly useful in the cases where longer description text is rendered in table. e.g. CatalogTable and ApiExplorerTable.

- - @backstage/theme@0.2.3
-
-## 0.5.0
-
-### Minor Changes
-
-- efd6ef753: Removed `InfoCard` variant `height100`, originally deprecated in [#2826](https://github.com/backstage/backstage/pull/2826).
-
- If your component still relies on this variant, simply replace it with `gridItem`.
-
-- a187b8ad0: Removed deprecated `router.registerRoute` method in `createPlugin`.
-
- Deprecated `router.addRoute` method in `createPlugin`.
-
- Replace usage of the above two components with a routable extension.
-
- For example, given the following:
-
- ```ts
- import { createPlugin } from '@backstage/core';
- import { MyPage } from './components/MyPage';
- import { rootRoute } from './routes';
-
- export const plugin = createPlugin({
- id: 'my-plugin',
- register({ router }) {
- router.addRoute(rootRoute, MyPage);
- },
- });
- ```
-
- Migrate to
-
- ```ts
- import { createPlugin, createRoutableExtension } from '@backstage/core';
- import { rootRoute } from './routes';
-
- export const plugin = createPlugin({
- id: 'my-plugin',
- routes: {
- root: rootRoute,
- },
- });
-
- export const MyPage = plugin.provide(
- createRoutableExtension({
- component: () => import('./components/MyPage').then(m => m.MyPage),
- mountPoint: rootRoute,
- }),
- );
- ```
-
- And then use `MyPage` like this in the app:
-
- ```tsx
-
- ...
- }>
- ...
-
- ```

-- cbbd271c4: Add initial RouteRefRegistry
-
- Starting out some work to bring routing back and working as part of the work towards finalizing #1536
-
- This is some of the groundwork of an experiment we're working on to enable routing via RouteRefs, while letting the app itself look something like this:
-
- ```jsx
- const App = () => (
-
-
-
- {' '}
- // catalogRouteRef
-
-
-
-
-
-
- // statusRouteRef
-
-
-
-
-
-
-
-
-
- // sentryRouteRef
-
-
-
-
-
-
-
-
-
-
-
-
-
-
-
- );
- ```
-
- As part of inverting the composition of the app, route refs and routing in general was somewhat broken, intentionally. Right now it's not really possible to easily route to different parts of the app from a plugin, or even different parts of the plugin that are not within the same router.
-
- The core part of the experiment is to construct a map of ApiRef[] -> path overrides. Each key in the map is the list of route refs to traversed to reach a leaf in the routing tree, and the value is the path override at that point. For example, the above tree would add entries like [techDocsRouteRef] -> '/docs', and [entityRouteRef, apiDocsRouteRef] -> '/api'. By mapping out the entire app in this structure, the idea is that we can navigate to any point in the app using RouteRefs.
-
- The RouteRefRegistry is an implementation of such a map, and the idea is to add it in master to make it a bit easier to experiment and iterate. This is not an exposed API at this point.
-
- We've explored a couple of alternatives for how to enable routing, but it's boiled down to either a solution centred around the route map mentioned above, or treating all routes as static and globally unique, with no room for flexibility, customization or conflicts between different plugins. We're starting out pursuing this options 😁. We also expect that a the app-wide routing table will make things like dynamic loading a lot cleaner, as there would be a much more clear handoff between the main chunk and dynamic chunks.
