# @backstage/plugin-techdocs

## 0.11.1

### Patch Changes

- 30ed662a3: Adding in-context search to TechDocs Reader component. Using existing search-backend to query for indexed search results scoped into a specific entity's techdocs. Needs TechDocsCollator enabled on the backend to work.

  Adding extra information to indexed tech docs documents for search.

- 434dfc5d4: Display [metadata.title](https://backstage.io/docs/features/software-catalog/descriptor-format#title-optional) for components on the TechDocs homepage, if defined; otherwise fall back to `metadata.name` as displayed before.

## 0.11.0

### Minor Changes

- c772d9a84: TechDocs sites can now be accessed using paths containing entity triplets of
  any case (e.g. `/docs/namespace/KIND/name` or `/docs/namespace/kind/name`).

  If you do not use an external storage provider for serving TechDocs, this is a
  transparent change and no action is required from you.

  If you _do_ use an external storage provider for serving TechDocs (one of\* GCS,
  AWS S3, or Azure Blob Storage), you must run a migration command against your
  storage provider before updating.

  [A migration guide is available here](https://backstage.io/docs/features/techdocs/how-to-guides#how-to-migrate-from-techdocs-alpha-to-beta).

  - (\*) We're seeking help from the community to bring OpenStack Swift support
    [to feature parity](https://github.com/backstage/backstage/issues/6763) with the above.

- 787bc0826: The TechDocs plugin has completed the migration to the Composability API. In
  order to update to this version, please ensure you've made all necessary
  changes to your `App.tsx` file as outlined in the [create-app changelog][cacl].

  - @backstage/integration-react@0.1.6
  - @backstage/plugin-catalog-react@0.4.1

## 0.10.2

### Patch Changes

- 9d40fcb1e: - Bumping `material-ui/core` version to at least `4.12.2` as they made some breaking changes in later versions which broke `Pagination` of the `Table`.
  - Switching out `material-table` to `@material-table/core` for support for the later versions of `material-ui/core`
  - This causes a minor API change to `@backstage/core-components` as the interface for `Table` re-exports the `prop` from the underlying `Table` components.
  - `onChangeRowsPerPage` has been renamed to `onRowsPerPageChange`
  - `onChangePage` has been renamed to `onPageChange`
  - Migration guide is here: https://material-table-core.com/docs/breaking-changes
- 11c370af2: Optimize load times by only fetching entities with the `backstage.io/techdocs-ref` annotation
- 2b1ac002d: TechDocs now uses a "safe by default" sanitization library, rather than relying on its own, hard-coded list of allowable tags and attributes.
- Updated dependencies
  - @backstage/core-components@0.2.0
  - @backstage/plugin-catalog-react@0.4.0
  - @backstage/core-plugin-api@0.1.4
  - @backstage/integration-react@0.1.5
  - @backstage/theme@0.2.9

## 0.10.1

### Patch Changes

- 9266b80ab: Add search list item to display tech docs search results
- 03bf17e9b: Improve the responsiveness of the EntityPage UI. With this the Header component should scale with the screen size & wrapping should not cause overflowing/blocking of links. Additionally enforce the Pages using the Grid Layout to use it across all screen sizes & to wrap as intended.

  To benefit from the improved responsive layout, the `EntityPage` in existing Backstage applications should be updated to set the `xs` column size on each grid item in the page, as this does not default. For example:

  ```diff
  -  <Grid item md={6}>
  +  <Grid item xs={12} md={6}>
  ```

- 378cc6a54: Only update the `path` when the content is updated.
  If content and path are updated independently, the frontend rendering is triggered twice on each navigation: Once for the `path` change (with the old content) and once for the new content.
  This might result in a flickering rendering that is caused by the async frontend preprocessing, and the fact that replacing the shadow dom content is expensive.
- 214e7c52d: Refactor the techdocs transformers to return `Promise`s and await all transformations.
- e35b13afa: Handle error responses in `getTechDocsMetadata` and `getEntityMetadata` such that `<TechDocsPageHeader>` doesn't throw errors.
- Updated dependencies
  - @backstage/core-components@0.1.6
  - @backstage/plugin-catalog-react@0.3.1

## 0.10.0

### Minor Changes

- 94a54dd47: Added a `migrateDocsCase()` method to TechDocs publishers, along with
  implementations for AWS, Azure, and GCS.

  This change is in support of a future update to TechDocs that will allow for
  case-insensitive entity triplet URL access to documentation pages which will
  require a migration of existing documentation objects in external storage
  solutions.

  See [#4367](https://github.com/backstage/backstage/issues/4367) for details.

### Patch Changes

- 537c37b0f: Fix displaying owned documents list by fetching associated entity relations
- 136a91974: Show a "Refresh" button to if the content is stale.
  This removes the need to do a full page-reload to display more recent TechDocs content.
- f1200f44c: Rewrite the `/sync/:namespace/:kind/:name` endpoint to support an event-stream as response.
  This change allows the sync process to take longer than a normal HTTP timeout.
  The stream also emits log events, so the caller can follow the build process in the frontend.
- 3af126cdd: Provide a Drawer component to follow a running build.
  This can be used to debug the rendering and get build logs in case an error occurs.
- 2a4a3b32d: Techdocs: fix sidebars not adjusting position automatically
- Updated dependencies

### Minor Changes

- ac6025f63: Add feedback link icon in Techdocs Reader that directs to GitLab or GitHub repo issue page with pre-filled title and source link.
  For link to appear, requires `repo_url` and `edit_uri` to be filled in mkdocs.yml, as per https://www.mkdocs.org/user-guide/configuration. An `edit_uri` will need to be specified for self-hosted GitLab/GitHub instances with a different host name.
  To identify issue URL format as GitHub or GitLab, the host name of source in `repo_url` is checked if it contains `gitlab` or `github`. Alternately this is determined by matching to `host` values from `integrations` in app-config.yaml.

### Patch Changes

- dbe4450c3: Google Cloud authentication in TechDocs has been improved.

  1. `techdocs.publisher.googleGcs.credentials` is now optional. If it is missing, `GOOGLE_APPLICATION_CREDENTIALS`
     environment variable (and some other methods) will be used to authenticate.
     Read more here https://cloud.google.com/docs/authentication/production

  2. `techdocs.publisher.googleGcs.projectId` is no longer used. You can remove it from your `app-config.yaml`.

- a6f9dca0d: Remove dependency on `@backstage/core-api`. No plugin should ever depend on that package; it's an internal concern whose important bits are re-exported by `@backstage/core` which is the public facing dependency to use.
- b3b9445df: AWS S3 authentication in TechDocs has been improved.

  1. `techdocs.publisher.awsS3.bucketName` is now the only required config. `techdocs.publisher.awsS3.credentials` and `techdocs.publisher.awsS3.region` are optional.

  2. If `techdocs.publisher.awsS3.credentials` and `techdocs.publisher.awsS3.region` are missing, the AWS environment variables `AWS_ACCESS_KEY_ID`, `AWS_SECRET_ACCESS_KEY` and `AWS_REGION` will be used. There are more better ways of setting up AWS authentication. Read the guide at https://backstage.io/docs/features/techdocs/using-cloud-storage

### Minor Changes

- dae4f3983: _Breaking changes_

  1. Added option to use Google Cloud Storage as a choice to store the static generated files for TechDocs.
     It can be configured using `techdocs.publisher.type` option in `app-config.yaml`.
     Step-by-step guide to configure GCS is available here https://backstage.io/docs/features/techdocs/using-cloud-storage
     Set `techdocs.publisher.type` to `'local'` if you want to continue using local filesystem to store TechDocs files.

  2. `techdocs.builder` is now required and can be set to `'local'` or `'external'`. (Set it to `'local'` for now, since CI/CD build
     workflow for TechDocs will be available soon (in few weeks)).
     If builder is set to 'local' and you open a TechDocs page, `techdocs-backend` will try to generate the docs, publish to storage and
     show the generated docs afterwords.
     If builder is set to `'external'`, `techdocs-backend` will only fetch the docs and will NOT try to generate and publish. In this case of `'external'`,
     we assume that docs are being built in the CI/CD pipeline of the repository.
     TechDocs will not assume a default value for `techdocs.builder`. It is better to explicitly define it in the `app-config.yaml`.

  3. When configuring TechDocs in your backend, there is a difference in how a new publisher is created.

  ```
  ---  const publisher = new LocalPublish(logger, discovery);
  +++  const publisher = Publisher.fromConfig(config, logger, discovery);
  ```

  Based on the config `techdocs.publisher.type`, the publisher could be either Local publisher or Google Cloud Storage publisher.

  4. `techdocs.storageUrl` is now a required config. Should be `http://localhost:7000/api/techdocs/static/docs` in most setups.

  5. Parts of `@backstage/plugin-techdocs-backend` have been moved to a new package `@backstage/techdocs-common` to generate docs. Also to publish docs
     to-and-fro between TechDocs and a storage (either local or external). However, a Backstage app does NOT need to import the `techdocs-common` package -
     app should only import `@backstage/plugin-techdocs` and `@backstage/plugin-techdocs-backend`.

  _Patch changes_

  1. See all of TechDocs config options and its documentation https://backstage.io/docs/features/techdocs/configuration

  2. Logic about serving static files and metadata retrieval have been abstracted away from the router in `techdocs-backend` to the instance of publisher.

  3. Removed Material UI Spinner from TechDocs header. Spinners cause unnecessary UX distraction.
     Case 1 (when docs are built and are to be served): Spinners appear for a split second before the name of site shows up. This unnecessarily distracts eyes because spinners increase the size of the Header. A dot (.) would do fine. Definitely more can be done.
     Case 2 (when docs are being generated): There is already a linear progress bar (which is recommended in Storybook).
