## 0.5.0

### Minor Changes

- 88480e4: **BREAKING**: The proxy backend plugin is now protected by Backstage auth, by
  default. Unless specifically configured (see below), all proxy endpoints will
  reject requests immediately unless a valid Backstage user or service token is
  passed along with the request. This aligns the proxy with how other Backstage
  backends behave out of the box, and serves to protect your upstreams from
  unauthorized access.

  A proxy configuration section can now look as follows:

  ```yaml
  proxy:
    endpoints:
      '/pagerduty':
        target: https://api.pagerduty.com
        credentials: require # NEW!
        headers:
          Authorization: Token token=${PAGERDUTY_TOKEN}
  ```

  There are three possible `credentials` settings at this point:

  - `require`: Callers must provide Backstage user or service credentials with
    each request. The credentials are not forwarded to the proxy target.
  - `forward`: Callers must provide Backstage user or service credentials with
    each request, and those credentials are forwarded to the proxy target.
  - `dangerously-allow-unauthenticated`: No Backstage credentials are required to
    access this proxy target. The target can still apply its own credentials
    checks, but the proxy will not help block non-Backstage-blessed callers. If
    you also add `allowedHeaders: ['Authorization']` to an endpoint configuration,
    then the Backstage token (if provided) WILL be forwarded.

  The value `dangerously-allow-unauthenticated` was the old default.

  The value `require` is the new default, so requests that were previously
  permitted may now start resulting in `401 Unauthorized` responses. If you have
  `backend.auth.dangerouslyDisableDefaultAuthPolicy` set to `true`, this does not
  apply; the proxy will behave as if all endpoints were set to
  `dangerously-allow-unauthenticated`.

  If you have proxy endpoints that require unauthenticated access still, please
  add `credentials: dangerously-allow-unauthenticated` to their declarations in
  your app-config.

## 0.4.0

### Minor Changes

- 71114ac50e02: **BREAKING**: The export for the new backend system has been moved to be the `default` export.

  For example, if you are currently importing the plugin using the following pattern:

  ```ts
  import { examplePlugin } from '@backstage/plugin-example-backend';

  backend.add(examplePlugin);
  ```

  It should be migrated to this:

  ```ts
  backend.add(import('@backstage/plugin-example-backend'));
  ```

### Patch Changes

- 02ba0a2efd2a: Add the route name to an error message that appears when the backend
  proxy wasn't well configured. This will help users to understand the
  issue and fix the right configuration.
- 03691f0f3270: Add back the legacy proxy config, to get secret redaction

## 0.2.37

### Patch Changes

- 52b0022dab7: Updated dependency `msw` to `^1.0.0`.
- 3e3eea4bc7e: The proxy-backend plugin now supports reviving request bodies that have previously been consumed by an express middleware (e.g. `express.json()`). This is done by setting `reviveConsumedRequestBodies: true` on the proxy `RouterOptions`. In order to preserve the current behavior, the proxy will **not** revive request bodies by default.

  The following is an example of a proxy `createRouter` invocation that revives request bodies:

  ```diff
  const router = await createRouter({
    config,
    logger,
    discovery,
  + reviveConsumedRequestBodies: true,
  });
  ```

- 4acd93dae1d: Ensure that `@backstage/plugin-proxy-backend` logs the requests that it proxies when log level is set to `debug`.

## 0.2.17

### Patch Changes

- 332d3decb2: Adds a new option `skipInvalidTargets` for the proxy `createRouter` which allows the proxy backend to be started with an invalid proxy configuration. If configured, it will simply skip the failed proxy and mount the other valid proxies.

  To configure it to pass by failing proxies:

  ```
  const router = await createRouter({
    config,
    logger,
    discovery,
    skipInvalidProxies: true,
  });
  ```

  If you would like it to fail if a proxy is configured badly:

  ```
  const router = await createRouter({
    config,
    logger,
    discovery,
  });
  ```

## 0.2.14

### Patch Changes

- bab752e2b3: Change default port of backend from 7000 to 7007.

  This is due to the AirPlay Receiver process occupying port 7000 and preventing local Backstage instances on MacOS to start.

  You can change the port back to 7000 or any other value by providing an `app-config.yaml` with the following values:

  ```
  backend:
    listen: 0.0.0.0:7123
    baseUrl: http://localhost:7123
  ```

### Patch Changes

- 6a6c7c14e: Filter the headers that are sent from the proxied-targed back to the frontend to not forwarded unwanted authentication or
  monitoring contexts from other origins (like `Set-Cookie` with e.g. a google analytics context). The implementation reuses
  the `allowedHeaders` configuration that now controls both directions `frontend->target` and `target->frontend`.

### Minor Changes

- 5249594c5: Add service discovery interface and implement for single host deployments

  Fixes #1847, #2596

  Went with an interface similar to the frontend DiscoveryApi, since it's dead simple but still provides a lot of flexibility in the implementation.

  Also ended up with two different methods, one for internal endpoint discovery and one for external. The two use-cases are explained a bit more in the docs, but basically it's service-to-service vs callback URLs.

  This did get me thinking about uniqueness and that we're heading towards a global namespace for backend plugin IDs. That's probably fine, but if we're happy with that we should leverage it a bit more to simplify the backend setup. For example we'd have each plugin provide its own ID and not manually mount on paths in the backend.

  Draft until we're happy with the implementation, then I can add more docs and changelog entry. Also didn't go on a thorough hunt for places where discovery can be used, but I don't think there are many since it's been pretty awkward to do service-to-service communication.

- 9226c2aaa: Limit the http headers that are forwarded from the request to a safe set of defaults.
  A user can configure additional headers that should be forwarded if the specific applications needs that.

  ```yaml
  proxy:
    '/my-api':
      target: 'https://my-api.com/get'
      allowedHeaders:
        # We need to forward the Authorization header that was provided by the caller
        - Authorization
  ```
