# Entity Feedback Backend

Welcome to the entity-feedback backend plugin!

## Installation

### Install the package

```bash
# From your Backstage root directory
yarn add --cwd packages/backend @backstage/plugin-entity-feedback-backend
```

### Adding the plugin to your `packages/backend`

You'll need to add the plugin to the router in your `backend` package. You can do this by creating a file called `packages/backend/src/plugins/entityFeedback.ts`

```tsx
import { createRouter } from '@backstage/plugin-entity-feedback-backend';
import { Router } from 'express';
import { PluginEnvironment } from '../types';

export default function createPlugin(env: PluginEnvironment): Promise<Router> {
  return createRouter({
    database: env.database,
    discovery: env.discovery,
    identity: env.identity,
    logger: env.logger,
  });
}
```

With the `entityFeedback.ts` router setup in place, add the router to `packages/backend/src/index.ts`:

```diff
+import entityFeedback from './plugins/entityFeedback';

async function main() {
  ...
  const createEnv = makeCreateEnv(config);

  const catalogEnv = useHotMemoize(module, () => createEnv('catalog'));
+ const entityFeedbackEnv = useHotMemoize(module, () => createEnv('entityFeedback'));

  const apiRouter = Router();
+ apiRouter.use('/entity-feedback', await entityFeedback(entityFeedbackEnv));
  ...
  apiRouter.use(notFoundHandler());

```

### New Backend System

The Entity Feedback backend plugin has support for the [new backend system](https://backstage.io/docs/backend-system/), here's how you can set that up:
In your `packages/backend/src/index.ts` make the following changes:

```diff
+ import { entityFeedbackPlugin } from '@backstage/plugin-entity-feedback-backend';

const backend = createBackend();
+ backend.add(entityFeedbackPlugin());
// ... other feature additions

backend.start();
```
