  connectionString = await db.start();
  await db.applyMigrations("./netlify/database/migrations");
});

afterAll(async () => {
  await db.stop();
});

test("inserts and reads a user", async () => {
  const client = new Client({ connectionString });
  await client.connect();

  await client.query("INSERT INTO users (name) VALUES ($1)", ["Ada"]);
  const { rows } = await client.query("SELECT name FROM users");

```typescript
// example: await store.get('key-name');
    // - NEVER add the second arg unless you need an explicit type 'arrayBuffer' | 'blob' | 'json' | 'stream' | 'text'.

  X-Frame-Options: DENY
# another path:
/templates/index2.html
  # headers for that path:
  X-Frame-Options: SAMEORIGIN
```

--------------------------------

### Get Metadata Only Example

Source: https://docs.netlify.com/ai-context/netlify-development.mdc

Retrieves only the metadata of a blob without downloading the data. The second argument is for explicit types or etag checks. If the blob is missing, the promise resolves with null.

```typescript
// example: await store.getMetadata('key-name');
    // - NEVER add the second getOpts arg unless you need an explicit type or have an etag to check against.
    // - AVOID adding it unless it's reliably available but IF an etag is provided, it will only return the blob if the etag is different that what's stored.
```

--------------------------------

### Install and configure a build plugin

Source: https://docs.netlify.com/build/configure-builds/file-based-configuration

Add build plugins to your site by specifying the package name and any necessary inputs in the `[[plugins]]` section. This allows for extending build process functionality.

  breeds = ["pomeranian", "chihuahua", "bulldog"]
```

--------------------------------

### Get Blob with Metadata Example

Source: https://docs.netlify.com/ai-context/netlify-development.mdc

Retrieves a blob along with its metadata. The second argument should only be used for explicit types or etag checks. If the blob is missing, the promise resolves with null.

```typescript
// example: await store.getWithMetadata('key-name');
    // - NEVER add the second getOpts arg unless you need an explicit type or have an etag to check against.
    // - AVOID adding it unless it's reliably available but IF an etag is provided, it will only return the blob if the etag is different that what's stored.
```

    headers: {
      "Content-Type": "text/html",
    },
    body: "
    <!DOCTYPE html>

### Generate Edge Function for API Routes

Source: https://docs.netlify.com/build/frameworks/frameworks-api

```typescript
import type { Config, Context } from "@netlify/edge-functions";

export default async (req: Request, context: Context) => {
  if (req.headers.get("accept") === "application/json") {
    const { pathname } = new URL(req.url)

    return new URL(`/api${pathname}`, req.url)
  }
}

export const config: Config = {
  // Configures the paths on which the edge function runs.
  // The value below lets you intercept requests for any path.
  path: "/*",

  // Sometimes it's useful to exclude certain paths.
  // This example will ignore requests that are
  // already targeting an `/api/` path.
  excludedPath: ["/api/*"]
};
```

--------------------------------

### Example Build Command

```javascript
export const onPostBuild = async () => {
  const uploads = getDeployStore("file-uploads");
  const entry = await uploads.get("my-key");

  if (entry === null) {
    console.log("Could not find entry");
  } else {
    console.log(entry);
  }
};
```

--------------------------------

### Get blob data in an Edge Function

Source: https://docs.netlify.com/build/data-and-storage/netlify-blobs

```typescript
export default async (req: Request, context: Context) => {
  // Extract key from URL.
  const { key } = context.params;

  const uploads = getStore("file-uploads");
  const entry = await uploads.get(key);

  if (entry === null) {
    return new Response(`Could not find entry with key ${key}`, {
      status: 404
    });
  }

  return new Response(entry);
};
```
