# serverless-link-shortener
**A stateful serverless API built on top of AWS Lambda and Upstash Redis.**
## Special thanks to [Upstash](https://upstash.com/) for making projects like this possible!
## About:
The codebase consists of 2 functions:
- `new` to add links to the database, returns the shortened hash/code
- `get` to retrieve the links given the hash/code, returns HTML
## Code snippet:
```go
func Handler(ctx context.Context, request events.APIGatewayProxyRequest) (Response, error) {
// extract hash from API Gateway headers
hash := request.Headers["hash"]
// get from Redis compatible Upstash database
val, err := client.Get(ctx, hash).Result()
if err == redis.Nil {
// hash not found
return Response{
StatusCode: 404,
Body: notFoundResponse,
Headers: headers,
}, nil
}
// did find hash
return Response{
StatusCode: 200,
Body: fmt.Sprintf(redirectResponse, val),
Headers: headers,
}, nil
}
```
