This directory holds runnable demos for LambdaKit. Each example is an executable target declared at the root of Package.swift, so you can build or run any of them with swift run <target>.

• TrailLog — swift run TrailLogDemo
  A complete Lambda-shaped service using both libraries together. Sets up an HTTP router, registers routes through middleware, and uses DynamoQueries for reads and writes. Models a hike-logging app: hikers record completed hikes against named trails, with elevation, distance, and rating per hike.

• RoutingDemo — swift run RoutingDemo
  A focused demo of the Routing library wired up to the AWS Lambda transport types. Registers a small trail-log API on HTTPRouterBuilder, composes a LoggingMiddleware + AuthMiddleware chain, and dispatches synthetic APIGatewayV2Request events through the router so you can see the middleware flow without spinning up a Lambda.

• DynamoQueriesDemo — swift run DynamoQueriesDemo
  A focused demo of the DynamoQueries library. Walks through the major operations against an in-memory DynamoClient mock: query, scan, put-if-not-exists, optimistic-concurrency update, batch write, and transact write.

The demos all run locally — none of them require AWS credentials. Where a DynamoClient is needed, the focused demos use a recording mock; the TrailLog demo wires up a SotoDynamoClient against a localhost DynamoDB endpoint (point at DynamoDB Local to actually exercise it).
