+# vapor-lambda-runtime
+
+Run your Vapor app on AWS Lambda. This package bridges the communication between [`swift-lambda-runtime`](https://github.com/fabianfett/swift-aws-lambda)
+and the [vapor](https://github.com/vapor/vapor) framework. APIGateway requests are transformed into `Vapor.Request`s and `Vapor.Response`s are written back to the APIGateway.
+
+This project is intended to be run using the [Swift Layer from the amazonlinux-swift project](https://fabianfett.de/amazonlinux-swift).
+
+## Status
+
+**Note: Currently this is nothing more than a proof of concept. Use at your own risk. I would like to hear feedback, if you played with this. Please open a GitHub issues for all open ends, you experience.**
+
+What I have tested:
+
+- [x] Routing
+- [x] JSON Coding
+- [x] Cors Middleware
+- [ ] Fluent
+- There are probably tons of other things that we should test. I haven't been a Vpor developer so far, so you will need to help me list the things to test.
+
+Examples:
+- [HelloWorld](examples/Hello/Sources/Hello/main.swift)
+- [Super simple TodoBackend](examples/VaporTodoLambda/Sources/VaporTodoLambda/main.swift) example with DynamoDB backend (terrible code) using aws-sdk-swift
+
+If you test anything, please open a PR so that we can document the state of afairs better. A super small example would be even better. I plan to create some integration tests with the examples.
+
+## Usage
+
+Add `vapor-lambda-runtime` and `vapor` as dependencies to your project. For 
+this open your `Package.swift`:
+
+```swift
+  dependencies: [
+    .package(url: "https://github.com/vapor/vapor.git", from: "4.0.0-beta.3.1"),
+    .package(url: "https://github.com/fabianfett/vapor-lambda-runtime", .upToNextMajor(from: "0.1.0")),
+  ]
+```
+
+Add VaporLambdaRuntime as depency to your target:
+
+```swift
+  targets: [
+    .target(name: "Hello", dependencies: ["Vapor", "VaporLambdaRuntime"]),
+  ]
+```
+
+Create a simple Vapor app.
+
+```swift
+import Vapor
+import VaporLambdaRuntime
+
+let app = Application()
+defer { app.shutdown() }
+
+struct Name: Codable {
+  let name: String
+}
+
+struct Hello: Content {
+  let hello: String
+}
+
+app.get("hello") { (req) -> Hello in
+  return Hello(hello: "world")
+}
+
+app.post("hello") { req -> Hello in
+  let name = try req.content.decode(Name.self)
+  return Hello(hello: name.name)
+}
+```
+
+Now we just need to run the vapor app. To enable running in Lambda, we 
+need to change the "serve" command. Then we can start the app by calling
+`app.run()`
+
+```swift
+app.commands.use(LambdaCommand(), as: "serve", isDefault: true)
+
+try app.run()
+```
+
+## Contributing
+
+Please feel welcome and encouraged to contribute to vapor-lambda-runtime. The current version has a long way to go before being ready for production use and help is always welcome.
+
+If you've found a bug, have a suggestion or need help getting started, please open an Issue or a PR. If you use this package, I'd be grateful for sharing your experience.
+
+If you like this project, I'm excited about GitHub stars. 🤓
