+# TypeScript support for Winglang
+
+> TODO
+
+## Prerequisites
+
+* [winglang](https://winglang.io).
+
+## Installation
+
+`sh
+npm i @winglibs/typescript
+`
+
+## Usage
+
+The `FunctionHandler`, `QueueHandler` and `ApiEndpointHandler` types can be used to define inflight
+handlers from a TypeScript codebase.
+
+For example:
+
+```ts
+// src/index.ts
+exports.handler = async (event, context) => {
+  console.log("Welcome to TypeScript", event);
+  return {
+    status: 200,
+    body: JSON.stringify({ message: "Hello, TypeScript" }),
+  };
+};
+```
+
+```js
+// main.w
+bring typescript;
+
+new cloud.Function(new typescript.FunctionHandler("./src"));
+```
+
+## TODO
+
+- [ ] README
+- [ ] Tests
+- [ ] Hot reloading
+- [ ] Interact with cloud resources from the typescript side
+
+Workarounds:
+
+* https://github.com/winglang/wing/issues/5476
+* `queue.setConsumerFunction`
+* `cloud.Api()` with `TypeScriptFunction`
+* `__dirname` to reference `src`
+* `patchToInflight`
+
