+# worker-template-tinygo
+
+- A template for starting a Cloudflare Worker project with tinygo.
+- This template uses [`workers`](https://github.com/syumai/workers) package to run an HTTP server.
+
+## Usage
+
+- `main.go` includes simple HTTP server implementation. Feel free to edit this code and implement your own HTTP server.
+
+## Requirements
+
+- Node.js
+- [wrangler](https://developers.cloudflare.com/workers/wrangler/)
+  - just run `npm install -g wrangler`
+- tinygo
+
+## Getting Started
+
+```
+$ wrangler generate my-app syumai/workers/_templates/cloudflare/worker-tinygo
+$ cd my-app
+$ go mod init
+$ go mod tidy
+$ make dev # start running dev server
+$ curl http://localhost:8787/hello
+Hello!
+```
+
+- To change worker name, please edit `name` property in `wrangler.toml`.
+
+## Development
+
+### Commands
+
+```
+make dev     # run dev server
+make build   # build Go Wasm binary
+make publish # publish worker
+```
+
+### Testing dev server
+
+- Just send HTTP request using some tools like curl.
+
+```
+$ curl http://localhost:8787/hello
+Hello!
+```
+
+```
+$ curl -X POST -d "test message" http://localhost:8787/echo
+test message
+```
