-You can check out [examples](https://github.com/metrue/fx/tree/master/examples/functions) for reference. Let's write a function as an example,  it calculates the sum of two numbers then returns:

-```js

-    ctx.body = 'hello world'
-}
-```
-Then save it to a file `func.js`.

-3. Deploy your function as a service
-
-Give your service a port with `--port`, and name with `--name`, heath checking with `--healthcheck` if you want.
