:: Proxy server
:: ------------
::
:: This is a simple agent which accepts requests at the path given in the `on-init` arm-- in this
:: case, "/apps/uniswap-proxy/"-- and proxies them to the upstream, in this case,
:: "https://api.uniswap.org/".
::
:: For example, assuming your ship is running on `localhost:8080`, a request to the url
::
:: `http://localhost:8080/apps/uniswap-proxy/v1/graphql`
::
:: will be proxied to
::
