A very simple proxy that can be extensible with wasm components
The proxy defines an interface to be implemented by wasm components.
This interface corresponds to handlers to events raised by the proxy.
For now the only event is page-viewed which receives the URL of the page as payload.
Event processing is done concurrently to add as little overhead as possible to the forwarding of the content.
Make sure that you allow direnv to load the Nix environment (direnv allow) or run nix develop manually.
build-component
This will build the amplitude component. It can be found in target/wasm32-wasi/release/amplited.wasm.
run-proxy
The proxy will be listening on port 8080.
To see the proxy working use this command
http -v --proxy=http:http://localhost:8080 lemonde.edgee.dev
This has a similar effect as adding lemonde.edgee.dev 127.0.0.1 to your /etc/hosts file.
This request will match the configuration of the proxy and will be redirected.
The component implementation just prints the viewed URL.
