# Envoy filter with Rust and WebAssembly

This is a demo accompanying a blogpost about building Envoy filters with Rust and WebAssembly.

## Getting started

1. Install WebAssembly target for rust

   ```sh

   $ rustup update

   $ rustup target add wasm32-unknown-unknown

   ```

2. Install [wasme](https://docs.solo.io/web-assembly-hub/latest/reference/cli/)

   ```sh

   $ curl -sL https://run.solo.io/wasme/install | sh

   $ export PATH=$HOME/.wasme/bin:$PATH

   ```

3. Clone the repo and use the makefile to build and run the demo:

   ```sh

   $ make build-image

   $ make deploy-envoy

   ```

Now you can open . This is proxying to , reflecting request headers back at you. You should see

```

"X-Hello": "Hello world from localhost:8080"

```

which was injected by the filter.
