Now, the Moesif plugin wants to run some Lua on outgoing requests. The EnvoyFilter documentation has a clear way to do that; it's a somewhat typical use case. However, there's a problem — the Lua it wants to run depends on the Moesif library. This use case is closer to embedded Lua than a full-fledged application with a package manager. We will use emscripten to compile Lua in this case. First of all, we will need to obtain the emscripten package. It is super easy to do on macOS. brew install emscripten. Then follow the instruction to set up emcc. Since we are going to host Lua in the browser environment.
