This monorepo contains the source for the various components of the Serval mesh, intended to run on any host where you want to run WASM payloads. As of December 2022, this project is in very early stages of development and is changing rapidly.

The repo is a Rust workspace containing the following members:

• agent: a daemon that listens on a port for incoming HTTP requests with payloads to run
• cli: a command-line interface (called serval when built) for controlling the mesh and creating WASM jobs
• engine: a library for the wasmtime glue; in early stages
• queue: temporarily a separate service during MVP/demo period, this is manages the job queue for the Serval mesh. This functionality will eventually be integrated into the Serval agent.
• utils: a library for code we use in several places
• test-runner: a CLI to execute a WASM payload once, useful for developing the engine

This is a Rust project. If you do not have the rust compiler available, install it with rustup.

A justfile is provided for your convenience. It defines these recipes:

$ just -l
