examples

Examples need to be compiled to wasm components and published to the runtime.

Prerequisites

1. Rust: Latest stable version of the Rust programming language.
2. Thalo: Required for building aggregates to wasm.
   • Install with: cargo install thalo_cli
3. Thalo Runtime: Required for running the Thalo event sourcing environment.
   • Install with: cargo install thalo_runtime

Building & Running an Example

Aggregates need to be build to wasm components, and placed in the ./modules directory where thalo_runtime is started.

Start by building the counter example.

thalo build counter -o ./modules

The generated counter.wasm file will be placed in ./modules, and is read by thalo at startup.

Start thalo with cargo r -p thalo_runtime and you should see a log saying:

loaded module from file file="modules/counter.wasm"

This means thalo is ready to handle the Increment command defined in our counter module.

You can execute commands using the thalo_cli package:

cargo run -p thalo_cli -- execute Counter abc123 Increment '{"amount":10}'
