The sails-hello-world program

The program workspace includes the following packages:

• sails-hello-world is the package allowing to build WASM binary for the program and IDL file for it.
  The package also includes integration tests for the program in the tests sub-folder
• sails-hello-world-app is the package containing business logic for the program represented by the SailsHelloWorldService structure.
• sails-hello-world-client is the package containing the client for the program allowing to interact with it from another program, tests, or off-chain client.

Dev Environment setup

Install rust stable toolchain with wasm32-unknown-unknown toolchain and rust-src component, assuming you have rustup installed:

rustup default stable
rustup target add wasm32-unknown-unknown
rustup component add rust-src

Alternatively you can skip manually run the above commands if you have rust-toolchain.toml file in the root of the repository with the following content:

[toolchain]
channel = "stable"
targets = ["wasm32-unknown-unknown"]
components = ["rust-src"]
profile = "default"

Or you can simply open the repository in GitHub Codespaces by clicking the button below, which will automatically setup the dev environment for you:

Compile and test the program

Compile the program with the following command:

cargo build --release

After that, you will find the WASM binary in the ./target/wasm32-unknown-unknown/release sub-folder:

sails_hello_world.idl
sails_hello_world.opt.wasm
sails_hello_world.wasm

Run the unit tests and integration tests with the following command:

cargo test

Deploy the program
