Counter App

This is an example project to show how the contract-version library can be used. Please check that library for more details.

This contract has an internal counter that can be incremented, and also has a view method to show information gathered at compile-time.

Live Testing

Download and extract the latest release, dev-deploy the example_counter.wasm and then near view the version method.

Alternatively, you can use a live contract:

near view "dev-1644939364756-75367548411779" "version"

output:

Build

Build the wasm binary:

cargo build --release --target wasm32-unknown-unknown

Test

After having built the wasm binary, copy them to the res/ directory:

find target/wasm32-unknown-unknown/release \
    -maxdepth 1 \
    -name \*.wasm \
    -prune \
    -exec cp {} res \;

Then run the simulation tests:

cargo test
