This variation of "Hello, world!" is written in Rust.
ICP Ninja is a web-based integrated development environment (IDE) for the Internet Computer. It allows you to write code and deploy applications directly from your web browser in a temporary, sandbox-like environment.
For users who may already be familiar with the Internet Computer or who would rather use more advanced tooling such as command-line development tools, please refer to the ICP developer documentation to learn more.
Projects deployed to ICP from ICP Ninja are available on the mainnet for 20 minutes at a time. After 20 minutes, the project must be redeployed.
To deploy your project for long-term, production use such that it persists longer than 20 minutes without needing to be redeployed, you must migrate the files off of ICP Ninja and deploy them to the mainnet via dfx in a command-line environment.
The /backend folder contains the Rust smart contract:
Cargo.toml, which defines the crate that will form the backendlib.rs, which contains the actual smart contract, and exports its interface
The /frontend folder contains web assets for the application's user interface. The user interface is written with plain JavaScript, but any frontend framework can be used.
