Wasmify

Wasmify is a Wasm contract development environment. With this plugin you can scaffold a template smart contract app development and dramatically simplify the development and deployment process. Visualization support for contract deployment, contract interaction, contract query and contract migrate.

Installation

• Using IDE built-in plugin system:

  Settings/Preferences > Plugins > Marketplace > Search for "Wasmify" > Install Plugin

• Manually:

  Download the latest release and install it manually using Settings/Preferences > Plugins > ⚙️ > Install plugin from disk...

Initial setup

before creating out wasm project, we need to complete follow steps:

Install docker

For building and optimizing WASM smart contracts, we recommend to install docker on your personal computer.

we can download docker desktop from here, then following official install guideline to install it.

Setup Rust

While WASM smart contracts can be written in any programming language, it is strongly recommended that you utilize Rust, as it is the only language for which mature libraries and tooling exist for CosmWasm. To complete this tutorial, install the latest version of Rust by following the instructions here. Once Rust is installed on your computer, do the following:

1. Set the default release channel used to update Rust to stable.

rustup default stable

2. Add wasm as the compilation target.

rustup target add wasm32-unknown-unknown

Getting Start

Create a new project

The cosmwasm module is provided here, just choose to create a project from the contract template.

Add a signer

We need to create a signer to sign and pay gas fees for transactions, either by entering a private key or a mnemonic.

Add a network

Add a network on which we deploy contracts and invoke contracts. if you have no avaliable blockchain network, you can follow here to start a blockchain network for yourself.

Build project

You can click the run botton in the IDEA, then you will get the target file in the target directory.

Deploy a WasmContract

In the target directory, find the contract file ending with .wasm, then right-click on it alone and select DeployWasm.

Execute Contract

Open the Wasmify tool window, select the Contracts panel, then type Execute Msg and click the Execute button.

Query Contract

Open the Wasmify tool window, select the Contracts panel, then type Execute Msg and click the Query button.

Migrate Contract

To implement support for MigrateMsg, add the message to the msg.rs file. To do so, navigate to msg.rs and place the following code just above the InstantiateMsg struct.

#[cw_serde]
pub struct MigrateMsg {}

With MigrateMsg defined, update the contract.rs file. First, update the import from crate::msg to include MigrateMsg.

use crate::msg::{ExecuteMsg, GetCountResponse, InstantiateMsg, QueryMsg, MigrateMsg};

Next, add the following method above instantiate.

#[cfg_attr(not(feature = "library"), entry_point)]
pub fn migrate(_deps: DepsMut, _env: Env, _msg: MigrateMsg) -> StdResult<Response> {
    Ok(Response::default())
}

Rebuild Contract, click the run button. Finally, in the Wasmify tool window, select the constructed wasm file, type Msg, and click the Migrate button.

Plugin based on the IntelliJ Platform Plugin Template.
