CWAO Tools

cwao-tools makes CosmWasm contract development & testing too easy.

Quick Start

Make sure you have, NodeJS v18 or above, Rust/Cargo, and wasm32-unknown-unknown installed on your computer.

Install

sudo npm install -g cwao-tools

This will install cwao command globally.

Create Project

cwao create myapp

Test

yarn test compiles the Rust contracts in contracts, and run the tests in test.

cd myapp
yarn test

You can use the test boilerplate at test/test.js.
Everything will be set up before the tests and you can use cw object to interact with the contracts.

• i: instantiate
• e: execute
• q: query

const { expect } = require("chai")
const { start } = require("./utils")

describe("CWAO", function () {
  this.timeout(0)
  let stop, cw
  before(async () => ({ stop, cw } = await start()))
  after(async () => await stop())

  it("should execute queries", async () => {
    await cw.i({ num: 3 })
    expect(await cw.q("Num")).to.eql({ num: 3 })
    await cw.e("Add", { num: 1 })
    expect(await cw.q("Num")).to.eql({ num: 4 })
  })
})

Deploy Contract

To deploy the contract, run Arweave testnet and AO units on your local machine first.

yarn start

3 wallets (mu / su / cu) were generated.

Then, deploy the contract as an AO module. You can generate a new wallet with --wallet.

yarn deploy --wallet acc # returns MODULE_ID

Also, set up a scheduler address. Use --wallet su.

yarn setSU --wallet su # returns SCHEDULER_ADDRESS

Finally, instantiate the contract as an AO process.

yarn instantiate --wallet acc --module_id MODULE_ID --scheduler SCHEDULER_ADDRESS --input '{ "num": 3 }'

Now you got a PROCESS_ID.

const { CWAO } = require("cwao")
const wallet = ARWEAVE_WALLET_JWK
const cw = new CWAO({ wallet }).cw({ process: PROCESS_ID })
await cw.e("Add", { num: 1 })
await cw.q("Num") // { num: 4 }
