@0xweb/hardhat NPM

`0xweb` plugin for Hardhat

The plugin generates 0xWeb classes for compiled solidity contracts, making the blockchain development transparent.

We use 📦 dequanto library for the classes

Documentation 📜

Install

Install automatically the dependencies and configurations

# install 0xweb
$ npm i 0xweb -g

# initialize 0xweb and hardhat project
$ 0xweb init --hardhat

Compile

any/directory/Foo.sol

pragma solidity ^0.8.2;

contract Foo {
    string public name;

    function setName(string memory _name) public {
        name = _name;
    }
}

Plugin adds also ability to specify the sources folder. As per default this is /contracts/**.sol

$ npx hardhat compile --sources ./any/directory/

Use in local development

example.ts

import { Foo } from '0xc/hardhat/Foo/Foo.ts'
import { HardhatProvider } from '@dequanto/hardhat/HardhatProvider'

// automatically deploys the contract to hardhat chain const deployer = new HardhatProvider(); const foo = await deployer.deployClass(Foo, { arguments: 'Hello' });

// write const tx = await foo.setName('Hello world') const receipt = await tx.wait();

// read const text = await foo.name();

# Use already deployed contracts to any chain

If the contract is already deployed, initialize the contract with the Address as normal class. If the contract is deployed to any other chain - set also the client in constructor

> `example.ts`
```ts
import { Foo } from '0xc/hardhat/Foo/Foo.ts'
import { EthWeb3Client } from '@dequanto/clients/EthWeb3Client'


const client =  new EthWeb3Client();
const foo = new Foo('0x12345...', client);

// write
const tx = await foo.setName('Hello world');
const receipt = tx.wait();
// read
const text = await foo.name();

Additional parameters

npx hardhat compile --sources /foo/bar/qux - compiles solidity files which are located outside the /contracts folder
npx hardhat compile --artifacts /dist - set custom folder for artifacts (ABI JSONs and TS contracts)
npx hardhat compile --watch - Compile the sources and waits to recompile on changes
npx hardhat compile --tsgen false - Do not generate the TS classes
npx hardhat compile --package path/to/package/folder - You can split your project into packages, and with the command compile the contracts in a package, the sources will be searched in that directory, and the artifacts output will be written to that directory
