Using @taikai/dappkit with a custom contract

@taikai/dappkit exports Model class that needs an ABI structure as its constructor argument; It can be used to either extend and create a custom proxy by having transpiled the json or simply import the Model class and start using your compiled contract.

This can also be achieved by transpiling the custom contract and importing the newely created file, after optionally customizing the outputted code.

4. Use the transpiled custom contract

Without transpiling

Deploying the custom contract

import {Model} from '@taikai/dappkit';

const AlicePrivateKey = "aliceprivatekey";
const AliceCustomContract = "./AliceCustomContract.json";

const AliceCustomModel = new Model({web3Host: 'https://localhost:1337', privateKey: AlicePrivateKey}, AliceCustomContract.abi);

AliceCustomModel.web3Connection.start();
AliceCustomModel.loadAbi();

const tx = await AliceCustomModel.deploy({data: AliceCustomContract.bytecode, arguments: []}, AliceCustomModel.web3Connection.Account);

console.log('Contract deployed; Address: ', tx.contractAddress);

Using a custom contract

import {Model} from '@taikai/dappkit';

const AliceCustomModel = new Model({web3Host: 'https://localhost:1337', privateKey: AlicePrivateKey}, AliceCustomContract.abi, '0xCustomContractAddress');

AliceCustomModel.start();

// Get a value from the contract
const receipt = await AliceCustomModel.callTx(AliceCustomModel.contract.methods.CustomMethod('arg1'/*, 'otherArgument', ...etc */));
console.log(receipt);

// Change a value on the contract
const receipt2 = await AliceCustomModel.sendTx(AliceCustomModel.contract.methods.OtherCustomMethod('newValue'/*, 'otherArgument', ...etc */));
console.log(receipt2);
