Usage

Here is an example of how you can set up and use Microcraft Lib:

// Initializing the app JSON
const app = {
  components: [
    {
      "type": "text",
      "label": "Enter ERC20 Address",
      "id": "erc20AddressInput",
      "placement": "input"
    },
    {
      "type": "button",
      "label": "Fetch ERC20 Data",
      "id": "fetchERC20Data",
      "placement": "action",
      "codeRef": "actions/fetch_token_details.js" // you can define a function that can fetch token details here
    },
    {
      "type": "text",
      "label": "Total ERC20 Supply",
      "id": "erc20TotalSupply",
      "placement": "output"
    },
    {
      "type": "text",
      "label": "ERC20 Token Name",
      "id": "erc20Name",
      "placement": "output"
    },
    {
      "type": "text",
      "label": "ERC20 Token Symbol",
      "id": "erc20Symbol",
      "placement": "output"
    },
    {
      "type": "walletDropdown",
      "label": "Select Connected Wallet Address",
      "id": "walletAddress",
      "options": [],
      "placement": "input"
    },
    {
      "type": "text",
      "label": "Or Enter Wallet Address",
      "id": "walletAddressInput",
      "placement": "input"
    },
    {
      "type": "button",
      "label": "Fetch Wallet Data",
      "id": "fetchWalletInfo",
      "placement": "action",
      "codeRef": "actions/fetch_wallet.js"
    },
    {
      "type": "text",
      "label": "User's ERC20 Balance",
      "id": "erc20UserBalance",
      "placement": "output"
    }
  ],
  contracts: [
    {
      "name": "ERC20",
      "address": "0x5f98805A4E8be255a32880FDeC7F6728C6568bA0",
      "template": "ERC20",
      "abi": []
    }
  ],
  networks: [
    {
      "type": "ethereum",
      "config": {
        "rpcUrl": "your_rpc_url",
        "chainId": "your_chain_id",
        "exploreUrl": "your_explore_url"
      }
    },
    {
      "type": "cosmos",
      "config": {
        "rpcUrl": "your_cosmos_rpc_url",
        "chainId": "your_cosmos_chain_id",
        "exploreUrl": "your_cosmos_explore_url"
      }
    }
  ]
}

// Initial data for app elements(components)
let data = {};

// Callback function to handle data updates
function setDataCallback(newData) {
  data = { ...data, ...newData };
}

// Debugging
const [outputCode, setOutputCode] = useState<Output | string>();

// Rendering the DynamicApp component
<DynamicApp
  components={app.components}
  data={data}
  setData={setDataCallback}
  contracts={app.contracts}
  networks={app.networks}
  debug={setOutputCode}
/>

Example Explained

• Components: Defined as an array, each component has a type (e.g., "text", "button", "walletDropdown"), a label, an ID, and a placement that specifies its role (e.g., input, action, output).
• Contract Details: Includes details like the contract name, address, template, and ABI for smart contract interaction.
• Network Details: Configures the network type and RPC, chain ID, and explorer URL for connection.

You can render the UI dynamically using the <DynamicApp /> component, which takes in the components, data, contracts, and networks details. The app also supports a debug function to monitor output data.
