Ethereum Smart Contracts Interface Generator

NPM command that generates an interface from ABIs to interact with the Ethereum smart contracts.

IMPORTANT: this package is still under development!

The generated interface is easily customizable: the GUI is built with bootstrap and vanilla javascript (and of course Web3.js 🙂).

With this NPM command you can export the interface or run the interface automatically on the server.

---

Installation

npm i ethereum-interface-generator -g

Commands

Serve

The serve command creates the interface for interacting with the smart contract and it starts the server to the default URL http://localhost:5432.

Usage:

eth-ui-gen serve

Options:

• -c (or --contracts): folder that contains the compiled ABI of the smart contracts. Default: current folder (.);
• -p (or --port): port of the local server. Default: 5432

Note: if you run eth-ui-gen serve without specifying -c then make sure you run the command in the same folder where the ABIs are stored (on Truffle the folder is build/contracts).

The command below builds the interface using the ABIs found in the folder /../dapp/build/contracts/ and then it starts the local server on the port 7765.

eth-ui-gen serve -c /../dapp/build/contracts/ -p 7765

Export

eth-ui-gen export

Options:

• -c (or --contracts): folder that contains the compiled ABI of the smart contracts. Default: current folder (.);
• -t (or --target): destination folder where to export the files. Default: current folder (.).
• -m (or --minify): minify the Javascript. Default: false.

Note: if you run eth-ui-gen export without specifying -c then make sure you run the command in the same folder where the ABIs are stored (on Truffle the folder is build/contracts).

The command below builds the UI using the smart contract ABIs found in the folder /../dapp/build/contracts/ and it exports the files to the folder /home/dan/Desktop/smart-contracts-ui/.

eth-ui-gen export -c /../dapp/build/contracts/ -t /home/dan/Desktop/smart-contracts-ui/

Smart Contract JSON Format

The JSON files of the compiled and deployed smart contracts (that you give to the command) must contain the following values:

• contractName: the name of the contract.
• abi: ABI of the compiled smart contract.
• networks: list of networks where the contract has been deployed.

Below an example of how the JSON file should look like:

{
    "contractName": "MyAwesomeContract",
    "abi": [
        {
        "inputs": [
            {
                "internalType": "string",
                "name": "name",
                "type": "string"
            }
        ],
        "name": "storeName",
        "outputs": [],
        "stateMutability": "payable",
        "type": "function",
        "payable": true
        },

        ...

    ],
    "networks": {
        "4747": {
            "events": {},
            "links": {},
            "address": "0xba607E0A4eED20239C4f2237688e660da8262e3E",
            "transactionHash": "0x9bc44b20869b2ed0bf62788da9fe65fe847a5cf37225bc5e442c4d4319e10f29"
        }
    }
