Generate Solidity Files using React TypeScript

ReadMe.md

Create a project in React that enables users to generate Solidity smart contracts without writing code, you can follow these steps:

Define Function Templates:

Create predefined function templates for common operations in Solidity, like minting tokens, transferring ownership, etc. Use TypeScript to ensure type safety in your code.

UI Components:

Develop React components for users to select predefined functions and set parameters. Utilize state management (e.g., React hooks) to manage user input.

Code Generation:

Write TypeScript code to dynamically generate Solidity code based on user inputs and selected function templates. Utilize string templating or code generation libraries to create Solidity code snippets. File Creation:

Implement functionality to save the generated Solidity code as a .sol file. Use TypeScript to manage file creation and interactions.

For ERC721 specifically:

ERC721 Function Templates:

Include function templates for ERC721-specific actions such as minting tokens, transferring ownership, and querying token details.

Token Metadata:

Implement a mechanism for users to input token metadata, which is essential for ERC721 contracts.

Solidity Code Generation:

Based on the selected ERC721 functions and user input, generate Solidity code that adheres to the ERC721 standard.

File Creation and Download:

Enable users to download the generated Solidity code as a .sol file for deployment. Ensure your React components have clear documentation, and consider using a code editor or a code preview feature to allow users to visualize the generated Solidity code.

Remember to keep your code modular and well-organized to handle potential future updates or additional features.

ContractBuilder.tsx

import React, { useState } from 'react';
import { FunctionTemplate, mintFunction, pauseFunction, unpauseFunction } from './functions';

const ContractBuilder: React.FC = () => {
  const [selectedFunction, setSelectedFunction] = useState<FunctionTemplate | null>(null);
  const [functionParams, setFunctionParams] = useState<Record<string, any>>({});

  const functionTemplates = [mintFunction, pauseFunction, unpauseFunction];

  const handleFunctionSelection = (func: FunctionTemplate) => {
    setSelectedFunction(func);
    setFunctionParams({}); // Reset params
  };

  const handleParamChange = (param: string, value: any) => {
    setFunctionParams((prevParams) => ({ ...prevParams, [param]: value }));
  };

  const generateCode = () => {
    if (!selectedFunction) return '';
    return selectedFunction.generateCode(functionParams);
  };

  return (
    <div>
      {/* Render UI for function selection, parameters, and code preview */}
      <div>
        {functionTemplates.map((func) => (
          <button key={func.name} onClick={() => handleFunctionSelection(func)}>
            {func.name}
          </button>
        ))}
      </div>

      {/* Render UI for parameter inputs based on selected function */}
      {selectedFunction && (
        <>
          {selectedFunction.parameters.map((param) => (
            <input
              key={param}
              type="text"
              placeholder={param}
              value={functionParams[param] || ''}
              onChange={(e) => handleParamChange(param, e.target.value)}
            />
          ))}
        </>
      )}

      {/* Render code preview */}
      <pre>{generateCode()}</pre>
    </div>

    }`,
