Install the package from npm:

npm install chia-condition-codes

After installation, you can import the enum into your project:

const { ConditionCodes } = require('chia-condition-codes');

OR

import { ConditionCodes } from 'chia-condition-codes';

Use the enum in your code like so:

const solution = Program.fromSource(`(${ConditionCodes.CREATE_COIN} 300000 (${hint} ${memos.join(" ")}))`);

The package exports an enumeration of various conditions used in the Chia blockchain. Each condition represents a specific rule or requirement in Chia's smart contract programming:

• AGG_SIG_AMOUNT: Verifies a signature with the amount of the coin.
• AGG_SIG_PUZZLE_AMOUNT: Signature verification with puzzle hash and amount.
• AGG_SIG_PARENT_AMOUNT: Signature verification with parent coin id and amount.
• AGG_SIG_PARENT_PUZZLE: Signature verification with parent coin id and puzzle hash.
• AGG_SIG_UNSAFE: Basic signature verification without domain strings.
• AGG_SIG_ME: Verifies a signature with the coin id.
