示例 Hello World DApp 技能

此技能可生成完整且可运行的 Midnight DApp，涵盖项目中的每个文件：Compact 合约、TypeScript 工具、测试脚本、Docker 配置和软件包设置。所有代码均与官方 midnightntwrk/example-hello-world 参考实现一致。

主要参考资料：

• github.com/midnightntwrk/example-hello-world — 官方参考仓库
• docs.midnight.network/getting-started/hello-world — 官方 Hello World 指南
• docs.midnight.network/relnotes/support-matrix — 权威版本兼容性矩阵

以下软件包版本是截至 2026 年 5 月的快照。 固定版本前，请从支持矩阵中确认当前经过测试的版本组合，另请参阅 references/volatile.md。切勿安装 @latest。

关键架构说明：

• 使用 @midnight-ntwrk/testkit-js 的 FluentWalletBuilder 创建钱包
• 使用 @midnight-ntwrk/midnight-js-contracts 的 deployContract 和 submitCallTx
• Compact pragma 为 >= 0.23
• 本地 devnet 的索引器 API 路径使用 /api/v4/graphql
• MidnightWalletProvider 类封装 WalletFacade，以实现 MidnightProvider 和 WalletProvider 接口
• syncWallet 函数会在钱包同步期间提供详细的进度日志
• 测试使用静态种子（ALICE_SEED），以实现可复现的测试
• privateStateStoreName 使用 Date.now() 实现测试隔离
• 使用 ESM 的 vitest 需要 NODE_OPTIONS='--experimental-vm-modules'

contracts/managed/ 目录由 Compact 编译器创建 — 请勿手动创建或编辑其中的文件。

4) tsconfig.json

{
  "compilerOptions": {
    "target": "ES2022",
    "module": "ES2022",
    "moduleResolution": "bundler",
    "lib": ["ES2022"],
    "strict": true,
    "esModuleInterop": true,
    "skipLibCheck": true,
    "forceConsistentCasingInFileNames": true,
    "resolveJsonModule": true,
    "isolatedModules": true,
    "verbatimModuleSyntax": true,
    "noEmit": true,
    "outDir": "dist",
    "rootDir": "."
  },
  "include": ["src/**/*.ts", "contract/**/*.ts"]
}

⚠️ "contract/**/*.ts" 使用单数形式 — 这与仓库完全一致，并涵盖编译器的输出路径。使用复数形式的 "contracts/**/*.ts" 会导致 TypeScript 无提示地无法解析编译后的合约类型。

---

5) vitest.config.ts

import { defineConfig } from 'vitest/config';

export default defineConfig({
  test: {
    environment: 'node',
    globals: true,
    testTimeout: 10 * 60_000,
    hookTimeout: 15 * 60_000,
    include: ['src/**/*.test.ts'],
    reporters: ['default'],
    sequence: { concurrent: false },
  },
});

---

6) contracts/hello-world.compact

请手动创建此文件 — managed/ 中的编译器输出由此文件生成。

pragma language_version >= 0.23;

export ledger message: Opaque<"string">;

export circuit storeMessage(newMessage: Opaque<"string">): [] {
  message = disclose(newMessage);
}

请从 contracts/ 目录进行编译：

cd contracts
compact compile hello-world.compact managed/hello-world
cd ..

预期输出：

Compiling 1 circuits:
  circuit "storeMessage" (k=6, rows=26)

这会生成 contracts/managed/hello-world/contract/index.js（以及密钥、zkir 和编译器目录）。运行测试前请务必先进行编译。

---

7) contracts/index.ts（barrel 文件 — 手动创建）

请手动创建此文件 — 它会从编译后的合约输出中导入内容。必须先运行 compact compile，生成已编译的合约模块，导入才能成功解析。

import { CompiledContract } from '@midnight-ntwrk/compact-runtime';
import { fileURLToPath } from 'node:url';
import path from 'node:path';

export {
  Contract,
  ledger,
  pureCircuits,
  type Ledger,
  type ImpureCircuits,
  type PureCircuits,
} from './managed/hello-world/contract/index.js';
import { Contract } from './managed/hello-world/contract/index.js';

const currentDir = path.dirname(fileURLToPath(import.meta.url));
export const zkConfigPath = path.resolve(currentDir, 'managed', 'hello-world');

export const CompiledHelloWorldContract = CompiledContract.make(
  'HelloWorldContract',
  Contract,
).pipe(
  CompiledContract.withVacantWitnesses,
  CompiledContract.withCompiledFileAssets(zkConfigPath),
);

---

8) src/config.ts

export type NetworkConfig = {
  networkId: string;
  indexer: string;
  indexerWS: string;
  node: string;
  nodeWS: string;
  proofServer: string;
  faucet: string;
};

export const LOCAL_CONFIG: NetworkConfig = {
  networkId: 'undeployed',
  indexer: 'http://127.0.0.1:8088/api/v4/graphql',

};

  if (network !== 'local') {

# 3. Start local stack
yarn env:up
# wait ~30 seconds for all services to become healthy

# 4. Run tests (new terminal)
yarn test:local

14) 故障排查

错误	原因	修复方法
compact: command not found	未设置 PATH	source $HOME/.local/bin/env
Cannot find module '../../contracts/...'	尚未编译合约	先在 contracts/ 目录中运行 compact compile
ETARGET No matching version found	版本不在经过测试的集合中	根据支持矩阵确定当前版本 — 参见 references/volatile.md。不要安装 @latest。
ECONNREFUSED 127.0.0.1:6300	证明服务未运行	yarn env:up
测试中出现 NODE_OPTIONS 错误	缺少实验性标志	确保在测试脚本中设置了 NODE_OPTIONS='--experimental-vm-modules'
Wallet sync timeout	Docker 服务未正常运行	确认 yarn env:up 已完成 — 所有 3 个容器都必须处于正常状态
v4/graphql 返回 404	索引器 URL 已过时	本地 devnet 使用 /api/v4/graphql — 在 config.ts 中修正
FluentWalletBuilder is not a function	导入的 testkit-js 不正确	从 @midnight-ntwrk/testkit-js 导入
levelPrivateStateProvider 选项错误	缺少必需字段	必须传入 privateStateStoreName、walletProvider、privateStoragePasswordProvider（强密码，至少 16 个字符，且不能包含连续字符模式）以及 accountId
TS：合约的 Cannot find module	tsconfig.json 的 include 不正确	必须使用 "contract/**/*.ts"（单数），而不是 "contracts/**/*.ts"
找不到 submitCallTx	导入错误	从 @midnight-ntwrk/midnight-js-contracts 导入
重新编译后旧合约地址失效	验证密钥已更改	重新部署 — 合约源码更改时，编译后的密钥也会改变

15) 改造此模板

1. 将 contracts/hello-world.compact 替换为你的合约
2. 编译：cd contracts && compact compile your-contract.compact managed/your-contract
3. 更新 contracts/index.ts：
   • 将导入路径改为 ./managed/your-contract/contract/index.js
   • 将 zkConfigPath 更新为 managed/your-contract
   • 更新 CompiledContract.make() 名称和 Contract 引用
4. 在 src/providers.ts 中：
   • 将 HelloWorldCircuits 类型更新为你的电路名称
   • 更新 privateStateStoreName 前缀，避免 LevelDB 冲突
5. 在 src/test/hw.test.ts 中：
   • 将 submitCallTx 参数替换为你的电路调用
   • 将 ledger() 替换为合约的 ledger() 函数
   • 更新 ALICE_PRIVATE_STATE_ID 和 initialPrivateState 的结构
6. 如果目标网络不是本地网络，则更新 src/config.ts
