| 1 | +# Copilot Instructions for Ocean CLI |
| 2 | + |
| 3 | +## Project Overview |
| 4 | + |
| 5 | +Ocean CLI is a TypeScript-based command-line tool for interacting with Ocean Network, using Ocean Protocol's JavaScript library ([Ocean-Js](https://github.com/oceanprotocol/ocean.js)). It enables users to privately and securely publish, consume, and run compute operations. |
| 6 | + |
| 7 | +**Key Features:** |
| 8 | +- Publish data services (downloadable files or compute-to-data) |
| 9 | +- Edit existing assets |
| 10 | +- Consume data services and download data |
| 11 | +- Compute-to-data operations on public datasets |
| 12 | +- Manage access control with access lists |
| 13 | +- Handle escrow payments for compute jobs |
| 14 | +- Manage authentication with token generation |
| 15 | + |

| 41 | +## Code Style & Conventions |
| 42 | + |
| 43 | +### TypeScript Configuration |
| 44 | +- **Target:** ES2020 |
| 45 | +- **Module:** ES2020 |
| 46 | +- **Strict Mode:** Enabled |
| 47 | +- **Module Resolution:** Node |
| 48 | +- **Source Maps:** Enabled for debugging |
| 49 | + |
| 50 | +### Coding Standards |
| 51 | + |
| 52 | +1. **Imports & Exports:** |
| 53 | + - Use ES6 module syntax: `import`/`export` |
| 54 | + - Group imports: external libs, then internal modules |
| 55 | + - Use named imports when possible |
| 56 | + - Explicitly use `.js` extension for relative imports (ESM compatibility) |
| 57 | + |
| 58 | + ```typescript |
| 59 | + import { Command } from 'commander'; |
| 60 | + import { Commands } from './commands.js'; |
| 61 | + import chalk from 'chalk'; |
| 62 | + ``` |
| 63 | + |
| 64 | +2. **Formatting:** |
| 65 | + - Use Prettier for code formatting |
| 66 | + - Line length: Follow Prettier defaults |
| 67 | + - Indentation: 2 spaces |
| 68 | + - Semicolons: Always include |
| 69 | + - Quotes: Single quotes preferred |
| 70 | + |
| 71 | +3. **Naming Conventions:** |
| 72 | + - Classes/Types: PascalCase |
| 73 | + - Functions/Variables: camelCase |
| 74 | + - Constants: UPPER_SNAKE_CASE |
| 75 | + - Private methods: Prefix with `_` |
| 76 | + |
| 77 | +4. **Async/Await:** |
| 78 | + - Prefer async/await over Promise.then() |
| 79 | + - Use try/catch for error handling |
| 80 | + - Always return promises from async functions |
| 81 | + |
| 82 | +5. **Type Safety:** |
| 83 | + - Always provide explicit type annotations for function parameters and return types |
| 84 | + - Avoid `any` type; use `unknown` if necessary |
| 85 | + - Use interfaces for object types |
| 86 | + - Leverage TypeScript strict mode |
| 87 | + |
| 88 | + ```typescript |
| 89 | + async function initializeSigner(): Promise<{ signer: Signer; chainId: number }> { |
| 90 | + // implementation |
| 91 | + } |
| 92 | + ``` |
| 93 | + |
| 94 | +6. **Error Handling:** |
| 95 | + - Use chalk library for colored console output |
| 96 | + - Use `process.exit(code)` for CLI exit codes |
| 97 | + - Provide meaningful error messages to users |
| 98 | + |
| 99 | + ```typescript |
| 100 | + console.error(chalk.red("Error message")); |
| 101 | + process.exit(1); |
| 102 | + ``` |
| 103 | + |

| 182 | + |
| 183 | +## Best Practices |
| 184 | + |
| 185 | +1. **CLI Design:** |
| 186 | + - Use Commander.js for consistent command structure |
| 187 | + - Provide clear help text for all commands |
| 188 | + - Use interactive prompts for complex flows |
| 189 | + - Show progress for long-running operations |
| 190 | + |
| 191 | +2. **Wallet Management:** |
| 192 | + - Support both private key and mnemonic imports |
| 193 | + - Validate environment variables at startup |
| 194 | + - Use ethers.js for all cryptographic operations |
| 195 | + - Never log or expose private keys |
| 196 | + |
| 197 | +3. **Error Messages:** |
| 198 | + - Use `chalk.red()` for errors |
| 199 | + - Include actionable error messages |
| 200 | + - Exit with appropriate status codes (0 = success, 1 = error) |
| 201 | + |
| 202 | +4. **Code Organization:** |
| 203 | + - Keep CLI setup in `cli.ts` |
| 204 | + - Separate command logic into `commands.ts` |
| 205 | + - Share utilities in `helpers.ts` |
| 206 | + - Use modular flows for complex operations |
| 207 | + |
| 208 | +5. **Documentation:** |
| 209 | + - Include JSDoc comments for exported functions |
| 210 | + - Document complex algorithms and workflows |
| 211 | + - Keep README.md updated with usage examples |
| 212 | + |
| 213 | +## Common Patterns |
| 214 | + |
| 215 | +### Interactive Flows |
| 216 | +Use `readline/promises` for user input in interactive flows: |
| 217 | +```typescript |
| 218 | +import { createInterface } from 'readline/promises'; |
| 219 | +import { stdin as input, stdout as output } from 'node:process'; |
| 220 | + |
| 221 | +const rl = createInterface({ input, output }); |
| 222 | +const answer = await rl.question('Prompt: '); |
| 223 | +``` |
| 224 | + |
| 225 | +### Logging with Colors |
| 226 | +```typescript |
| 227 | +import chalk from 'chalk'; |
| 228 | + |
| 229 | +console.log(chalk.green('Success')); |
| 230 | +console.error(chalk.red('Error')); |
| 231 | +console.log(chalk.yellow('Warning')); |
| 232 | +console.log(chalk.blue('Info')); |
| 233 | +``` |
| 234 | + |
| 235 | +### Type-Safe Conversions |
| 236 | +```typescript |
| 237 | +import { toBoolean } from './helpers.js'; |
| 238 | +import { unitsToAmount } from '@oceanprotocol/lib'; |
| 239 | +``` |
| 240 | + |
