Go-like Error Handling for TypeScript/JavaScript

\n\n

\n \"hero\"\n

\n\n> [!NOTE]\n>\n> unwrap-go brings Go-style error handling to TypeScript and JavaScript, offering a clean and predictable way to handle errors using Result tuples. This approach eliminates the need for try-catch blocks and provides a more functional approach to error management.\n\n## ๐ŸŒŸ Features\n\n> **unwrap-go** features intro:\n\n- **Go-Style Error Handling** โ€“ Uses tuple returns (`[data, error]`) similar to Go's approach, making error handling more explicit and predictable\n- **Promise Support** โ€“ Built-in support for handling asynchronous operations with the same elegant syntax\n- **Type Safety** โ€“ Full TypeScript support with generic types for both success and error cases\n- **Zero Dependencies** โ€“ Lightweight implementation with no external dependencies\n- **Synchronous Support** โ€“ Handle both async and sync operations with consistent patterns\n\n## ๐Ÿงจ Registries\n\n- **[jsr.io/@arnavk-09/unwrap-go](https://jsr.io/@arnavk-09/unwrap-go)**\n- **[npmjs.com/package/@arnavk-09/unwrap-go](https://www.npmjs.com/package/@arnavk-09/unwrap-go)**\n\n## ๐Ÿ’ป Installation\n\n> You can add **unwrap-go** with one command via:\n\n###### terminal\n\n```bash\nnpm install @arnavk-09/unwrap-go\ndeno add jsr:@arnavk-09/unwrap-go\nbun add @arnavk-09/unwrap-go\npnpm add @arnavk-09/unwrap-go\nyarn add @arnavk-09/unwrap-go\n\n```\n\n

OR

\n\n###### Deno\n\n```bash\ndeno add jsr:@arnavk-09/unwrap-go\n```\n\n###### Npx\n\n```bash\nnpm install @arnavk-09/unwrap-go\n```\n\n###### Bun\n\n```bash\nbun add @arnavk-09/unwrap-go\n```\n\n###### Pnpm\n\n```bash\npnpm add @arnavk-09/unwrap-go\n```\n\n###### Yarn\n\n```bash\nyarn add @arnavk-09/unwrap-go\n```\n\n## ๐Ÿš€ Usage\n\n```typescript\nimport { unwrapPromise, unwrapSync } from \"@arnavk-09/unwrap-go\";\n\n// Async example\nasync function fetchData() {\n const [data, err] = await unwrapPromise(\n fetch(\"https://api.example.com/data\"),\n );\n if (err) {\n console.error(\"Failed to fetch:\", err);\n return;\n }\n console.log(\"Data:\", data);\n}\n\n// Sync example\nfunction divide(a: number, b: number) {\n const [result, err] = unwrapSync(() => {\n if (b === 0) throw new Error(\"Division by zero\");\n return a / b;\n });\n if (err) {\n console.error(\"Division failed:\", err);\n return;\n }\n console.log(\"Result:\", result);\n}\n```\n\n## ๐Ÿ“š API Reference\n\n| Function | Description | Parameters | Return Type |\n| --------------------- | ---------------------------------------------------------- | ------------------------------------ | ------------------------ |\n| `unwrapPromise` | Wraps a promise to return a Result tuple | `promise: Promise` | `Promise>` |\n| `unwrapSync` | Executes a synchronous function and returns a Result tuple | `fn: () => T` | `Result` |\n| `Result` | Type representing either success (T) or error (E) | `T`: Success type
`E`: Error type | `[T, null] \\| [null, E]` |\n\n## ๐Ÿ›ฃ๏ธ Roadmap\n\n| Task | Status |\n| :---------------: | :----: |\n| ๐Ÿงช Add tests | ๐Ÿ”ด |\n| ๐Ÿงช Publish To JSR | ๐ŸŸข |\n| ๐Ÿงช Publish To NPM | ๐ŸŸข |\n\n## ๐Ÿ’ป Contributing\n\n> [!TIP] \n> We welcome contributions to improve **unwrap-go**! If you have suggestions, bug fixes, or new feature ideas, follow these steps:\n\n1. **Fork the Repository** you\n Click the **Fork** button at the top-right of the repo page.\n\n2. **Clone Your Fork** \n Clone the repo locally: YOU\n\n ```bash\n git clone https://github.com/ArnavK-09/unwrap-go.git\n ```\n\n3. **Create a Branch** \n Create a new branch for your changes:\n\n ```bash\n git checkout -b your-feature-branch\n ```\n\n4. **Make Changes** \n Implement your changes (bug fixes, features, etc.).\n\n5. **Commit and Push** \n Commit your changes and push the branch:\n\n ```bash\n git commit -m \"feat(scope): description\"\n git push origin your-feature-branch\n ```\n\n6. **Open a Pull Request** \n Open a PR with a detailed description of your changes.\n\n7. **Collaborate and Merge** \n The maintainers will review your PR, request changes if needed, and merge it once approved.\n\n## ๐Ÿ™‹โ€โ™‚๏ธ Issues\n\nFound a bug or need help?
