# Code Style and Contribution Guidelines

Welcome to the Code Style and Contribution Guidelines for LobeHub. This guide will help you understand our code standards and contribution process, ensuring code consistency and smooth project progression.

## Code Style

In LobeHub, we use the [@lobehub/lint](https://github.com/lobehub/lobe-lint) package to maintain a unified code style. This package incorporates configurations for `ESLint`, `Prettier`, `remarklint`, and `stylelint` to ensure that our JavaScript, Markdown, and CSS files adhere to the same coding standards.

### ESLint

We use ESLint to check for issues in our JavaScript code. You can find the `.eslintrc.js` file in the project's root directory, which contains our extensions and custom rules for the ESLint configuration of `@lobehub/lint`.

To ensure your code aligns with the project's standards, run ESLint before committing your code.

### Prettier

Prettier is responsible for code formatting to maintain consistency. Our Prettier configuration can be found in `.prettierrc.js`, imported from `@lobehub/lint`.

It's recommended to configure your editor to run Prettier automatically when saving files.

### remarklint

For Markdown files, we use remarklint to ensure consistent document formatting. You can find the corresponding configuration file in the project.

### stylelint

We utilize stylelint to standardize the style of our CSS code. In the configuration file for stylelint, we have made some custom rule adjustments based on `@lobehub/lint` configuration.

### Style Checking

You don't need to manually run these checks. The project is configured with husky to automatically run lint-staged when you commit code, which will check if your committed files comply with the above standards.

## Contribution Process

LobeHub follows the gitmoji and semantic release as our code submission and release process.

### Gitmoji

When committing code, please use gitmoji to label your commit messages. This helps other contributors quickly understand the content and purpose of your submission.

Gitmoji commit messages use specific emojis to represent the type or intent of the commit. Here's an example:

```markdown
📝 Update README with contribution guidelines

- Added section about code style preferences
- Included instructions for running tests
- Corrected typos and improved formatting
```

In this example, the 📝 emoji represents a documentation update. The commit message clearly describes the changes and provides specific details.

### Semantic Release

We use semantic release to automate version control and release processes. When a PR is merged into the main branch, the system automatically determines whether to publish a new version based on the gitmoji prefix in commit messages:

- Commits with `✨ feat` or `🐛 fix` prefixes will **trigger a new release**
- For minor changes that don't need a release, use prefixes like `💄 style` or `🔨 chore`

### Commitlint

To ensure consistency in commit messages, we use `commitlint` to check the format of commit messages. You can find the relevant rules in the `.commitlintrc.js` configuration file.

Before committing your code, ensure that your commit messages adhere to our standards.

### Testing

LobeHub has comprehensive unit tests (Vitest) and E2E tests (Cucumber + Playwright), which run automatically via GitHub Actions CI on every PR. Before submitting a PR or requesting a merge, make sure all tests pass.

You can run specific test files locally to verify:

```bash
# Run specific test (never run bun run test — full suite is very slow)
bunx vitest run --silent='passed-only' '[file-path]'
```

For more testing details, see the [Testing Guide](/docs/development/basic/test).

### How to Contribute

1. Fork the project to your account.
2. Create a new branch for development.
3. After completing development, ensure your code passes code style checks and tests.
4. Commit your changes and use appropriate gitmoji to label your commit message.
5. Create a Pull Request to the main branch of the original project.
6. Ensure all GitHub Actions CI checks pass.
7. Await code review and make necessary modifications based on feedback.

Thank you for following these guidelines, as they help us maintain the quality and consistency of the project. We look forward to your contributions!
