# Code Style and Contribution Guidelines
2026-01-26 07:28:33 +00:00
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.
2024-01-18 15:50:14 +00:00
## Code Style
2026-01-26 07:28:33 +00:00
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.
2024-01-18 15:50:14 +00:00
### 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`.
2025-04-08 14:23:16 +00:00
It's recommended to configure your editor to run Prettier automatically when saving files.
2024-01-18 15:50:14 +00:00
### 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.
2025-04-08 14:23:16 +00:00
### 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.
2024-01-18 15:50:14 +00:00
## Contribution Process
2026-01-26 07:28:33 +00:00
LobeHub follows the gitmoji and semantic release as our code submission and release process.
2024-01-18 15:50:14 +00:00
### 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:
2025-04-08 14:23:16 +00:00
```markdown
2024-01-18 15:50:14 +00:00
📝 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
📝 docs: improve development guides to reflect current architecture (#12174)

Add official ecosystem packages (LobeUI, LobeIcons, LobeCharts,
LobeEditor, LobeTTS, LobeLint, Lobe i18n, MCP Mark) and community
platforms (Agent Market, MCP Market, YouTube, X, Discord).
* 📝 docs: improve contributing guidelines and resources
- Clarify semantic release triggers (feat/fix vs style/chore)
- Add testing section with Vitest/E2E/CI requirements
- Update contribution steps to include CI check
- Add LobeHub ecosystem packages and community platforms to resources
* 📝 docs: rewrite architecture guide to reflect current platform design

* 📝 docs: rewrite chat-api guide to reflect current architecture
- Update sequence diagram with Agent Runtime loop as core execution engine
- Replace PluginGateway with ToolExecution layer (Builtin/MCP/Plugin)
- Update all path references (model-runtime, agent-runtime, fetch-sse packages)
- Split old AgentRuntime section into Model Runtime + Agent Runtime

* 📝 docs: restore S3_PUBLIC_DOMAIN in deployment guides
The S3_PUBLIC_DOMAIN env var was incorrectly removed from all
documentation in commit 4a87b31. This variable is still required
by the code (src/server/services/file/impls/s3.ts) to generate
public URLs for uploaded files. Without it, image URLs sent to
vision models are just S3 keys instead of full URLs.
Closes #12161
* 📦 chore: pin @lobehub/ui to 4.33.4 to fix SortableList type errors
@lobehub/ui 4.34.0 introduced breaking type changes in SortableList
where SortableListItem became strict, causing type incompatibility
in onChange and renderItem callbacks across 6 files. Pin to 4.33.4
via pnpm overrides to enforce consistent version across monorepo.
* 🐛 fix: correct ReadableStream type annotations and add dom.asynciterable
- Add dom.asynciterable to tsconfig lib for ReadableStream async iteration
- Fix createCallbacksTransformer return type: TransformStream<string, Uint8Array>
- Update stream function return types from ReadableStream<string> to
ReadableStream<Uint8Array> (llama.ts, ollama.ts, claude.ts)
- Remove @ts-ignore from for-await loops in test files
- Add explicit string[] type for chunks arrays
* Revert "📝 docs: restore S3_PUBLIC_DOMAIN in deployment guides"
This reverts commit 24073f83d3d5e9a89c29e9a96a6689d2baa0edde.
2026-02-07 14:29:14 +00:00
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`
2024-01-18 15:50:14 +00:00
### 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).
