+# Contributing to CloudCLI UI
+
+Thanks for your interest in contributing to CloudCLI UI! Before you start, please take a moment to read through this guide.
+
+## Before You Start
+
+- **Search first.** Check [existing issues](https://github.com/siteboon/claudecodeui/issues) and [pull requests](https://github.com/siteboon/claudecodeui/pulls) to avoid duplicating work.
+- **Discuss first** for new features. Open an [issue](https://github.com/siteboon/claudecodeui/issues/new) to discuss your idea before investing time in implementation. We may already have plans or opinions on how it should work.
+- **Bug fixes are always welcome.** If you spot a bug, feel free to open a PR directly.
+
+## Prerequisites
+
+- [Node.js](https://nodejs.org/) 22 or later
+- [Claude Code CLI](https://docs.anthropic.com/en/docs/claude-code) installed and configured
+
+## Getting Started
+
+1. Fork the repository
+2. Clone your fork:
+   ```bash
+   git clone https://github.com/<your-username>/claudecodeui.git
+   cd claudecodeui
+   ```
+3. Install dependencies:
+   ```bash
+   npm install
+   ```
+4. Start the development server:
+   ```bash
+   npm run dev
+   ```
+5. Create a branch for your changes:
+   ```bash
+   git checkout -b feat/your-feature-name
+   ```
+
+## Project Structure
+
+```
+claudecodeui/
+├── src/              # React frontend (Vite + Tailwind)
+│   ├── components/   # UI components
+│   ├── contexts/     # React context providers
+│   ├── hooks/        # Custom React hooks
+│   ├── i18n/         # Internationalization and translations

+├── shared/           # Code shared between client and server
+└── public/           # Static assets, icons, PWA manifest
+```
+
+## Development Workflow
+
+- `npm run dev` — Start both the frontend and backend in development mode
+- `npm run build` — Create a production build
+- `npm run server` — Start only the backend server
+- `npm run client` — Start only the Vite dev server
+
+## Making Changes
+
+### Bug Fixes
+
+- Reference the issue number in your PR if one exists
+- Describe how to reproduce the bug in your PR description
+- Add a screenshot or recording for visual bugs
+
+### New Features
+
+- Keep the scope focused — one feature per PR
+- Include screenshots or recordings for UI changes
+
+### Documentation
+
+- Documentation improvements are always welcome
+- Keep language clear and concise
+
+## Commit Convention
+
+We follow [Conventional Commits](https://conventionalcommits.org/) to generate release notes automatically. Every commit message should follow this format:
+
+```
+<type>(optional scope): <description>
+```
+
+Use imperative, present tense: "add feature" not "added feature" or "adds feature".
+
+### Types
+
+| Type | Description |
+|------|-------------|
+| `feat` | A new feature |
+| `fix` | A bug fix |
+| `perf` | A performance improvement |
+| `refactor` | Code change that neither fixes a bug nor adds a feature |
+| `docs` | Documentation only |
+| `style` | CSS, formatting, visual changes |
+| `chore` | Maintenance, dependencies, config |
+| `ci` | CI/CD pipeline changes |
+| `test` | Adding or updating tests |
+| `build` | Build system changes |
+
+### Examples
+
+```bash
+feat: add conversation search
+feat(i18n): add Japanese language support
+fix: redirect unauthenticated users to login
+fix(editor): syntax highlighting for .env files
+perf: lazy load code editor component
+refactor(chat): extract message list component
+docs: update API configuration guide
+```
+
+### Breaking Changes
+
+Add `!` after the type or include `BREAKING CHANGE:` in the commit footer:
+
+```bash
+feat!: redesign settings page layout
+```
+
+## Pull Requests
+
+- Give your PR a clear, descriptive title following the commit convention above
+- Fill in the PR description with what changed and why
+- Link any related issues
+- Include screenshots for UI changes
+- Make sure the build passes (`npm run build`)
+- Keep PRs focused — avoid unrelated changes
+
+## Releases
+
+Releases are managed by maintainers using [release-it](https://github.com/release-it/release-it) with the [conventional changelog plugin](https://github.com/release-it/conventional-changelog).
+
+```bash
+npm run release           # interactive (prompts for version bump)
+npm run release -- patch  # patch release
+npm run release -- minor  # minor release
+```
+
+This automatically:
+- Bumps the version based on commit types (`feat` = minor, `fix` = patch)
+- Generates categorized release notes
+- Updates `CHANGELOG.md`
+- Creates a git tag and GitHub Release
+- Publishes to npm

Vadim Trunov	597e9c54b7	fix: slash commands with arguments bypass command execution (#392 ) * fix: intercept slash commands in handleSubmit to pass arguments correctly When a user types a slash command with arguments (e.g. `/feature implement dark mode`) and presses Enter, the command was not being intercepted as a slash command. Instead, the raw text was sent as a regular message to the Claude API, which responded with "Unknown skill: feature". Root cause: the command autocomplete menu (useSlashCommands) detects commands via the regex `/(^\|\s)\/(\S)$/` which only matches when the cursor is right after the command name with no spaces. As soon as the user types a space to add arguments, the pattern stops matching, the menu closes, and pressing Enter falls through to handleSubmit which sends the text as a plain message — completely bypassing command execution. This fix adds a slash command interceptor at the top of handleSubmit: - Checks if the trimmed input starts with `/` - Extracts the command name (text before the first space) - Looks up the command in the loaded slashCommands list - If found, delegates to executeCommand() which properly extracts arguments via regex and sends them to the backend /api/commands/execute endpoint - The backend then replaces $ARGUMENTS, $1, $2 etc. in the command template Changes: - Added `slashCommands` to the destructured return of useSlashCommands hook - Added slash command interception logic in handleSubmit before message dispatch - Added `executeCommand` and `slashCommands` to handleSubmit dependency array Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> fix: address review — pass rawInput param and cleanup UI state - Pass trimmedInput to executeCommand to avoid stale closure reads - Add UI cleanup (images, command menu, textarea) before early return - Update executeCommand signature to accept optional rawInput parameter Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> --------- Co-authored-by: Claude Opus 4.6 <noreply@anthropic.com>	2026-02-22 16:25:02 +03:00
mjfork	cccd915c33	feat: add HOST environment variable for configurable bind address (#360 ) * feat: add HOST environment variable for configurable bind address Allow users to specify which host/IP address the servers should bind to via the HOST environment variable. Defaults to 0.0.0.0 (all interfaces) to maintain backward compatibility. This enables users to restrict the server to localhost only (127.0.0.1) for security purposes or bind to a specific network interface. Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com> * fix: use correct proxy host when HOST is set to specific interface When HOST is set to a specific interface (e.g., 192.168.1.100), the Vite proxy needs to connect to that same host, not localhost. This fix: - Adds proxyHost logic that uses localhost when HOST=0.0.0.0, otherwise uses the specific HOST value for proxy targets - Adds DISPLAY_HOST to show a user-friendly URL in console output (0.0.0.0 isn't a connectable address) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com> --------- Co-authored-by: Michael Fork <mjfork@users.noreply.github.com> Co-authored-by: Claude Opus 4.5 <noreply@anthropic.com> Co-authored-by: Haileyesus <118998054+blackmammoth@users.noreply.github.com>	2026-02-20 21:23:10 +03:00
