The task is not complete until ALL of the following pass with zero issues:
|
||||
|
||||
1. **Playwright E2E Tests (MANDATORY - Run First)**:
|
||||
- **Run**: `npx playwright test --project=chromium` from project root
|
||||
- **PREREQUISITE**: Rebuild E2E container before each test run:
|
||||
```bash
|
||||
.github/skills/scripts/skill-runner.sh docker-rebuild-e2e
|
||||
```
|
||||
This ensures the container has latest code and proper environment variables (emergency token, encryption key from `.env`).
|
||||
- **Run**: `npx playwright test --project=chromium --project=firefox --project=webkit` from project root
|
||||
- **No Truncation**: Never pipe output through `head`, `tail`, or other truncating commands. Playwright requires user input to quit when piped, causing hangs.
|
||||
- **Why First**: If the app is broken at E2E level, unit tests may need updates. Catch integration issues early.
|
||||
- **Scope**: Run tests relevant to modified features (e.g., `tests/manual-dns-provider.spec.ts`)

|
||||
|
||||
## Guidelines
|
||||
|
||||
- Always use functional components with hooks - class components are legacy
|
||||
- Leverage React 19.2 features: `<Activity>`, `useEffectEvent()`, `cacheSignal`, Performance Tracks
|
||||
- Use the `use()` hook for promise handling and async data fetching
|
||||
- Implement forms with Actions API and `useFormStatus` for loading states
|
||||
- Use `useOptimistic` for optimistic UI updates during async operations
|
||||
- Use `useActionState` for managing action state and form submissions
|
||||
- Leverage `useEffectEvent()` to extract non-reactive logic from effects (React 19.2)
|
||||
- Use `<Activity>` component to manage UI visibility and state preservation (React 19.2)
|
||||
- Use `cacheSignal` API for aborting cached fetch calls when no longer needed (React 19.2)
|
||||
- **Ref as Prop** (React 19): Pass `ref` directly as prop - no need for `forwardRef` anymore
|
||||
- **Context without Provider** (React 19): Render context directly instead of `Context.Provider`
|
||||
- Implement Server Components for data-heavy components when using frameworks like Next.js
|
||||
- Mark Client Components explicitly with `'use client'` directive when needed
|
||||
- Use `startTransition` for non-urgent updates to keep the UI responsive
|
||||
- Leverage Suspense boundaries for async data fetching and code splitting
|
||||
- No need to import React in every file - new JSX transform handles it
|
||||
- Use strict TypeScript with proper interface design and discriminated unions
|
||||
- Implement proper error boundaries for graceful error handling
|
||||
- Use semantic HTML elements (`<button>`, `<nav>`, `<main>`, etc.) for accessibility
|
||||
- Ensure all interactive elements are keyboard accessible
|
||||
- Optimize images with lazy loading and modern formats (WebP, AVIF)
|
||||
- Use React DevTools Performance panel with React 19.2 Performance Tracks
|
||||
- Implement code splitting with `React.lazy()` and dynamic imports
|
||||
- Use proper dependency arrays in `useEffect`, `useMemo`, and `useCallback`
|
||||
- Ref callbacks can now return cleanup functions for easier cleanup management
|
||||

import { use, Suspense } from "react";
|
||||
|
||||
interface User {
|
||||
id: number;
|
||||
name: string;
|
||||
email: string;
|

if (!res.ok) throw new Error("Failed to fetch user");
|
||||
return res.json();
|
||||
}
|
||||
|
||||
function UserProfile({ userPromise }: { userPromise: Promise<User> }) {
|
||||
// use() hook suspends rendering until promise resolves
|
||||
const user = use(userPromise);
|
||||
|
||||
return (
|
||||
<div>
|
||||
<h2>{user.name}</h2>
|
||||
<p>{user.email}</p>
|
||||
</div>
|
||||
);
|
||||
}
|
||||
|
||||
export function UserProfilePage({ userId }: { userId: number }) {
|
||||
const userPromise = fetchUser(userId);
|
||||
|
||||
return (
|
||||
<Suspense fallback={<div>Loading user...</div>}>
|
||||
<UserProfile userPromise={userPromise} />
|
||||
</Suspense>
|
||||
);
|
||||
}
|
||||
```
|
||||
|
||||
### Form with Actions and useFormStatus (React 19)
|
||||
|
||||
```typescript
|
||||
import { useFormStatus } from "react-dom";
|
||||
import { useActionState } from "react";
|
||||
|
||||
// Submit button that shows pending state
|
||||
function SubmitButton() {
|
||||
const { pending } = useFormStatus();
|
||||
|
||||
return (
|
||||
<button type="submit" disabled={pending}>
|
||||
{pending ? "Submitting..." : "Submit"}
|
||||
</button>
|
||||
);
|
||||
}
|
||||
|
||||
interface FormState {
|
||||
error?: string;
|
||||
success?: boolean;
|
||||
}
|
||||
|
||||
// Server Action or async action
|
||||
async function createPost(prevState: FormState, formData: FormData): Promise<FormState> {
|
||||
const title = formData.get("title") as string;
|
||||
const content = formData.get("content") as string;
|
||||
|
||||
if (!title || !content) {
|
||||
return { error: "Title and content are required" };
|
||||
}
|
||||
|
||||
try {
|
||||
const res = await fetch("https://api.example.com/posts", {
|
||||
method: "POST",
|
||||
headers: { "Content-Type": "application/json" },
|
||||
body: JSON.stringify({ title, content }),
|
||||
});
|
||||
|
||||
if (!res.ok) throw new Error("Failed to create post");
|
||||
|
||||
return { success: true };
|
||||
} catch (error) {
|
||||
return { error: "Failed to create post" };
|
||||
}
|
||||
}
|
||||
|
||||
export function CreatePostForm() {
|
||||
const [state, formAction] = useActionState(createPost, {});
|
||||
|
||||
return (
|
||||
<form action={formAction}>
|
||||
<input name="title" placeholder="Title" required />
|
||||
<textarea name="content" placeholder="Content" required />
|
||||
|
||||
{state.error && <p className="error">{state.error}</p>}
|
||||
{state.success && <p className="success">Post created!</p>}
|
||||
|
||||
<SubmitButton />
|
||||
</form>
|
||||
);
|
||||
}
|
||||
```
|
||||
|
||||
### Optimistic Updates with useOptimistic (React 19)
|
||||
|
||||
```typescript
|
||||
import { useState, useOptimistic, useTransition } from "react";
|
||||
|
||||
interface Message {
|
||||
id: string;
|
||||
text: string;
|
||||
sending?: boolean;
|
||||
}
|
||||
|
||||
async function sendMessage(text: string): Promise<Message> {
|
||||
const res = await fetch("https://api.example.com/messages", {
|
||||
method: "POST",
|
||||
headers: { "Content-Type": "application/json" },
|
||||
body: JSON.stringify({ text }),
|
||||
});
|
||||
return res.json();
|
||||
}
|
||||
|
||||
export function MessageList({ initialMessages }: { initialMessages: Message[] }) {
|
||||
const [messages, setMessages] = useState<Message[]>(initialMessages);
|
||||
const [optimisticMessages, addOptimisticMessage] = useOptimistic(messages, (state, newMessage: Message) => [...state, newMessage]);
|
||||
const [isPending, startTransition] = useTransition();
|
||||
|
||||
const handleSend = async (text: string) => {
|
||||
const tempMessage: Message = {
|
||||
id: `temp-${Date.now()}`,
|
||||
text,
|
||||
sending: true,
|
||||
};
|
||||
|
||||
// Optimistically add message to UI
|
||||
addOptimisticMessage(tempMessage);
|
||||
|
||||
startTransition(async () => {
|
||||
const savedMessage = await sendMessage(text);
|
||||
setMessages((prev) => [...prev, savedMessage]);
|
||||
});
|
||||
};
|
||||
|
||||
return (
|
||||
<div>
|
||||
{optimisticMessages.map((msg) => (
|
||||
<div key={msg.id} className={msg.sending ? "opacity-50" : ""}>
|
||||
{msg.text}
|
||||
</div>
|
||||
))}
|
||||
<MessageInput onSend={handleSend} disabled={isPending} />
|
||||
</div>
|
||||
);
|
||||
}
|
||||
```
|
||||
|
||||
### Using useEffectEvent (React 19.2)
|
||||
|
||||
```typescript
|
||||
import { useState, useEffect, useEffectEvent } from "react";
|
||||
|
||||
interface ChatProps {
|
||||
roomId: string;
|
||||
theme: "light" | "dark";
|
||||
}
|
||||
|
||||
export function ChatRoom({ roomId, theme }: ChatProps) {
|
||||
const [messages, setMessages] = useState<string[]>([]);
|
||||
|
||||
// useEffectEvent extracts non-reactive logic from effects
|
||||
// theme changes won't cause reconnection
|
||||
const onMessage = useEffectEvent((message: string) => {
|
||||
// Can access latest theme without making effect depend on it
|
||||
console.log(`Received message in ${theme} theme:`, message);
|
||||
setMessages((prev) => [...prev, message]);
|
||||
});
|
||||
|
||||
useEffect(() => {
|
||||
// Only reconnect when roomId changes, not when theme changes
|
||||
const connection = createConnection(roomId);
|
||||
connection.on("message", onMessage);
|
||||
connection.connect();
|
||||
|
||||
return () => {
|
||||
connection.disconnect();
|
||||
};
|
||||
}, [roomId]); // theme not in dependencies!
|
||||
|
||||
return (
|
||||
<div className={theme}>
|
||||
{messages.map((msg, i) => (
|
||||
<div key={i}>{msg}</div>
|
||||
))}
|
||||
</div>
|
||||
);
|
||||
}
|
||||
```
|
||||
|
||||
### Using <Activity> Component (React 19.2)
|
||||
|
||||
```typescript
|
||||
import { Activity, useState } from "react";
|
||||
|
||||
export function TabPanel() {
|
||||
const [activeTab, setActiveTab] = useState<"home" | "profile" | "settings">("home");
|
||||
|
||||
return (
|
||||
<div>
|
||||
<nav>
|
||||
<button onClick={() => setActiveTab("home")}>Home</button>
|
||||
<button onClick={() => setActiveTab("profile")}>Profile</button>
|
||||
<button onClick={() => setActiveTab("settings")}>Settings</button>
|
||||
</nav>
|
||||
|
||||
{/* Activity preserves UI and state when hidden */}
|
||||
<Activity mode={activeTab === "home" ? "visible" : "hidden"}>
|
||||
<HomeTab />
|
||||
</Activity>
|
||||
|
||||
<Activity mode={activeTab === "profile" ? "visible" : "hidden"}>
|
||||
<ProfileTab />
|
||||
</Activity>
|
||||
|
||||
<Activity mode={activeTab === "settings" ? "visible" : "hidden"}>
|
||||
<SettingsTab />
|
||||
</Activity>
|
||||
</div>
|
||||
);
|
||||
}
|
||||
|
||||
function HomeTab() {
|
||||
// State is preserved when tab is hidden and restored when visible
|
||||
const [count, setCount] = useState(0);
|
||||
|
||||
return (
|
||||
<div>
|
||||
<p>Count: {count}</p>
|
||||
<button onClick={() => setCount(count + 1)}>Increment</button>
|
||||
</div>
|
||||
);
|
||||
}
|
||||
```
|
||||
|
||||
### Custom Hook with TypeScript Generics
|
||||
|
||||
```typescript
|
||||
import { useState, useEffect } from "react";
|
||||
|
||||
interface UseFetchResult<T> {
|
||||
data: T | null;
|
||||
loading: boolean;
|
||||
error: Error | null;
|
||||
refetch: () => void;
|
||||
}
|
||||
|
||||
export function useFetch<T>(url: string): UseFetchResult<T> {
|
||||
const [data, setData] = useState<T | null>(null);
|
||||
const [loading, setLoading] = useState(true);
|
||||
const [error, setError] = useState<Error | null>(null);
|
||||
const [refetchCounter, setRefetchCounter] = useState(0);
|
||||
|
||||
useEffect(() => {
|
||||
let cancelled = false;
|
||||
|
||||
const fetchData = async () => {
|
||||
try {
|

setError(null);
|
||||
|
||||
const response = await fetch(url);
|
||||
if (!response.ok) throw new Error(`HTTP error ${response.status}`);
|
||||
|
||||
const json = await response.json();
|
||||
|
||||
if (!cancelled) {
|
||||
setData(json);
|
||||
}
|
||||
} catch (err) {
|
||||
if (!cancelled) {
|
||||
setError(err instanceof Error ? err : new Error("Unknown error"));
|
||||
}
|
||||
} finally {
|
||||
if (!cancelled) {
|
||||
setLoading(false);
|
||||
}
|
||||
}
|
||||
};
|
||||
|
||||
fetchData();
|
||||
|
||||
return () => {
|
||||
cancelled = true;
|
||||
};
|
||||
}, [url, refetchCounter]);
|
||||
|
||||
const refetch = () => setRefetchCounter((prev) => prev + 1);
|
||||
|
||||
return { data, loading, error, refetch };
|
||||
}
|
||||
|
||||
// Usage with type inference
|
||||
function UserList() {

return (
|
||||
<ul>
|
||||
{data.map((user) => (
|
||||
<li key={user.id}>{user.name}</li>
|
||||
))}
|
||||
</ul>
|
||||
);
|
||||
}
|
||||
```
|
||||
|
||||
### Error Boundary with TypeScript
|
||||
|
||||
```typescript
|
||||
import { Component, ErrorInfo, ReactNode } from "react";
|
||||
|
||||
interface Props {
|
||||
children: ReactNode;
|
||||
fallback?: ReactNode;
|
||||
}
|
||||
|
||||
interface State {
|
||||
hasError: boolean;
|
||||
error: Error | null;
|
||||
}
|
||||
|
||||
export class ErrorBoundary extends Component<Props, State> {
|
||||
constructor(props: Props) {
|
||||
super(props);
|
||||
this.state = { hasError: false, error: null };
|
||||
}
|
||||
|
||||
static getDerivedStateFromError(error: Error): State {
|
||||
return { hasError: true, error };
|
||||
}
|
||||
|
||||
componentDidCatch(error: Error, errorInfo: ErrorInfo) {
|
||||
console.error("Error caught by boundary:", error, errorInfo);
|
||||
// Log to error reporting service
|
||||
}
|
||||
|
||||
render() {
|
||||
if (this.state.hasError) {
|
||||
return (
|
||||
this.props.fallback || (
|
||||
<div role="alert">
|
||||
<h2>Something went wrong</h2>
|
||||
<details>
|
||||
<summary>Error details</summary>
|
||||
<pre>{this.state.error?.message}</pre>
|
||||
</details>
|
||||
<button onClick={() => this.setState({ hasError: false, error: null })}>Try again</button>
|
||||
</div>
|
||||
)
|
||||
);
|
||||
}
|
||||
|
||||
return this.props.children;
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### Using cacheSignal for Resource Cleanup (React 19.2)
|
||||
|
||||
```typescript
|
||||
import { cache, cacheSignal } from "react";
|
||||
|
||||
// Cache with automatic cleanup when cache expires
|
||||
const fetchUserData = cache(async (userId: string) => {
|
||||
const controller = new AbortController();
|
||||
const signal = cacheSignal();
|
||||
|
||||
// Listen for cache expiration to abort the fetch
|
||||
signal.addEventListener("abort", () => {
|
||||
console.log(`Cache expired for user ${userId}`);
|
||||
controller.abort();
|
||||
});
|
||||
|
||||
try {
|
||||
const response = await fetch(`https://api.example.com/users/${userId}`, {
|
||||
signal: controller.signal,
|
||||
});
|
||||
|
||||
if (!response.ok) throw new Error("Failed to fetch user");
|
||||
return await response.json();
|
||||
} catch (error) {
|
||||
if (error.name === "AbortError") {
|
||||
console.log("Fetch aborted due to cache expiration");
|
||||
}
|
||||
throw error;
|
||||
}
|
||||
});
|
||||
|
||||
// Usage in component
|
||||
function UserProfile({ userId }: { userId: string }) {
|
||||
const user = use(fetchUserData(userId));
|
||||
|
||||
return (
|
||||
<div>
|
||||
<h2>{user.name}</h2>
|
||||
<p>{user.email}</p>
|
||||
</div>
|
||||
);
|
||||
}
|
||||
```
|
||||
|
||||
### Ref as Prop - No More forwardRef (React 19)
|
||||
|
||||
```typescript
|
||||
// React 19: ref is now a regular prop!
|
||||
interface InputProps {
|
||||
placeholder?: string;
|
||||
ref?: React.Ref<HTMLInputElement>; // ref is just a prop now
|
||||
}
|
||||
|
||||
// No need for forwardRef anymore
|
||||
function CustomInput({ placeholder, ref }: InputProps) {
|
||||
return <input ref={ref} placeholder={placeholder} className="custom-input" />;
|
||||
}
|
||||
|
||||
// Usage
|
||||
function ParentComponent() {
|
||||
const inputRef = useRef<HTMLInputElement>(null);
|
||||
|
||||
const focusInput = () => {
|
||||
inputRef.current?.focus();
|
||||
};
|
||||
|
||||
return (
|
||||
<div>
|
||||
<CustomInput ref={inputRef} placeholder="Enter text" />
|
||||
<button onClick={focusInput}>Focus Input</button>
|
||||
</div>
|
||||
);
|
||||
}
|
||||
```
|
||||
|
||||
### Context Without Provider (React 19)
|
||||
|
||||
```typescript
|
||||
import { createContext, useContext, useState } from "react";
|
||||
|
||||
interface ThemeContextType {
|
||||
theme: "light" | "dark";
|
||||
toggleTheme: () => void;
|
||||
}
|
||||
|
||||
// Create context
|
||||
const ThemeContext = createContext<ThemeContextType | undefined>(undefined);
|
||||
|
||||
// React 19: Render context directly instead of Context.Provider
|
||||
function App() {
|
||||
const [theme, setTheme] = useState<"light" | "dark">("light");
|
||||
|
||||
const toggleTheme = () => {
|
||||
setTheme((prev) => (prev === "light" ? "dark" : "light"));
|
||||
};
|
||||
|
||||
const value = { theme, toggleTheme };
|
||||
|
||||
// Old way: <ThemeContext.Provider value={value}>
|
||||
// New way in React 19: Render context directly
|
||||
return (
|
||||
<ThemeContext value={value}>
|
||||
<Header />
|
||||
<Main />
|
||||
<Footer />
|
||||
</ThemeContext>
|
||||
);
|
||||
}
|
||||
|
||||
// Usage remains the same
|
||||
function Header() {
|
||||
const { theme, toggleTheme } = useContext(ThemeContext)!;
|
||||
|
||||
return (
|
||||
<header className={theme}>
|
||||
<button onClick={toggleTheme}>Toggle Theme</button>
|
||||
</header>
|
||||
);
|
||||
}
|
||||
```
|
||||
|
||||
### Ref Callback with Cleanup Function (React 19)
|
||||
|
||||
```typescript
|
||||
import { useState } from "react";
|
||||
|
||||
function VideoPlayer() {
|
||||
const [isPlaying, setIsPlaying] = useState(false);
|
||||
|
||||
// React 19: Ref callbacks can now return cleanup functions!
|
||||
const videoRef = (element: HTMLVideoElement | null) => {
|
||||
if (element) {
|
||||
console.log("Video element mounted");
|
||||
|
||||
// Set up observers, listeners, etc.
|
||||
const observer = new IntersectionObserver((entries) => {
|
||||
entries.forEach((entry) => {
|
||||
if (entry.isIntersecting) {
|
||||
element.play();
|
||||
} else {
|
||||
element.pause();
|
||||
}
|
||||
});
|
||||
});
|
||||
|
||||
observer.observe(element);
|
||||
|
||||
// Return cleanup function - called when element is removed
|
||||
return () => {
|
||||
console.log("Video element unmounting - cleaning up");
|
||||
observer.disconnect();
|
||||
element.pause();
|
||||
};
|
||||
}
|
||||
};
|
||||
|
||||
return (
|
||||
<div>
|
||||
<video ref={videoRef} src="/video.mp4" controls />
|
||||
<button onClick={() => setIsPlaying(!isPlaying)}>{isPlaying ? "Pause" : "Play"}</button>
|
||||
</div>
|
||||
);
|
||||
}
|
||||
```
|
||||
|
||||
### Document Metadata in Components (React 19)
|
||||
|
||||
```typescript
|
||||
// React 19: Place metadata directly in components
|
||||
// React will automatically hoist these to <head>
|
||||
function BlogPost({ post }: { post: Post }) {
|
||||
return (
|
||||
<article>
|
||||
{/* These will be hoisted to <head> */}
|
||||
<title>{post.title} - My Blog</title>
|
||||
<meta name="description" content={post.excerpt} />
|
||||
<meta property="og:title" content={post.title} />
|
||||
<meta property="og:description" content={post.excerpt} />
|
||||
<link rel="canonical" href={`https://myblog.com/posts/${post.slug}`} />
|
||||
|
||||
{/* Regular content */}
|
||||
<h1>{post.title}</h1>
|
||||
<div dangerouslySetInnerHTML={{ __html: post.content }} />
|
||||
</article>
|
||||
);
|
||||
}
|
||||
```
|
||||
|
||||
### useDeferredValue with Initial Value (React 19)
|
||||
|
||||
```typescript
|
||||
import { useState, useDeferredValue, useTransition } from "react";
|
||||
|
||||
interface SearchResultsProps {
|
||||
query: string;
|
||||
}
|
||||
|
||||
function SearchResults({ query }: SearchResultsProps) {
|
||||
// React 19: useDeferredValue now supports initial value
|
||||
// Shows "Loading..." initially while first deferred value loads
|
||||
const deferredQuery = useDeferredValue(query, "Loading...");
|
||||
|
||||
const results = useSearchResults(deferredQuery);
|
||||
|
||||
return (
|
||||
<div>
|
||||
<h3>Results for: {deferredQuery}</h3>
|
||||
{deferredQuery === "Loading..." ? (
|
||||
<p>Preparing search...</p>
|
||||
) : (
|
||||
<ul>
|
||||
{results.map((result) => (
|
||||
<li key={result.id}>{result.title}</li>
|
||||
))}
|
||||
</ul>
|
||||
)}
|
||||
</div>
|
||||
);
|
||||
}
|
||||
|
||||
function SearchApp() {
|
||||
const [query, setQuery] = useState("");
|
||||
const [isPending, startTransition] = useTransition();
|
||||
|
||||
const handleSearch = (value: string) => {
|
||||
startTransition(() => {
|
||||
setQuery(value);
|
||||
});
|
||||
};
|
||||
|
||||
return (
|
||||
<div>
|
||||
<input type="search" onChange={(e) => handleSearch(e.target.value)} placeholder="Search..." />
|
||||
{isPending && <span>Searching...</span>}
|
||||
<SearchResults query={query} />
|
||||
</div>
|
||||
);
|
||||
}
|
||||
```
|
||||

# Git Commit Message Best Practices
|
||||
|
||||
Comprehensive guidelines for crafting high-quality commit messages that improve code review efficiency, project documentation, and team collaboration. Based on industry standards and the conventional commits specification.
|
||||
|
||||
## Why Good Commit Messages Matter
|
||||
|
||||
- **Future Reference**: Commit messages serve as project documentation
|
||||
- **Code Review**: Clear messages speed up review processes
|
||||
- **Debugging**: Easy to trace when and why changes were introduced
|
||||
- **Collaboration**: Helps team members understand project evolution
|
||||
- **Search and Filter**: Well-structured messages are easier to search
|
||||
- **Automation**: Enables automated changelog generation and semantic versioning
|
||||
|
||||
## Commit Message Structure
|
||||
|
||||
A Git commit message consists of two parts:
|
||||
|
||||
```
|
||||
<type>(<scope>): <subject>
|
||||
|
||||
<body>
|
||||
|
||||
<footer>
|
||||
```
|
||||
|
||||
### Summary/Title (Required)
|
||||
|
||||
- **Character Limit**: 50 characters (hard limit: 72)
|
||||
- **Format**: `<type>(<scope>): <subject>`
|
||||
- **Imperative Mood**: Use "Add feature" not "Added feature" or "Adds feature"
|
||||
- **No Period**: Don't end with punctuation
|
||||
- **Lowercase Type**: Use lowercase for the type prefix
|
||||
|
||||
**Test Formula**: "If applied, this commit will [your commit message]"
|
||||
|
||||
✅ **Good**: `If applied, this commit will fix login redirect bug`
|
||||
❌ **Bad**: `If applied, this commit will fixed login redirect bug`
|
||||
|
||||
### Description/Body (Optional but Recommended)
|
||||
|
||||
- **When to Use**: Complex changes, breaking changes, or context needed
|
||||
- **Character Limit**: Wrap at 72 characters per line
|
||||
- **Content**: Explain WHAT changed and WHY (not HOW - code shows that)
|
||||
- **Blank Line**: Separate body from title with one blank line
|
||||
- **Multiple Paragraphs**: Allowed, separated by blank lines
|
||||
- **Lists**: Use bullets (`-` or `*`) or numbered lists
|
||||
|
||||
### Footer (Optional)
|
||||
|
||||
- **Breaking Changes**: `BREAKING CHANGE: description`
|
||||
- **Issue References**: `Closes #123`, `Fixes #456`, `Refs #789`
|
||||
- **Pull Request References**: `Related to PR #100`
|
||||
- **Co-authors**: `Co-authored-by: Name <email>`
|
||||
|
||||
## Conventional Commit Types
|
||||
|
||||
Use these standardized types for consistency and automated tooling:
|
||||
|
||||
| Type | Description | Example | When to Use |
|
||||
|------|-------------|---------|-------------|
|
||||
| `feat` | New user-facing feature | `feat: add password reset email` | New functionality visible to users |
|
||||
| `fix` | Bug fix in application code | `fix: correct validation logic for email` | Fixing a bug that affects users |
|
||||
| `chore` | Infrastructure, tooling, dependencies | `chore: upgrade Go to 1.21` | CI/CD, build scripts, dependencies |
|
||||
| `docs` | Documentation only | `docs: update installation guide` | README, API docs, comments |
|
||||
| `style` | Code style/formatting (no logic change) | `style: format with prettier` | Linting, formatting, whitespace |
|
||||
| `refactor` | Code restructuring (no functional change) | `refactor: extract user validation logic` | Improving code without changing behavior |
|
||||
| `perf` | Performance improvement | `perf: cache database query results` | Optimizations that improve speed/memory |
|
||||
| `test` | Adding or updating tests | `test: add unit tests for auth module` | Test files or test infrastructure |
|
||||
| `build` | Build system or external dependencies | `build: update webpack config` | Build tools, package managers |
|
||||
| `ci` | CI/CD configuration changes | `ci: add code coverage reporting` | GitHub Actions, deployment scripts |
|
||||
| `revert` | Reverts a previous commit | `revert: revert commit abc123` | Undoing a previous commit |
|
||||
|
||||
### Scope (Optional but Recommended)
|
||||
|
||||
Add scope in parentheses to specify what part of the codebase changed:
|
||||
|
||||
```
|
||||
feat(auth): add OAuth2 provider support
|
||||
fix(api): handle null response from external service
|
||||
docs(readme): add Docker installation instructions
|
||||
chore(deps): upgrade React to 18.3.0
|
||||
```
|
||||
|
||||
**Common Scopes**:
|
||||
- Component names: `(button)`, `(modal)`, `(navbar)`
|
||||
- Module names: `(auth)`, `(api)`, `(database)`
|
||||
- Feature areas: `(settings)`, `(profile)`, `(checkout)`
|
||||
- Layer names: `(frontend)`, `(backend)`, `(infrastructure)`
|
||||
|
||||
## Quick Guidelines
|
||||
|
||||
✅ **DO**:
|
||||
- Use imperative mood: "Add", "Fix", "Update", "Remove"
|
||||
- Start with lowercase type: `feat:`, `fix:`, `docs:`
|
||||
- Be specific: "Fix login redirect" not "Fix bug"
|
||||
- Reference issues/tickets: `Fixes #123`
|
||||
- Commit frequently with focused changes
|
||||
- Write for your future self and team
|
||||
- Double-check spelling and grammar
|
||||
- Use conventional commit types
|
||||
|
||||
❌ **DON'T**:
|
||||
- End summary with punctuation (`.`, `!`, `?`)
|
||||
- Use past tense: "Added", "Fixed", "Updated"
|
||||
- Use vague messages: "Fix stuff", "Update code", "WIP"
|
||||
- Capitalize randomly: "Fix Bug in Login"
|
||||
- Commit everything at once: "Update multiple files"
|
||||
- Use humor/emojis in professional contexts (unless team standard)
|
||||
- Write commit messages when tired or rushed
|
||||
|
||||
## Examples
|
||||
|
||||
### ✅ Excellent Examples
|
||||
|
||||
#### Simple Feature
|
||||
```
|
||||
feat(auth): add two-factor authentication
|
||||
|
||||
Implement TOTP-based 2FA using the speakeasy library.
|
||||
Users can enable 2FA in account settings.
|
||||
|
||||
Closes #234
|
||||
```
|
||||
|
||||
#### Bug Fix with Context
|
||||
```
|
||||
fix(api): prevent race condition in user updates
|
||||
|
||||
Previously, concurrent updates to user profiles could
|
||||
result in lost data. Added optimistic locking with
|
||||
version field to detect conflicts.
|
||||
|
||||
The retry logic attempts up to 3 times before failing.
|
||||
|
||||
Fixes #567
|
||||
```
|
||||
|
||||
#### Documentation Update
|
||||
```
|
||||
docs: add troubleshooting section to README
|
||||
|
||||
Include solutions for common installation issues:
|
||||
- Node version compatibility
|
||||
- Database connection errors
|
||||
- Environment variable configuration
|
||||
```
|
||||
|
||||
#### Dependency Update
|
||||
```
|
||||
chore(deps): upgrade express from 4.17 to 4.19
|
||||
|
||||
Security patch for CVE-2024-12345. No breaking changes
|
||||
or API modifications required.
|
||||
```
|
||||
|
||||
#### Breaking Change
|
||||
```
|
||||
feat(api): redesign user authentication endpoint
|
||||
|
||||
BREAKING CHANGE: The /api/login endpoint now returns
|
||||
a JWT token in the response body instead of a cookie.
|
||||
Clients must update to include the Authorization header
|
||||
in subsequent requests.
|
||||
|
||||
Migration guide: docs/migration/auth-token.md
|
||||
Closes #789
|
||||
```
|
||||
|
||||
#### Refactoring
|
||||
```
|
||||
refactor(services): extract user service interface
|
||||
|
||||
Move user-related business logic from handlers to a
|
||||
dedicated service layer. No functional changes.
|
||||
|
||||
Improves testability and separation of concerns.
|
||||
```
|
||||
|
||||
### ❌ Bad Examples
|
||||
|
||||
```
|
||||
❌ update files
|
||||
→ Too vague - what was updated and why?
|
||||
|
||||
❌ Fixed the login bug.
|
||||
→ Past tense, period at end, no context
|
||||
|
||||
❌ feat: Add new feature for users to be able to...
|
||||
→ Too long for title, should be in body
|
||||
|
||||
❌ WIP
|
||||
→ Not descriptive, doesn't explain intent
|
||||
|
||||
❌ Merge branch 'feature/xyz'
|
||||
→ Meaningless merge commit (use squash or rebase)
|
||||
|
||||
❌ asdfasdf
|
||||
→ Completely unhelpful
|
||||
|
||||
❌ Fixes issue
|
||||
→ Which issue? No issue number
|
||||
|
||||
❌ Updated stuff in the backend
|
||||
→ Vague, no technical detail
|
||||
```
|
||||
|
||||
## Advanced Guidelines
|
||||
|
||||
### Atomic Commits
|
||||
|
||||
Each commit should represent one logical change:
|
||||
|
||||
✅ **Good**: Three separate commits
|
||||
```
|
||||
feat(auth): add login endpoint
|
||||
feat(auth): add logout endpoint
|
||||
test(auth): add integration tests for auth endpoints
|
||||
```
|
||||
|
||||
❌ **Bad**: One commit with everything
|
||||
```
|
||||
feat: implement authentication system
|
||||
(Contains login, logout, tests, and unrelated CSS changes)
|
||||
```
|
||||
|
||||
### Commit Frequency
|
||||
|
||||
**Commit often to**:
|
||||
- Keep messages focused and simple
|
||||
- Make code review easier
|
||||
- Simplify debugging with `git bisect`
|
||||
- Reduce risk of lost work
|
||||
|
||||
**Good rhythm**:
|
||||
- After completing a logical unit of work
|
||||
- Before switching tasks or taking a break
|
||||
- When tests pass for a feature component
|
||||
|
||||
### Issue/Ticket References
|
||||
|
||||
Include issue references in the footer:
|
||||
|
||||
```
|
||||
feat(api): add rate limiting middleware
|
||||
|
||||
Implement rate limiting using express-rate-limit to
|
||||
prevent API abuse. Default: 100 requests per 15 minutes.
|

## Team-Specific Customization
|
||||
|
||||
### Define Team Standards
|
||||
|
||||
Document your team's commit message conventions:
|
||||
|
||||
1. **Type Usage**: Which types your team uses (subset of conventional)
|
||||
2. **Scope Format**: How to name scopes (kebab-case? camelCase?)
|
||||
3. **Issue Format**: Jira ticket format vs GitHub issues
|
||||
4. **Special Markers**: Any team-specific prefixes or tags
|
||||
5. **Breaking Changes**: How to communicate breaking changes
|
||||
|
||||
### Example Team Rules
|
||||
|
||||
```markdown
|
||||
## Team Commit Standards
|
||||
|
||||
- Always include scope for domain code
|
||||
- Use JIRA ticket format: `PROJECT-123`
|
||||
- Mark breaking changes with [BREAKING] prefix in title
|
||||
- Include emoji prefix: ✨ feat, 🐛 fix, 📚 docs
|
||||
- All feat/fix must reference a ticket
|
||||
```
|
||||
|
||||
## Validation and Enforcement
|
||||
|
||||
### Pre-commit Hooks
|
||||
|
||||
Use tools to enforce commit message standards:
|
||||
|
||||
**commitlint** (Recommended)
|
||||
```bash
|
||||
npm install --save-dev @commitlint/{cli,config-conventional}
|
||||
```
|
||||
|
||||
**.commitlintrc.json**
|
||||
```json
|
||||
{
|
||||
"extends": ["@commitlint/config-conventional"],
|
||||
"rules": {
|
||||
"type-enum": [2, "always", [
|
||||
"feat", "fix", "docs", "style", "refactor",
|
||||
"perf", "test", "build", "ci", "chore", "revert"
|
||||
]],
|
||||
"subject-case": [2, "always", "sentence-case"],
|
||||
"subject-max-length": [2, "always", 50],
|
||||
"body-max-line-length": [2, "always", 72]
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### Manual Validation Checklist
|
||||
|
||||
Before committing, verify:
|
||||
|
||||
- [ ] Type is correct and lowercase
|
||||
- [ ] Subject is imperative mood
|
||||
- [ ] Subject is 50 characters or less
|
||||
- [ ] No period at end of subject
|
||||
- [ ] Body lines wrap at 72 characters
|
||||
- [ ] Body explains WHAT and WHY, not HOW
|
||||
- [ ] Issue/ticket referenced if applicable
|
||||
- [ ] Spelling and grammar checked
|
||||
- [ ] Breaking changes documented
|
||||
- [ ] Tests pass
|
||||
|
||||
## Tools for Better Commit Messages
|
||||
|
||||
### Git Commit Template
|
||||
|
||||
Create a commit template to remind you of the format:
|
||||
|
||||
**~/.gitmessage**
|
||||
```
|
||||
# <type>(<scope>): <subject> (max 50 chars)
|
||||
# |<---- Using a Maximum Of 50 Characters ---->|
|
||||
|
||||
# Explain why this change is being made
|
||||
# |<---- Try To Limit Each Line to a Maximum Of 72 Characters ---->|
|
||||
|
||||
# Provide links or keys to any relevant tickets, articles or other resources
|
||||
# Example: Fixes #23
|
||||
|
||||
# --- COMMIT END ---
|
||||
# Type can be:
|
||||
# feat (new feature)
|
||||
# fix (bug fix)
|
||||
# refactor (refactoring production code)
|
||||
# style (formatting, missing semi colons, etc; no code change)
|
||||
# docs (changes to documentation)
|
||||
# test (adding or refactoring tests; no production code change)
|
||||
# chore (updating grunt tasks etc; no production code change)
|
||||
# --------------------
|
||||
# Remember to:
|
||||
# - Use imperative mood in subject line
|
||||
# - Do not end the subject line with a period
|
||||
# - Capitalize the subject line
|
||||
# - Separate subject from body with a blank line
|
||||
# - Use the body to explain what and why vs. how
|
||||
# - Can use multiple lines with "-" for bullet points in body
|
||||
```
|
||||
|
||||
**Enable it**:
|
||||
```bash
|
||||
git config --global commit.template ~/.gitmessage
|
||||
```
|
||||
|
||||
### IDE Extensions
|
||||
|
||||
- **VS Code**: GitLens, Conventional Commits
|
||||
- **JetBrains**: Git Commit Template
|
||||
- **Sublime**: Git Commitizen
|
||||
|
||||
### Git Aliases for Quick Commits
|
||||
|
||||
```bash
|
||||
# Add to ~/.gitconfig or ~/.git/config
|
||||
[alias]
|
||||
cf = "!f() { git commit -m \"feat: $1\"; }; f"
|
||||
cx = "!f() { git commit -m \"fix: $1\"; }; f"
|
||||
cd = "!f() { git commit -m \"docs: $1\"; }; f"
|
||||
cc = "!f() { git commit -m \"chore: $1\"; }; f"
|
||||
```
|
||||
|
||||
**Usage**:
|
||||
```bash
|
||||
git cf "add user authentication" # Creates: feat: add user authentication
|
||||
git cx "resolve null pointer in handler" # Creates: fix: resolve null pointer in handler
|
||||
```
|
||||
|
||||
## Amending and Fixing Commit Messages
|
||||
|
||||
### Edit Last Commit Message
|
||||
|
||||
```bash
|
||||
git commit --amend -m "new commit message"
|
||||
```
|
||||
|
||||
### Edit Last Commit Message in Editor
|
||||
|
||||
```bash
|
||||
git commit --amend
|
||||
```
|
||||
|
||||
### Edit Older Commit Messages
|
||||
|
||||
```bash
|
||||
git rebase -i HEAD~3 # Edit last 3 commits
|
||||
# Change "pick" to "reword" for commits to edit
|
||||
```
|
||||
|
||||
⚠️ **Warning**: Never amend or rebase commits that have been pushed to shared branches!
|
||||
|
||||
## Language-Specific Considerations
|
||||
|
||||
### Go Projects
|
||||
```
|
||||
feat(http): add middleware for request logging
|
||||
refactor(db): migrate from database/sql to sqlx
|
||||
fix(parser): handle edge case in JSON unmarshaling
|
||||
```
|
||||
|
||||
### JavaScript/TypeScript Projects
|
||||
```
|
||||
feat(components): add error boundary component
|
||||
fix(hooks): prevent infinite loop in useEffect
|
||||
chore(deps): upgrade React to 18.3.0
|
||||
```
|
||||
|
||||
### Python Projects
|
||||
```
|
||||
feat(api): add FastAPI endpoint for user registration
|
||||

|
||||
```
|
||||
|
||||
## Common Pitfalls and Solutions
|
||||
|
||||
| Pitfall | Solution |
|
||||
|---------|----------|
|
||||
| Forgetting to commit | Set reminders, commit frequently |
|
||||
| Vague messages | Include specific details about what changed |
|
||||
| Too many changes in one commit | Break into atomic commits |
|
||||
| Past tense usage | Use imperative mood |
|
||||
| Missing issue references | Always link to tracking system |
|
||||
| Not explaining "why" | Add body explaining motivation |
|
||||
| Inconsistent formatting | Use commitlint or pre-commit hooks |
|
||||
|
||||

## Summary
|
||||
|
||||
**The 7 Rules of Great Commit Messages**:
|
||||
|
||||
1. Use conventional commit format: `type(scope): subject`
|
||||
2. Limit subject line to 50 characters
|
||||
3. Use imperative mood: "Add" not "Added"
|
||||
4. Don't end subject with punctuation
|
||||
5. Separate subject from body with blank line
|
||||
6. Wrap body at 72 characters
|
||||
7. Explain what and why, not how
|
||||
|
||||
**Remember**: A great commit message helps your future self and your team understand the evolution of the codebase. Write commit messages that you'd want to read when debugging at 2 AM! 🕑

- **Text Content**: Use `toHaveText` for exact text matches and `toContainText` for partial matches.

- **Switch States**: Use `expectSwitchState(locator, boolean)` to verify toggle states. This is more reliable than `toBeChecked()` directly.
|
||||
|
||||
### Switch/Toggle Interaction Patterns
|
||||
|
||||
Switch components use a hidden `<input>` with styled siblings, requiring special handling:
|
||||
|
||||
```typescript
|
||||
import { clickSwitch, expectSwitchState, toggleSwitch } from './utils/ui-helpers';
|
||||
|
||||
// ✅ RECOMMENDED: Click switch with helper
|
||||
const aclSwitch = page.getByRole('switch', { name: /acl/i });
|
||||
await clickSwitch(aclSwitch);
|
||||
|
||||
// ✅ RECOMMENDED: Assert switch state
|
||||
await expectSwitchState(aclSwitch, true); // Checked
|
||||
|
||||
// ✅ RECOMMENDED: Toggle and verify state change
|
||||
const newState = await toggleSwitch(aclSwitch);
|
||||
console.log(`Switch is now ${newState ? 'enabled' : 'disabled'}`);
|
||||
|
||||
// ❌ AVOID: Direct click on hidden input
|
||||
await aclSwitch.click(); // May fail in WebKit/Firefox
|
||||
|
||||
// ❌ AVOID: Force clicking (anti-pattern)
|
||||
await aclSwitch.click({ force: true }); // Bypasses real user behavior
|
||||
|
||||
// ❌ AVOID: Hard-coded waits
|
||||
await page.waitForTimeout(500); // Non-deterministic, slows tests
|
||||
```
|
||||
|
||||
**When to Use**:
|
||||
- Settings pages with enable/disable toggles
|
||||
- Security dashboard module switches (CrowdSec, ACL, WAF, Rate Limiting)
|
||||
- Access lists and configuration toggles
|
||||
- Any UI component using the `Switch` primitive from shadcn/ui

- Builds the latest Docker image with your code changes
|
||||
- Starts the `charon-e2e` container with proper environment variables from `.env`
|

- Exposes required ports: 8080 (app), 2020 (emergency), 2019 (Caddy admin)
|

- Waits for health check to pass
