Screenshots
Generate marketing-quality screenshots of your app using Playwright directly. Screenshots are captured at true HiDPI (2x retina) resolution using deviceScaleFactor: 2.
When to Use This Skill
Use this skill when:
- User wants to create screenshots for Product Hunt
- Creating screenshots for social media
- Generating images for landing pages
- Creating documentation screenshots
- User requests marketing-quality app screenshots
Prerequisites
Playwright must be available. Check for it:
npx playwright --version 2>/dev/null || npm ls playwright 2>/dev/null | grep playwright
If not found, inform the user:
Playwright is required. Install it with:
npm install -D playwrightornpm install -D @playwright/test
Step 1: Determine App URL
If $1 is provided, use it as the app URL.
If no URL is provided:
- Check if a dev server is likely running by looking for
package.jsonscripts - Use
AskUserQuestionto ask the user for the URL or offer to help start the dev server
Common default URLs to suggest:
http://localhost:3000(Next.js, Create React App, Rails)http://localhost:5173(Vite)http://localhost:4000(Phoenix)http://localhost:8080(Vue CLI, generic)
Step 2: Gather Requirements
Use AskUserQuestion with the following questions:
Question 1: Screenshot count
- Header: "Count"
- Question: "How many screenshots do you need?"
- Options:
- "3-5" - Quick set of key features
- "5-10" - Comprehensive feature coverage
- "10+" - Full marketing suite
Question 2: Purpose
- Header: "Purpose"
- Question: "What will these screenshots be used for?"
- Options:
- "Product Hunt" - Hero shots and feature highlights
- "Social media" - Eye-catching feature demos
- "Landing page" - Marketing sections and benefits
- "Documentation" - UI reference and tutorials
Question 3: Authentication
- Header: "Auth"
- Question: "Does the app require login to access the features you want to screenshot?"
- Options:
- "No login needed" - Public pages only
- "Yes, I'll provide credentials" - Need to log in first
If user selects "Yes, I'll provide credentials", ask follow-up questions:
- "What is the login page URL?" (e.g.,
/login,/sign-in) - "What is the email/username?"
- "What is the password?"
The script will automatically detect login form fields using Playwright's smart locators.
Step 3: Analyze Codebase for Features
Thoroughly explore the codebase to understand the app and identify screenshot opportunities.
3.1: Read Documentation First
Always start by reading these files to understand what the app does:
-
README.md (and any README files in subdirectories) - Read the full README to understand:
- What the app is and what problem it solves
- Key features and capabilities
- Screenshots or feature descriptions already documented
-
CHANGELOG.md or HISTORY.md - Recent features worth highlighting
-
docs/ directory - Any additional documentation about features
3.2: Analyze Routes to Find Pages
Read the routing configuration to discover all available pages:
| Framework | File to Read | What to Look For |
|---|---|---|
| Next.js App Router | app/ directory structure | Each folder with page.tsx is a route |
| Next.js Pages Router | pages/ directory | Each file is a route |
| Rails | config/routes.rb | Read the entire file for all routes |
| React Router | Search for createBrowserRouter or <Route | Route definitions with paths |
| Vue Router | src/router/index.js or router.js | Routes array with path definitions |
| SvelteKit | src/routes/ directory | Each folder with +page.svelte is a route |
| Remix | app/routes/ directory | File-based routing |
| Laravel | routes/web.php | Route definitions |
| Django | urls.py files | URL patterns |
| Express | Search for app.get, router.get | Route handlers |
Important: Actually read these files, don't just check if they exist. The route definitions tell you what pages are available for screenshots.
3.3: Identify Key Components
Look for components that represent screenshottable features:
- Dashboard components
- Feature sections with distinct UI
- Forms and interactive inputs
- Data visualizations (charts, graphs, tables)
- Modals and dialogs
- Navigation and sidebars
- Settings panels
- User profile sections
3.4: Check for Marketing Assets
Look for existing marketing content that hints at key features:
- Landing page components (often in
components/landing/orcomponents/marketing/) - Feature list components
- Pricing tables
- Testimonial sections
3.5: Build Feature List
Create a comprehensive list of discovered features with:
- Feature name (from README or component name)
- URL path (from routes)
- CSS selector to focus on (from component structure)
- Required UI state (logged in, data populated, modal open, specific tab selected)
Step 4: Plan Screenshots with User
Present the discovered features to the user and ask them to confirm or modify the list.
Use AskUserQuestion:
- Header: "Features"
- Question: "I found these features in your codebase. Which would you like to screenshot?"
- Options: List 3-4 key features discovered, plus "Let me pick specific ones"
If user wants specific ones, ask follow-up questions to clarify exactly what to capture.
Step 5: Create Screenshots Directory
mkdir -p screenshots
Step 6: Generate and Run Playwright Script
Create a Node.js script that uses Playwright with proper HiDPI settings. The script should:
- Use
deviceScaleFactor: 2for true retina resolution - Set viewport to 1440x900 (produces 2880x1800 pixel images)
- Handle authentication if credentials were provided
- Navigate to each page and capture screenshots
Script Template
Write this script to a temporary file (e.g., screenshot-script.mjs) and execute it:
import { chromium } from 'playwright';
const BASE_URL = '[APP_URL]';
const SCREENSHOTS_DIR = './screenshots';
// Authentication config (if needed)
const AUTH = {
needed: [true|false],
loginUrl: '[LOGIN_URL]',
email: '[EMAIL]',
password: '[PASSWORD]',
};
// Screenshots to capture
const SCREENSHOTS = [
{ name: '01-feature-name', url: '/path', waitFor: '[optional-selector]' },
{ name: '02-another-feature', url: '/another-path' },
// ... add all planned screenshots
];
async function main() {
const browser = await chromium.launch();
// Create context with HiDPI settings
const context = await browser.newContext({
viewport: { width: 1440, height: 900 },
deviceScaleFactor: 2, // This is the key for true retina screenshots
});
const page = await context.newPage();
// Handle authentication if needed
if (AUTH.needed) {
console.log('Logging in...');
await page.goto(AUTH.loginUrl);
// Smart login: try multiple common patterns for email/username field
const emailField = page.locator([
'input[type="email"]',
'input[name="email"]',
'input[id="email"]',
'input[placeholder*="email" i]',
'input[name="username"]',
'input[id="username"]',
'input[type="text"]',
].join(', ')).first();
await emailField.fill(AUTH.email);
// Smart login: try multiple common patterns for password field
const passwordField = page.locator([
'input[type="password"]',
'input[name="password"]',
'input[id="password"]',
].join(', ')).first();
await passwordField.fill(AUTH.password);
// Smart login: try multiple common patterns for submit button
const submitButton = page.locator([
'button[type="submit"]',
'input[type="submit"]',
'button:has-text("Sign in")',
'button:has-text("Log in")',
'button:has-text("Login")',
'button:has-text("Submit")',
].join(', ')).first();
await submitButton.click();
await pa
