Use Playwright’s page.screenshot() after opening your running React app. By default, it saves the visible viewport; set fullPage: true for the full scrollable page, or take a locator screenshot to capture one component. The key to a useful capture is waiting for an app-specific sign that the content is ready.
Install Playwright and capture a running React app
This example assumes your React site is already running at http://localhost:3000. Change the URL to match your development server. Playwright’s Page API works with the running website; the official API documentation does not prescribe a React-specific capture recipe.

Save the following as
screenshot.jsand run it withnode screenshot.js.
const { chromium } = require('playwright');
(async () => {
const browser = await chromium.launch();
try {
const page = await browser.newPage();
await page.goto('http://localhost:3000');
await page.screenshot({ path: 'screenshot.png' });
} finally {
await browser.close();
}
})();The image is written to screenshot.png in the current working directory. This is a one-off capture, not a test assertion. See the Playwright Page API for current navigation and screenshot options.
Wait for the React content you need
A page navigation event does not guarantee that client-rendered content, data, or a particular component is ready. Wait for a meaningful app-specific element before capturing it. For example, if the page’s main heading is rendered when the view is ready:
await page.goto('http://localhost:3000');
await page.getByRole('heading', { name: 'Dashboard' }).waitFor();
await page.screenshot({ path: 'dashboard.png' });Replace the heading and text with a reliable signal from your own app. Playwright discourages using networkidle as a test-readiness condition: a quiet network does not prove the UI is ready, and a page can keep network connections open. Fixed waits such as waitForTimeout() are intended for debugging, not as a dependable readiness strategy. Prefer a locator or assertion tied to the state you need. See Playwright’s navigation and waiting guidance.

Choose what the screenshot includes
Visible viewport or full scrollable page
page.screenshot() captures the current viewport by default. To include the page’s full scrollable content, set fullPage: true:
await page.screenshot({ path: 'full-page.png', fullPage: true });A full-page capture can be much taller than a typical screen image. Use it for documentation or an overview of a long page; use the default viewport capture when you need to inspect a particular screen-sized state. See the Playwright screenshots guide.
Whole page or one component
To save only an element, take a screenshot from a locator:
await page.locator('.header').screenshot({ path: 'header.png' });Choose a selector that identifies the intended component unambiguously. Locator screenshots are useful for isolating a header, card, chart, or other part of a React page instead of including the surrounding layout. The ElementHandle API and Page API document screenshot methods and options.

Image format, clipping, and background
The output path extension determines the screenshot format; Playwright’s screenshot API also supports options such as a clip region, image quality, and background handling. Check the current Page API for the exact option behavior and defaults before relying on them in a script, since API details can change.
CSS-pixel size or device-pixel detail
The scale option controls screenshot pixel dimensions. scale: 'css' produces one image pixel per CSS pixel; scale: 'device' uses device pixels and can produce a substantially larger image on a high-DPI context:
await page.screenshot({ path: 'css-scale.png', scale: 'css' });
await page.screenshot({ path: 'device-scale.png', scale: 'device' });Use CSS scaling when compact output is more important than device-pixel detail. Use device scaling when that additional detail is needed, accounting for the larger image dimensions. See the Page API’s scale option.

import { test, expect } from '@playwright/test';

await page.goto('http://localhost:3000');
await page.getByRole('heading', { name: 'Dashboard' }).waitFor();
await expect(page).toHaveScreenshot('dashboard.png');
});Playwright waits for two consecutive page screenshots to match before comparing, which can help avoid taking a baseline from a frame that is still changing. Keep baseline creation and comparison on the same browser and execution environment where possible. Rendering can differ with the host operating system, browser version, settings, hardware, power source, or headless mode; an image diff is not automatically evidence of an application regression.

-
A visual test fails on another machine: compare browser and host environment differences before treating the result as a UI change. Keep baseline generation and test runs consistent.
-
A fixed delay works inconsistently: replace it with a wait for the specific UI state that matters. Arbitrary sleeps and network-idle assumptions do not reliably establish that a React view is ready.
