A free scan shows the junk files, broken settings and background clutter dragging Windows down - then fixes them in one click.Free scan · Windows 10 & 11To interact with a web page using Puppeteer, open a browser, create a Page, navigate to the site, locate the control you need, perform an action, and wait for the resulting state. For most clicks and form actions, start with Puppeteer locators: they wait for a matching element to be present and in a suitable state. The examples below follow the Puppeteer 25.12.0 Getting Started guide and use selectors you may need to adapt to your page. Puppeteer Getting Started
Set up Puppeteer and open a page
Puppeteer is a JavaScript library for browser automation. Its official overview describes automation for Chrome and Firefox through the Chrome DevTools Protocol and WebDriver BiDi. A Page represents a tab-level surface where you navigate, inspect content, and interact with elements. Chrome for Developers: Puppeteer Puppeteer Page API
Install the Puppeteer package in a JavaScript project using the installation method documented for the version you choose. The following example uses the package import shown in the official 25.12.0 Getting Started guide. It launches a browser, opens a page, navigates, and closes the browser even if an action fails:
import puppeteer from 'puppeteer';
const browser = await puppeteer.launch();
try {
const page = await browser.newPage();
await page.goto('https://example.com');
// Replace these selectors with ones that match the target page.
await page.locator('::-p-aria(Search)').fill('Puppeteer');
await page.locator('button[type="submit"]').click();
} finally {
await browser.close();
}The accessibility selector in this example expects a control whose accessible name is “Search”; the CSS selector expects a submit button. They are illustrative, not guaranteed to match example.com or another site. Inspect the target page and choose selectors that match its actual controls.

Choose a selector that expresses the target
Puppeteer supports CSS selectors as well as its own selector syntax for text, accessibility attributes, XPath, and shadow DOM. Prefer a selector that identifies the control by stable meaning where possible; use CSS when the page structure or attributes are stable. No selector form works unless the page exposes a matching element. Puppeteer Page interactions
- Accessibility name: Useful when a control has a stable accessible name, such as a search field labeled “Search.”
- Text: Useful when visible wording identifies the target, provided the wording is stable and sufficiently specific.
- CSS: Concise for stable IDs, attributes, or structure, but classes and deeply nested paths can change as a site evolves.
- XPath: Another supported choice when relationships between elements are useful to describe the target.
For interactions, use a locator rather than finding an element once and assuming it remains available. A locator resolves the target when the action is performed and automatically waits for the element to be present and in a suitable state.
Click, fill, select, and hover
Use locator actions for common user-like interactions. Replace the example selectors with those found on the page you are automating.

Click a button or link
await page.locator('button[type="submit"]').click();Enter text into a field
await page.locator('input[name="email"]').fill('person@example.com');fill() sets the field value through the locator interaction API. If the task depends on individual keystrokes or keyboard behavior, use Puppeteer’s keyboard APIs instead of treating a direct value assignment as equivalent.
Do these 3 things before closing this tab:

await page.locator('select[name="country"]').select('CA');
await page.locator('.account-menu').hover();The Page API also documents mouse, touch, and keyboard input, along with page-level click(), type(), select(), and hover() operations. Older calls such as page.click(selector) and page.type(selector, text) remain documented for backwards compatibility; locators are the current guide’s preferred default for actions.

Wait for the result, not an arbitrary delay
The right wait depends on what the action does. A link or form submission may navigate to a new document; a button may instead update part of the current page. Choose a wait condition that matches the expected result rather than adding a fixed sleep and assuming the work is done.

When a click causes navigation
Register the navigation wait before clicking. Starting the wait only after the click can miss a fast navigation and create a race:
const [response] = await Promise.all([
page.waitForNavigation(),
page.locator('a.next-page').click(),
]);Use the actual selector for the link or control. If you need to inspect the navigation response, the resolved value is available in response; navigation behavior varies by site.
When the page updates without navigation
Wait for an observable result, such as a confirmation message or a changed element:

await page.locator('button.save').click();
await page.locator('[role="status"]').wait();The status selector is an example only; choose a locator for the state your page actually exposes. Puppeteer also documents waits for selectors, functions, requests, and responses. Puppeteer Page API Puppeteer Page interactions
Read page information or inspect browser state
Use Page methods for straightforward page information, and page.evaluate() when you need to read or manipulate state in the page’s JavaScript context:
const title = await page.title();
const currentUrl = page.url();
const heading = await page.evaluate(() => document.querySelector('h1')?.textContent);Evaluation runs in the page context, so it can access the document and page JavaScript environment. For a real interaction intended to behave like user input, prefer locators and browser input methods rather than changing DOM state directly.

Verify the interaction and capture evidence
After an action, check the result that matters: the URL, visible text, a changed control state, or another page condition. A screenshot can help diagnose what rendered, but an image alone does not prove that the intended interaction succeeded.
const resultText = await page.locator('[role="status"]').textContent();
await page.screenshot({ path: 'page.png', fullPage: true });Puppeteer’s Page API also includes page.screenshot() and page.pdf(). The browser overview lists screenshots, PDFs, UI testing, and performance analysis among Puppeteer use cases. Puppeteer Page API Chrome for Developers: Puppeteer
Locators versus explicit element handles
| Approach | Waiting and retries | Lifecycle work | Best fit |
|---|---|---|---|
| Locator | Automatically waits for the target to be present and in an appropriate state for the action. | Resolves the target when the action is performed; no separate element-handle disposal in the ordinary locator flow. | Default for clicks, form entry, and other actions. |
waitForSelector() and an element handle |
Provides an explicit lower-level wait; it does not automatically retry the subsequent action if that action fails. | Dispose of element handles when finished to avoid memory leaks. | Cases needing explicit element acquisition or lower-level control. |
Puppeteer’s interactions guide recommends locators for actions and describes waitForSelector() as a lower-level option. Puppeteer Page interactions
Troubleshoot common interaction failures
- Locator does not match anything: The accessible name, text, or CSS selector may not match the rendered page. Inspect the page and choose a selector for an element that actually exists.
- Click fails or targets the wrong control: The selector may be ambiguous, or the element may not be in an actionable state. Narrow the selector and use a locator action so Puppeteer can wait for an appropriate state.
- Script continues before navigation finishes: Start
waitForNavigation()in the samePromise.all()as the click that triggers navigation. - Navigation wait never resolves after a click: The action may update the current page without a document navigation. Wait for the resulting element, state, request, or response instead.
- Page appears unchanged after an action: Verify the target state or URL rather than relying on a screenshot alone; the selector may have hit the wrong control or the page may use a different update flow.
- Memory use grows in a long-running script: If using
waitForSelector()and retaining element handles, dispose of handles when they are no longer needed.
