  Highlights

  There is no extra window when launching in headful mode.

  0️⃣ Default viewport has been changed from 800x600 to 1280x720.

  👷 Published recipes for popular CI environments.

  📚 Playwright now includes a carefully crafted index.d.ts file with documentation inlined from api.md. Any type-related issues are welcome.

  💻 Many APIs are now available on browser context, for example browserContext.route(url, handler). This makes it easier to setup context once and ensure that all pages and popups behave consistently.

  0️⃣ Many actions (for example, page.click(selector[, options]) or page.evaluate(pageFunction[, arg])) by default wait before and after performing an action to facilitate linear workflow.

  • Before action: input actions like click or fill wait for the element to be present in the dom, displayed, stop moving and receive pointer events. This behavior can be disabled by passing {force: true} option.
  • After action: many actions wait for any triggered navigations to finish. Option waitUntil determines the "navigation finished" condition, for example load or domcontentloaded.

  This change eliminates the need for explicit waits:

  // Waits for the link to be present and clickable,// clicks it and waits for the navigation to finish.await page.click('a');// Ready to use.console.log(await page.title());
  

  Previously, it was necessary to wait for preconditions and postconditions to avoid flakiness:

  // Waits for the link to be present.// Not needed anymore.await page.waitForSelector('a');await Promise.all([// Waits for the triggered navigation to finish.// Not needed anymore.page.waitForNavigation(), // Clicks the link.page.click('a'),]);// Ready to use.console.log(await page.title());
  

  📄 Evaluation functions (for example, page.evaluate(pageFunction[, arg])) now accept nested handles inside objects/arrays, but only take a single argument.

  const x = await page.evaluateHandle(() =\> window.scrollX);const y = await page.evaluateHandle(() =\> window.scrollY);// Old style, does not work anymore:await page.evaluate((x, y) =\> x + y, x, y);// New style, passing an object:await page.evaluate(({x, y}) =\> x + y, {x, y});// New style, passing an array:await page.evaluate(([x, y]) =\> x + y, [x, y]);// New style, passing arbitrary object structure with handles inside:await page.evaluate(({ scrollOffset }) =\> scrollOffset.x + scrollOffset.y, { scrollOffset: { x, y }});
  

  💥 Breaking API Changes

  💻 BrowserContext

  • browserContext.setCookies() is renamed to browserContext.addCookies(cookies).

  - browserContext.setPermissions() is renamed to browserContext.grantPermissions(permissions[, options]) and grants additional permissions instead of overriding entire permissions list.

  💻 BrowserType

  • browserType.devices is removed.
  • browserType.downloadBrowserIfNeeded() is removed.
  • browserType.errors is removed.

  - browserType.launchPersistent() is renamed to browserType.launchPersistentContext(userDataDir[, options]).

  ChromiumTarget

  • ChromiumTarget, related events and methods are removed. Use browserContext.on('page'), chromiumBrowserContext.on('backgroundpage') and chromiumBrowserContext.on('serviceworker').

  - chromiumTarget.createCDPSession is moved to chromiumBrowserContext.newCDPSession(page).

  ElementHandle

  • elementHandle.click({relativePoint}) - relativePoint is renamed to position.
  • elementHandle.click({clickCount}) - clickCount now clicks multiple times, instead of producing a single event with a clickCount property.
  • elementHandle.select() is renamed to elementHandle.selectOption(values[, options]).
  • elementHandle.tripleclick() is removed.

  - elementHandle.visibleRatio() is removed.

  Frame

  • frame.click(selector, {relativePoint}) - relativePoint is renamed to position.
  • frame.click(selector, {clickCount}) - clickCount now clicks multiple times, instead of producing a single event with a clickCount property.
  • frame.select() is renamed to frame.selectOption(selector, values[, options]).
  • frame.tripleclick() is removed.

  - frame.waitForLoadState([state[, options]]) now takes a separate state parameter.

  Keyboard

  - keyboard.sendCharacters() is renamed to keyboard.insertText(text).

  Page

  • page.on('workercreated') is renamed to page.on('worker').
  • page.on('workerdestroyed') is moved to worker.on('close').
  • page.click(selector, {relativePoint}) - relativePoint is renamed to position.
  • page.click(selector, {clickCount}) - clickCount now clicks multiple times, instead of producing a single event with a clickCount property.
  • page.evaluateOnNewDocument() is renamed to page.addInitScript(script[, arg]).
  • page.route(url, handler) handler function now accepts two parameters: Route and Request. Routing methods abort, continue and fulfill are only available on the Route class.
  • page.select() is renamed to page.selectOption(selector, values[, options]).
  • page.tripleclick() is removed.

  - page.waitForLoadState([state[, options]]) now takes a separate state parameter.

  Request

  - request.redirectChain() is replaced with request.redirectedFrom() and request.redirectedTo().

  Response

  - response.buffer() is renamed to response.body().

  Selectors

  • selectors.register(name, script) now requires a name parameter.

  🆕 New APIs

  💻 BrowserContext

  • browserContext.setExtraHTTPHeaders(headers) allows to specify additional HTTP headers to be sent with every request in every page in the browser context.
  • browserContext.setHTTPCredentials(httpCredentials) allows to handle HTTP authentication.
  • browserContext.addInitScript(script[, arg]) allows to add a script to be evaluated in all frames of all pages in the browser context before the frame loads.
  • browserContext.exposeFunction(name, playwrightFunction) allows to expose a function which can be called from any page in the browser context.
  • browserContext.route(url, handler) allows to intercept certain network requests from all pages in the browser context.
  • browserContext.setOffline(offline) emulates being offline.
  • browserContext.grantPermissions(permissions[, options]) and browser.newContext([options]) permissions option can omit origin to grant permissions to all origins.

  - browserContext.on('page') event is emitted when a new page is opened in the browser context. This allows to handle popups originated by link clicks or window.open() calls.

  Page

  • page.frame(options) finds a frame based on its name or src.
  • page.press(selector, key[, options]) is a shortcut to elementHandle.press(key[, options]).
