Capabilities

Playwright is built to automate the broad and growing set of web browser capabilities used by Single Page Apps and Progressive Web Apps.

  • Scenarios that span multiple page, domains and iframes
  • Auto-wait for elements to be ready before executing actions (like click, fill)
  • Intercept network activity for stubbing and mocking network requests
  • Emulate mobile devices, geolocation, permissions
  • Support for web components via shadow-piercing selectors
  • Native input events for mouse and keyboard
  • Upload and download files

Example

The following example crawls the current top voted items from Hacker News.

package main

import (
	"fmt"
	"log"

	"github.com/mxschmitt/playwright-go"
)

func main() {
	pw, err := playwright.Run()
	if err != nil {
		log.Fatalf("could not start playwright: %v", err)
	}
	browser, err := pw.Chromium.Launch()
	if err != nil {
		log.Fatalf("could not launch browser: %v", err)
	}
	page, err := browser.NewPage()
	if err != nil {
		log.Fatalf("could not create page: %v", err)
	}
	if _, err = page.Goto("https://news.ycombinator.com"); err != nil {
		log.Fatalf("could not goto: %v", err)
	}
	entries, err := page.QuerySelectorAll(".athing")
	if err != nil {
		log.Fatalf("could not get entries: %v", err)
	}
	for i, entry := range entries {
		titleElement, err := entry.QuerySelector("td.title > a")
		if err != nil {
			log.Fatalf("could not get title element: %v", err)
		}
		title, err := titleElement.TextContent()
		if err != nil {
			log.Fatalf("could not get text content: %v", err)
		}
		fmt.Printf("%d: %s\n", i+1, title)
	}
	if err = browser.Close(); err != nil {
		log.Fatalf("could not close browser: %v", err)
	}
	if err = pw.Stop(); err != nil {
		log.Fatalf("could not stop Playwright: %v", err)

Functions

func Bool 

func Bool(v bool) *bool

Bool is a helper routine that allocates a new bool value to store v and returns a pointer to it.

func Float 

func Float(v float64) *float64

Float is a helper routine that allocates a new float64 value to store v and returns a pointer to it.

func Install 

func Install(options ...*RunOptions) error

Install does download the driver and the browsers. If not called manually before playwright.Run() it will get executed there and might take a few seconds to download the Playwright suite.

func Int 

func Int(v int) *int

Int is a helper routine that allocates a new int32 value to store v and returns a pointer to it.

func Null 

func Null() interface{}

Null will be used in certain scenarios where a strict nil pointer check is not possible

func String 

func String(v string) *string

String is a helper routine that allocates a new string value to store v and returns a pointer to it.

Types

type AccessibilitySnapshotOptions 

type AccessibilitySnapshotOptions struct {
	InterestingOnly *bool          `json:"interestingOnly"`
	Root            *ElementHandle `json:"root"`
}

type BindingCall 

type BindingCall interface {
	Call(f BindingCallFunction)
}

type BindingCallFunction added in v0.171.1 

type BindingCallFunction = func(source *BindingSource, args ...interface{}) interface{}

type BindingSource added in v0.171.1 

type BindingSource struct {
	Context BrowserContext
	Page    Page
	Frame   Frame
}

type Browser 

type Browser interface {
	EventEmitter
	// In case this browser is obtained using browserType.launch([options]), closes the browser and all of its pages (if any were
	// opened).
	// In case this browser is obtained using browserType.connect(params), clears all created contexts belonging to this browser
	// and disconnects from the browser server.
	// The Browser object itself is considered to be disposed and cannot be used anymore.
	Close() error
	// Returns an array of all open browser contexts. In a newly created browser, this will return zero browser contexts.
	Contexts() []BrowserContext
	// Indicates that the browser is connected.
	IsConnected() bool
	// Creates a new browser context. It won't share cookies/cache with other browser contexts.
	NewContext(options ...BrowserNewContextOptions) (BrowserContext, error)
	// Creates a new page in a new browser context. Closing this page will close the context as well.
	// This is a convenience API that should only be used for the single-page scenarios and short snippets. Production code and
	// testing frameworks should explicitly create browser.newContext([options]) followed by the browserContext.newPage() to
	// control their exact life times.
	NewPage(options ...BrowserNewContextOptions) (Page, error)
	// Returns the browser version.
	Version() string
}

A Browser is created when Playwright connects to a browser instance, either through browserType.launch([options]) or browserType.connect(params). An example of using a Browser to create a Page: See ChromiumBrowser, FirefoxBrowser and WebKitBrowser for browser-specific features. Note that browserType.connect(params) and browserType.launch([options]) always return a specific browser instance, based on the browser being connected to or launched.

type BrowserContext 

type BrowserContext interface {
	EventEmitter
	// Adds cookies into this browser context. All pages within this context will have these cookies installed. Cookies can be
	// obtained via browserContext.cookies([urls]).
	AddCookies(cookies ...SetNetworkCookieParam) error
	// Adds a script which would be evaluated in one of the following scenarios:
	// Whenever a page is created in the browser context or is navigated.
	// Whenever a child frame is attached or navigated in any page in the browser context. In this case, the script is evaluated in the context of the newly attached frame.
	// The script is evaluated after the document was created but before any of its scripts were run. This is useful to amend
	// the JavaScript environment, e.g. to seed `Math.random`.
	// An example of overriding `Math.random` before the page loads:
	// **NOTE** The order of evaluation of multiple scripts installed via browserContext.addInitScript(script[, arg]) and
	// page.addInitScript(script[, arg]) is not defined.
	AddInitScript(options BrowserContextAddInitScriptOptions) error
	// Returns the browser instance of the context. If it was launched as a persistent context null gets returned.
	Browser() Browser
	// Clears context cookies.
	ClearCookies() error
	// Clears all permission overrides for the browser context.
	ClearPermissions() error
	// Closes the browser context. All the pages that belong to the browser context will be closed.
	// **NOTE** the default browser context cannot be closed.
	Close() error
	// If no URLs are specified, this method returns all cookies. If URLs are specified, only cookies that affect those URLs
	// are returned.
	Cookies(urls ...string) ([]*NetworkCookie, error)
	ExpectEvent(event string, cb func() error) (interface{}, error)
	// The method adds a function called `name` on the `window` object of every frame in every page in the context. When
	// called, the function executes `playwrightBinding` in Node.js and returns a Promise which resolves to the return value
	// of `playwrightBinding`. If the `playwrightBinding` returns a Promise, it will be awaited.
	// The first argument of the `playwrightBinding` function contains information about the caller: `{ browserContext: BrowserContext, page: Page, frame: Frame }`.
	// See page.exposeBinding(name, playwrightBinding[, options]) for page-only version.
	// An example of exposing page URL to all frames in all pages in the context:
	// An example of passing an element handle:
	ExposeBinding(name string, binding BindingCallFunction, handle ...bool) error
	// The method adds a function called `name` on the `window` object of every frame in every page in the context. When
	// called, the function executes `playwrightFunction` in Node.js and returns a Promise which resolves to the return value
	// of `playwrightFunction`.
	// If the `playwrightFunction` returns a Promise, it will be awaited.
	// See page.exposeFunction(name, playwrightFunction) for page-only version.
	// An example of adding an `md5` function to all pages in the context:
	ExposeFunction(name string, binding ExposedFunction) error
	// Grants specified permissions to the browser context. Only grants corresponding permissions to the given origin if
	// specified.
	GrantPermissions(permissions []string, options ...BrowserContextGrantPermissionsOptions) error
	// Creates a new page in the browser context.
	NewPage(options ...BrowserNewPageOptions) (Page, error)
	// Returns all open pages in the context. Non visible pages, such as `"background_page"`, will not be listed here. You can
	// find them using chromiumBrowserContext.backgroundPages().
	Pages() []Page
	// This setting will change the default maximum navigation time for the following methods and related shortcuts:
	// page.goBack([options])
	// page.goForward([options])
	// page.goto(url[, options])
	// page.reload([options])
	// page.setContent(html[, options])
	// page.waitForNavigation([options])
	// **NOTE** page.setDefaultNavigationTimeout(timeout) and page.setDefaultTimeout(timeout) take priority over
	// browserContext.setDefaultNavigationTimeout(timeout).
	SetDefaultNavigationTimeout(timeout int)
	// This setting will change the default maximum time for all the methods accepting `timeout` option.
	// **NOTE** page.setDefaultNavigationTimeout(timeout), page.setDefaultTimeout(timeout) and
	// browserContext.setDefaultNavigationTimeout(timeout) take priority over browserContext.setDefaultTimeout(timeout).
	SetDefaultTimeout(timeout int)
	// The extra HTTP headers will be sent with every request initiated by any page in the context. These headers are merged
	// with page-specific extra HTTP headers set with page.setExtraHTTPHeaders(headers). If page overrides a particular header,
	// page-specific header value will be used instead of the browser context header value.
	// **NOTE** `browserContext.setExtraHTTPHeaders` does not guarantee the order of headers in the outgoing requests.
	SetExtraHTTPHeaders(headers map[string]string) error
	// Sets the context's geolocation. Passing `null` or `undefined` emulates position unavailable.
	// **NOTE** Consider using browserContext.grantPermissions(permissions[, options]) to grant permissions for the browser context pages to
	// read its geolocation.
	SetGeolocation(gelocation *SetGeolocationOptions) error
	ResetGeolocation() error
	// Routing provides the capability to modify network requests that are made by any page in the browser context. Once route
	// is enabled, every request matching the url pattern will stall unless it's continued, fulfilled or aborted.
	// An example of a naïve handler that aborts all image requests:
	// or the same snippet using a regex pattern instead:
	// Page routes (set up with page.route(url, handler)) take precedence over browser context routes when request matches both
	// handlers.
	// **NOTE** Enabling routing disables http cache.
	Route(url interface{}, handler routeHandler) error
	SetOffline(offline bool) error
	// Removes a route created with browserContext.route(url, handler). When `handler` is not specified, removes all routes for the
	// `url`.
	Unroute(url interface{}, handler routeHandler) error
	// Waits for event to fire and passes its value into the predicate function. Resolves when the predicate returns truthy
	// value. Will throw an error if the context closes before the event is fired. Returns the event data value.
	WaitForEvent(event string, predicate ...interface{}) interface{}
}

BrowserContexts provide a way to operate multiple independent browser sessions. If a page opens another page, e.g. with a `window.open` call, the popup will belong to the parent page's browser context. Playwright allows creation of "incognito" browser contexts with `browser.newContext()` method. "Incognito" browser contexts don't write any browsing data to disk.

	// **Chromium-only** Playwright can also be used to control the Chrome browser, but it works best with the version of
	// Chromium it is bundled with. There is no guarantee it will work with any other version. Use `executablePath` option with
	// extreme caution.
	// If Google Chrome (rather than Chromium) is preferred, a Chrome
	// Canary or Dev
	// Channel build is suggested.
	// In browserType.launch([options]) above, any mention of Chromium also applies to Chrome.
	// See `this article` for
	// a description of the differences between Chromium and Chrome. `This article` describes
	// some differences for Linux users.
	Launch(options ...BrowserTypeLaunchOptions) (Browser, error)
	// Returns the persistent browser context instance.
	// Launches browser that uses persistent storage located at `userDataDir` and returns the only context. Closing this
	// context will automatically close the browser.
	LaunchPersistentContext(userDataDir string, options ...BrowserTypeLaunchPersistentContextOptions) (BrowserContext, error)
	// Returns browser name. For example: `'chromium'`, `'webkit'` or `'firefox'`.
	Name() string

	SuggestedFilename() string
	// Returns downloaded url.
	URL() string
}

Download objects are dispatched by page via the page.on('download') event. All the downloaded files belonging to the browser context are deleted when the browser context is closed. All downloaded files are deleted when the browser closes. Download event is emitted once the download starts. Download path becomes available once download completes: **NOTE** Browser context **must** be created with the `acceptDownloads` set to `true` when user needs access to the downloaded content. If `acceptDownloads` is not set or set to `false`, download events are emitted, but the actual download is not performed and user has no access to the downloaded files.

type ElementHandle 

type ElementHandle interface {
	JSHandle
	// This method returns the bounding box of the element, or `null` if the element is not visible. The bounding box is
	// calculated relative to the main frame viewport - which is usually the same as the browser window.
	// Scrolling affects the returned bonding box, similarly to
	// Element.getBoundingClientRect. That
	// means `x` and/or `y` may be negative.
	// Elements from child frames return the bounding box relative to the main frame, unlike the
	// Element.getBoundingClientRect.
	// Assuming the page is static, it is safe to use bounding box coordinates to perform input. For example, the following
	// snippet should click the center of the element.
	BoundingBox() (*Rect, error)
	// This method checks the element by performing the following steps:

	// Scroll the element into view if needed.
	// Use page.mouse to click in the center of the element.

	ContentFrame() (Frame, error)
	// This method double clicks the element by performing the following steps:
	// Wait for actionability checks on the element, unless `force` option is set.
	// Scroll the element into view if needed.

	// Wait for initiated navigations to either succeed or fail, unless `noWaitAfter` option is set. Note that if the first click of the `dblclick()` triggers a navigation event, this method will reject.
	// If the element is detached from the DOM at any moment during the action, this method rejects.
	// When all steps combined have not finished during the specified `timeout`, this method rejects with a TimeoutError.
	// Passing zero timeout disables this.
	// **NOTE** `elementHandle.dblclick()` dispatches two `click` events and a single `dblclick` event.
	Dblclick(options ...ElementHandleDblclickOptions) error
	// The snippet below dispatches the `click` event on the element. Regardless of the visibility state of the elment, `click`
	// is dispatched. This is equivalend to calling
	// element.click().
	// Under the hood, it creates an instance of an event based on the given `type`, initializes it with `eventInit` properties
	// and dispatches it on the element. Events are `composed`, `cancelable` and bubble by default.
	// Since `eventInit` is event-specific, please refer to the events documentation for the lists of initial properties:
	// DragEvent
	// FocusEvent
	// KeyboardEvent
	// MouseEvent
	// PointerEvent
	// TouchEvent
	// Event
	// You can also specify `JSHandle` as the property value if you want live objects to be passed into the event:
	DispatchEvent(typ string, initObjects ...interface{}) error
	// Returns the return value of `pageFunction`
	// The method finds an element matching the specified selector in the `ElementHandle`s subtree and passes it as a first
	// argument to `pageFunction`. See Working with selectors for more details. If no elements match

	// Holding down `Shift` will type the text that corresponds to the `key` in the upper case.
	// If `key` is a single character, it is case-sensitive, so the values `a` and `A` will generate different respective

ElementHandle represents an in-page DOM element. ElementHandles can be created with the page.$(selector) method. ElementHandle prevents DOM element from garbage collection unless the handle is disposed with jsHandle.dispose(). ElementHandles are auto-disposed when their origin frame gets navigated. ElementHandle instances can be used as an argument in page.$eval(selector, pageFunction[, arg]) and page.evaluate(pageFunction[, arg]) methods.

At every point of time, page exposes its current frame tree via the page.mainFrame() and frame.childFrames() methods. Frame object's lifecycle is controlled by three events, dispatched on the page object: page.on('frameattached') - fired when the frame gets attached to the page. A Frame can be attached to the page only once. page.on('framenavigated') - fired when the frame commits navigation to a different URL. page.on('framedetached') - fired when the frame gets detached from the page. A Frame can be detached from the page only once. An example of dumping frame tree: An example of getting text from an iframe element:

	// Returns the return value of `pageFunction` as in-page object (JSHandle).
	// This method passes this handle as the first argument to `pageFunction`.
	// The only difference between `jsHandle.evaluate` and `jsHandle.evaluateHandle` is that `jsHandle.evaluateHandle` returns
	// in-page object (JSHandle).
	// If the function passed to the `jsHandle.evaluateHandle` returns a Promise, then `jsHandle.evaluateHandle` would wait

JSHandle represents an in-page JavaScript object. JSHandles can be created with the page.evaluateHandle(pageFunction[, arg]) method. JSHandle prevents the referenced JavaScript object being garbage collected unless the handle is exposed with jsHandle.dispose(). JSHandles are auto-disposed when their origin frame gets navigated or the parent context gets destroyed. JSHandle instances can be used as an argument in page.$eval(selector, pageFunction[, arg]), page.evaluate(pageFunction[, arg]) and page.evaluateHandle(pageFunction[, arg]) methods.

Keyboard provides an api for managing a virtual keyboard. The high level api is keyboard.type(text[, options]), which takes raw characters and generates proper keydown, keypress/input, and keyup events on your page. For finer control, you can use keyboard.down(key), keyboard.up(key), and keyboard.insertText(text) to manually fire events as if they were generated from a real keyboard.

Page provides methods to interact with a single tab in a Browser, or an extension background page in Chromium. One Browser instance might have multiple Page instances. This example creates a page, navigates it to a URL, and then saves a screenshot: The Page class emits various events (described below) which can be handled using any of Node's native `EventEmitter` methods, such as `on`, `once` or `removeListener`. This example logs a message for a single page `load` event: To unsubscribe from events use the `removeListener` method:

type Request 

type Request interface {
	// The method returns `null` unless this request has failed, as reported by `requestfailed` event.
	// Example of logging of all the failed requests:
	Failure() *RequestFailure
	// Returns the Frame that initiated this request.
	Frame() Frame
	// An object with HTTP headers associated with the request. All header names are lower-case.
	Headers() map[string]string
	// Whether this request is driving frame's navigation.
	IsNavigationRequest() bool
	// Request's method (GET, POST, etc.)
	Method() string
	// Request's post body, if any.
	PostData() (string, error)
	// Request's post body in a binary form, if any.
	PostDataBuffer() ([]byte, error)
	// Returns parsed request's body for `form-urlencoded` and JSON as a fallback if any.
	// When the response is `application/x-www-form-urlencoded` then a key/value object of the values will be returned.
	// Otherwise it will be parsed as JSON.
	PostDataJSON(v interface{}) error
	// Request that was redirected by the server to this one, if any.
	// When the server responds with a redirect, Playwright creates a new Request object. The two requests are connected by
	// `redirectedFrom()` and `redirectedTo()` methods. When multiple server redirects has happened, it is possible to
	// construct the whole redirect chain by repeatedly calling `redirectedFrom()`.
	// For example, if the website `http://example.com` redirects to `https://example.com`:
	// If the website `https://google.com` has no redirects:
	RedirectedFrom() Request
	// New request issued by the browser if the server responded with redirect.
	// This method is the opposite of request.redirectedFrom():
	RedirectedTo() Request
	// Contains the request's resource type as it was perceived by the rendering engine. ResourceType will be one of the
	// following: `document`, `stylesheet`, `image`, `media`, `font`, `script`, `texttrack`, `xhr`, `fetch`, `eventsource`,
	// `websocket`, `manifest`, `other`.
	ResourceType() string
	// Returns the matching Response object, or `null` if the response was not received due to error.
	Response() (Response, error)
	// Returns resource timing information for given request. Most of the timing values become available upon the response,
	// `responseEnd` becomes available when request finishes. Find more information at Resource Timing
	// API.
	Timing() *ResourceTiming
	// URL of the request.
	URL() string
}

Whenever the page sends a request for a network resource the following sequence of events are emitted by Page: page.on('request') emitted when the request is issued by the page. page.on('response') emitted when/if the response status and headers are received for the request. page.on('requestfinished') emitted when the response body is downloaded and the request is complete. If request fails at some point, then instead of `'requestfinished'` event (and possibly instead of 'response' event), the page.on('requestfailed') event is emitted. **NOTE** HTTP Error responses, such as 404 or 503, are still successful responses from HTTP standpoint, so request will complete with `'requestfinished'` event. If request gets a 'redirect' response, the request is successfully finished with the 'requestfinished' event, and a new request is issued to a redirected url.

	Ok() bool
	// Returns the matching Request object.
	Request() Request
	// Contains the status code of the response (e.g., 200 for a success).
	Status() int
	// Contains the status text of the response (e.g. usually an "OK" for a success).
	StatusText() string
	// Returns the text representation of response body.
	Text() (string, error)

	Accuracy  *int `json:"accuracy"`
}

type SetNetworkCookieParam 

type SetNetworkCookieParam struct {
	Name     string  `json:"name"`
	Value    string  `json:"value"`
	URL      *string `json:"url"`
	Domain   *string `json:"domain"`
	Path     *string `json:"path"`
	Expires  *int    `json:"expires"`
	HttpOnly *bool   `json:"httpOnly"`
	Secure   *bool   `json:"secure"`
	SameSite *string `json:"sameSite"`
}

type TimeoutError 

type TimeoutError Error

func (*TimeoutError) Error 

func (e *TimeoutError) Error() string

type Touchscreen added in v0.171.1 

type Touchscreen interface {
	// Dispatches a `touchstart` and `touchend` event with a single touch at the position (`x`,`y`).
	Tap(x int, y int) error
}

The Touchscreen class operates in main-frame CSS pixels relative to the top-left corner of the viewport. Methods on the touchscreen can only be used in browser contexts that have been intialized with `hasTouch` set to true.

type Video 

type Video interface {
	// Returns the file system path this video will be recorded to. The video is guaranteed to be written to the filesystem
	// upon closing the browser context.
	Path() string
}

When browser context is created with the `videosPath` option, each page has a video object associated with it.

type ViewportSize 

type ViewportSize struct {
	Width  int `json:"width"`
	Height int `json:"height"`
}

type WebSocket 

type WebSocket interface {
	EventEmitter
	// Indicates that the web socket has been closed.
	IsClosed() bool
	// Contains the URL of the WebSocket.
	URL() string
	// Returns the event data value.
	// Waits for event to fire and passes its value into the predicate function. Resolves when the predicate returns truthy
	// value. Will throw an error if the webSocket is closed before the event is fired.
	WaitForEvent(event string, predicate ...interface{}) interface{}
}

The WebSocket class represents websocket connections in the page.

type WebSocketWaitForEventOptions 

type WebSocketWaitForEventOptions struct {
	Predicate interface{} `json:"predicate"`
	Timeout   *int        `json:"timeout"`
}

type Worker 

type Worker interface {
	EventEmitter
	// Returns the return value of `pageFunction`
	// If the function passed to the `worker.evaluate` returns a Promise, then `worker.evaluate` would wait for the promise
	// to resolve and return its value.
	// If the function passed to the `worker.evaluate` returns a non-Serializable value, then `worker.evaluate` resolves to
	// `undefined`. DevTools Protocol also supports transferring some additional values that are not serializable by `JSON`:
	// `-0`, `NaN`, `Infinity`, `-Infinity`, and bigint literals.
	Evaluate(expression string, options ...interface{}) (interface{}, error)
	// Returns the return value of `pageFunction` as in-page object (JSHandle).
	// The only difference between `worker.evaluate` and `worker.evaluateHandle` is that `worker.evaluateHandle` returns
	// in-page object (JSHandle).
	// If the function passed to the `worker.evaluateHandle` returns a Promise, then `worker.evaluateHandle` would wait for
	// the promise to resolve and return its value.
	EvaluateHandle(expression string, options ...interface{}) (JSHandle, error)
	URL() string
	WaitForEvent(event string, predicate ...interface{}) interface{}
	ExpectEvent(event string, cb func() error, predicates ...interface{}) (interface{}, error)
}

The Worker class represents a WebWorker. `worker` event is emitted on the page object to signal a worker creation. `close` event is emitted on the worker object when the worker is gone.
