Rod is a high-level driver directly based on DevTools Protocol. It's designed for web automation and scraping for both high-level and low-level use, senior developers can use the low-level packages and functions to easily customize or build up their own version of Rod, the high-level functions are just examples to build a default version of Rod.

Features

  • Chained context design, intuitive to timeout or cancel the long-running task
  • Auto-wait elements to be ready
  • Debugging friendly, auto input tracing, remote monitoring headless browser
  • Thread-safe for all operations
  • Automatically find or download browser
  • Lightweight, no third-party dependencies, CI tested on Linux, Mac, and Windows
  • High-level helpers like WaitStable, WaitRequestIdle, HijackRequests, WaitDownload, etc
  • Two-step WaitEvent design, never miss an event (how it works)
  • Correctly handles nested iframes or shadow DOMs
  • No zombie browser process after the crash (how it works)

Examples

Please check the examples_test.go file first, then check the examples folder.

For more detailed examples, please search the unit tests. Such as the usage of method HandleAuth, you can search all the *_test.go files that contain HandleAuth, for example, use Github online search in repository. You can also search the GitHub issues or discussions, a lot of usage examples are recorded there.

Here is a comparison of the examples between rod and Chromedp.

Overview

Example

This example opens https://github.com/, searches for "git", and then gets the header element which gives the description for Git. 

package main

import (
	"fmt"

	"github.com/go-rod/rod"
	"github.com/go-rod/rod/lib/input"
)

func main() {
	// Launch a new browser with default options, and connect to it.
	browser := rod.New().MustConnect()

	// Even you forget to close, rod will close it after main process ends.
	defer browser.MustClose()

	// Create a new page
	page := browser.MustPage("https://github.com")

	// We use css selector to get the search input element and input "git"
	page.MustElement("input").MustInput("git").MustPress(input.Enter)

	// Wait until css selector get the element then get the text content of it.
	text := page.MustElement(".codesearch-results p").MustText()

	fmt.Println(text)

	// Get all input elements. Rod supports query elements by css selector, xpath, and regex.
	// For more detailed usage, check the query_test.go file.
	fmt.Println("Found", len(page.MustElements("input")), "input elements")

	// Eval js on the page
	page.MustEval(`console.log("hello world")`)

	// Pass parameters as json objects to the js function. This MustEval will result 3
	fmt.Println("1 + 2 =", page.MustEval(`(a, b) => a + b`, 1, 2).Int())

	// When eval on an element, "this" in the js is the current DOM element.
	fmt.Println(page.MustElement("title").MustEval(`this.innerText`).String())

}

Output:

Git is the most widely used version control system.
Found 5 input elements
1 + 2 = 3
Search · git · GitHub
Example (Context_and_timeout)

Rod use https://golang.org/pkg/context to handle cancelations for IO blocking operations, most times it's timeout. Context will be recursively passed to all sub-methods. For example, methods like Page.Context(ctx) will return a clone of the page with the ctx, all the methods of the returned page will use the ctx if they have IO blocking operations. Page.Timeout or Page.WithCancel is just a shortcut for Page.Context. Of course, Browser or Element works the same way. 

package main

import (
	"math/rand"
	"time"

	"github.com/go-rod/rod"
)

func main() {
	page := rod.New().MustConnect().MustPage("https://github.com")

	page.
		// Set a 5-second timeout for all chained methods
		Timeout(5 * time.Second).

		// The total time for MustWaitLoad and MustElement must be less than 5 seconds
		MustWaitLoad().
		MustElement("title").

		// Methods after CancelTimeout won't be affected by the 5-second timeout
		CancelTimeout().

		// Set a 10-second timeout for all chained methods
		Timeout(10 * time.Second).

		// Panics if it takes more than 10 seconds
		MustText()

	// The two code blocks below are basically the same:
	{
		page.Timeout(5 * time.Second).MustElement("a").CancelTimeout()
	}
	{
		// Use this way you can customize your own way to cancel long-running task
		page, cancel := page.WithCancel()
		go func() {
			time.Sleep(time.Duration(rand.Int())) // cancel after randomly time
			cancel()
		}()
		page.MustElement("a")
	}
}

Output:
Example (Customize_browser_launch)

Shows how we can further customize the browser with the launcher library. Usually you use launcher lib to set the browser's command line flags (switches). Doc for flags: https://peter.sh/experiments/chromium-command-line-switches 

package main

import (
	"fmt"

	"github.com/go-rod/rod"
	"github.com/go-rod/rod/lib/launcher"
)

func main() {
	url := launcher.New().
		Proxy("127.0.0.1:8080").     // set flag "--proxy-server=127.0.0.1:8080"
		Delete("use-mock-keychain"). // delete flag "--use-mock-keychain"
		MustLaunch()

	browser := rod.New().ControlURL(url).MustConnect()
	defer browser.MustClose()

	// So that we don't have to self issue certs for MITM
	browser.MustIgnoreCertErrors(true)

	// Adding authentication to the proxy, for the next auth request.
	// We use CLI tool "mitmproxy --proxyauth user:pass" as an example.
	go browser.MustHandleAuth("user", "pass")()

	// mitmproxy needs a cert config to support https. We use http here instead,
	// for example
	fmt.Println(browser.MustPage("https://example.com/").MustElement("title").MustText())
}

Output:
Example (Customize_retry_strategy)

Shows how to change the retry/polling options that is used to query elements. This is useful when you want to customize the element query retry logic. 

package main

import (
	"context"
	"errors"
	"fmt"
	"time"

	"github.com/go-rod/rod"
	"github.com/go-rod/rod/lib/utils"
)

func main() {
	browser := rod.New().MustConnect()
	defer browser.MustClose()

	page := browser.MustPage("https://github.com")

	// sleep for 0.5 seconds before every retry
	sleeper := func() utils.Sleeper {
		return func(context.Context) error {
			time.Sleep(time.Second / 2)
			return nil
		}
	}
	el, _ := page.Sleeper(sleeper).Element("input")
	fmt.Println(el.MustProperty("name"))

	// If sleeper is nil page.ElementE will query without retrying.
	// If nothing found it will return an error.
	el, err := page.Sleeper(rod.NotFoundSleeper).Element("input")
	if errors.Is(err, &rod.ErrElementNotFound{}) {
		fmt.Println("element not found")
	} else if err != nil {
		panic(err)
	}

	fmt.Println(el.MustProperty("name"))

}

Output:

Example (Direct_cdp)

When rod doesn't have a feature that you need. You can easily call the cdp to achieve it. List of cdp API: https://github.com/go-rod/rod/tree/master/lib/proto 

package main

import (
	"context"

	"github.com/go-rod/rod"
	"github.com/go-rod/rod/lib/proto"
)

func main() {
	page := rod.New().MustConnect().MustPage()

	// Rod doesn't have a method to enable AD blocking,
	// but you can call cdp interface directly to achieve it.

	// The two code blocks below are equal to enable AD blocking

	{
		_ = proto.PageSetAdBlockingEnabled{
			Enabled: true,
		}.Call(page)
	}

	{
		// Interact with the cdp JSON API directly
		_, _ = page.Call(context.TODO(), "", "Page.setAdBlockingEnabled", map[string]bool{
			"enabled": true,
		})
	}
}

Output:
Example (Disable_headless_to_debug)

Shows how to disable headless mode and debug. Rod provides a lot of debug options, you can set them with setter methods or use environment variables. Doc for environment variables: https://pkg.go.dev/github.com/go-rod/rod/lib/defaults 

package main

import (
	"fmt"
	"time"

	"github.com/go-rod/rod"
	"github.com/go-rod/rod/lib/input"
	"github.com/go-rod/rod/lib/launcher"
	"github.com/go-rod/rod/lib/utils"
)

func main() {
	// Headless runs the browser on foreground, you can also use env "rod=show"
	// Devtools opens the tab in each new tab opened automatically
	l := launcher.New().
		Headless(false).
		Devtools(true)

	defer l.Cleanup() // remove launcher.FlagUserDataDir

	url := l.MustLaunch()

	// Trace shows verbose debug information for each action executed
	// Slowmotion is a debug related function that waits 2 seconds between
	// each action, making it easier to inspect what your code is doing.
	browser := rod.New().
		ControlURL(url).
		Trace(true).
		SlowMotion(2 * time.Second).
		MustConnect()

	// ServeMonitor plays screenshots of each tab. This feature is extremely
	// useful when debugging with headless mode.
	// You can also enable it with env rod=monitor
	launcher.Open(browser.ServeMonitor(""))

	defer browser.MustClose()

	page := browser.MustPage("https://github.com/")

	page.MustElement("input").MustInput("git").MustPress(input.Enter)

	text := page.MustElement(".codesearch-results p").MustText()

	fmt.Println(text)

	utils.Pause() // pause goroutine
}

Output:
Example (Download_file) 
package main

import (
	"github.com/go-rod/rod"
	"github.com/go-rod/rod/lib/utils"
)

func main() {
	browser := rod.New().MustConnect()
	page := browser.MustPage("https://file-examples.com/index.php/sample-documents-download/sample-pdf-download/")

	wait := browser.MustWaitDownload()

	page.MustElementR("a", "DOWNLOAD SAMPLE PDF FILE").MustClick()

	_ = utils.OutputFile("t.pdf", wait())
}

Output:
Example (Error_handling)

We use "Must" prefixed functions to write example code. But in production you may want to use the no-prefix version of them. About why we use "Must" as the prefix, it's similar to https://golang.org/pkg/regexp/#MustCompile 

package main

import (
	"context"
	"errors"
	"fmt"

	"github.com/go-rod/rod"
)

func main() {
	page := rod.New().MustConnect().MustPage("https://example.com")

	// We use Go's standard way to check error types, no magic.
	check := func(err error) {
		var evalErr *rod.ErrEval
		if errors.Is(err, context.DeadlineExceeded) { // timeout error
			fmt.Println("timeout err")
		} else if errors.As(err, &evalErr) { // eval error
			fmt.Println(evalErr.LineNumber)
		} else if err != nil {
			fmt.Println("can't handle", err)
		}
	}

	// The two code blocks below are doing the same thing in two styles:

	// The block below is better for debugging or quick scripting. We use panic to short-circuit logics.
	// So that we can take advantage of fluent interface (https://en.wikipedia.org/wiki/Fluent_interface)
	// and fail-fast (https://en.wikipedia.org/wiki/Fail-fast).
	// This style will reduce code, but it may also catch extra errors (less consistent and precise).
	{
		err := rod.Try(func() {
			fmt.Println(page.MustElement("a").MustHTML()) // use "Must" prefixed functions
		})
		check(err)
	}

	// The block below is better for production code. It's the standard way to handle errors.
	// Usually, this style is more consistent and precise.
	{
		el, err := page.Element("a")
		if err != nil {
			check(err)
			return
		}
		html, err := el.HTML()
		if err != nil {
			check(err)
			return
		}
		fmt.Println(html)
	}
}

Output:
Example (Eval_reuse_remote_object)

Shows how to share a remote object reference between two Eval 

package main

import (
	"fmt"

	"github.com/go-rod/rod"
)

func main() {
	page := rod.New().MustConnect().MustPage()

	fn := page.MustEvaluate(rod.Eval(`Math.random`).ByObject())

	res := page.MustEval(`f => f()`, fn)

	// print a random number
	fmt.Println(res.Num())
}

Output:
Example (Handle_events)

Shows how to listen for events. 

package main

import (
	"fmt"

	"github.com/go-rod/rod"
	"github.com/go-rod/rod/lib/proto"
)

func main() {
	browser := rod.New().MustConnect()
	defer browser.MustClose()

	page := browser.MustPage()

	done := make(chan struct{})

	// Listen for all events of console output.
	go page.EachEvent(func(e *proto.RuntimeConsoleAPICalled) {
		fmt.Println(page.MustObjectsToJSON(e.Args))
		close(done)
	})()

	wait := page.WaitEvent(&proto.PageLoadEventFired{})
	page.MustNavigate("https://example.com")
	wait()

	// EachEvent allows us to achieve the same functionality as above.
	if false {
		// Subscribe events before they happen, run the "wait()" to start consuming
		// the events. We can return an optional stop signal to unsubscribe events.
		wait := page.EachEvent(func(e *proto.PageLoadEventFired) (stop bool) {
			return true
		})
		page.MustNavigate("https://example.com")
		wait()
	}

	// Or the for-loop style to handle events to do the same thing above.
	if false {
		page.MustNavigate("https://example.com")

		for msg := range page.Event() {
			e := proto.PageLoadEventFired{}
			if msg.Load(&e) {
				break
			}
		}
	}

	page.MustEval(`console.log("hello", "world")`)

	<-done

}

Output:

[hello world]
Example (Hijack_requests)

Shows how to intercept requests and modify both the request and the response. The entire process of hijacking one request: 

browser --req-> rod ---> server ---> rod --res-> browser

The --req-> and --res-> are the parts that can be modified. 

package main

import (
	"fmt"
	"net/http"

	"github.com/go-rod/rod"
)

func main() {
	browser := rod.New().MustConnect()
	defer browser.MustClose()

	router := browser.HijackRequests()
	defer router.MustStop()

	router.MustAdd("*.js", func(ctx *rod.Hijack) {
		// Here we update the request's header. Rod gives functionality to
		// change or update all parts of the request. Refer to the documentation
		// for more information.
		ctx.Request.Req().Header.Set("My-Header", "test")

		// LoadResponse runs the default request to the destination of the request.
		// Not calling this will require you to mock the entire response.
		// This can be done with the SetXxx (Status, Header, Body) functions on the
		// ctx.Response struct.
		_ = ctx.LoadResponse(http.DefaultClient, true)

		// Here we append some code to every js file.
		// The code will update the document title to "hi"
		ctx.Response.SetBody(ctx.Response.Body() + "\n document.title = 'hi' ")
	})

	go router.Run()

	browser.MustPage("https://go-rod.github.io").MustWait(`document.title === 'hi'`)

	fmt.Println("done")

}

Output:

done
Example (Load_extension) 
package main

import (
	"fmt"
	"path/filepath"

	"github.com/go-rod/rod"
	"github.com/go-rod/rod/lib/launcher"
)

func main() {
	extPath, _ := filepath.Abs("fixtures/chrome-extension")

	u := launcher.New().
		// Must use abs path for an extension
		Set("load-extension", extPath).
		// Headless mode doesn't support extension yet.
		// Reason: https://bugs.chromium.org/p/chromium/issues/detail?id=706008#c5
		// You can use XVFB to get rid of it: https://github.com/go-rod/rod/blob/master/lib/examples/launch-managed/main.go
		Headless(false).
		MustLaunch()

	page := rod.New().ControlURL(u).MustConnect().MustPage("http://example.com")

	page.MustWait(`document.title === 'test-extension'`)

	fmt.Println("ok")

	// Skip
	

Output:
Example (Log_cdp_traffic) 
package main

import (
	"fmt"

	"github.com/go-rod/rod"
	"github.com/go-rod/rod/lib/cdp"
	"github.com/go-rod/rod/lib/launcher"
	"github.com/go-rod/rod/lib/utils"
)

func main() {
	cdp := cdp.New(launcher.New().MustLaunch()).

		// Here we can customize how to log the requests, responses, and events transferred between Rod and the browser.
		Logger(utils.Log(func(msg ...interface{}) {
			// Such as use some fancy lib like github.com/davecgh/go-spew/spew to make the output more readable:
			//     spew.Println(msg)
			// Here we use %#v as an example.
			fmt.Printf("%#v\n", msg)
		}))

	rod.New().Client(cdp).MustConnect().MustPage("http://example.com")
}

Output:
Example (Page_pdf)

	"github.com/go-rod/rod/lib/utils"
)

func main() {
	page := rod.New().MustConnect().MustPage("https://github.com").MustWaitLoad()

	// simple version
	page.MustPDF("my.pdf")

	// customized version
	pdf, _ := page.PDF(&proto.PagePrintToPDF{
		PaperWidth:  8.5,
		PaperHeight: 11,
		PageRanges:  "1-3",
	})
	_ = utils.OutputFile("my.pdf", pdf)
}

Output:

)

func main() {
	page := rod.New().MustConnect().MustPage("https://github.com").MustWaitLoad()

	// simple version
	page.MustScreenshot("my.png")

	// customization version
	img, _ := page.Screenshot(true, &proto.PageCaptureScreenshot{
		Format:  proto.PageCaptureScreenshotFormatJpeg,
		Quality: 90,
		Clip: &proto.PageViewport{
			X:      0,
			Y:      0,
			Width:  300,
			Height: 200,
			Scale:  1,
		},
		FromSurface: true,
	})
	_ = utils.OutputFile("my.jpg", img)
}

Output:
Example (Race_selectors)

Show how to handle multiple results of an action. Such as when you login a page, the result can be success or wrong password. 

package main

import (
	"fmt"

	"github.com/go-rod/rod"
	"github.com/go-rod/rod/lib/input"
)

func main() {
	const username = ""
	const password = ""

	browser := rod.New().MustConnect()

	page := browser.MustPage("https://leetcode.com/accounts/login/")

	page.MustElement("#id_login").MustInput(username)
	page.MustElement("#id_password").MustInput(password).MustPress(input.Enter)

	// It will keep retrying until one selector has found a match
	elm := page.Race().Element(".nav-user-icon-base").MustHandle(func(e *rod.Element) {
		// print the username after successful login
		fmt.Println(*e.MustAttribute("title"))
	}).Element("[data-cy=sign-in-error]").MustDo()

	if elm.MustMatches("[data-cy=sign-in-error]") {
		// when wrong username or password
		panic(elm.MustText())
	}
}

Output:
Example (States)

Shows how to update the state of the current page. In this example we enable the network domain. 

package main

import (
	"fmt"

	"github.com/go-rod/rod"
	"github.com/go-rod/rod/lib/proto"
)

func main() {
	browser := rod.New().MustConnect()
	defer browser.MustClose()

	page := browser.MustPage()

	// LoadState detects whether the network domain is enabled or not.
	fmt.Println(page.LoadState(&proto.NetworkEnable{}))

	_ = proto.NetworkEnable{}.Call(page)

	// Check if the network domain is successfully enabled.
	fmt.Println(page.LoadState(&proto.NetworkEnable{}))

}

Output:

false
true
Example (Wait_for_animation)

Rod uses mouse cursor to simulate clicks, so if a button is moving because of animation, the click may not work as expected. We usually use WaitStable to make sure the target isn't changing anymore. 

package main

import (
	"fmt"

	"github.com/go-rod/rod"
)

func main() {
	browser := rod.New().MustConnect()
	defer browser.MustClose()

	page := browser.MustPage("https://getbootstrap.com/docs/4.0/components/modal/")

	page.MustWaitLoad().MustElement("[data-target='#exampleModalLive']").MustClick()

	saveBtn := page.MustElementR("#exampleModalLive button", "Close")

	// Here, WaitStable will wait until the button's position and size become stable.
	saveBtn.MustWaitStable().MustClick().MustWaitInvisible()

	fmt.Println("done")

}

Output:

done
Example (Wait_for_request)

When you want to wait for an ajax request to complete, this example will be useful. 

package main

import (
	"fmt"

	"github.com/go-rod/rod"
)

func main() {
	browser := rod.New().MustConnect()
	defer browser.MustClose()

	page := browser.MustPage("https://duckduckgo.com/")

	// Start to analyze request events
	wait := page.MustWaitRequestIdle()

	// This will trigger the search ajax request
	page.MustElement("#search_form_input_homepage").MustClick().MustInput("lisp")

	// Wait until there's no active requests
	wait()

	// We want to make sure that after waiting, there are some autocomplete
	// suggestions available.
	fmt.Println(len(page.MustElements(".search__autocomplete .acp")) > 0)

}

Output:

true

Variables

View Source 
var DefaultLogger = log.New(os.Stdout, "[rod] ", log.LstdFlags)

DefaultLogger for rod

View Source 
var DefaultSleeper = func() utils.Sleeper {
	return utils.BackoffSleeper(100*time.Millisecond, time.Second, nil)
}

DefaultSleeper generates the default sleeper for retry, it uses backoff to grow the interval. The growth looks like: 

A(0) = 100ms, A(n) = A(n-1) * random[1.9, 2.1), A(n) < 1s

Why the default is not RequestAnimationFrame or DOM change events is because of if a retry never ends it can easily flood the program. But you can always easily config it into what you want.

Functions

func NotFoundSleeper added in v0.88.9 

func NotFoundSleeper() utils.Sleeper

NotFoundSleeper returns ErrElementNotFound on the first call

func Try added in v0.46.0 

func Try(fn func()) (err error)
