Getting Started with ChromeDP

This article will walk you through the process of leveraging BrowserCat and ChromeDP for browser automation at scale.

Prerequisites

Before you get started, you’ll need to:

1. Sign up for a free BrowserCat account.
2. Create an API key.
3. Install ChromeDP in your project…

go get -u github.com/chromedp/chromedp

Your first automation

The following script connects to a BrowserCat browser, navigate to a website, and print the page title.

With a little tweaking (and the chromedp docs), you can automate literally anything you can do in a real browser.

package main

import (
	"context"
	"log"

	"github.com/chromedp/chromedp"
)

func main() {
	bcatUrl := "wss://api.browsercat.com/connect?apiKey=<YOUR_API_KEY>"

	allocatorContext, cancel := chromedp.NewRemoteAllocator(
		context.Background(),
		bcatUrl,
		chromedp.NoModifyURL,
	)
	defer cancel()

	ctx, cancel := chromedp.NewContext(allocatorContext)
	defer cancel()

	var title string
	if err := chromedp.Run(ctx,
		chromedp.Navigate("https://example.com"),
		chromedp.Title(&title),
	); err != nil {
		log.Fatalf("Failed getting title of example.com: %v", err)
	}

	log.Println(title)
}

Configure the browser

It’s really easy to configure our browsers for your needs. Whether you want to connect to a specific region, set up a third-party proxy, or customize your browser launch args, we’ve got you covered.

See out browser config docs for more info.
