[Question]: Is playwhright-go thread-safe if multiple instances are created in separate go routines?

[martingrzzler]

I'm using this awesome library for web scraping but when running browsers in parallel I get random crashes. So this might be because the library is not thread-safe. In the following example I create two different instances of Chrome with playwhright.Run. Is this save to do?

package main

import (
	"sync"

	"github.com/crawler/internal/crawl"
)

func main() {

	wg := sync.WaitGroup{}

	wg.Add(1)
	go func() {
		defer wg.Done()
                // creates a new instances with playwhright.Run
		b1, err := crawl.LauchBrowser(crawl.LaunchOptions{
			Headless: false,
		})
		if err != nil {
			panic("failed to launch browser" + err.Error())
		}
		for i := 0; i < 10; i++ {
			p, err := crawl.NewPage(b1)
			if err != nil {
				panic("failed to create new page" + err.Error())
			}

			_, err = crawl.ScrapeHomePage(p, "https://google.com")
			if err != nil {
				panic("failed to scrape home page" + err.Error())
			}

			err = p.Context().Close()
			if err != nil {
				panic("failed to close context" + err.Error())
			}
		}

	}()

	wg.Add(1)
	go func() {
		b2, err := crawl.LauchBrowser(crawl.LaunchOptions{
			Headless: false,
		})
		if err != nil {
			panic("failed to launch browser" + err.Error())
		}
		defer wg.Done()

		for i := 0; i < 10; i++ {
			p, err := crawl.NewPage(b2)
			if err != nil {
				panic("failed to create new page" + err.Error())
			}

			_, err = crawl.ScrapeHomePage(p, "https://example.com")
			if err != nil {
				panic("failed to scrape home page" + err.Error())
			}

			err = p.Context().Close()
			if err != nil {
				panic("failed to close context" + err.Error())
			}

		}
	}()

	wg.Wait()
}
