Support for Azure

Description

Trying hole day. Is it possible to run on Azure App Service? Also when trying to copy installation result from npm install puppeteer to output I still get the error Win32Exception: The application has failed to start because its side-by-side configuration is incorrect. Please see the application event log or use the command-line sxstrace.exe tool for more detail at this line PuppeteerSharp.Launcher.LaunchAsync(LaunchOptions options) And I simply can’t install chrome there.

Hope you can help or be able how to get this cool project running on azure.

thank you

Complete minimal example reproducing the issue

      public class HomeController : Controller
{
    string path;
    public HomeController(IHostingEnvironment hostingEnvironment) {
        this.path = hostingEnvironment.ContentRootPath;
    }
    public async Task<IActionResult> Index()
    {
        bool exist = false;
        using(var browser = await PuppeteerSharp.Puppeteer.LaunchAsync(new LaunchOptions() {
            Headless = true,
            ExecutablePath = this.path + @"\node_modules\puppeteer\.local-chromium\win64-564778\chrome-win32\chrome.exe"
        })) {
            using(var page =await browser.NewPageAsync()) {
                var response = await page.GoToAsync("http://www.sales-suckers.com");
                var res = await page.EvaluateExpressionAsync<dynamic>("window.salessuckers");
                exist = res != null;
            }
        }
        ViewData.Add("EXIST", exist);
        return View();
    }

}

Expected behavior:

Please add description how to run within Azure App Service or add support to it.

You can now use Puppeteer on Azure Functions running on Linux: https://anthonychu.ca/post/azure-functions-headless-chromium-puppeteer-playwright/

Consumption plan only at time of writing. The article talks about Node.js but I’ve tested the code below and it works fine.

public static async Task<IActionResult> Run(
    [HttpTrigger(AuthorizationLevel.Anonymous, "get", "post", Route = null)] HttpRequest req,
    ILogger log)
{
    string url = req.Query["url"];
    url = url ?? "https://google.com";

    var downloadsFolder = Path.GetTempPath(); // Need to use a folder with write permissions. "/tmp/" in Azure 
    log.LogInformation($"downloadsFolder: {downloadsFolder}");

    var browserFetcher = new BrowserFetcher(new BrowserFetcherOptions
    {
        Path = downloadsFolder
    });

    await browserFetcher.DownloadAsync(BrowserFetcher.DefaultRevision);
    var browser = await Puppeteer.LaunchAsync(new LaunchOptions
    {
        Headless = true,
        ExecutablePath = browserFetcher.RevisionInfo(BrowserFetcher.DefaultRevision).ExecutablePath
    });

    var page = await browser.NewPageAsync();
    await page.GoToAsync(url);
    var screenshotStream = await page.ScreenshotStreamAsync(new ScreenshotOptions { Type = ScreenshotType.Png, FullPage = true });

    return new FileStreamResult(screenshotStream, "image/png");
}

I tried to run it in an azure web app and it fails. This is my code

              var options = new LaunchOptions
                {
                    Headless = true
                };

                await new BrowserFetcher().DownloadAsync(BrowserFetcher.DefaultRevision);

                
                using (var browser = await Puppeteer.LaunchAsync(options))
                using (var page = await browser.NewPageAsync())
                {
                    await page.GoToAsync(htmlurl);
                    document = await page.PdfStreamAsync();
                }

                return document;

It fails on this line using (var browser = await Puppeteer.LaunchAsync(options)) and I don’t even get an exception. The call fails with a 502 invalid gateway error. I was hopeful of using this to generate pdf’s 😃
