Breaking Changes

Downloader changes

The Downloader class was renamed to BrowserFetcher. BrowserFetcher has the following API:

• DefaultRevision
• DownloadsFolder
• DownloadHost
• Platform
• DownloadProgressChanged
• CanDownloadAsync(int revision)
• LocalRevisions()
• Remove(int revision)
• RevisionInfo(int revision)
• DownloadAsync(int revision)
• GetExecutablePath(int revision)
• GetExecutablePath(Platform platform, string folderPath)

If you were using Downloader like this:

await Downloader.CreateDefault().DownloadRevisionAsync(chromiumRevision);

It should be changed to :

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

Puppeteer.LaunchAsync breaking change

In order to simplify the API, the revision argument was removed from the LaunchAsync method. So this piece of code:

Puppeteer.LaunchAsync(launcherOptions, Downloader.DefaultRevision);

Should be changed to:

Puppeteer.LaunchAsync(launcherOptions);

If you need to launch Puppeteer using another revision you should handle that using the ExecutablePath option:

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

v0.7 Page Improvements

We are shipping Puppeteer Sharp v0.7 with many cool new features: Element selectors and evaluation over elements. But our big challenge on v0.7 was one of the hard things in computer science: Naming Things.

Puppeteer has these 5 cool functions:

• $(selector): It calls document.querySelector and returns an ElementHandle.
• $$(selector): It calls document.querySelectorAll and returns an ElementHandle array.
• $eval(selector, function): It calls document.querySelector and executes a function passing the element as an argument.
• $$eval(selector, function): It calls document.querySelectorAll and executes a function passing the element array as an argument.
• $x(xpathExpression): It calls document.evaluate and returns an ElementHandle array.

What do all these methods have in common? Hint: You can solve this using a string.Substring().
Yes, you guessed it right! They all have that $ symbol. And guess what? exactly, we can't name a method $ in C#.

So, in order to give these functions a clear and "csharpy" name, we decided to call them in this way:

• page.$(selector) => page.QuerySelectorAsync(selector)
• page.$$(selector) => page.QuerySelectorAllAsync(selector)
• page.$eval(selector, function) => page.QuerySelectorAsync(selector).EvaluateFunctionAsync(function)
• page.$$eval(selector, function) => page.QuerySelectorAllHandleAsync(selector).EvaluateFunctionAsync(function)
• page.$(selector) => page.XPathAsync(selector)

These methods may be more verbose, but this naming convention makes them clearer and hopefully, easier to learn.

This is the complete list of new APIs we implemented in this version:
- Page.XPathAsync
- Page.QuerySelectorAsync
- Page.QuerySelectorAllAsync
- Page.QuerySelectorAllHandleAsync
- Page.SelectAsync
- Page.ExposeFunctionAsync
- Page.EvaluateOnNewDocumentAsync
- Page.AddScriptTagAsync
- Page.AddStyleTagAsync
- Page.PageError
- JSHandle.EvaluateFunctionAsync
- ElementHandle.EvaluateFunctionAsync
