Puppeteer Sharp is a .NET port of the official Node.JS Puppeteer API.
PuppeteerSharp now supports AOT compilation! Check the PuppeteerSharp 19 release notes!.
Some of the best ways to contribute are to try things out file bugs and fix issues.
If you have an issue or a question:
See this document for information on how to contribute.
var browserFetcher = new BrowserFetcher();
await browserFetcher.DownloadAsync();
await using var browser = await Puppeteer.LaunchAsync(
new LaunchOptions { Headless = true });
await using var page = await browser.NewPageAsync();
await page.GoToAsync("http://www.google.com");
await page.ScreenshotAsync(outputFile);
You can also change the view port before generating the screenshot
await Page.SetViewportAsync(new ViewPortOptions
{
Width = 500,
Height = 500
});
var browserFetcher = new BrowserFetcher();
await browserFetcher.DownloadAsync();
await using var browser = await Puppeteer.LaunchAsync(new LaunchOptions { Headless = true });
await using var page = await browser.NewPageAsync();
await page.GoToAsync("http://www.google.com"); // In case of fonts being loaded from a CDN, use WaitUntilNavigation.Networkidle0 as a second param.
await page.EvaluateExpressionHandleAsync("document.fonts.ready"); // Wait for fonts to be loaded. Omitting this might result in no text rendered in pdf.
await page.PdfAsync(outputFile);
await using var page = await browser.NewPageAsync();
await page.SetContentAsync("<div>My Receipt</div>");
var result = await page.GetContentAsync();
await using var page = await browser.NewPageAsync();
var seven = await page.EvaluateExpressionAsync<int>("4 + 3");
var someObject = await page.EvaluateFunctionAsync<JsonElement>("(value) => ({a: value})", 5);
Console.WriteLine(someObject.GetProperty("a").GetString());
using (var page = await browser.NewPageAsync())
{
await page.GoToAsync("http://www.spapage.com");
await page.WaitForSelectorAsync("div.main-content")
await page.PdfAsync(outputFile));
}
using (var page = await browser.NewPageAsync())
{
await page.GoToAsync("http://www.spapage.com");
var watchDog = page.WaitForFunctionAsync("()=> window.innerWidth < 100");
await page.SetViewportAsync(new ViewPortOptions { Width = 50, Height = 50 });
await watchDog;
}
var options = new ConnectOptions()
{
BrowserWSEndpoint = $"wss://www.externalbrowser.io?token={apikey}"
};
var url = "https://www.google.com/";
using (var browser = await PuppeteerSharp.Puppeteer.ConnectAsync(options))
{
using (var page = await browser.NewPageAsync())
{
await page.GoToAsync(url);
await page.PdfAsync("wot.pdf");
}
}
