API Reference

forgePDF(otps: Options | string):Promise<Buffer | Readable | Uint8Array>

Generates a PDF from a URL or HTML string, providing several customization options for fine-tuning output.

Parameters

• options (Options

  string): If a string is provided, it’s treated as a URL to be visited. Alternatively, an Options object can be passed to specify additional settings.

Returns

• Promise<Buffer | Readable | Uint8Array>
  Returns a Promise that resolves to the generated PDF in the specified format: a Buffer, a Readable stream, or a Uint8Array. The default output would be a Buffer. If stream in options is set to true, Readable stream will be returned. If raw is set to true, the raw Uint8Array from puppeteer is returned.

Options

Option	Type	Description
url	string	The URL to visit for generating the PDF. Required if html is not provided.
html	string	HTML content to render directly on the page, which is faster than loading a URL. Required if url is not provided.
launchOpts	LaunchOptions	Puppeteer’s launch options for customizing the browser instance (headless mode, executable path, etc.).
goToOptions	GoToOptions	Options to configure Puppeteer’s page.goto() method, like navigation timeout or waitUntil conditions.
waitForSelector	string	CSS selector for an element that must be visible before the PDF generation begins.
waitForSelectorOpts	WaitForSelectorOptions	Options for waiting on the selector, such as visibility conditions and timeout.
pdfOpts	PDFOptions	Puppeteer’s PDF options, like page format, margins, and print background settings.
saveToFile	boolean	If true, saves the PDF to a file instead of returning it as a Buffer. Specify the file path in pdfOpts.
raw	boolean	When true, returns the PDF in Uint8Array format for direct binary manipulation.
stream	boolean	If true, returns the PDF as a readable stream instead of a Buffer.
disableJavascript	boolean	If true, disables JavaScript execution on the page, useful for static content.
cookies	CookieParam[]	List of cookies to inject into the page for authentication or session management.
