Angular.JS to PDF

IronPDF for Python can render JavaScript-driven web applications — including Angular sites — to PDF by enabling JavaScript execution and waiting for the framework to complete its initial render.

Getting Started

Set RenderingOptions.EnableJavaScript = True and configure a render delay using WaitFor.RenderDelay(ms) to give Angular (or any other JavaScript framework) time to bootstrap and render its components before the PDF is captured. Then call RenderUrlAsPdf with the target URL.

Understanding the Code

EnableJavaScript: Enables JavaScript execution during rendering. This is required for any single-page application (SPA) framework such as Angular, React, or Vue.
WaitFor.RenderDelay(500): Pauses for 500 milliseconds after the page has loaded. Angular and similar frameworks need this time to compile templates and populate the DOM. Increase this value if the rendered PDF still shows loading states.
RenderUrlAsPdf(url): Fetches the URL, executes JavaScript, waits for the delay, then captures the fully rendered page as a PDF.

Tuning the Render Delay

The ideal delay depends on the complexity of the page and the speed of the server. For simple components, 200–500 ms is usually sufficient. For pages with multiple async data fetches, consider using WaitFor conditions based on specific DOM elements appearing rather than a fixed time delay.
