Question 1

How to add custom fonts to PDF on Android using react-native-html-to-pdf?

Accepted Answer

Use the 'fonts' option in the configuration array with file paths like '/fonts/TimesNewRoman.ttf'. Ensure the font files are correctly included in your Android assets directory for proper rendering.

Question 2

Does react-native-html-to-pdf support CSS3 styles in HTML?

Accepted Answer

It converts HTML strings to PDF, so basic CSS should work, but complex CSS3 features might not render consistently due to platform-specific WebView limitations. Testing with your specific styles is essential.

Question 3

react-native-html-to-pdf vs react-native-pdf-lib: which is better?

Accepted Answer

react-native-html-to-pdf is better for simple HTML-to-PDF conversion with easy setup, while react-native-pdf-lib offers more advanced PDF manipulation like editing existing PDFs but requires more native integration effort.

Question 4

How to handle errors when generating PDFs with this library?

Accepted Answer

Wrap the generatePDF call in a try-catch block since it's promise-based. Common errors include invalid HTML or file permission issues; check console logs for specific error messages from the native layer.

Question 5

Can I generate PDFs in the background on iOS with react-native-html-to-pdf?

Accepted Answer

The library doesn't explicitly support background generation; it runs on the main thread, so for background tasks, you might need to implement native workarounds or consider server-side alternatives.

Question 6

What are common pitfalls when using custom HTML for PDF generation?

Accepted Answer

Complex layouts or large images can cause performance issues or rendering artifacts. Keep HTML simple, avoid excessive CSS, and test on both iOS and Android to ensure consistent output.
