Custom PDF Building Blocks

The core of our simplified PDF creation process lies in a set of custom components that mirror common layout structures in web development. These include:

  • PDFVStack & PDFVStackFull: Vertical stacks for organizing content
  • PDFHStack & PDFHStackFull: Horizontal stacks for side-by-side layouts
  • PDFFlex & PDFFlexFull: Flex containers for responsive layouts
  • PDFCenter: A component for centering content
  • PDFDivider: A simple divider line for visual separation

The PDFContainer Component

  • Font Registration: We register custom fonts to ensure consistent typography across the PDF.
  • Font.register({ family: "Roboto", src: "/fonts/Roboto-Regular.ttf" });
  • Page Styling: We define a default style for our PDF pages.
  • const styles = StyleSheet.create({ 
      page: { 
        flexDirection: "column", 
        backgroundColor: "#fae4b4", 
        fontFamily: "Roboto", 
        padding: "0.7in" 
        } });
  • PDF Generation and Download: The component includes a function to generate and download the PDF.
  • const downloadPDF = async () => { const doc = 
      ( <Document 
        author="Dark Violet AI" 
        creator="Dark Violet AI">
          <Page size="LETTER" style={styles.page}>
            <PDFInnerContainer>{children}</PDFInnerContainer>
          </Page></Document> ); 
        const asBlob = await pdf(doc).toBlob(); 
        fileSaver.saveAs(asBlob, fileName); };
  • Download Button: The component renders a button that triggers the PDF download when clicked.
