Overview

Record Books uses react-pdf to generate PDF reports. The reports are generated based on the data stored in the application and are used to provide a printable version of the data. The report components define templates for the reports the application supports. The reports can be found in the src/app/components/reports directory. In the following sections, we will discuss the various reports used in the Record Books application.

Introduction to React PDF

React PDF is a library that allows you to generate PDF documents using React components. The library provides a set of components that can be used to define the structure of the PDF document. The components provided by React PDF are similar to the HTML elements, and they can be used to define the layout of the PDF document.

In this section, we will go over basic concepts of React PDF and how it is used in the Record Books application. For more information on React PDF, you can refer to the official documentation.

Creating PDF Reports

The Record Books project uses React PDF to generate PDF reports for users. The PDF reports are generated using the @react-pdf/renderer package, which is a renderer for React PDF that allows you to render PDF documents on the client-side.

The basic structure of a PDF report in the Record Books application consists of a Document component that contains a Page component. The Page component contains the content of the report, which is defined using other React PDF components.

The following is an example of a simple PDF:

import { Document, Page, Text, View } from '@react-pdf/renderer';

const MyDocument = () => (
  <Document>
    <Page>
      <View>
        <Text>Hello, World!</Text>
      </View>
    </Page>
  </Document>
);

In the example above, we define a simple PDF document that contains a single page with a text element that says "Hello, World!". The Document component is the root component of the PDF document, and it contains one or more Page components. The Page component defines the content of the page, which can contain other React PDF components.

Styling PDF Reports

React PDF provides a set of components that can be used to style the PDF reports. The components provided by React PDF are similar to the HTML elements, and they can be styled using the style prop.

The following is an example of styling a PDF report:

import { Document, Page, Text, View, StyleSheet } from '@react-pdf/renderer';

const styles = StyleSheet.create({
  page: {
    flexDirection: 'row',
    backgroundColor: '#E4E4E4',
  },
  section: {
    margin: 10,
    padding: 10,
    flexGrow: 1,
  },
});

const MyDocument = () => (
  <Document>
    <Page style={styles.page}>
      <View style={styles.section}>
        <Text>Section #1</Text>
      </View>
      <View style={styles.section}>
        <Text>Section #2</Text>
      </View>
    </Page>
  </Document>
);

In the example above, we define a PDF document with two sections, each containing a text element. We use the StyleSheet.create method to define the styles for the PDF document. The styles are then applied to the components using the style prop.

Using components in PDF Reports

PDFs can also use components to render data.

import { Document, Page, Text, View, StyleSheet } from '@react-pdf/renderer';

const styles = StyleSheet.create({
  page: {
    flexDirection: 'row',
    backgroundColor: '#E4E4E4',
  },
  section: {
    margin: 10,
    padding: 10,
    flexGrow: 1,
  },
});

const Page1 = () => (
    <View style={styles.section}>
        <Text>Section #1</Text>
    </View>
);

const Page2 = () => (
    <Page style={styles.page}>
        <View style={styles.section}>
            <Text>Section #2</Text>
        </View>
    </Page>
);

const MyDocument = () => (
  <Document>
    <Page style={styles.page}>
        <View style={styles.section}>
            <Text>Section #1</Text>
        </View>
    </Page>
    <Page2 />
  </Document>
);

In the example above, we define a PDF document with two sections, each containing a text element. We use the StyleSheet.create method to define the styles for the PDF document. The styles are then applied to the components using the style prop. We also define two components Page1 and Page2 that contain the content of the PDF document. The components are then used in the MyDocument component to render the PDF document.
