Vue PDF Generation with pdfmake Wrapper: A Comprehensive Guide

As a Fullstack Developer, working with PDFs has become an essential part of our daily tasks. From generating invoices and receipts to creating reports and certificates, PDFs play a crucial role in various industries. In this article, we will explore the process of generating PDFs in Vue.js using the pdfmake wrapper.

Why pdfmake Wrapper?

Before diving into the world of PDF generation, let's discuss why we choose to use the pdfmake wrapper over other libraries and frameworks. The main reasons are:

• Flexibility: pdfmake wrapper provides an intuitive API that allows us to generate complex layouts and designs with ease.
• Customization: With its powerful template engine, we can customize every aspect of our PDFs, from fonts and colors to margins and padding.
• Speed: pdfmake wrapper is optimized for performance, ensuring that our PDFs are generated quickly and efficiently.

Setting Up Vue.js and pdfmake Wrapper

To get started with generating PDFs in Vue.js using the pdfmake wrapper, we need to install two packages: vue-pdfmake and pdfmake. We can do this by running the following commands:

npm install vue-pdfmake pdfmake

Next, let's create a new Vue.js project and set up our environment. For the sake of simplicity, we will use the official Vue CLI to create a new project.

Generating PDFs in Vue.js

Now that we have set up our environment, let's dive into generating our first PDF. We can do this by creating a new component in our Vue.js project and importing the vue-pdfmake package.

// src/components/PdfGenerator.vue

<template>
  <div>
    <button @click="generatePdf">Generate PDF</button>
  </div>
</template>

<script>
import pdfMake from 'pdfmake';

export default {
  methods: {
    generatePdf() {
      const docDefinition = {
        content: [
          {
            text: 'Hello, World!',
            style: 'header'
          },
          {
            text: 'This is a paragraph of text.',
            style: 'paragraph'
          }
        ],
        styles: {
          header: {
            fontSize: 18,
            bold: true
          },
          paragraph: {
            fontSize: 14,
            alignment: 'justify'
          }
        }
      };

      const pdfDoc = pdfMake.createPdf(docDefinition);
      pdfDoc.open();
    }
  }
};
</script>

In the above code, we have created a simple button that generates a PDF when clicked. The generatePdf method creates a new pdfDoc object using the pdfmake.createPdf() function and then opens it.

Working with Tables

One of the most useful features of pdfmake wrapper is its ability to generate complex tables with ease. Let's modify our previous code to include a table:

// src/components/PdfGenerator.vue

<template>
  <div>
    <button @click="generatePdf">Generate PDF</button>
  </div>
</template>

<script>
import pdfMake from 'pdfmake';

export default {
  methods: {
    generatePdf() {
      const docDefinition = {
        content: [
          {
            text: 'Hello, World!',
            style: 'header'
          },
          {
            table: {
              headerRows: 1,
              widths: ['*', '*'],
              body: [
                ['Column 1', 'Column 2'],
                ['Cell 1, Row 1', 'Cell 2, Row 1'],
                ['Cell 3, Row 1', 'Cell 4, Row 1']
              ]
            }
          },
          {
            text: 'This is a paragraph of text.',
            style: 'paragraph'
          }
        ],
        styles: {
          header: {
            fontSize: 18,
            bold: true
          },
          paragraph: {
            fontSize: 14,
            alignment: 'justify'
          }
        }
      };

      const pdfDoc = pdfMake.createPdf(docDefinition);
      pdfDoc.open();
    }
  }
};
</script>

In the above code, we have added a table to our PDF. We can customize every aspect of this table, from its layout and design to its font and colors.
