docx

What is docx?

The docx npm package is a powerful library for creating and manipulating Microsoft Word documents programmatically. It allows developers to generate .docx files with various elements such as text, images, tables, and more, directly from their JavaScript or TypeScript code.

What are docx's main functionalities?

Creating a Simple Document

This feature allows you to create a simple Word document with text. The code sample demonstrates how to create a document with a single paragraph containing both regular and formatted text.

const { Document, Packer, Paragraph, TextRun } = require('docx');
const fs = require('fs');

const doc = new Document({
  sections: [
    {
      properties: {},
      children: [
        new Paragraph({
          children: [
            new TextRun('Hello World!'),
            new TextRun({
              text: ' This is bold and underlined text.',
              bold: true,
              underline: {} 
            })
          ]
        })
      ]
    }
  ]
});

Packer.toBuffer(doc).then((buffer) => {
  fs.writeFileSync('MyDocument.docx', buffer);
});

Adding Images

This feature allows you to add images to your Word document. The code sample demonstrates how to insert an image with specified dimensions into a document.

const { Document, Packer, Paragraph, ImageRun } = require('docx');
const fs = require('fs');

const doc = new Document({
  sections: [
    {
      properties: {},
      children: [
        new Paragraph({
          children: [
            new ImageRun({
              data: fs.readFileSync('path/to/image.png'),
              transformation: {
                width: 100,
                height: 100
              }
            })
          ]
        })
      ]
    }
  ]
});

Packer.toBuffer(doc).then((buffer) => {
  fs.writeFileSync('DocumentWithImage.docx', buffer);
});

Creating Tables

This feature allows you to create tables within your Word document. The code sample demonstrates how to create a table with two rows and two columns.

const { Document, Packer, Table, TableRow, TableCell, Paragraph } = require('docx');
const fs = require('fs');

const doc = new Document({
  sections: [
    {
      properties: {},
      children: [
        new Table({
          rows: [
            new TableRow({
              children: [
                new TableCell({
                  children: [new Paragraph('Cell 1')] 
                }),
                new TableCell({
                  children: [new Paragraph('Cell 2')] 
                })
              ]
            }),
            new TableRow({
              children: [
                new TableCell({
                  children: [new Paragraph('Cell 3')] 
                }),
                new TableCell({
                  children: [new Paragraph('Cell 4')] 
                })
              ]
            })
          ]
        })
      ]
    }
  ]
});

Packer.toBuffer(doc).then((buffer) => {
  fs.writeFileSync('DocumentWithTable.docx', buffer);
});
