How to use Vue and HTMLDocx to generate downloadable Word documents for web content

In modern web development, users often hope to download web content in the form of Word documents. As a popular JavaScript framework, Vue provides convenient data binding and rendering mechanisms. And HTMLDocx is a powerful library that converts HTML content into downloadable Word documents. This article will introduce how to combine Vue and HTMLDocx to achieve this function.

First, we need to install the Vue and HTMLDocx libraries. Execute the following commands in the command line to install them:

npm install vue htmldocx

Then, introduce and use these two libraries in the Vue component. The following is a sample Vue component:

<template>
  <div>
    <button @click="exportToWord">导出Word</button>
  </div>
</template>

<script>
import htmlDocx from 'htmldocx';
import { saveAs } from 'file-saver';

export default {
  methods: {
    exportToWord() {
      // 获取要导出的HTML内容
      const htmlContent = document.getElementById('myHtml').innerHTML;

      // 创建一个Blob对象，用于保存Word文件
      const blob = htmlDocx.asBlob(htmlContent, {
        orientation: 'portrait', // 文档方向，可选项为portrait和landscape
        margins: { top: 720, right: 720, bottom: 720, left: 720 }, // 页边距，单位为Twips（1 inch = 1440 Twips）
      });

      // 将Blob保存为Word文件并下载
      saveAs(blob, 'myWordDocument.docx');
    },
  },
};
</script>

<style>
...
</style>

In the above code, we first introduced htmldocx and file-saver, and then defined an exportToWordmethod. This method generates a Blob object for the Word document by getting the content of the HTML element with a specific id and passing it to the htmlDocx.asBlob function. Optionally, you can specify the document's orientation and margins. Finally, we use the saveAs function of the file-saver library to save the Blob object as a Word file and set the file name to myWordDocument.docx.

In actual use, you need to place the HTML content to be exported in the Vue template and set a unique id for it. For example:

<template>
  <div>
    <div id="myHtml">
      <!-- 这里是要导出为Word的内容 -->
    </div>
    <button @click="exportToWord">导出Word</button>
  </div>
</template>

Finally, we need to ensure that the Vue component is loaded correctly and the corresponding routing rules are set. Here is only an example of a Vue single-file component. In actual use, you may need to combine routing and other components for setup.

In addition, it should be noted that since HTMLDocx uses browser native API, it may not work properly for older versions of browsers that do not support Blob and FileSaver API. It is recommended that you conduct compatibility testing and provide alternative solutions.

In summary, combining Vue and HTMLDocx, we can easily provide users with downloadable Word document functionality. With just a few lines of code, we are able to convert the HTML content into a Word-formatted Blob object and save it as a Word file using the file-saver library. Additionally, you can set the document's orientation and margins as needed. I hope this article can help you implement this feature in your Vue project.
