怎么利用node生成word文档？下面本篇文章给大家介绍一下使用node生成word文档的方法，分享一个实用库，聊聊该库的使用方法，希望对大家有所帮助！
最近有项目需要用到生成word文档，平时经常用的都是通过模板生成，里面变量使用占位符替换，好处是快捷、方便、简单、不需要通过代码调word样式，确定是很多库不支持图片绘制（很多都是付费功能），找一圈，发现一个很有意思的库，正好也满足我们的需求，特此分享一下
依赖// https://docx.js.org/#/npm i docx // https://www.npmjs.com/package/downloadnpm i download登录后复制
说明，因为docx绘图只支持文件流，所以要把网络文件下载到本地转成buffer
代码话不多说，上代码
