javascript - jsPDF 服务器端 (node.js) 使用 node-jspdf

Question

我实际上是在尝试在服务器端包含 jspdf，然后将其用于简单的 pdf 生成(只是文本“Hello world!”)(转到 url - 获取 pdf localhost:8080)。现在我面临的第一个问题是

• 如何包含它/如何在 Node 中使用 jsPDF？
• 尝试使用 npm install node-jspdf 安装它时出现以下错误-

> G:\test\myproj>npm install node-jspdf
 node-jspdf@0.0.3 install G:\test\myproj\node_modules\node-jspdf
 sh install.sh

任何人都可以帮助我如何将它包含在 Node 中吗？并给出一个4-5行的demo。

您实际上可以直接使用 jspdf(npm install jspdf 而不是 npm install node-jspdf)。 Jspdf 当前 (v1.3.2) 构建时并未考虑 Node 支持，但您可以像下面这样模拟全局变量并使其以这种方式工作。这是一个基本示例，jspdf 的所有功能将不可用。

global.window = {document: {createElementNS: () => {return {}} }};
global.navigator = {};
global.html2pdf = {};
global.btoa = () => {};

var fs = require('fs');
var jsPDF = require('jspdf');

var doc = new jsPDF();
doc.text("Hello", 10, 10);
var data = doc.output();

fs.writeFileSync('./document.pdf', data, 'binary');

delete global.window;
delete global.html2pdf;
delete global.navigator;
delete global.btoa;
