问题描述

我正在尝试使用pdfmake在ionic2中创建pdf。

I'm trying to create pdf in ionic2 with pdfmake.

我将库添加到我的应用中：

I added the library to my app:

$ npm install pdfmake --save

导入它进入班级

import { Component } from '@angular/core';
import { NavController, NavParams, LoadingController, ToastController, AlertController } from 'ionic-angular';

import * as pdfmake from 'pdfmake'

但是，当我尝试实例化并使用该方法，显示设备中的错误：

But, When I try to instantiate and use the method, the displayed error in the device:

var dd = {
    content: [
        'First paragraph',
        'Another paragraph, this time a little bit longer to make sure, this line will be divided into at least two lines'
    ],
    pageSize: 'A4',
    pageMargins: [25, 25, 25, 25],
};

// download the PDF
var pdf = new pdfmake();
pdf.createPdf( dd ).download();

运行时错误：

fs.readFileSync is not a function

推荐答案

所以......再次......经过很多天，我终于通过pdfmake社区的帮助获得pdfmake来处理我的项目。

So... again... After many days, I finally get the pdfmake to work on my project with pdfmake community's help .

我克隆了编译版本进入www文件夹

I cloned the compiled version into the www folder

$ cd  project/www/
$ git clone https://github.com/bpampuch/pdfmake.git

然后我将脚本添加到索引中。

Then I added the scripts to the index.

<body>

  <!-- Ionic's root component and where the app will load -->
  <ion-app></ion-app>

  <!-- The polyfills js is generated during the build process -->
  <script src="build/polyfills.js"></script>

  <!-- The bundle js is generated during the build process -->
  <script src="build/main.js"></script>
  <script src='pdfmake/build/pdfmake.min.js'></script>
  <script src='pdfmake/build/vfs_fonts.js'></script>
</body>
</html>

并将导入替换为...

and replace import to ...

import * as pdfmake from 'pdfmake/build/pdfmake';
