Trying to use client-side pdf library pdfmake in my Angular 2 (version=4.2.x) project.
In .angular-cli.json file, I declared js like this:
"scripts": [
"../node_modules/pdfmake/build/pdfmake.js",
"../node_modules/pdfmake/build/vfs_fonts.js"
]
And then in app.component.ts, I used it like this:
import * as pdfMake from 'pdfmake';
@Component({
selector: 'app-root',
templateUrl: './app.component.html',
styleUrls: ['./app.component.scss']
})
export class AppComponent implements OnInit {
pdf: any;
downloadPdf() {
let item = {firstName: 'Peter', lastName: 'Parker'};
this.pdf = pdfMake;
this.pdf.createPdf(buildPdf(item)).open();
}
}
function buildPdf(value) {
var pdfContent = value;
var docDefinition = {
content: [{
text: 'My name is: ' + pdfContent.firstName + ' ' + pdfContent.lastName + '.'
}]
}
console.log(pdfContent);
return docDefinition;
}
I hit below error in browser console when loading the app:
Uncaught TypeError: fs.readFileSync is not a function

My workaround for solving this problem is:
Copy pdfmake.js and vfs_fonts.js to assets folder, and then add this to index.html:
<script src='assets/pdfmake.min.js'></script>
<script src='assets/vfs_fonts.js'></script>
Remove this from app.component.ts
import * as pdfMake from 'pdfmake';
And add this to app.component.ts:
declare var pdfMake: any;
Finally remove this from .angular-cli.js:
"../node_modules/pdfmake/build/pdfmake.js",
"../node_modules/pdfmake/build/vfs_fonts.js"
It works but it's still a workaround.
Anyone knows how to use this library in Angular/Typscript way?
Thanks a lot!
Following the instruction above made by @benny_boe , I've made it work! Let me summarize it as below:
First,
npm install pdfmake --save
Second, add below to typings.d.ts:
declare module 'pdfmake/build/pdfmake.js';
declare module 'pdfmake/build/vfs_fonts.js';
Third, in the file where pdfMake is being used, either component or service, add below lines:
import * as pdfMake from 'pdfmake/build/pdfmake.js';
import * as pdfFonts from 'pdfmake/build/vfs_fonts.js';
pdfMake.vfs = pdfFonts.pdfMake.vfs;
Last, use pdfMake.xxx() as usual.
