svg2pdf.js: "path" dont works on angular build --prod

[Solangetatiana]

"path" dont works on angular build --prod or even when file angular.json has the options below set to build in dev (the same when build --prod ):

            "aot": true,
            "optimization": true,

Steps to reproduce the behavior: Foloow the github link: https://github.com/Solangetatiana/example-path-svg2pdf

1. 1 The SVG sample has rect, line, path and circle:

   
   <svg id="area_svg_print" xmlns="http://www.w3.org/2000/svg"
    width="400"
    height="400"
    viewBox="4.5 1.5 51 49"
    baseProfile="full" version="1.1" >
   <g id=desenho_total_print>
     <line x1="10" y1="7" x2="20" y2="17" style="stroke: green; fill: none; stroke-width: 0.1;" stroke-dasharray="0.5,0.5"></line>
     <rect x="5" y="5" width="10" height="10" style="stroke: green; fill: none; stroke-width: 0.1;"></rect>
     <path d="M 10 12 Q 15 7 20 12 " style="stroke: green; fill: none; stroke-width: 0.1;" stroke-dasharray="0.5,0.5"></path>
     <circle cx="10" cy="10" r="5" style="stroke: blue; fill: none; stroke-width: 0.1;" stroke-dasharray="0.5,0.5" />
   </g>
   </svg>

2.2

async createPDF() { const areaSvg = document.getElementById('area_svg_print'); const desenhoTotal = document.getElementById('desenho_total_print');

const pdf = new jsPDF('portrait', 'cm', [21.0, 29.6]);

await pdf.svg(areaSvg, { width: 21.0, height: 29.6 });
const uri = pdf.output('datauristring');
this.download(uri);

}

download(uri) { const link = document.createElement('a'); link.download = 'exemple.PDF'; link.href = uri; link.click(); }

2. I The result is: rect, line and circle were generated on the PDF, except path.

**Sample with the error **(npm start when the file angular.json with "aot": true and "optimization": true)**
ATTENTION: The same result as an angular build --prod**

**Sample without error **(npm start when the file angular.json with "aot": false and without option "optimization": true)****

Thanks for your report! Angular is known to break software that wasn't written by the angular team itself ;-) Specifically their "optimizer" prefers smaller over working code. Which exact version of angular and the build optimizer are you using? And did you already try to debug the issue?

[yGuy]

Ah - this is about this set of versions - isn't it? So did you already try debugging it yourself?

[Solangetatiana]

Yes!! The package.json has the versions! Angular 8.

I don't have a clear idea of how to debug and how to get around this before generating the build with minified code ...

[yGuy]

Did you try with a more recent version of angular (newest version 9, or even 10?) I remember there were many issues in version 8. If you're looking to crash your software, use angular 8 "production" builds ;-)
