Is it possible to draw lines
, circles
and other shapes
with pdfmake? If yes, is there a documentation
or are there any samples? I would like to replace jsPDF with pdfmake.

Yes, its possible. pdfmake calls them vectors. See pdfMake Vector examples for more possibilities.
An example for drawing a line followed by a polygon:
{
canvas:
[
{
type: 'line',
x1: 40, y1: 60,
x2: 260, y2: 60,
lineWidth: 3
},
{
type: 'polyline',
lineWidth: 3,
closePath: true,
points: [{ x: 10, y: 10}, { x: 35, y: 40 }, { x: 100, y: 40 }, { x: 125, y:10 }]
}
]
}

I answered an issue in pdfMake at GitHub like this:
Create a table with layout headeronly you must define an empty body, otherwise the line would not appear:
var dd = {
content: [
{
table : {
headerRows : 1,
widths: [200],
body : [
[''],
['']
]
},
layout : 'headerLineOnly'
}
] }
The width defines the length of the line

2The nice thing about this method is that you can specify widths as a percentage, like '100%' or '50%'. I didn't see that you can do that with canvas. – eflat Oct 03 '19 at 18:59

The line is bit too thick, how to control it's thickness? – gegobyte Jan 14 '21 at 12:03

canvas: [
{
type: 'rect',
x: 198,
y: -186,
w: 198,
h: 188,
r: 8,
lineWidth: 4,
lineColor: '#276fb8',
},
]

As far as I know, pdfmake does not provide an drawing API. Despite this, pdfmake provides you some methods to insert images at your pdf.
Best regards!
