Multiline footer with PDFMake - node.js

Question

I am trying to create a multiline footer with pdfmake; what I was able to do until now:
const docDefinition = {
footer: [
{
stack: [
{ text: "Line 1" },
{ text: "Line 2" },
{ text: "Line 3" },
{ text: "Line 4" }
], style: 'footer'
}
],
styles: {
footer: {
fontSize: 6, bold: true, alignment: 'center'
}
}
};
While this creates what I want, the style is not correct. As soon as I increase the font size, the bottom line starts to disappear. If I set the font size to 12, only the first two lines appear in the generated PDF on the server-side.
What change do I need to make here?

Answer 1

You just need to add margin to the page and you can accommodate as many lines as you want. e.g. Enter the code below in pdfmake playground: http://pdfmake.org/playground.html
// playground requires you to assign document definition to a variable called dd
let textFooter = `

This is line 2 - 263139\n
Line 3 comes here\n

var dd = {
header: function(currentPage, pageCount, pageSize) {
return [
{ text: 'simple text\naaa\nbbb\nccc\nddd', alignment: 'center', fontSize: 9 },
]
},
footer: function(currentPage, pageCount, pageSize) {
return [
{ text: textFooter, alignment: 'center', fontSize: 9 },
]
},
// margin: [left, top, right, bottom]
pageMargins: [ 40, 60, 40, 100 ],
content: [
'First paragraph',
'Another paragraph, this time a little bit longer to make sure, this line will be divided into at least two lines'
]
}
In the code above, I have set margin bottom to 100 which gives us space to include 4 lines.
