Using vue js as html preprocessor?

Question

SVG

Hello, when creating a triangle in svg, I need to specify polygon points. Since the triangle is regular and svg is square, this is a triangle inscribed in svg. Assuming that the desired side of the triangle is 100, we find the side of the square - 200. And since the triangle does not fit perfectly into the square, the side of the square used is 50*sqrt(3). I need to be able to get the compiler to accurately calculate the expression 50*sqrt(3). Like scss. How can I do this. I need the expression to be read only by the compiler (because I'm using the vue 2 cli webpack builder) and not by the user's PC....
