A declaritive SVG path builder

$ npm i svg-path-js

import Builder from 'svg-path-js';

function renderSvgPath() {
  const builder = new Builder();
  const path = builder
                .moveTo(10, 10)
                .lineToRel(10, 10)
                .cubicToRel(20, 20, 40, 20, 50, 10)
                .smoothToRel(150, 150, 180, 80)
                .arcTo(30, 50, 0, false, true, 165.55, 162.45)
                .close();
        
  return <Path d={path}/>
  // => 'M 10 10 l 10 10 c 70 20, 120 20, 120 10 s 150 150, 180 80 A 30 50 0 0 1 165.55 162.45 z'

• moveTo(x: number, y: number) move to position without drawing a line absolute
• moveToRel(x: number, y: number) move to position without drawing a line relative
• lineTo(x: number, y: number) draw a line from current position to point absolute
• lineToRel(x: number, y: number) draw a line from current position to point relative
• horizontalTo(x: number) draw line from current position to point absolute
• horizontalToRel(x: number) draw line from current position to point relative
• verticalTo(y: number) draw a line from current position to point absolute
• verticalToRel(y: number) draw a line from current position to point relative
• cubicTo(x1: number, y1: number, x2: number, y2: number, x: number, y: number) draw a cubic bezier curve from current position to point absolute
• cubicToRel(y) draw a cubic bezier curve from current position to point relative
• smoothTo(x2: number, y2: number, x: number, y: number) draw a smooth curve from previous curve to point absolute
• smoothToRel(x2: number, y2: number, x: number, y: number) draw a smooth curve from previous curve to point relative
• quadTo(x1: number, y1: number, x: number, y: number) draw a quadradic curve from current position to point absolute
• quadToRel(x1: number, y1: number, x: number, y: number) draw a quadradic curve from current position to point relative
• quadStringTo(x: number, y: number) draw a quadradic curve from previous curve to point absolute
• quadStringToRel(x: number, y: number) draw a quadradic curve from previous curve to point relative
• arcTo(rx: number, ry: number, xAxisRotation: number, largeArc: boolean, sweep: boolean, x: number, y: number ) draw arc from current position to point absolute
• arcToRel(rx: number, ry: number, xAxisRotation: number, largeArc: boolean, sweep: boolean, x: number, y: number ) draw arc from current position to point relative
• close() return the path as an Svg formatted string, closing the path
• end() return the path as an Svg formatted string

Note: I was inpired to write this while building an application requiring a lot of fancy SVG path drawing. I hope this will help you as it helped me.
