Rendering SVG in React.js

I have an svg that I am trying to render in a React.js application. My working code looks like following

import React from 'react';

export default class App extends React.Component{
   render(){
      return(
         <svg
            width="100%"
            height="100%"
            xmlns="http://www.w3.org/2000/svg"
            xmlnsXlink="http://www.w3.org/1999/xlink"
         >
            <defs>
                <g id="Port">
                    <circle style={{ fill: "inherit" }} r="10" />
                </g>
            </defs>
            <use x="10" y="10" xlinkHref="#Port" style={{ fill: "blue" }} />
         </svg>
      )
   }
}

However, when I try to render svg from this file then nothing loads. I have camel cased stroke-width to strokeWidth and xmlns:xlink to xmlnsXlink but still no luck following this stackoverflow answer.

Am I missing something?

The code that doesn't work:

import React, { Component } from "react";

class App extends Component {
    render() {
        return (
            <svg
                width="100%"
                height="100%"
                xmlns="http://www.w3.org/2000/svg"
                xmlnsXlink="http://www.w3.org/1999/xlink"
            >
                <defs>
                    <g id="Port">
                        <path
                            fill="#CEE3F5"
                            stroke="#6E6E6E"
                            strokeWidth="0.4"

You are defining the height and width of the svg element in percentages. When I test your code it renders an element that is 150 pixels tall. Your <path>'s y coordinates are all between 300 and 400 pixels.

The SVG element is simply too short to show the content.

If I change 

        <svg
            width="100%"
            height="100%"

to

        <svg
            width="100%"
            height="500"

… then I can see your <path>.
