Window is not defined in node.js, sigma.js and typescript environment

I try to setup a sigma.js project with node.js written in TypeScript. The following reference error occurs after starting the node.js server with:

ts-node index.ts

The error seems to occur directly within the sigmautilsindex.js.

<nodejsproject>node_modulessigmautilsindex.js:125
    if (typeof window.devicePixelRatio !== "undefined")
    ^
ReferenceError: window is not defined

I tried to setup the typescript configuration as follows:

package.json

{
  ...
  "main": "index.ts",
  "scripts": {
    "dev": "nodemon ./index.ts",
    "test": "echo "Error: no test specified" && exit 1",
    "start": "ts-node index.ts"
  },
  "dependencies": {
    "@types/sigmajs": "^1.0.28",
    "express": "^4.17.2",
    "fs": "^0.0.1-security",
    "graphology": "^0.23.2",
    "graphology-components": "^1.5.2",
    "graphology-layout": "^0.5.0",
    "graphology-layout-forceatlas2": "^0.8.1",
    "papaparse": "^5.3.1",
    "path": "^0.12.7",
    "sigma": "^2.1.3",
    "xhr": "^2.6.0"
  },
  "devDependencies": {
    "@types/express": "^4.17.13",
    "tslint": "^6.1.3",
    "typescript": "^4.5.5"
  }
}

tsconfig.json

{
  "compilerOptions": {
    "module": "commonjs",
    "esModuleInterop": true,
    "target": "es6",
    "moduleResolution": "node",
    "sourceMap": true,
    "outDir": "dist",
    "lib": ["dom"]
  },
  "lib": [
    "es2015"
  ],
  "exclude":[
    "./node_modules"
  ]
}

The error is raised after instantiation of Sigma to draw the graph:

router.get('/', (request, response) => {
    
    response.sendFile(path.join(__dirname+'/views/index.html'));
    
    const file = fs.createReadStream(fileLocation);
    
    //Metadata were loaded and parsed
    Papa.parse<{ original_table: string; referenced_table: string }>(file, {
      download: true,
      header: true,
      delimiter: ';',
      complete: (results) => {
        const graph: Graph = new Graph();
            
        //Build the node with their entities as nodes
        results.data.forEach((line) => {

        /* process loaded data to create the graph */

        //Draw the graph within the browser
        const container = document.getElementById("network-container") as HTMLElement;
        
        new Sigma(graph, container); //error occurs right here
      },
    });
});
