npx create-react-app MyAppName --typescript
npm install --save igniteui-react
npm install --save igniteui-react-charts igniteui-react-core
npm install --save igniteui-react-excel igniteui-react-core
npm install --save igniteui-react-gauges igniteui-react-core
npm install --save igniteui-react-grids igniteui-react-core
npm install --save igniteui-react-maps igniteui-react-core
npm install --save igniteui-react-spreadsheet igniteui-react-core
