Microsoft Graph for Office Addins using React JS

Hello !!! 

From last few weeks I am trying to build office addin using React Js.

Though ,I am new to React and Typescript,I was able to create a very basic application by installing node Js  ,Yo office and Typescript with React.

I now want to implement Microsoft Graph API in my application.

I tried some github solutions demonstrating Microsoft graph usage in React Js but all of them are using JSX and I want to understand how to implement it in my tsx(typecript) files. 

Any samples or any help appreciated.

Thanks and Regards,
