error TS1259: Module '"./node_modules/@types/express/index"' can only be default-imported using the 'esModuleInterop' flag

import * as React from 'react';

node.js typescript ts-node

You will need to move /server/src/tsconfig.json to /server/tsconfig.json - please note that you will need to MOVE, not COPY the tsconfig file.
