Simply:
// Default export (recommended)
export {default} from './MyClass'
// Default export with alias
export {default as d1} from './MyClass'
// In >ES7, it could be
export * from './MyClass'
// In >ES7, with alias
export * as d1 from './MyClass'
Or by functions names :
// export by function names
export { funcName1, funcName2, …} from './MyClass'
// export by aliases
export { funcName1 as f1, funcName2 as f2, …} from './MyClass'
