How can I group and export multiple functions in nodejs?

I am trying to group all my util functions in utils.js:

async function example1 () {

    return 'example 1'

}



async function example2 () {

    return 'example 2'

}



module.exports = { example1, example2 }

And then be imported in home.js:

  import { example1, example2 } from '../utils'



  router.get('/', async(ctx, next) => {

    console.log(example1()) // Promise { 'example 1' }



  })

I thought I would get 'example 1' for the test case above?

Any ideas?

This would be my solution for your exporting problem! And don't mix es5 exports with es6 imports, that can get very weird - sometimes!

export const example1 = async () => {

   return 'example 1'

}



export const example2 = async () => {

   return 'example 2'

}





// other file

import { example1, example2 } from '../../example'

return example1()

Nevertheless if you have to mix them, just let me know! We can find a solution for this aswell!
