How to wait callback inside recursive function

Question

I have a recursive function:

let main = () => {
  ftp(_defaultPath, _start, (file, doc, name) => {
    parser(file, doc, name)
  })
}

The parser function:

module.exports = async function (file, doc, name) {
    await funcOne(file, doc)
    await funcTwo(file, doc, name)
    await funcThree(file, doc, name)
}

The callback its called inside the recursive function multiple times:

async function myFuntion(path, name, callback) {
   ...
   callback(file, doc, files[p][1])
   ...
}

The problem is I want to wait when i do callback like:

async function myFuntion(path, name, callback) {
   ...
   await callback(file, doc, files[p][1])
   ... next lines need to wait to finish callback
}

I trying to find how to do that.

It's possible to do that? thanks

I have done on this way:

I edit my main function with async inside ftp function:

let main = () => {
  ftp(_defaultPath, _start, async (file, doc, name) => {
    await parser(file, doc, name)
  })
}

I added the promise to parser function like that:

module.exports = function (file, doc, name) {
    return new Promise( async (resolve, reject) => {
        try {
            await funcOne(file, doc)
            await funcTwo(file, doc, name)
            await funcThree(file, doc, name)
        } catch(e) {
            return reject(e)
        }
        return resolve()
    }
}

Inside the recursive function I do the await.

await callback(file, doc, files[p][1])

Now waits as expected.

Thanks!
