Version compatibility issue Azure functions' Node and DirectlineJS es6 exports - node.js

Question

End Goal:
To create Azure Function running Botframework-DirectlineJS with binding to Bot (Framework) using DirectLine secret.
Issue:
The above mentioned Botframework-DirectlineJS uses ES6 export and Azure Functions support Node 6.5.0 max doc. Hence the question how to import successfully the DirectlineJS in the index.js file of Azure function?
Error

import { DirectLine } from 'botframework-directlinejs';

Answer 1

Unfortunately it seems like import-export or node-hook doesn't play well with functions / edgejs (the environment we use to run node).
A couple options to try:
use babel to transpile es6 to es5 as a part of your deployment process.
write your function in typescript (index.ts) which will do import transpilation automatically - though this may fail for module dependencies, I haven't tried it out

Answer 2

You have three options: 1) Write your code using ES5, 2) setup a task runner (gulp/grunt/npm scripts) to convert your ES6+ code to ES5 using Babel, or 3) write your code in Typescript and compile it to ES5 via task runner/npm scripts.
The most straight-forward method would be: in your file importexportwrapper.js use require instead of import.
Example:
var directline = require('botframework-directlinejs');
Babel + Gulp Option
Install: npm install --save-dev gulp gulp-babel
Run:
var gulp = require("gulp");
var babel = require("gulp-babel");
gulp.task("default", function () {
return gulp.src("src/app.js") // your source files
.pipe(babel())
.pipe(gulp.dest("dist")); // your compiled output directory
});
