版本兼容性问题Azure函数的Node和DirectlineJS es6导出 [英] Version compatibility issue Azure functions' Node and DirectlineJS es6 exports

问题描述

要创建运行 Botframework-DirectlineJS 的Azure函数，并使用DirectLine秘密绑定到Bot (Framework)

To create Azure Function running Botframework-DirectlineJS with binding to Bot (Framework) using DirectLine secret.

上述Botframework-DirectlineJS使用ES6导出和Azure函数支持Node 6.5.0 max

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?

```

```

当前错误是在尝试使用 npm import-export

Currently the error was while trying to use npm import-export

• index.js

• index.js

require('import-export');
require ('./importexportwrapper');
let directLine = new DirectLine({
    secret: 'DirectlineSecretValue-here'
  }
  );```

importexportwrapper.js

importexportwrapper.js

import { DirectLine } from 'botframework-directlinejs';

推荐答案

您有三个选择:1)使用ES5编写代码，2)设置任务运行程序(gulp/grunt/npm脚本)，将ES6 +代码转换为使用Babel的ES5，或3)用Typescript编写代码，然后通过任务运行程序/npm脚本将其编译为ES5.

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.

最直接的方法是:在文件importexportwrapper.js中使用require而不是import.

The most straight-forward method would be: in your file importexportwrapper.js use require instead of import.

示例:

var directline = require('botframework-directlinejs');

Babel + Gulp选项

安装:npm install --save-dev gulp gulp-babel

运行:

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
});

了解有关Azure函数的更多信息这里是Node.js版本.
