“unexpected token import” in Nodejs5 and babel?

Question

In js file, i used import to instead of require

import co from \'co\';

And tried to run it directly by nodejs since it said import is \'shi

Answer 1

I have done the following to overcome the problem (ex.js script)

problem

$ cat ex.js
import { Stack } from 'es-collections';
console.log("Successfully Imported");

$ node ex.js
/Users/nsaboo/ex.js:1
(function (exports, require, module, __filename, __dirname) { import { Stack } from 'es-collections';
                                                              ^^^^^^

solution

# npm package installation
npm install --save-dev babel-preset-env babel-cli es-collections

# .babelrc setup
$ cat .babelrc
{
  "presets": [
    ["env", {
      "targets": {
        "node": "current"
      }
    }]
  ]
}

# execution with node
$ npx babel ex.js --out-file ex-new.js
$ node ex-new.js
Successfully Imported

# or execution with babel-node
$ babel-node ex.js
Successfully Imported
