Use Import command in Node.js

Question

I have this node package installed https://github.com/jakearchibald/indexeddb-promised/blob/master/lib/idb.js, and am trying to use it.

I am trying to use this command:

(Import idb from 'idb')

Unfortunately, I get this error:

Uncaught SyntaxError: Unexpected token import

What should I do to solve this error?

You can use babel to transpile your code in ES6 syntax to ES5 in a transparent way for your develop. This is a part of my package.json in a demo app

 {
  "name": "**********",
  "version": "1.0.0",
  "description": "",
  "main": "server.js",
  "scripts": {
    "start": "nodemon server.js --exec babel-node --presets es2015,stage-2"
  },
  "author": "Borja Tur",
  "license": "ISC",
  "dependencies": {
    "bcrypt-nodejs": "0.0.3",
    "body-parser": "^1.15.1",
    "express": "^4.13.4",
    "jsonwebtoken": "^7.0.0",
    "mongoose": "^4.4.19",
    "morgan": "^1.7.0"
  },
  "devDependencies": {
    "babel": "^6.5.2",
    "babel-cli": "^6.9.0",
    "babel-preset-es2015": "^6.9.0",
    "babel-preset-stage-2": "^6.5.0"
  }
}

1. Install the same "devDependencies"
2. Install nodemon globally "npm install nodemon -g"
3. Configure your npm start command with the same of my package.json changing "server.js" with your entry file in the app
4. Run "npm start"

Then you can use import syntax
