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?

• ChevCast: Node supports some parts of es6 but I don't believe import is one of them. I believe you still need babel or another transpiler for that.
• Mike Cluck: ^ is the correct answer. What you should do is write your code in CommonJS style: let idb = require('idb').
• Abdul Aziz Sabra: @Chev How can I use Babel with node.js to make this ?
• ChevCast: Wait, require is undefined? Wat? You really running node.js or are you running your javascript in the browser? Is window defined?
• Mike Cluck: @AbdulAzizSabra import doesn't work anywhere yet. Check out Browserify if you want to have modularized code that runs in the browser.

Answer 1

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

• Abdul Aziz Sabra: Thank you for your answer, but it is still not working with the same error.
• Borja Tur: "import" is used in lowercase maybe this cause the problem?
• Borja Tur: This is a sample use on my server.js => import express from 'express'
• Abdul Aziz Sabra: First I make This Command: npm install idp. and in my file I use this command : import idb from 'idp'; and I get this error : Uncaught SyntaxError: Unexpected token import
• Abdul Aziz Sabra: After install this "devDependencies" shoulde I make require for this packages? @Borjs Tur
