How to import moment.js in ES6 using npm?

Question

I am using angular js and nodejs along with ES6. I want to import the moment.js in the angular js code. I did 'npm install moment --save'

Now I am able to see moment.js file in moment folder which is inside node modules.

and in my app.js file I have wriiten like this

'import moment from 'moment'; 

But if search something with date range It is showing error in console. Can anybody help me how to do this..?

Answer 1

Currently, to use ES6 module syntax, you need to use a transpiler e.g. Babel, since node.js and most browsers do not yet support ES6 module syntax.

Babel and webpack are great for this. Here is a nice example:

Once you have it configured properly, you invoke moment as such:

import moment from 'moment'; console.log(moment.now());

Since version 2.10.0 moment is written in ES6 :

import moment from './node_modules/moment/src/moment'; // Note the 'src/' to import the ES6 version and not the CJS build 

However for now it seems there is no way to import only a subset of functions, you have to import the whole thing.
