ApolloClient is not a constructor (apollo-client with nodejs)

Question

I don't have any UI framework. Just a simple Nodejs script where I need to query a GraphQL.

Codes:

const ApolloClient = require('apollo-client')
const client = new ApolloClient()

Error message:

TypeError: ApolloClient is not a constructor

Package.json:

{
  ...

  "dependencies": {
    "apollo-client": "^2.4.13",
    "graphql": "^14.1.1",
    "graphql-tag": "^2.10.1"
  },
}

Node: v8.9.4

I googled a while people have this issue mainly because ApolloClient is no longer in react-apollo. You have to import it from 'apollo-client'

And I'm importing from apollo-client as const ApolloClient = require('apollo-client')

Any ideas? Thanks!

If you're using require, you can import it like this:

const ApolloClient = require('apollo-client').default

or like this

const { ApolloClient } = require('apollo-client')

Otherwise, you're importing the entire module, which itself is not a constructor.
