How to pass variables into graphql-tag from node.js function?

I have the following function:

import ApolloClient from 'apollo-boost'
import gql from 'graphql-tag'
import fetch from 'node-fetch'
global.fetch = fetch

const client = new ApolloClient({
    uri: 'myUri'
  })
const getPostsByCategory = async category => {
    const res = await client.query({
        query: gql`
          query articlesByCategory($id: String!) {
            postsByCategory(id: $id) {
              id
            }
          }
        `
      })
      console.log('res', res)
}

I want to invoke the function as:

await getPostsByCategory('news')

however I just can't understand how I pass the category variable into the query. I want to use qraphql-tag in my queries and not pass a simple tagged literal as the query.

You can use the variables key in your client.query function params as the following

const getPostsByCategory = async category => {
  const res = await client.query({
    query: gql`
      query articlesByCategory($id: String!) {
        postsByCategory(id: $id) {
          id
        }
      }
    `,
    variables: {
        id: category,
    },
  });
  console.log('res', res);
};
