Using apollo in node - (no react)

Question

I want to use apollo to do some batch updates. And I need to start the batch script from node. eg node myscript.js

I can't figure out how to do this.  Is there a simple example that does what is described on the Get started: https://www.apollographql.com/docs/react/get-started/ but without react ?

(My code is working just fine when using react)

Answer 1

This is how to use Apollo Client ver 3.x from node vs using it from React

To use it from node you must import from @apollo/client/core in React you import from @apollo/client So initializing in node can look like this:

const STRAPIURI = "http://192.168.39.174:1337/graphql";
import fetch from 'cross-fetch';
import { ApolloClient, HttpLink, InMemoryCache } from '@apollo/client/core';

const apolloClient = new ApolloClient({
  link: new HttpLink({
    uri: `${STRAPIURI}`, fetch,
    credentials: 'same-origin', // Additional fetch() options like `credentials` or `headers`
  }),
  cache: new InMemoryCache()
});

You also need to import gql from the same location.

import { gql } from '@apollo/client/core';

First you need create an apollo client, very similar to react.

Check the below code.

import { ApolloClient } from 'apollo-client';
import fetch from 'node-fetch';
import { createHttpLink } from 'apollo-link-http';
import { setContext } from 'apollo-link-context';
import { InMemoryCache } from 'apollo-cache-inmemory';
import config from './config';

const httpLink = createHttpLink({
  uri: `${config.apiUrl}/graphql`,
  fetch,
});

const authLink = setContext(() => {
  const token = config.serverToken;
  return {
    headers: {
      Authorization: token,
    },
  };
});

const client = new ApolloClient({
  link: authLink.concat(httpLink),
  cache: new InMemoryCache(),
});


export default client;

Once is the client is done, you can use the below code to do a mutation

import gql from 'graphql-tag';

const mutation = gql(`mutation {
    CreateTodo(
      data: {
        task: "${task}"
      }
    ) {
      id
      task
    }
  }`);

const response = await client.mutate({mutation});

You can similarly use it for query as well. We are using node fetch to make the query or mutation.

Let me know if it helps.
