How to fetch API data to Graphql schema

I want to call to API, get json data and set it to resolvers Query in Graphql. So far I managed to working Graphql server and get call to API. This is my code so far 

//resolvers.js
//var fetch = require('node-fetch');
var request = require("request");


var options = { method: 'GET',
    url: 'http://mydomain.con/index.php/rest/V1/products/24-MB01',
    headers:
        { 'postman-token': 'mytoken',
            'cache-control': 'no-cache',
            'content-type': 'application/json',
            authorization: 'Bearer mytoken' } };

const links = request(options, function (error, response, body) {
    if (error) throw new Error(error);
    //body = json data
    //console.log(body);

});

module.exports = {
    Query: {
        //set data to Query
        allLinks: () => links,
},
};

I dont know how to set the body parameter which contain json data to Query. I have also same data on "http://localhost/src/apicall.php" but this is not working with node-fetch (or Im making mistakes). Api is from magento2.

You were close !

What you are doing right now is sending the links request right when your application starts. You don't want that ; you want to send the request when the allLinks field is requested in GraphQL.

So what you need is to have in the allLinks field a function making the request to your API, and returning the response.

If you return a Promise within the allLinks field, it will wait upon completion to use the returned value as an answer.

So, putting it all together:

...

const getAllLinks = () => {
  return new Promise((resolve, reject) => {
    request(options, function (error, response, body) {
      if (error) reject(error);
      else resolve(body);
    });
  });
};

module.exports = {
  Query: {
    //set data to Query
    allLinks: getAllLinks,
  },
};
