jraph - a simple fetch wrapper for GraphQL, just to tidy up the look of things!

jraph.ts

async function jraph(argv: JraphOptions){
    let url = argv.url;
    let headers = { 'Content-Type': 'application/json' }
    let body = JSON.stringify({query: argv.query});
    let fetch_options = {
        method: argv.method,
        headers,
        body
    };
    //returns request as JSON
    // return (await fetch(url, fetch_options).then(res=>res.json())).data;
    return fetch(url, fetch_options).then(res=>res.json());
}

//Example Usage

try {
   const result = await jraph({
     url: 'http://localhost:4000/graphql',
     method: 'POST',
     query: '{language}'
   });
   console.dir(result);
  //Output should be: `{ data: { langauge: "GraphQL" }}`
} catch (e) {
   console.error('err', e);
}

server.js

const express = require('express');
const { graphql, buildSchema } = require('graphql');
const graphqlHTTP = require('express-graphql');
const cors = require('cors');

const schema = buildSchema(`
  type Query {
    language: String
  }
`)

const rootValue = {
    language: () => 'GraphQL'
}

const app = express()
app.use(cors())
app.use('/graphql', graphqlHTTP({
        rootValue, schema, graphiql: true
    })
)

app.listen(4000, () => console.log('Listening on 4000'))
