jgraph: a simple typescript-based fetch api for GraphQL, to make it a bit easier to use semantically

jgraph.ts

interface JraphOptions{
    url: string;
    method: "post" | "POST" | "get" | "GET" | "put" | "PUT" | "delete" | "DELETE";
    query: string;
}

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

try{
  const result = await jraph({
    url: 'http://localhost:4000/graphql', 
    method: 'POST', 
    query: '{language}'
  });
  console.dir(result);
  // result in the console should be `{ data: {langauge: "GraphQL"} }`
  // according to my example GraphQL server, which looks like the other file in this gist
}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'))
