Local Schema Transport Layer for Lokka

This is a transport layer for wrapping Lokka around your graphql-js schema without going over the network.

Basic Usage

Install the package:

npm i --save lokka-transport-graphql-js
npm i --save lokka

This is how to send request to Facebook's SWAPI GraphQL Demo.

import GraphqlJSTransport from 'lokka-transport-graphql-js';
import schema from './path/to/my-schema'; // A valid instance of GraphQLSchema
const transport = new GraphqlJSTransport(schema);
transport.send(`
    {
      allFilms {
        films {
          title
        }
      }
    }
`).then(response => {
    console.log(JSON.stringify(response, null, 2));
});

Send context, rootValue, etc.

It's possible to send rootValue and context:

const transport = new GraphqlJSTransport(schema, { rootValue: myRootValue, context: myContext });

Error Handling

By default it will create and throw a new Error object using the first GraphQL error. Error handling can be customized with the handleErrors option. Check the default error handler in lib/index.js for an example.
