GraphQL

Using GraphQL with Funcatron can be done easily by pulling in the express-graphql package.

First, install the necessary modules:

yarn add express-graphql graphql

const { e2f, funcatron } = require('funcatron')
const graphqlHTTP = require('express-graphql')
const TestSchema = require('./TestSchema')

// Initialize the GraphQL handler with your schema (see below)
const graphQL = graphqlHTTP({
    schema: TestSchema,
    graphiql: true
})

funcatron([
    {
        path: "/graphql",
        handler: e2f(graphQL)
    }
]).listen(8000)

Here's a very basic test schema:

// TestSchema.js
const {
    graphql,
    GraphQLSchema,
    GraphQLObjectType,
    GraphQLString
} = require('graphql')

module.exports = new GraphQLSchema({
    query: new GraphQLObjectType({
        name: 'TestQuery',
        fields: {
            hello: {
                type: GraphQLString,
                resolve() {
                    return 'world';
                }
            }
        }
    })
})

That's it! You should be able to hit localhost:8000/graphql and see the GraphiQL interface.
