mithril-graphql

A lightweight GraphQL client for the Mithril framework.

Usage

This module is best utilized with Babel (ES2015+) or CoffeeScript as they both support multiline strings.

ES5

var GraphClient = require('mithril-graphql');

var options = {
    url: '/graphql'
};

var query = 'query User($id: Int!) { user(id: $id) { id name } }';

var client = new GraphClient(options, queries);

client
    .get(query, { id: 1 })
    .then(function (response) {
        console.log(reponse.data);
    });

Babel (ES2015+)

const GraphClient = require('mithril-graphql');

const options = {
    url: '/graphql'
};

const query = `
    query User($id: Int!) { 
        user(id: $id) { 
            id 
            name 
        }
    }
';

const client = new GraphClient(options, queries);

client
    .get(query, { id: 1 })
    .then(response => {
        console.log(reponse.data);
    });

CoffeeScript

GraphClient = require('mithril-graphql')

options = {
    url: '/graphql'
}

query = """
    query User($id: Int!) { 
        user(id: $id) { 
            id 
            name 
        }
    }
"""

client = new GraphClient(options, queries)

client
    .get(query, { id: 1 })
    .then(response ->
        console.log(reponse.data)
    )

Additional notes

For optimal use, it is recommended that GraphQL queries utilize variables opposed to string interpolation. Before the client sends the request it will try to minify the query. Minification will strip out any carriage returns that are followed immediately by tabs or spaces.

Good

queries.js

const queries = {
    User: `
        query User($id: Int!) { 
            user(id: $id) { 
                id 
                name 
            }
        }
    `
};

graph.js

const GraphClient = require('mithril-graphql');
const queries = require('./queries');

const options = {
    url: '/graphql'
};

const client = new GraphClient(options);

client
    .get(queries.User, { id: 1 })
    .then((response) => {
        console.log(response.data);
    });

Bad

graph.js

const GraphClient = require('mithril-graphql');

const options = {
    url: '/graphql'
};

const id = 1;

const query = `
    query { 
        user(id: ${id}) { 
            id 
            name 
        }
    }
';

const client = new GraphClient(options, queries);

client
    .get(query)
    .then(response => {
        console.log(reponse.data);
    });

GraphClient

constructor(options)

Creates a new GraphClient.

get(query, [variables])

Sends a GraphQL query using the HTTP GET method.

post(query, [variables])

Sends a GraphQL query using the HTTP POST method.
