What is GraphQL?
Schema definition language
Query language
Community of tools
Strong typing
type Message {
id: ID!
content: String
user: User
date: Int
}
type User {
id: ID!
name: String
email: String
avatarUrl: String
}
type Query {
messages: [Message]
}Strong typing
Help prevent errors
Improve the debugging experience
More explicit API (auto Docs)
Query only the data you need
{
messages {
id
content
user {
id
name
}
}
}
{
"data": {
"messages": [
{
"id": "0",
"content": "Are you enjoying the conference?",
"user": {
"id": "0",
"name": "Anne"
}
},
{
"id": "1",
"content": "Absolutely!",
"user": {
"id": "1",
"name": "Yoan"
}
}
]
}
}Query only the data you need
Reduce transfer size
No waterfall requests
Get predictable data shape
Clear and simple structure
Evolve your API
Add new fields
Deprecate old ones

Server tools
Feature-rich client
Strong community
Principles
By the community, for the community
Simplicity
Performance
Apollo Server
Apollo Server
import { createServer } from 'http'
import express from 'express'
import { makeExecutableSchema } from 'graphql-tools'
import { graphqlExpress } from 'apollo-server-express'
const typeDefs = `...`
const resolvers = {
Query: {
messages: (root, args, context) => database.questions()
},
}
const schema = makeExecutableSchema({ typeDefs, resolvers })
const app = express()
app.use(GRAPHQL_ENDPOINT, graphqlExpress({ schema }))
const server = createServer(app)
server.listen(PORT)Graphcool Yoga
import { GraphQLServer } from 'graphql-yoga'
const typeDefs = `...`
const resolvers = {
Query: {
messages: (root, args, context) => database.questions()
},
}
const server = new GraphQLServer({ typeDefs, resolvers })
