Apollo Server

apollo-server

The Apollo Server library which allows you to focus on defining the shape of your data and how to fetch it.

The library used to build a chema and to execute queries on that schema.

Demos:

• app1.js:

Stand-alone Apollo GraphQL Server

$ nodemon app1.js
$ open localhost:4000/

using the GraphQL Playground:

{
    books {
        title
        author
    }
}

• app2.js

Apollo integrated with Express

const server = new ApolloServer({ typeDefs, resolvers})
const app = express()
server.applyMiddleware({app})

• app3.js

Rest API call from https://fourtonfish.com/

• app4.js

Automatic Persisted Queries apollo-server-cache-memcached

• CDN Integration

Apollo Server works well with a Content-Distribution Network to cache full GraphQL query results. Apollo Server provides cache-control headers that a CDN uses to determine how long a request should be cached. For subsequent requests, the result will be served directly from the CDN’s cache. A CDN paired with Apollo Server’s persisted queries is especially powerful, since GraphQL operations can be shortened and sent with a HTTP GET request. To enable caching and a CDN in Apollo Server, follow the Performance Guide.
