Managing GraphQL servers with AWS Fargate & Prisma Cloud
0 likes881 views
The document discusses managing GraphQL servers with AWS Fargate and Prisma Cloud. It begins with introductions to GraphQL and the core mechanics of a GraphQL server, including the schema, resolver functions, and setup. It then demonstrates building GraphQL servers with Prisma, and managing them using AWS Fargate and the Prisma Cloud service, which provides workflows for server management. Live demonstrations are included.

- 5. What is GraphQL? New API standard developed by Facebook Specficiation for type system & query language Core primitives: Query, Mutation & Subscription
- 6. Why use GraphQL? Strongly typed schema for your API Query exactly the data you need Rich ecosystem, smooth workflows and great community
- 7. query { user(id: “user123”) { name posts { title } } } HTTP POST { "data" :{ "user": { "name": "Sarah", "posts": [ { "title": "Join us for GraphQL Europe" }, { "title": "GraphQL is the future of APIs" }, ] } } }

- 10. Structure: The GraphQL Schema Behaviour: Resolver functions Setup: Engine, Server/Network, Middlewares… 3 parts of a GraphQL server 1 2 3
- 11. 1 The GraphQL Schema Strongly typed & written in GraphQL Schema Definition Language (SDL) Defines API capabilities (contract for client-server communication) Special root types: Query, Mutation, Subscription
- 12. Example: Hello World type Query { hello: String! } GRAPHQL SCHEMA query { hello } QUERY { “hello”: “Hello World” } RESPONSE
- 13. type User { id: ID! name: String! } type Query { user(id: ID!): User users: [User!]! } type Mutation { createUser(name: String!): User! updateUser(id: ID!, anme: String!): User deleteUser(id: ID!): User } Example: CRUD for User type
- 14. type User { id: ID! name: String! } type Query { user(id: ID!): User users: [User!]! } type Mutation { createUser(name: String!): User! updateUser(id: ID!, anme: String!): User deleteUser(id: ID!): User } query { user(id: “user123”) { name } } { “user”: { “name”: “Sarah” } } Example: CRUD for User type
- 15. 2 Resolver functions Concrete implementation of the API One resolver function per field in SDL schema Query execution: Invoke resolvers for all fields in query
- 16. type Query { hello: String! } GRAPHQL SCHEMA const resolvers = { Query: { hello: () => `Hello World` } } RESOLVER FUNCTIONS Example: Hello World
- 17. GRAPHQL SCHEMA type Query { user(id: ID!): User users: [User!]! } type Mutation { createUser(name: String!): User! updateUser(id: ID!, anme: String!): User deleteUser(id: ID!): User } type User { id: ID! name: String! } RESOLVER FUNCTIONS const resolvers = { Query: { user: (root, args) => db.getUser(args.id), users: () => db.getUsers() }, Mutation: { createUser: (root, args) => db.createUser(args.name), updateUser: (root, args) => db.updateUser(args.id, args.name), deleteUser: (root, args) => db.deleteUser(args.id), }, User: { id: (root) => root.id, name: (root) => root.name } } Example: CRUD for User type
