Amplify your web and mobile apps development. Full stack, cloud-powered.

As web and mobile have become the primary channel for engaging users, it’s critical that developers deliver applications with uncompromising user experience, performance, and scale. I will show you how to develop, release, and operate cloud-powered applications, at scale. We will navigate use cases like authentication, fine-grained access control, offline and real-time data, APIs (REST and GraphQL), AI/ML. We’ll dive into JavaScript, Kotlin, and Swift code to show how your applications can easily integrate with cloud-powered services.

3. We need an app to let our customers update preference settings – our competitors just launched the same thing, so I need it fast. I don’t want to pay a lot for it, especially when no one is using it. But remember that we’re growing, so make sure it scales great and is easy to manage and operate. And you’re on your own – sorry!

13. Amplify – a CLI to Provision Services $ amplify add auth $ amplify add storage $ amplify add api $ amplify push Add an Amazon Cognito User Pool Create and secure an Amazon S3 bucket Add an AWS AppSync or API Gateway Deploy via AWS CloudFormation
14. Amplify – A Set of Open-Source Libraries
15. Let’s enrich an iOS App
16. Initialise amplify $ amplify init $ amplify push
18. Provision the service $ amplify add auth $ amplify push
19. Modify our App : initialise Amplify.Logging.logLevel = .info try Amplify.add(plugin: AWSCognitoAuthPlugin()) try Amplify.configure() print("Amplify initialized")
20. Modify our App : add auth code _ = Amplify.Auth.signIn(username: username, password: password) { result in switch result { case .success(_): print("Sign in succeeded") case .failure(let error): print("Sign in failed \(error)") } }
22. $ amplify add auth && amplify push AWS Cloud Clients AWS Cognito User Pool Accounts Multi Factor Authentication Signup & Signin

28. AppSync, a runtime to execute the query query GetPost { getPosts(id: ”1”) { id title comments { content } author { name } } } query GetPost { getPosts(id: ”1”) { id title comments { content } author { name } } } Amazon EC2 { "data" : { "posts" : [ { "id" : 1, "title" : "Introduction to GraphQL", "comments" : [ { "content" : "I want GraphQL for my next App!" } ], "author" : { "name" : "Sébastien Stormacq" } } ] } } Amazon DynamoDB AWS Lambda
29. Provision the API $ amplify add api $ amplify push
30. $ amplify add api $ amplify add api ? Please select from one of the below mentioned services GraphQL ? Provide API name: amplifynotes ? Choose an authorization type for the API Amazon Cognito User Pool Using service: Cognito, provided by: awscloudformation The current configured provider is Amazon Cognito. ? Do you want to use the default authentication and security configuration? Yes, use the default configuration. Successfully added auth resource ? Do you have an annotated GraphQL schema? No ? Do you want a guided schema creation? true ? What best describes your project: Objects with fine-grained access control (e.g., a project management app with owner-based authorization) ? Do you want to edit the schema now? Yes Please edit the file in your editor: /<path>/amplify/backend/api/amplifynotes/schema.graphql ? Press enter to continue
31. A basic schema type LandmarkData { id: ID! name: String! category: String city: String state: String isFeatured: Boolean isFavorite: Boolean park: String coordinates: CoordinateData imageName: String }
