v2.274.0

AWS Amplify Construct Library ​

Version 2.274.0-alpha.0

Separate package

@aws-cdk/aws-amplify-alpha is not part of aws-cdk-lib — install it separately:

sh
npm install @aws-cdk/aws-amplify-alpha
pip install aws-cdk.aws-amplify-alpha

This module is experimental (alpha): its API may change in any release, without a major version bump.


cdk-constructs: Experimental

The APIs of higher level constructs in this module are experimental and under active development. They are subject to non-backward compatible changes or removal in any future version. These are not subject to the Semantic Versioning model and breaking changes will be announced in the release notes. This means that while you may use them, you may need to update your source code when upgrading to a newer version of this package.


The AWS Amplify Console provides a Git-based workflow for deploying and hosting fullstack serverless web applications. A fullstack serverless app consists of a backend built with cloud resources such as GraphQL or REST APIs, file and data storage, and a frontend built with single page application frameworks such as React, Angular, Vue, or Gatsby.

Setting up an app with branches, custom rules and a domain ​

To set up an Amplify Console app, define an App:

ts
import * as codebuild from 'aws-cdk-lib/aws-codebuild';

const amplifyApp = new amplify.App(this, 'MyApp', {
  sourceCodeProvider: new amplify.GitHubSourceCodeProvider({
    owner: '<user>',
    repository: '<repo>',
    oauthToken: SecretValue.secretsManager('my-github-token'),
  }),
  buildSpec: codebuild.BuildSpec.fromObjectToYaml({
    // Alternatively add a `amplify.yml` to the repo
    version: '1.0',
    frontend: {
      phases: {
        preBuild: {
          commands: [
            'yarn',
          ],
        },
        build: {
          commands: [
            'yarn build',
          ],
        },
      },
      artifacts: {
        baseDirectory: 'public',
        files:
        - '**/*',
      },
    },
  }),
});
python
import aws_cdk.aws_codebuild as codebuild


amplify_app = amplify.App(self, "MyApp",
    source_code_provider=amplify.GitHubSourceCodeProvider(
        owner="<user>",

        }
    })
)

To connect your App to GitLab, use the GitLabSourceCodeProvider:

ts
const amplifyApp = new amplify.App(this, 'MyApp', {
  sourceCodeProvider: new amplify.GitLabSourceCodeProvider({
    owner: '<user>',
    repository: '<repo>',
    oauthToken: SecretValue.secretsManager('my-gitlab-token'),
  }),
});
python
amplify_app = amplify.App(self, "MyApp",
    source_code_provider=amplify.GitLabSourceCodeProvider(
        owner="<user>",
        repository="<repo>",
        oauth_token=SecretValue.secrets_manager("my-gitlab-token")
    )
)
java
App amplifyApp = App.Builder.create(this, "MyApp")
        .sourceCodeProvider(GitLabSourceCodeProvider.Builder.create()
                .owner("<user>")
                .repository("<repo>")
                .oauthToken(SecretValue.secretsManager("my-gitlab-token"))
                .build())
        .build();
csharp
var amplifyApp = new App(this, "MyApp", new AppProps {
    SourceCodeProvider = new GitLabSourceCodeProvider(new GitLabSourceCodeProviderProps {
        Owner = "<user>",
        Repository = "<repo>",
        OauthToken = SecretValue.SecretsManager("my-gitlab-token")
    })
});
go
amplifyApp := amplify.NewApp(this, jsii.String("MyApp"), &AppProps{
	SourceCodeProvider: amplify.NewGitLabSourceCodeProvider(&GitLabSourceCodeProviderProps{
		Owner: jsii.String("<user>"),
		Repository: jsii.String("<repo>"),
		OauthToken: awscdk.SecretValue_SecretsManager(jsii.String("my-gitlab-token")),
	}),
})

To connect your App to CodeCommit, use the CodeCommitSourceCodeProvider:

ts
import * as codecommit from 'aws-cdk-lib/aws-codecommit';

const repository = new codecommit.Repository(this, 'Repo', {
  repositoryName: 'my-repo',
});

const amplifyApp = new amplify.App(this, 'App', {
  sourceCodeProvider: new amplify.CodeCommitSourceCodeProvider({ repository }),
});
python
import aws_cdk.aws_codecommit as codecommit


repository = codecommit.Repository(self, "Repo",
    repository_name="my-repo"
)

amplify_app = amplify.App(self, "App",
    source_code_provider=amplify.CodeCommitSourceCodeProvider(repository=repository)
)
java
import software.amazon.awscdk.services.codecommit.*;


Repository repository = Repository.Builder.create(this, "Repo")
        .repositoryName("my-repo")
        .build();

App amplifyApp = App.Builder.create(this, "App")
        .sourceCodeProvider(CodeCommitSourceCodeProvider.Builder.create().repository(repository).build())
        .build();
csharp
using Amazon.CDK.AWS.CodeCommit;


var repository = new Repository(this, "Repo", new RepositoryProps {
    RepositoryName = "my-repo"
});

var amplifyApp = new App(this, "App", new AppProps {
    SourceCodeProvider = new CodeCommitSourceCodeProvider(new CodeCommitSourceCodeProviderProps { Repository = repository })
});
go
import codecommit "github.com/aws/aws-cdk-go/awscdk"


repository := codecommit.NewRepository(this, jsii.String("Repo"), &RepositoryProps{
	RepositoryName: jsii.String("my-repo"),
})

amplifyApp := amplify.NewApp(this, jsii.String("App"), &AppProps{
	SourceCodeProvider: amplify.NewCodeCommitSourceCodeProvider(&CodeCommitSourceCodeProviderProps{
		Repository: *Repository,
	}),
})

The IAM role associated with the App will automatically be granted the permission to pull the CodeCommit repository.

Add branches:

ts
declare const amplifyApp: amplify.App;

const main = amplifyApp.addBranch('main'); // `id` will be used as repo branch name
const dev = amplifyApp.addBranch('dev', {
  performanceMode: true, // optional, enables performance mode
});
dev.addEnvironment('STAGE', 'dev');
python
# amplify_app: amplify.App


main = amplify_app.add_branch("main") # `id` will be used as repo branch name
dev = amplify_app.add_branch("dev",
    performance_mode=True
)
dev.add_environment("STAGE", "dev")
java
App amplifyApp;


Branch main = amplifyApp.addBranch("main"); // `id` will be used as repo branch name
Branch dev = amplifyApp.addBranch("dev", BranchOptions.builder()
        .performanceMode(true)
        .build());
dev.addEnvironment("STAGE", "dev");
csharp
App amplifyApp;


var main = amplifyApp.AddBranch("main"); // `id` will be used as repo branch name
var dev = amplifyApp.AddBranch("dev", new BranchOptions {
    PerformanceMode = true
});
dev.AddEnvironment("STAGE", "dev");
go
var amplifyApp App


main := amplifyApp.AddBranch(jsii.String("main")) // `id` will be used as repo branch name
dev := amplifyApp.AddBranch(jsii.String("dev"), &BranchOptions{
	PerformanceMode: jsii.Boolean(true),
})
dev.AddEnvironment(jsii.String("STAGE"), jsii.String("dev"))

Auto build and pull request preview are enabled by default.

Add custom rules for redirection:

ts
import { CustomRule } from '@aws-cdk/aws-amplify-alpha';

declare const amplifyApp: amplify.App;
amplifyApp.addCustomRule(new CustomRule({
  source: '/docs/specific-filename.html',
  target: '/documents/different-filename.html',
  status: amplify.RedirectStatus.TEMPORARY_REDIRECT,
}));
python
from aws_cdk.aws_amplify_alpha import CustomRule

# amplify_app: amplify.App

amplify_app.add_custom_rule(CustomRule(
    source="/docs/specific-filename.html",
    target="/documents/different-filename.html",
    status=amplify.RedirectStatus.TEMPORARY_REDIRECT
))
java
import software.amazon.awscdk.services.amplify.alpha.CustomRule;

App amplifyApp;

amplifyApp.addCustomRule(CustomRule.Builder.create()
        .source("/docs/specific-filename.html")
        .target("/documents/different-filename.html")
        .status(RedirectStatus.TEMPORARY_REDIRECT)
        .build());
csharp
using Amazon.CDK.AWS.Amplify.Alpha;

App amplifyApp;

amplifyApp.AddCustomRule(new CustomRule(new CustomRuleOptions {
    Source = "/docs/specific-filename.html",
    Target = "/documents/different-filename.html",
    Status = RedirectStatus.TEMPORARY_REDIRECT
}));
go
import "github.com/aws/aws-cdk-go/awscdkamplifyalpha"

var amplifyApp App

amplifyApp.AddCustomRule(awscdkamplifyalpha.NewCustomRule(&CustomRuleOptions{
	Source: jsii.String("/docs/specific-filename.html"),
	Target: jsii.String("/documents/different-filename.html"),
	Status: amplify.RedirectStatus_TEMPORARY_REDIRECT,
}))

When working with a single page application (SPA), use the CustomRule.SINGLE_PAGE_APPLICATION_REDIRECT to set up a 200 rewrite for all files to index.html except for the following file extensions: css, gif, ico, jpg, js, png, txt, svg, woff, ttf, map, json, webmanifest.

ts
declare const mySinglePageApp: amplify.App;

mySinglePageApp.addCustomRule(amplify.CustomRule.SINGLE_PAGE_APPLICATION_REDIRECT);
python
# my_single_page_app: amplify.App


my_single_page_app.add_custom_rule(amplify.CustomRule.SINGLE_PAGE_APPLICATION_REDIRECT)
java
App mySinglePageApp;


mySinglePageApp.addCustomRule(CustomRule.SINGLE_PAGE_APPLICATION_REDIRECT);
csharp
App mySinglePageApp;


mySinglePageApp.AddCustomRule(CustomRule.SINGLE_PAGE_APPLICATION_REDIRECT);
go
var mySinglePageApp App


mySinglePageApp.AddCustomRule(amplify.CustomRule_SINGLE_PAGE_APPLICATION_REDIRECT())

Add a domain and map sub domains to branches:

ts
declare const amplifyApp: amplify.App;
declare const main: amplify.Branch;
declare const dev: amplify.Branch;

const domain = amplifyApp.addDomain('example.com', {
  enableAutoSubdomain: true, // in case subdomains should be auto registered for branches
  autoSubdomainCreationPatterns: ['*', 'pr*'], // regex for branches that should auto register subdomains
});
domain.mapRoot(main); // map main branch to domain root
domain.mapSubDomain(main, 'www');
domain.mapSubDomain(dev); // sub domain prefix defaults to branch name
python
# amplify_app: amplify.App
# main: amplify.Branch
# dev: amplify.Branch


domain = amplify_app.add_domain("example.com",
    enable_auto_subdomain=True,  # in case subdomains should be auto registered for branches
    auto_subdomain_creation_patterns=["*", "pr*"]
)
domain.map_root(main) # map main branch to domain root
domain.map_sub_domain(main, "www")
domain.map_sub_domain(dev)
java
App amplifyApp;
Branch main;
Branch dev;


Domain domain = amplifyApp.addDomain("example.com", DomainOptions.builder()
        .enableAutoSubdomain(true) // in case subdomains should be auto registered for branches
        .autoSubdomainCreationPatterns(List.of("*", "pr*"))
        .build());
domain.mapRoot(main); // map main branch to domain root
domain.mapSubDomain(main, "www");
domain.mapSubDomain(dev);
csharp
App amplifyApp;
Branch main;
Branch dev;


var domain = amplifyApp.AddDomain("example.com", new DomainOptions {
    EnableAutoSubdomain = true,  // in case subdomains should be auto registered for branches
    AutoSubdomainCreationPatterns = new [] { "*", "pr*" }
});
domain.MapRoot(main); // map main branch to domain root
domain.MapSubDomain(main, "www");
domain.MapSubDomain(dev);
go
var amplifyApp App
var main Branch
var dev Branch


domain := amplifyApp.AddDomain(jsii.String("example.com"), &DomainOptions{
	EnableAutoSubdomain: jsii.Boolean(true),
	 // in case subdomains should be auto registered for branches
	AutoSubdomainCreationPatterns: []*string{
		jsii.String("*"),
		jsii.String("pr*"),
	},
})
domain.MapRoot(main) // map main branch to domain root
domain.MapSubDomain(main, jsii.String("www"))
domain.MapSubDomain(dev)

To specify a custom certificate for your custom domain use the customCertificate property:

ts
declare const customCertificate: acm.Certificate;
declare const amplifyApp: amplify.App;

const domain = amplifyApp.addDomain('example.com', {
  customCertificate, // set your custom certificate
});
python
# custom_certificate: acm.Certificate
# amplify_app: amplify.App


domain = amplify_app.add_domain("example.com",
    custom_certificate=custom_certificate
)
java
Certificate customCertificate;
App amplifyApp;


Domain domain = amplifyApp.addDomain("example.com", DomainOptions.builder()
        .customCertificate(customCertificate)
        .build());
csharp
Certificate customCertificate;
App amplifyApp;


var domain = amplifyApp.AddDomain("example.com", new DomainOptions {
    CustomCertificate = customCertificate
});
go
var customCertificate Certificate
var amplifyApp App


domain := amplifyApp.AddDomain(jsii.String("example.com"), &DomainOptions{
	CustomCertificate: CustomCertificate,
})

Restricting access ​

Password protect the app with basic auth by specifying the basicAuth prop.

Use BasicAuth.fromCredentials when referencing an existing secret:

ts
const amplifyApp = new amplify.App(this, 'MyApp', {
  sourceCodeProvider: new amplify.GitHubSourceCodeProvider({
    owner: '<user>',
    repository: '<repo>',
    oauthToken: SecretValue.secretsManager('my-github-token'),
  }),
  basicAuth: amplify.BasicAuth.fromCredentials('username', SecretValue.secretsManager('my-github-token')),
});
python
amplify_app = amplify.App(self, "MyApp",
    source_code_provider=amplify.GitHubSourceCodeProvider(
        owner="<user>",
        repository="<repo>",
        oauth_token=SecretValue.secrets_manager("my-github-token")
    ),
    basic_auth=amplify.BasicAuth.from_credentials("username", SecretValue.secrets_manager("my-github-token"))
)
java
App amplifyApp = App.Builder.create(this, "MyApp")
        .sourceCodeProvider(GitHubSourceCodeProvider.Builder.create()
                .owner("<user>")
                .repository("<repo>")
                .oauthToken(SecretValue.secretsManager("my-github-token"))
                .build())
        .basicAuth(BasicAuth.fromCredentials("username", SecretValue.secretsManager("my-github-token")))
        .build();
csharp
var amplifyApp = new App(this, "MyApp", new AppProps {
    SourceCodeProvider = new GitHubSourceCodeProvider(new GitHubSourceCodeProviderProps {
        Owner = "<user>",
        Repository = "<repo>",
        OauthToken = SecretValue.SecretsManager("my-github-token")
    }),
    BasicAuth = BasicAuth.FromCredentials("username", SecretValue.SecretsManager("my-github-token"))
});
go
amplifyApp := amplify.NewApp(this, jsii.String("MyApp"), &AppProps{
	SourceCodeProvider: amplify.NewGitHubSourceCodeProvider(&GitHubSourceCodeProviderProps{
		Owner: jsii.String("<user>"),
		Repository: jsii.String("<repo>"),
		OauthToken: awscdk.SecretValue_SecretsManager(jsii.String("my-github-token")),
	}),
	BasicAuth: amplify.BasicAuth_FromCredentials(jsii.String("username"), awscdk.SecretValue_*SecretsManager(jsii.String("my-github-token"))),
})

Use BasicAuth.fromGeneratedPassword to generate a password in Secrets Manager:

ts
const amplifyApp = new amplify.App(this, 'MyApp', {
  sourceCodeProvider: new amplify.GitHubSourceCodeProvider({
    owner: '<user>',
    repository: '<repo>',
    oauthToken: SecretValue.secretsManager('my-github-token'),
  }),
  basicAuth: amplify.BasicAuth.fromGeneratedPassword('username'),
});
python
amplify_app = amplify.App(self, "MyApp",
    source_code_provider=amplify.GitHubSourceCodeProvider(
        owner="<user>",
        repository="<repo>",
        oauth_token=SecretValue.secrets_manager("my-github-token")
    ),
    basic_auth=amplify.BasicAuth.from_generated_password("username")
)
java
App amplifyApp = App.Builder.create(this, "MyApp")
        .sourceCodeProvider(GitHubSourceCodeProvider.Builder.create()
                .owner("<user>")
                .repository("<repo>")
                .oauthToken(SecretValue.secretsManager("my-github-token"))
                .build())
        .basicAuth(BasicAuth.fromGeneratedPassword("username"))
        .build();
csharp
var amplifyApp = new App(this, "MyApp", new AppProps {
    SourceCodeProvider = new GitHubSourceCodeProvider(new GitHubSourceCodeProviderProps {
        Owner = "<user>",
        Repository = "<repo>",
        OauthToken = SecretValue.SecretsManager("my-github-token")
    }),
    BasicAuth = BasicAuth.FromGeneratedPassword("username")
});
go
amplifyApp := amplify.NewApp(this, jsii.String("MyApp"), &AppProps{
	SourceCodeProvider: amplify.NewGitHubSourceCodeProvider(&GitHubSourceCodeProviderProps{
		Owner: jsii.String("<user>"),
		Repository: jsii.String("<repo>"),
		OauthToken: awscdk.SecretValue_SecretsManager(jsii.String("my-github-token")),
	}),
	BasicAuth: amplify.BasicAuth_FromGeneratedPassword(jsii.String("username")),
})

Basic auth can be added to specific branches:

ts
declare const amplifyApp: amplify.App;
amplifyApp.addBranch('feature/next', {
  basicAuth: amplify.BasicAuth.fromGeneratedPassword('username'),
});
python
# amplify_app: amplify.App

amplify_app.add_branch("feature/next",
    basic_auth=amplify.BasicAuth.from_generated_password("username")
)
java
App amplifyApp;

amplifyApp.addBranch("feature/next", BranchOptions.builder()
        .basicAuth(BasicAuth.fromGeneratedPassword("username"))
        .build());
csharp
App amplifyApp;

amplifyApp.AddBranch("feature/next", new BranchOptions {
    BasicAuth = BasicAuth.FromGeneratedPassword("username")
});
go
var amplifyApp App

amplifyApp.AddBranch(jsii.String("feature/next"), &BranchOptions{
	BasicAuth: amplify.BasicAuth_FromGeneratedPassword(jsii.String("username")),
})

Automatically creating and deleting branches ​

Use the autoBranchCreation and autoBranchDeletion props to control creation/deletion of branches:

ts
const amplifyApp = new amplify.App(this, 'MyApp', {
  sourceCodeProvider: new amplify.GitHubSourceCodeProvider({
    owner: '<user>',
    repository: '<repo>',
    oauthToken: SecretValue.secretsManager('my-github-token'),
  }),
  autoBranchCreation: { // Automatically connect branches that match a pattern set
    patterns: ['feature/*', 'test/*'],
  },
  autoBranchDeletion: true, // Automatically disconnect a branch when you delete a branch from your repository
});
python
amplify_app = amplify.App(self, "MyApp",
    source_code_provider=amplify.GitHubSourceCodeProvider(
        owner="<user>",
        repository="<repo>",
        oauth_token=SecretValue.secrets_manager("my-github-token")
    ),
    auto_branch_creation=amplify.AutoBranchCreation( # Automatically connect branches that match a pattern set
        patterns=["feature/*", "test/*"]),
    auto_branch_deletion=True
)
java
App amplifyApp = App.Builder.create(this, "MyApp")
        .sourceCodeProvider(GitHubSourceCodeProvider.Builder.create()
                .owner("<user>")
                .repository("<repo>")
                .oauthToken(SecretValue.secretsManager("my-github-token"))

Adding custom response headers ​

Use the customResponseHeaders prop to configure custom response headers for an Amplify app:

ts
const amplifyApp = new amplify.App(this, 'App', {
  sourceCodeProvider: new amplify.GitHubSourceCodeProvider({
    owner: '<user>',
    repository: '<repo>',
    oauthToken: SecretValue.secretsManager('my-github-token'),
  }),
  customResponseHeaders: [
    {
      pattern: '*.json',
      headers: {
        'custom-header-name-1': 'custom-header-value-1',
        'custom-header-name-2': 'custom-header-value-2',
      },
    },
    {
      pattern: '/path/*',
      headers: {
        'custom-header-name-1': 'custom-header-value-2',
      },
    },
  ],
});
python
amplify_app = amplify.App(self, "App",
    source_code_provider=amplify.GitHubSourceCodeProvider(
        owner="<user>",
        repository="<repo>",
        oauth_token=SecretValue.secrets_manager("my-github-token")

    custom_response_headers=[amplify.CustomResponseHeader(

            "custom-header-name-2": "custom-header-value-2"
        }
    ), amplify.CustomResponseHeader(
        pattern="/path/*",
        headers={

        }
    )
    ]
)
java

        .sourceCodeProvider(GitHubSourceCodeProvider.Builder.create()
                .owner("<user>")
                .repository("<repo>")
                .oauthToken(SecretValue.secretsManager("my-github-token"))

        }
    } }
});
go

			Pattern: jsii.String("/path/*"),
			Headers: map[string]*string{
				"custom-header-name-1": jsii.String("custom-header-value-2"),

		},
	},
})

If the app uses a monorepo structure, define which appRoot from the build spec the custom response headers should apply to by using the appRoot property:

ts

Configure server side rendering when hosting app ​

Setting the platform field on the Amplify App construct can be used to control whether the app will host only static assets or server side rendered assets in addition to static. By default, the value is set to WEB (static only), however, server side rendering can be turned on by setting to WEB_COMPUTE as follows:

ts
const amplifyApp = new amplify.App(this, 'MyApp', {
  platform: amplify.Platform.WEB_COMPUTE,
});
python
amplify_app = amplify.App(self, "MyApp",
    platform=amplify.Platform.WEB_COMPUTE
)
java
App amplifyApp = App.Builder.create(this, "MyApp")
        .platform(Platform.WEB_COMPUTE)
        .build();
csharp
var amplifyApp = new App(this, "MyApp", new AppProps {
    Platform = Platform.WEB_COMPUTE
});
go
amplifyApp := amplify.NewApp(this, jsii.String("MyApp"), &AppProps{
	Platform: amplify.Platform_WEB_COMPUTE,
})

Compute role ​

This integration, enables you to assign an IAM role to the Amplify SSR Compute service to allow your server-side rendered (SSR) application to securely access specific AWS resources based on the role's permissions.

For example, you can allow your app's SSR compute functions to securely access other AWS services or resources, such as Amazon Bedrock or an Amazon S3 bucket, based on the permissions defined in the assigned IAM role.

For more information, see Adding an SSR Compute role to allow access to AWS resources.

By default, a new role is created when platform is Platform.WEB_COMPUTE or Platform.WEB_DYNAMIC. If you want to assign an IAM role to the APP, set compute to the role:

ts
declare const computeRole: iam.Role;

const amplifyApp = new amplify.App(this, 'MyApp', {
  platform: amplify.Platform.WEB_COMPUTE,
  computeRole,
});
python
# compute_role: iam.Role


amplify_app = amplify.App(self, "MyApp",
    platform=amplify.Platform.WEB_COMPUTE,
    compute_role=compute_role
)
java
Role computeRole;


App amplifyApp = App.Builder.create(this, "MyApp")
        .platform(Platform.WEB_COMPUTE)
        .computeRole(computeRole)
        .build();
csharp
Role computeRole;


var amplifyApp = new App(this, "MyApp", new AppProps {
    Platform = Platform.WEB_COMPUTE,
    ComputeRole = computeRole
});
go
var computeRole Role


amplifyApp := amplify.NewApp(this, jsii.String("MyApp"), &AppProps{
	Platform: amplify.Platform_WEB_COMPUTE,
	ComputeRole: ComputeRole,
})

It is also possible to override the compute role for a specific branch by setting computeRole in Branch:

ts
declare const computeRole: iam.Role;
declare const amplifyApp: amplify.App

const branch = amplifyApp.addBranch("dev", { computeRole });
python
# compute_role: iam.Role
# amplify_app: amplify.App


branch = amplify_app.add_branch("dev", compute_role=compute_role)
java
Role computeRole;
App amplifyApp;


Branch branch = amplifyApp.addBranch("dev", BranchOptions.builder().computeRole(computeRole).build());
csharp
Role computeRole;
App amplifyApp;


var branch = amplifyApp.AddBranch("dev", new BranchOptions { ComputeRole = computeRole });
go
var computeRole Role
var amplifyApp App


branch := amplifyApp.AddBranch(jsii.String("dev"), &BranchOptions{
	ComputeRole: ComputeRole,
})

Cache Config ​

Amplify uses Amazon CloudFront to manage the caching configuration for your hosted applications. A cache configuration is applied to each app to optimize for the best performance.

Setting the cacheConfigType field on the Amplify App construct can be used to control cache configuration. By default, the value is set to AMPLIFY_MANAGED. If you want to exclude all cookies from the cache key, set AMPLIFY_MANAGED_NO_COOKIES.

For more information, see Managing the cache configuration for an app.

ts
const amplifyApp = new amplify.App(this, 'MyApp', {
  cacheConfigType: amplify.CacheConfigType.AMPLIFY_MANAGED_NO_COOKIES,
});
python
amplify_app = amplify.App(self, "MyApp",
    cache_config_type=amplify.CacheConfigType.AMPLIFY_MANAGED_NO_COOKIES
)
java
App amplifyApp = App.Builder.create(this, "MyApp")
        .cacheConfigType(CacheConfigType.AMPLIFY_MANAGED_NO_COOKIES)
        .build();
csharp
var amplifyApp = new App(this, "MyApp", new AppProps {
    CacheConfigType = CacheConfigType.AMPLIFY_MANAGED_NO_COOKIES
});
go
amplifyApp := amplify.NewApp(this, jsii.String("MyApp"), &AppProps{
	CacheConfigType: amplify.CacheConfigType_AMPLIFY_MANAGED_NO_COOKIES,
})

Build Compute Type ​

You can specify the build compute type by setting the buildComputeType property.

For more information, see Configuring the build instance for an Amplify application.

ts
const amplifyApp = new amplify.App(this, 'MyApp', {
  buildComputeType: amplify.BuildComputeType.LARGE_16GB,
});
python
amplify_app = amplify.App(self, "MyApp",
    build_compute_type=amplify.BuildComputeType.LARGE_16GB
)
java
App amplifyApp = App.Builder.create(this, "MyApp")
        .buildComputeType(BuildComputeType.LARGE_16GB)
        .build();

});

	BuildComputeType: amplify.BuildComputeType_LARGE_16GB,
})

Deploying Assets ​

sourceCodeProvider is optional; when this is not specified the Amplify app can be deployed to using .zip packages. The asset property can be used to deploy S3 assets to Amplify as part of the CDK:

ts
import * as assets from 'aws-cdk-lib/aws-s3-assets';

declare const asset: assets.Asset;
declare const amplifyApp: amplify.App;
const branch = amplifyApp.addBranch("dev", { asset: asset });
python
import aws_cdk.aws_s3_assets as assets

# asset: assets.Asset
# amplify_app: amplify.App

branch = amplify_app.add_branch("dev", asset=asset)
java
import software.amazon.awscdk.services.s3.assets.*;

Asset asset;
App amplifyApp;

Branch branch = amplifyApp.addBranch("dev", BranchOptions.builder().asset(asset).build());
csharp
using Amazon.CDK.AWS.S3.Assets;

Asset asset;
App amplifyApp;

var branch = amplifyApp.AddBranch("dev", new BranchOptions { Asset = asset });
go
import assets "github.com/aws/aws-cdk-go/awscdk"

var asset Asset
var amplifyApp App

branch := amplifyApp.AddBranch(jsii.String("dev"), &BranchOptions{
	Asset: asset,
})

Skew protection for Amplify Deployments ​

Deployment skew protection is available to Amplify applications to eliminate version skew issues between client and servers in web applications. When you apply skew protection to an Amplify application, you can ensure that your clients always interact with the correct version of server-side assets, regardless of when a deployment occurs.

For more information, see Skew protection for Amplify deployments.

To enable skew protection, set the skewProtection property to true:

ts
declare const amplifyApp: amplify.App;
const branch = amplifyApp.addBranch("dev", { skewProtection: true });
python
# amplify_app: amplify.App

branch = amplify_app.add_branch("dev", skew_protection=True)
java
App amplifyApp;

Branch branch = amplifyApp.addBranch("dev", BranchOptions.builder().skewProtection(true).build());
csharp
App amplifyApp;

var branch = amplifyApp.AddBranch("dev", new BranchOptions { SkewProtection = true });
go
var amplifyApp App

branch := amplifyApp.AddBranch(jsii.String("dev"), &BranchOptions{
	SkewProtection: jsii.Boolean(true),
})
