        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

compute_role (Optional[IRole]) – (experimental) The IAM role for an SSR app. The Compute role allows the Amplify Hosting compute service to securely access specific AWS resources based on the role’s permissions. Default: undefined - a new role is created when platform is Platform.WEB_COMPUTE or Platform.WEB_DYNAMIC, otherwise no compute role

Methods

add_auto_branch_environment(name, value)

(experimental) Adds an environment variable to the auto created branch.

All environment variables that you add are encrypted to prevent rogue access so you can use them to store secret information.

Parameters:

name (str)
value (str)

Stability:

experimental

Return type:

App

add_branch(id, *, asset=None, auto_build=None, basic_auth=None, branch_name=None, build_spec=None, compute_role=None, description=None, environment_variables=None, performance_mode=None, pull_request_environment_name=None, pull_request_preview=None, skew_protection=None, stage=None)

(experimental) Adds a branch to this application.

Parameters:

id (str)
asset (Optional[Asset]) – (experimental) Asset for deployment. The Amplify app must not have a sourceCodeProvider configured as this resource uses Amplify’s startDeployment API to initiate and deploy a S3 asset onto the App. Default: - no asset
auto_build (Optional[bool]) – (experimental) Whether to enable auto building for the branch. Default: true
basic_auth (Optional[BasicAuth]) – (experimental) The Basic Auth configuration. Use this to set password protection for the branch Default: - no password protection
branch_name (Optional[str]) – (experimental) The name of the branch. Default: - the construct’s id
build_spec (Optional[BuildSpec]) – (experimental) BuildSpec for the branch. Default: - no build spec
compute_role (Optional[IRole]) – (experimental) The IAM role to assign to a branch of an SSR app. The SSR Compute role allows the Amplify Hosting compute service to securely access specific AWS resources based on the role’s permissions. This role overrides the app-level compute role. Default: undefined - No specific role for the branch. If the app has a compute role, it will be inherited.
description (Optional[str]) – (experimental) A description for the branch. Default: - no description
environment_variables (Optional[Mapping[str, str]]) – (experimental) Environment variables for the branch. All environment variables that you add are encrypted to prevent rogue access so you can use them to store secret information. Default: - application environment variables
performance_mode (Optional[bool]) – (experimental) Enables performance mode for the branch. Performance mode optimizes for faster hosting performance by keeping content cached at the edge for a longer interval. When performance mode is enabled, hosting configuration or code changes can take up to 10 minutes to roll out. Default: false
pull_request_environment_name (Optional[str]) – (experimental) The dedicated backend environment for the pull request previews. Default: - automatically provision a temporary backend
pull_request_preview (Optional[bool]) – (experimental) Whether to enable pull request preview for the branch. Default: true
skew_protection (Optional[bool]) – (experimental) Specifies whether the skew protection feature is enabled for the branch. 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 a branch, you can ensure that your clients always interact with the correct version of server-side assets, regardless of when a deployment occurs. Default: None - Default setting is no skew protection.
stage (Optional[str]) – (experimental) Stage for the branch. Default: - no stage

apply_removal_policy(policy)

Apply the given removal policy to this resource.

The Removal Policy controls what happens to this resource when it stops being managed by CloudFormation, either because you’ve removed it from the CDK application or because you’ve made a change that requires the resource to be replaced.

The resource can be deleted (RemovalPolicy.DESTROY), or left in your AWS account for data recovery and cleanup later (RemovalPolicy.RETAIN).

Parameters:: policy (RemovalPolicy)
Return type:: None

to_string()

Returns a string representation of this construct.

Return type:: str

Attributes

PROPERTY_INJECTION_ID = '@aws-cdk.aws-amplify-alpha.App'

app_id

(experimental) The application id.

Stability:: experimental

app_name

(experimental) The name of the application.

Stability:: experimental
Attribute:: true

arn

(experimental) The ARN of the application.

Stability:: experimental
Attribute:: true

compute_role

(experimental) The IAM role for an SSR app.

Stability:: experimental

default_domain

(experimental) The default domain of the application.

Stability:: experimental
Attribute:: true

env

The environment this resource belongs to.

For resources that are created and managed by the CDK (generally, those created by creating new class instances like Role, Bucket, etc.), this is always the same as the environment of the stack they belong to; however, for imported resources (those obtained from static methods like fromRoleArn, fromBucketName, etc.), that might be different than the stack they were imported into.

grant_principal

(experimental) The principal to grant permissions to.

Stability:: experimental

node: The tree node.

platform

(experimental) The platform of the app.

Stability:: experimental

stack: The stack in which this resource is defined.

Static Methods

classmethod from_app_id(scope, id, app_id)

(experimental) Import an existing application.

Parameters:

scope (Construct)
id (str)
app_id (str)

Stability:

experimental

Return type:

IApp

classmethod is_construct(x)

Checks if x is a construct.

Use this method instead of instanceof to properly detect Construct instances, even when the construct library is symlinked.

Explanation: in JavaScript, multiple copies of the constructs library on disk are seen as independent, completely different libraries. As a consequence, the class Construct in each copy of the constructs library is seen as a different class, and an instance of one class will not test as instanceof the other class. npm install will not create installations like this, but users may manually symlink construct libraries together or use a monorepo tool: in those cases, multiple copies of the constructs library can be accidentally installed, and instanceof will behave unpredictably. It is safest to avoid using instanceof, and using this type-testing method instead.

Parameters:: x (Any) – Any object.
Return type:: bool
Returns:: true if x is an object created from a class which extends Construct.

classmethod is_owned_resource(construct)

Returns true if the construct was created by CDK, and false otherwise.

Parameters:: construct (IConstruct)
Return type:: bool

classmethod is_resource(construct)

Check whether the given construct is a Resource.

Parameters:: construct (IConstruct)
Return type:: bool
