The Amazon Resource Name (ARN) of the IAM role to assign to a branch of an SSR app.
notes

The SSR Compute role allows the Amplify Hosting compute service to securely access specific AWS resources based on the role's permissions. For more information about the SSR Compute role, see Adding an SSR Compute role in the Amplify User Guide .

descriptionoptionalstringdescriptionoptionalstrdescriptionoptionalStringDescriptionoptionalstringDescriptionoptional*string#
The description for the branch that is part of an Amplify app.
enableAutoBuildoptionalboolean | IResolvableenable_auto_buildoptionaltyping.Union[bool, IResolvable]enableAutoBuildoptionalBooleanEnableAutoBuildoptionalboolEnableAutoBuildoptionalinterface{}#

enablePerformanceModeoptionalboolean | IResolvableenable_performance_modeoptionaltyping.Union[bool, IResolvable]enablePerformanceModeoptionalBooleanEnablePerformanceModeoptionalboolEnablePerformanceModeoptionalinterface{}#
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.

enablePullRequestPreviewoptionalboolean | IResolvableenable_pull_request_previewoptionaltyping.Union[bool, IResolvable]enablePullRequestPreviewoptionalBooleanEnablePullRequestPreviewoptionalboolEnablePullRequestPreviewoptionalinterface{}#
Specifies whether Amplify Hosting creates a preview for each pull request that is made for this branch.
notes

If this property is enabled, Amplify deploys your app to a unique preview URL after each pull request is opened. Development and QA teams can use this preview to test the pull request before it's merged into a production or integration branch.

To provide backend support for your preview, Amplify automatically provisions a temporary backend environment that it deletes when the pull request is closed. If you want to specify a dedicated backend environment for your previews, use the PullRequestEnvironmentName property.

For more information, see Web Previews in the AWS Amplify Hosting User Guide .

enableSkewProtectionoptionalboolean | IResolvableenable_skew_protectionoptionaltyping.Union[bool, IResolvable]enableSkewProtectionoptionalBooleanEnableSkewProtectionoptionalboolEnableSkewProtectionoptionalinterface{}#
Specifies whether the skew protection feature is enabled for the branch.
notes

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. For more information about skew protection, see Skew protection for Amplify deployments in the Amplify User Guide .

If pull request previews are enabled for this branch, you can use this property to specify a dedicated backend environment for your previews.
notes

For example, you could specify an environment named prod , test , or dev that you initialized with the Amplify CLI and mapped to this branch.

To enable pull request previews, set the EnablePullRequestPreview property to true .

If you don't specify an environment, Amplify Hosting provides backend support for each preview by automatically provisioning a temporary backend environment. Amplify Hosting deletes this environment when the pull request is closed.

For more information about creating backend environments, see Feature Branch Deployments and Team Workflows in the AWS Amplify Hosting User Guide .

Methods ​

addDeletionOverride(path: string): voiddef add_deletion_override(self, path: str) -> Nonepublic void addDeletionOverride(String path)public void AddDeletionOverride(string path)func AddDeletionOverride(Path *string)#
Syntactic sugar for `addOverride(path, undefined)`.
1 parameter

Parameters

  • pathpathpathpathPath — The path of the value to delete.
addDependency(target: CfnResource): voiddef add_dependency(self, target: CfnResource) -> Nonepublic void addDependency(CfnResource target)public void AddDependency(CfnResource target)func AddDependency(Target CfnResource)deprecated#
Use `addResourceDependency` instead.

This method has been renamed to addResourceDependency to more clearly set it apart from construct.node.addDependency. See the documentation of that function for more details.

addDependsOn(target: CfnResource): voiddef add_depends_on(self, target: CfnResource) -> Nonepublic void addDependsOn(CfnResource target)public void AddDependsOn(CfnResource target)func AddDependsOn(Target CfnResource)deprecated#
Use `addResourceDependency` instead.
notes

This can be used for resources across stacks (or nested stack) boundaries and the dependency will automatically be transferred to the relevant scope.

This method has been renamed to addResourceDependency, which makes it more clear that this method operates at a different level from the construct-level construct.node.addDependency() mechanism.

addMetadata(key: string, value: any): voiddef add_metadata(self, key: str, value: Any) -> Nonepublic void addMetadata(String key, Object value)public void AddMetadata(string key, object value)func AddMetadata(Key *string, Value interface{})#
Add a value to the CloudFormation Resource Metadata.
addOverride(path: string, value: any): voiddef add_override(self, path: str, value: Any) -> Nonepublic void addOverride(String path, Object value)public void AddOverride(string path, object value)func AddOverride(Path *string, Value interface{})#
Adds an override to the synthesized CloudFormation resource.
notes · 2 parameters

To add a property override, either use addPropertyOverride or prefix path with "Properties." (i.e. Properties.TopicName).

If the override is nested, separate each nested level using a dot (.) in the path parameter. If there is an array as part of the nesting, specify the index in the path.

To include a literal . in the property name, prefix with a \. In most programming languages you will need to write this as "\\." because the \ itself will need to be escaped.

For example,

typescript
cfnResource.addOverride('Properties.GlobalSecondaryIndexes.0.Projection.NonKeyAttributes', ['myattribute']);
cfnResource.addOverride('Properties.GlobalSecondaryIndexes.1.ProjectionType', 'INCLUDE');

would add the overrides

json
"Properties": {
  "GlobalSecondaryIndexes": [
    {
      "Projection": {
        "NonKeyAttributes": [ "myattribute" ]
        ...
      }
      ...
    },
    {
      "ProjectionType": "INCLUDE"
      ...
    },
  ]
  ...
}

The value argument to addOverride will not be processed or translated in any way. Pass raw JSON values in here with the correct capitalization for CloudFormation. If you pass CDK classes or structs, they will be rendered with lowercased key names, and CloudFormation will reject the template.

Parameters

  • pathpathpathpathPath — - The path of the property, you can use dot notation to override values in complex types.
  • valuevaluevaluevalueValue — - The value.
addPropertyDeletionOverride(propertyPath: string): voiddef add_property_deletion_override(self, property_path: str) -> Nonepublic void addPropertyDeletionOverride(String propertyPath)public void AddPropertyDeletionOverride(string propertyPath)func AddPropertyDeletionOverride(PropertyPath *string)#
Adds an override that deletes the value of a property from the resource definition.
1 parameter

Parameters

  • propertyPathproperty_pathpropertyPathpropertyPathPropertyPath — The path to the property.
addPropertyOverride(propertyPath: string, value: any): voiddef add_property_override(self, property_path: str, value: Any) -> Nonepublic void addPropertyOverride(String propertyPath, Object value)public void AddPropertyOverride(string propertyPath, object value)func AddPropertyOverride(PropertyPath *string, Value interface{})#
Adds an override to a resource property.

Syntactic sugar for addOverride("Properties.<...>", value).

2 parameters

Parameters

  • propertyPathproperty_pathpropertyPathpropertyPathPropertyPath — The path of the property.
  • valuevaluevaluevalueValue — The value.
addResourceDependency(target: CfnResource, reason?: string): voiddef add_resource_dependency(self, target: CfnResource, reason: typing.Optional[str] = None) -> Nonepublic void addResourceDependency(CfnResource target, String reason)public void AddResourceDependency(CfnResource target, string? reason = null)func AddResourceDependency(Target CfnResource, Reason *string)#
Indicates that this resource depends on another resource and cannot be provisioned unless the other resource has been successfully provisioned.
notes

This can be used for resources across stacks (or nested stack) boundaries and the dependency will automatically be transferred to the relevant scope.

This method only adds dependencies between L1 resources. If you are looking for a generic construct-to-construct dependency mechanism that works for all constructs including L2s, use construct.node.addDependency instead.

applyCrossStackReferenceStrength(strength: ReferenceStrength): voiddef apply_cross_stack_reference_strength(self, strength: ReferenceStrength) -> Nonepublic void applyCrossStackReferenceStrength(ReferenceStrength strength)public void ApplyCrossStackReferenceStrength(ReferenceStrength strength)func ApplyCrossStackReferenceStrength(Strength ReferenceStrength)#
Sets the cross-stack reference strength for this resource.

When set, any cross-stack reference to this resource will use the specified strength instead of the global default from the consuming stack's context.

1 parameter

Parameters

  • strengthstrengthstrengthstrengthStrength — - The reference strength to use for this resource.
applyRemovalPolicy(policy?: RemovalPolicy, options?: RemovalPolicyOptions): voiddef apply_removal_policy(self, policy: typing.Optional[RemovalPolicy] = None, options: typing.Optional[RemovalPolicyOptions] = None) -> Nonepublic void applyRemovalPolicy(RemovalPolicy policy, RemovalPolicyOptions options)public void ApplyRemovalPolicy(RemovalPolicy? policy = null, RemovalPolicyOptions? options = null)func ApplyRemovalPolicy(Policy RemovalPolicy, Options RemovalPolicyOptions)#
Sets the deletion policy of the resource based on the removal policy specified.
notes

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). In some cases, a snapshot can be taken of the resource prior to deletion (RemovalPolicy.SNAPSHOT). A list of resources that support this policy can be found in the following link:

isCfnBranch(x: any): boolean@staticmethod def is_cfn_branch(x: Any) -> boolpublic static Boolean isCfnBranch(Object x)public static bool IsCfnBranch(object x)func IsCfnBranch(X interface{}) *boolstatic#

isCfnElement(x: any): boolean@staticmethod def is_cfn_element(x: Any) -> boolpublic static Boolean isCfnElement(Object x)public static bool IsCfnElement(object x)func IsCfnElement(X interface{}) *boolstatic#
Returns `true` if a construct is a stack element (i.e. part of the synthesized cloudformation template).

Uses duck-typing instead of instanceof to allow stack elements from different versions of this library to be included in the same stack.

returns

Returns: The construct as a stack element or undefined if it is not a stack element.

isCfnResource(x: any): boolean@staticmethod def is_cfn_resource(x: Any) -> boolpublic static Boolean isCfnResource(Object x)public static bool IsCfnResource(object x)func IsCfnResource(X interface{}) *boolstatic#
Check whether the given object is a CfnResource.
isConstruct(x: any): boolean@staticmethod def is_construct(x: Any) -> boolpublic static Boolean isConstruct(Object x)public static bool IsConstruct(object x)func IsConstruct(X interface{}) *boolstatic#
Checks if `x` is a construct.
notes · 1 parameter · returns

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

  • xxxxX — Any object.

Returns: true if x is an object created from a class which extends Construct.

Retrieves an array of resources and stacks this resource depends on.

For resources depended on directly, returns the CfnResource object. For dependencies on other stacks, returns the Stack object. The order of the array is not guaranteed.

overrideLogicalId(newLogicalId: string): voiddef override_logical_id(self, new_logical_id: str) -> Nonepublic void overrideLogicalId(String newLogicalId)public void OverrideLogicalId(string newLogicalId)func OverrideLogicalId(NewLogicalId *string)#
Overrides the auto-generated logical ID with a specific ID.
1 parameter

Parameters

  • newLogicalIdnew_logical_idnewLogicalIdnewLogicalIdNewLogicalId — The new logical ID to use for this stack element.
removeDependency(target: CfnResource): voiddef remove_dependency(self, target: CfnResource) -> Nonepublic void removeDependency(CfnResource target)public void RemoveDependency(CfnResource target)func RemoveDependency(Target CfnResource)deprecated#
Use `removeResourceDependency` instead

This can be used for resources across stacks (including nested stacks) and the dependency will automatically be removed from the relevant scope.

removeResourceDependency(target: CfnResource): voiddef remove_resource_dependency(self, target: CfnResource) -> Nonepublic void removeResourceDependency(CfnResource target)public void RemoveResourceDependency(CfnResource target)func RemoveResourceDependency(Target CfnResource)#
Indicates that this resource no longer depends on another resource.

This can be used for resources across stacks (including nested stacks) and the dependency will automatically be removed from the relevant scope.

replaceDependency(target: CfnResource, newTarget: CfnResource): voiddef replace_dependency(self, target: CfnResource, new_target: CfnResource) -> Nonepublic void replaceDependency(CfnResource target, CfnResource newTarget)public void ReplaceDependency(CfnResource target, CfnResource newTarget)func ReplaceDependency(Target CfnResource, NewTarget CfnResource)#
Replaces one dependency with another.

returns

Returns: a string representation of this resource

with(...mixins: IMixin[]): IConstructdef with(self, mixins: IMixin) -> IConstructpublic IConstruct with(IMixin mixins)public IConstruct With(IMixin mixins)func With(Mixins IMixin) IConstruct#
Applies one or more mixins to this construct.

Mixins are applied in order. The list of constructs is captured at the start of the call, so constructs added by a mixin will not be visited. Use multiple with() calls if subsequent mixins should apply to added constructs.
