aws-cdk.aws-amplify 1.32.2

The CDK Construct Library for AWS::Amplify

AWS Amplify Construct Library

---

This is a developer preview (public beta) module.

All classes with the Cfn prefix in this module (CFN Resources) are auto-generated from CloudFormation. They are stable and safe to use.

However, all other classes, i.e., higher level constructs, are under active development and subject to non-backward compatible changes or removal in any future version. These are not subject to the Semantic Versioning model. This means that while you may use them, you may need to update your source code when upgrading to a newer version of this package.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:

# Example automatically generated without compilation. See https://github.com/aws/jsii/issues/826
import aws_cdk.aws_codebuild as codebuild
import aws_cdk.aws_amplify as amplify
import aws_cdk.core as cdk

amplify_app = amplify.App(self, "MyApp",
    source_code_provider=amplify.GitHubSourceCodeProvider(
        owner="<user>",
        repository="<repo>",
        oauth_token=cdk.SecretValue.secrets_manager("my-github-token")
    ),
    build_spec=codebuild.BuildSpec.from_object({# Alternatively add a `amplify.yml` to the repo
        "version": "1.0",
        "frontend": {
            "phases": {
                "pre_build": {
                    "commands": ["yarn"
                    ]
                },
                "build": {
                    "commands": ["yarn build"
                    ]
                }
            },
            "artifacts": {
                "base_directory": "public",
                "files": "**/*"
            }
        }})
)

To connect your App to CodeCommit, use the CodeCommitSourceCodeProvider:

# Example automatically generated without compilation. See https://github.com/aws/jsii/issues/826
repository = codecommit.Repository(self, "Repo",
    repository_name="my-repo"
)

amplify_app = amplify.App(self, "App",
    source_code_provider=amplify.CodeCommitSourceCodeProvider(repository=repository)
)

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

Add branches:

# Example automatically generated without compilation. See https://github.com/aws/jsii/issues/826
master = amplify_app.add_branch("master")# `id` will be used as repo branch name
dev = amplify_app.add_branch("dev")
dev.add_environment("STAGE", "dev")

Auto build and pull request preview are enabled by default.

Add custom rules for redirection:

# Example automatically generated without compilation. See https://github.com/aws/jsii/issues/826
amplify_app.add_custom_rule(
    source="/docs/specific-filename.html",
    target="/documents/different-filename.html",
    status=amplify.RedirectStatus.TEMPORARY_REDIRECT
)

Add a domain and map sub domains to branches:

# Example automatically generated without compilation. See https://github.com/aws/jsii/issues/826
domain = amplify_app.add_domain("example.com")
domain.map_sub_domain(master, "www")
domain.map_sub_domain(dev)

Restricting access

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

Use BasicAuth.fromCredentials when referencing an existing secret:

# Example automatically generated without compilation. See https://github.com/aws/jsii/issues/826
amplify_app = amplify.App(self, "MyApp",
    repository="https://github.com/<user>/<repo>",
    oauth_token=cdk.SecretValue.secrets_manager("my-github-token"),
    basic_auth=amplify.BasicAuth.from_credentials("username", cdk.SecretValue.secrets_manager("my-github-token"))
)

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

# Example automatically generated without compilation. See https://github.com/aws/jsii/issues/826
amplify_app = amplify.App(self, "MyApp",
    repository="https://github.com/<user>/<repo>",
    oauth_token=cdk.SecretValue.secrets_manager("my-github-token"),
    basic_auth=amplify.BasicAuth.from_generated_password("username")
)

Basic auth can be added to specific branches:

# Example automatically generated without compilation. See https://github.com/aws/jsii/issues/826
app.add_branch("feature/next",
    basic_auth=amplify.BasicAuth.from_generated_password("username")
)

Automatically creating branches

Use the autoBranchCreation prop to automatically create new branches:

# Example automatically generated without compilation. See https://github.com/aws/jsii/issues/826
amplify_app = amplify.App(self, "MyApp",
    repository="https://github.com/<user>/<repo>",
    oauth_token=cdk.SecretValue.secrets_manager("my-github-token"),
    auto_branch_creation={
        "patterns": ["feature/*", "test/*"]
    }
)
