Awesome

This component is responsible for provisioning:

S3 bucket
CloudFront distribution for a Single Page Application
ACM placed in us-east-1 regardless of the stack region (requirement of CloudFront)

NOTE: The component does not use the ACM created by dns-delegated, because the ACM region has to be us-east-1.

Usage

Stack Level: Regional

Here are some example snippets for how to use this component:

An import for all instantiations of the spa-s3-cloudfront component can be created at stacks/spa/spa-defaults.yaml:

components:
  terraform:
    spa-s3-cloudfront:
      vars:
        # lookup GitHub Runner IAM role via remote state
        github_runners_deployment_principal_arn_enabled: true
        github_runners_component_name: github-runners
        github_runners_tenant_name: core
        github_runners_environment_name: ue2
        github_runners_stage_name: auto
        origin_force_destroy: false
        origin_versioning_enabled: true
        origin_block_public_acls: true
        origin_block_public_policy: true
        origin_ignore_public_acls: true
        origin_restrict_public_buckets: true
        origin_encryption_enabled: true
        cloudfront_index_document: index.html
        cloudfront_ipv6_enabled: false
        cloudfront_compress: true
        cloudfront_default_root_object: index.html
        cloudfront_viewer_protocol_policy: redirect-to-https

An import for all instantiations for a specific SPA can be created at stacks/spa/example-spa.yaml:

components:
  terraform:
    example-spa:
      component: spa-s3-cloudfront
      vars:
        name: example-spa
        site_subdomain: example-spa
        cloudfront_allowed_methods:
          - GET
          - HEAD
        cloudfront_cached_methods:
          - GET
          - HEAD
        cloudfront_custom_error_response:
          - error_caching_min_ttl: 1
            error_code: 403
            response_code: 200
            response_page_path: /index.html
        cloudfront_default_ttl: 60
        cloudfront_min_ttl: 60
        cloudfront_max_ttl: 60

Finally, the spa-s3-cloudfront component can be instantiated in a stack config:

import:
  - spa/example-spa

components:
  terraform:
    example-spa:
      component: spa-s3-cloudfront
      settings:
        spacelift:
          workspace_enabled: true
      vars: {}

Failover Origins

Failover origins are supported via var.failover_s3_origin_name and var.failover_s3_origin_region.

Preview Environments

SPA Preview environments (i.e. subdomain.example.com mapping to a /subdomain path in the S3 bucket) powered by Lambda@Edge are supported via var.preview_environment_enabled. See the both the variable description and inline documentation for an extensive explanation for how these preview environments work.

Customizing Lambda@Edge

This component supports customizing Lambda@Edge functions for the CloudFront distribution. All Lambda@Edge function configuration is deep merged before being passed to the cloudposse/cloudfront-s3-cdn/aws//modules/lambda@edge module. You can add additional functions and overwrite existing functions as such:

import:
  - catalog/spa-s3-cloudfront/defaults

components:
  terraform:
    refarch-docs-site-spa:
      metadata:
        component: spa-s3-cloudfront
        inherits:
          - spa-s3-cloudfront-defaults
      vars:
        enabled: true
        lambda_edge_functions:
          viewer_request: # overwrite existing function
            source: null # this overwrites the 404 viewer request source with deep merging
            source_zip: "./dist/lambda_edge_paywall_viewer_request.zip"
            runtime: "nodejs16.x"
            handler: "index.handler"
            event_type: "viewer-request"
            include_body: false
          viewer_response: # new function
            source_zip: "./dist/lambda_edge_paywall_viewer_response.zip"
            runtime: "nodejs16.x"
            handler: "index.handler"
            event_type: "viewer-response"
            include_body: false
