The experimental +[`@aws-cdk/mixins-preview`](https://www.npmjs.com/package/@aws-cdk/mixins-preview) +package provides `MetadataContextMixin`, which attaches a context block +imperatively to exactly the constructs you target — via `.with()` on a +single L1 resource, or in bulk via `Mixins.of()`. Context applied by the +Mixin takes precedence over context cascaded from enclosing scopes. See the +`@aws-cdk/mixins-preview` README for usage. + +Template-level context holds cross-cutting facts stated once per stack: the +architecture overview, template-wide invariants, pointers to external shared +context, and ownership. The stack's purpose itself belongs in the native +CloudFormation `Description` (the `description` prop of `Stack`): + +```typescript +declare const stack: Stack; + +MetadataContext.of(stack).addToTemplate({ + arch: 'SQS buffer -> Lambda -> DynamoDB; DLQ for poison msgs', + must: ['all data encrypted w/ security-team CMK'], + refs: [ + { + at: 's3://org-iac-ctx/shared/encryption.ctx.yaml', + has: 'org CMK + tagging rules', + scope: 'shared', + }, + ], + owner: 'order-processing@example.com', +}); +``` + +Keep free-text values terse — drop articles and use symbols (`->`, `>=`, +`w/`) — since context competes with resources for the CloudFormation 1 MB +template size limit. Prefer `must` for binding rules whose violation breaks +something, and `why` for reasoning and rejected alternatives. + ## App Context [Context values](https://docs.aws.amazon.com/cdk/v2/guide/context.html) are key-value pairs that can be associated with an app, stack, or construct. diff --git a/packages/aws-cdk-lib/awslint.json b/packages/aws-cdk-lib/awslint.json index d7c43d49d83ce..cc15b3f436f33 100644 --- a/packages/aws-cdk-lib/awslint.json +++ b/packages/aws-cdk-lib/awslint.json @@ -10,6 +10,7 @@ "duration-prop-type:aws-cdk-lib.NestedStackProps.timeout", "docs-public-apis:aws-cdk-lib.Arn", "docs-public-apis:aws-cdk-lib.Aws.*", + "docs-public-apis:aws-cdk-lib.ContextTrustSource.*", "docs-public-apis:aws-cdk-lib.ContextProvider.getKey", "docs-public-apis:aws-cdk-lib.ContextProvider.getValue", "docs-public-apis:aws-cdk-lib.Reference.displayName", diff --git a/packages/aws-cdk-lib/core/lib/index.ts b/packages/aws-cdk-lib/core/lib/index.ts index b6863b5310dfb..d721c1e348187 100644 --- a/packages/aws-cdk-lib/core/lib/index.ts +++ b/packages/aws-cdk-lib/core/lib/index.ts @@ -1,5 +1,6 @@ export * from './aspect'; export * from './tag-aspect'; +export * from './metadata-context'; export * from './mixins'; diff --git a/packages/aws-cdk-lib/core/lib/metadata-context.ts b/packages/aws-cdk-lib/core/lib/metadata-context.ts new file mode 100644 index 0000000000000..e41e8ad19480f --- /dev/null +++ b/packages/aws-cdk-lib/core/lib/metadata-context.ts @@ -0,0 +1,552 @@ +import type { IConstruct } from 'constructs'; +import type { AspectOptions, IAspect } from './aspect'; +import { Aspects, AspectPriority } from './aspect'; +import { CfnResource } from './cfn-resource'; +import { + METADATA_CONTEXT_KEY, + RESOURCE_CONTEXT_METADATA_TYPE, + dedupe, + mergeResourceContext, + renderRef, + renderResourceContext, + validateResourceContext, + validateTemplateContext, +} from './private/metadata-context-internal'; +import { Stack } from './stack'; + +/** + * Change-safety level for a resource or an individual resource property. + * + * Part of the CloudFormation `Metadata.Context` v1 vocabulary.

9b48435e601f9f775dcef546be5a9b4850875994 Mon Sep 17 00:00:00 2001 From: Satyaki Ghosh Date: Thu, 23 Jul 2026 00:09:22 -0400 Subject: [PATCH 02/12] move MetadataContextMixin from @aws-cdk/mixins-preview into aws-cdk-lib core The mixins-preview package is being phased out and the feature is stable, so the Mixin ships directly in aws-cdk-lib alongside the MetadataContext facade (review feedback). - MetadataContextMixin now lives in core/lib/mixins/ and is exported flat from aws-cdk-lib (a top-level 'mixins' jsii submodule is not possible: JSII5011 name conflict with the Mixins class), with an awslint exclusion for the mixin-namespace rule. - Unit test moved to core/test/mixins/, adapted to core's toCloudFormation convention. - Integ test moved to @aws-cdk-testing/framework-integ test/core/test/ with regenerated snapshot. - aws-cdk-lib README documents the mixin inline; all mixins-preview changes reverted. ---

Plain grouping constructs, L3 patterns and +stacks are **not transparent** by default: context added on them does not leak +onto everything nested beneath. + +To fan out to descendants, opt in explicitly: ```typescript declare const stack: Stack; -declare const queue: sqs.Queue; -// Applies to every primary resource in the stack -MetadataContext.of(stack).add({ - must: ['all data encrypted w/ security-team CMK'], +// Cascade to the PRIMARY resource of every construct beneath the scope, +// treating grouping constructs / L3 patterns / stacks as transparent. +// The type filter keeps this per-resource hint on queues; helpers are skipped. +ResourceMetadataContext.of(stack).add({ + ops: 'drain queue before changing delivery settings', +}, { + applyToDescendants: true, + includeResourceTypes: ['AWS::SQS::Queue'], }); -// More specific context for one resource; inherits the stack-level `must` -MetadataContext.of(queue).add({ - why: 'buffers webhook events for async processing', +// Cascade to EVERY resource beneath the scope, helpers included. +ResourceMetadataContext.of(stack).add({ + deps: ['NetworkStack'], +}, { + applyToAllResources: true, }); ``` -Use the options to widen or narrow targeting: +Adding context on a `lambda.Function` targets the `AWS::Lambda::Function`, not +its execution role or log group.

Like `Tags`, descendant cascading crosses stack +boundaries, so context set on a scope containing a `NestedStack` also reaches +resources in the nested stack's template when descendants are enabled. + +Narrow targeting further with resource-type filters: -// Only apply to specific resource types -MetadataContext.of(stack).add({ +```typescript +declare const stack: Stack; + +ResourceMetadataContext.of(stack).add({ ops: 'drain queue before changing', }, { + applyToDescendants: true, includeResourceTypes: ['AWS::SQS::Queue'], }); ``` -Every resource context block records where it came from and how much to trust it. -When `trust` is omitted, CDK emits `source: AUTHORED` and defaults confidence to -`MEDIUM`.
