🎉 v2.13.0 shipped — Amazon Bedrock data source is here

[sid88in]

🚀 serverless-appsync-plugin v2.13.0

A new release is out — headlined by first-class Amazon Bedrock support (straight off the v2.12.0 roadmap), plus an important region-resolution fix and dependency hardening. Upgrade with:

npm install serverless-appsync-plugin@2.13.0
# or
npm install serverless-appsync-plugin@latest

✨ New features

• Amazon Bedrock runtime data source — a new AMAZON_BEDROCK_RUNTIME data source type lets resolvers invoke Bedrock foundation models directly from the APPSYNC_JS runtime using InvokeModel / Converse. Point a resolver at it and go:

  appSync:
    dataSources:
      bedrock:
        type: AMAZON_BEDROCK_RUNTIME
        config:
          models:
            - amazon.titan-text-lite-v1
            - eu.amazon.nova-2-lite-v1:0
            - arn:aws:bedrock:us-east-1:123456789012:inference-profile/us.anthropic.claude-3-5-haiku-20241022-v1:0

  • models scopes the auto-generated IAM policy. Bare foundation-model IDs, cross-region inference-profile IDs, and full ARNs / CloudFormation intrinsics are all supported. Inference-profile IDs (prefixed us., eu., apac., us-gov., global. — e.g. Amazon Nova) are automatically expanded into both the profile ARN and the underlying foundation-model ARN across the regions the profile can route to. Omit models and the generated role falls back to bedrock:InvokeModel / bedrock:Converse on *.
  • Also supports region (for ARN expansion; defaults to the stack region), serviceRoleArn (bring your own role), and iamRoleStatements (override the generated statements).
  • New runnable example: examples/datasource-bedrock, and full docs in doc/dataSources.md.

  ⚠️ Prerequisite: enable model access for each foundation model in the Amazon Bedrock console, in the same region as your API (and the regions an inference profile routes to). AppSync supports synchronous invocations only, completing within 10 seconds — streaming is not supported.

🐛 Fixes

• Region configured via variables now resolves correctly (#736) — fixes a regression from 2.11 where a region set through Serverless variables (e.g. region: ${opt:region, param:provider_region}) was captured as the literal unresolved string and rejected by the AWS SDK ("Region not accepted"). Region and credential resolution is now deferred until Serverless has resolved the configuration, so --region / --aws-profile CLI options, provider config, and assumed-role/env credentials are all honored.

🔧 Maintenance

• esbuild bumped 0.17 → 0.28 — a large jump for the bundler behind JS (APPSYNC_JS) resolvers. No config changes required; if you lean heavily on JS resolvers, a quick smoke-test of your bundles on upgrade is worthwhile.
• form-data security bump (4.0.5 → 4.0.6).

📝 Docs & examples

• Documented the Bedrock data source, including IAM scoping behavior and inference-profile handling.
• Added the datasource-bedrock example and a schemaVersion example entry.

🧪 Internal

• New Bedrock e2e test, unit tests, validation coverage, and snapshots.
