AWS Lambda Layer

Creates a new public Lambda layer in each available AWS region and updates the Sentry release registry.

Configuration

Option	Description
`layerName`	Name of the Lambda layer. Supports template variables (see below)
`compatibleRuntimes`	List of runtime configurations
`compatibleArchitectures`	Optional list of instruction set architectures (`x86_64`, `arm64`)
`license`	Layer license
`linkPrereleases`	Publish layers for preview/pre-release versions. Default: `false`
`includeNames`	Must filter to exactly one artifact

Layer Name Templating

The layerName option supports Mustache-style template variables for dynamic version interpolation:

Variable	Description	Example (for v10.2.3)
`{{{version}}}`	Full version string	`10.2.3`
`{{{major}}}`	Major version number	`10`
`{{{minor}}}`	Minor version number	`2`
`{{{patch}}}`	Patch version number	`3`

This is useful when you want the layer name to reflect the SDK major version, making it easier for users to identify which version the layer supports.

Example: SentryNodeServerlessSDKv{{{major}}} becomes SentryNodeServerlessSDKv10 when publishing version 10.2.3.

Runtime Configuration

compatibleRuntimes:
  - name: node
    versions:
      - nodejs10.x
      - nodejs12.x
compatibleArchitectures:
  - x86_64
  - arm64

Environment Variables

Name	Description
`AWS_ACCESS_KEY`	AWS account access key
`AWS_SECRET_ACCESS_KEY`	AWS account secret key

Examples

Basic Example

targets:
  - name: aws-lambda-layer
    includeNames: /^sentry-node-serverless-\d+(\.\d+)*\.zip$/
    layerName: SentryNodeServerlessSDK
    compatibleRuntimes:
      - name: node
        versions:
          - nodejs22.x
          - nodejs24.x
    compatibleArchitectures:
      - x86_64
      - arm64
    license: MIT

With Version Templating

Include the major version in the layer name so users can easily identify SDK compatibility:

targets:
  - name: aws-lambda-layer
    includeNames: /^sentry-node-serverless-\d+(\.\d+)*\.zip$/
    layerName: SentryNodeServerlessSDKv{{{major}}}
    compatibleRuntimes:
      - name: node
        versions:
          - nodejs18.x
          - nodejs20.x
    license: MIT

When publishing version 10.2.3, the layer will be named SentryNodeServerlessSDKv10.
