YAML snippets for AWS Serverless Application Model (SAM) resources, common Lambda configurations, parameters, conditions, and intrinsic functions in Visual Studio Code.
Tip
Catch AWS waste before and after you deploy.
CloudBurn is a free, open-source CLI that checks your Terraform and CloudFormation for costly patterns before deploy, then finds the waste already running in your AWS account. Run it locally or in CI.
Want it managed across your AWS accounts? CloudBurn Platform runs it for you and keeps scan results in your own account. Join the waitlist for 30% off.
- Adds support for the following SAM resource types:
AWS::Serverless::Api
AWS::Serverless::Application
AWS::Serverless::CapacityProvider
AWS::Serverless::Connector
AWS::Serverless::Function
AWS::Serverless::GraphQLApi
AWS::Serverless::HttpApi
AWS::Serverless::LayerVersion
AWS::Serverless::MicrovmImage
AWS::Serverless::NetworkConnector
AWS::Serverless::SimpleTable
AWS::Serverless::StateMachine
AWS::Serverless::WebSocketApi- Includes editable intrinsic functions and conditions, plus String, Number, CommaDelimitedList, and SSM parameter snippets.
- Adds short templates for ZIP functions, image functions, and HTTP API events.
- Generates full resource property scaffolds from a pinned AWS SAM schema, with documentation links and required-property annotations.
- Available on the Open VSX Registry for Gitpod support.
Open a .yaml or .yml file and select YAML as its language mode. Type a prefix and choose its completion, or press Ctrl+Space to open suggestions. Use Tab and Shift+Tab to move between placeholders.
| Prefix | Inserts | Placement |
|---|---|---|
sam or sam-template |
Minimal SAM template with an inline Lambda function | Empty file |
sam-function-zip |
Function using local source code | Resources |
sam-function-image |
Function using an ECR image | Resources |
sam-http-event |
HTTP API event | Function Events |
sam-parameter-string |
String parameter | Parameters |
sam-parameter-number |
Numeric parameter | Parameters |
sam-parameter-list |
Comma-delimited list parameter | Parameters |
sam-parameter-ssm |
SSM parameter reference | Parameters |
serverless-function or serverless-function-full |
Full Function property scaffold | Resources |
Other resource prefixes use the same pattern, such as serverless-api and serverless-connector. Existing resource, condition, and intrinsic prefixes are preserved; conditions and intrinsics also have sam- aliases.
Full property scaffolds include optional and alternative settings. Remove unused properties and fill in their values before deployment. For example, use the ZIP or image variant to avoid mixing CodeUri, InlineCode, and ImageUri. Snippets respect the editor's indentation settings.
sam-length, sam-to-json-string, and sam-for-each require AWS::LanguageExtensions. When combining it with SAM, list AWS::LanguageExtensions before AWS::Serverless-2016-10-31 in Transform. sam-get-stack-output inserts the long form of Fn::GetStackOutput for resource property values.
If you use AWS CloudFormation to manage your infrastructure as code, check out the CloudFormation Snippets VS Code extension. This extension provides comprehensive coverage, including snippets for:
- All AWS CloudFormation resources
- All AWS Serverless Application Model (SAM) resource types
The snippets support both YAML and JSON CloudFormation templates, streamlining your infrastructure development workflow.
Key features include:
- Autocomplete by simply typing the resource name (e.g.,
ec2-instance) - Intrinsic functions, conditions, and a wide variety of parameter types
- Placeholders for quick navigation within each resource
- Inline documentation links for each resource
- Automatic weekly updates with the latest CloudFormation Resource Specification
