cloudsnorkel.cdk-turbo-layers 0.0.0

Speed-up Lambda function deployment with dependency layers built in AWS

Turbo Layers for CDK

Speed up deployment of Lambda functions by creating dependency layers in AWS instead of locally.

• Easily separate dependency deployment from Lambda code deployment
• Never re-package dependencies just because of a small code change
• Never download another single dependency package locally again
• Never upload oversized code packages again
• Edit your code in the browser -- no more "deployment package too large to enable inline code editing" errors
• Uninstall Docker from your laptop and extend your battery life
• Take shorter coffee breaks when deploying

Supported Lambda runtimes:

• Python
• Node.js
• Ruby

API

The best way to browse API documentation is on Constructs Hub. It is available in all supported programming languages.

Example

 const packager = new PythonDependencyPackager(this, 'Packager', {
    runtime: lambda.Runtime.PYTHON_3_9,
    type: DependencyPackagerType.LAMBDA,
});
new Function(this, 'Function with inline requirements', {
    handler: 'index.handler',
    code: lambda.Code.fromInline('def handler(event, context):\n  import requests'),
    runtime: lambda.Runtime.PYTHON_3_9,
    // this will create a layer from with requests and Scrapy in a Lambda function instead of locally
    layers: [packager.layerFromInline('inline requirements', ['requests', 'Scrapy'])],
});
new Function(this, 'Function with external source and requirements', {
    handler: 'index.handler',
    code: lambda.Code.fromAsset('lambda-src'),
    runtime: lambda.Runtime.PYTHON_3_9,
    // this will read pyproject.toml and poetry.lock and create a layer from the requirements in a Lambda function instead of locally
    layers: [packager.layerFromInline('poetry requirements', 'lambda-src')],
});
