How to Use Source Maps in TypeScript Lambda Functions (with Benchmarks)

• node-source-map-support

  1 2,147 0.0 JavaScript

  Adds source map support to node.js (for stack traces)

If we needed to enable Source Maps in a runtime that doesn't support the native version, we could always use Source Map Support.

• serverless-graphql

  216 2,708 0.0 JavaScript

  Serverless GraphQL Examples for AWS AppSync and Apollo

  

The Serverless Framework is known for its plugin system. serverless-esbuild brings bundling and all the options we need to support Source Maps in TypeScript into the sls package and sls deploy commands.

• SurveyJS

• sst

  179 20,277 9.8 TypeScript

  Build modern full-stack applications on AWS

  

Serverless Stack is a very cool value add that builds on top of AWS CDK delivering an awesome developer experience and dashboard. Unfortunately SST's own version of NodejsFunction, Function, doesn't support Source Maps or allow the passing of custom config options to esbuild. Hopefully this can be supported soon.

• aws-lambda-builders

  2 326 8.8 Python

  Python library to compile, build & package AWS Lambda functions for several runtimes & framework

  

SAM support for TypeScript has been lagging for some time, but a pull request was just merged that should change that. It looks like we'll be able to add an aws_sam key in the package.json file to enable building within the SAM engine as part of sam build. Although this PR has been merged to aws-lambda-builders, the engine behind sam build, it will still need to be added to aws-sam-cli and released (to much fanfare, one expects) before it can be used with SAM.

• esbuild

  325 37,351 9.5 Go

  An extremely fast bundler for the web

Emitting Source Maps is very easy with esbuild. We simply set the boolean property in our configuration. Now when we run the build, we'll get an index.js.map file as well as our index.js. This file must be uploaded to the Lambda service. We'll see how to do that with AWS CDK, AWS SAM and the Serverless Framework a bit later in this article.

• aws-sam-cli

  22 6,446 9.8 Python

  CLI tool to build, test, debug, and deploy Serverless applications using AWS SAM

• autocannon

  14 7,599 6.5 JavaScript

  fast HTTP/1.1 benchmarking tool written in Node.js

I used autocannon to test the function at 100 concurrent executions for 30 seconds. I also used Lambda Power Tuning to find the ideal memory configuration, which proved to be 512MB. All the results are available.

• aws-lambda-power-tuning

  36 5,175 8.7 JavaScript

  AWS Lambda Power Tuning is an open-source tool that can help you visualize and fine-tune the memory/power configuration of Lambda functions. It runs in your own AWS account - powered by AWS Step Functions - and it supports three optimization strategies: cost, speed, and balanced.
