  • serverless-express

    Run Node.js web applications and APIs using existing application frameworks on AWS #serverless technologies such as Lambda, API Gateway, [email protected], and ALB.

    Project mention: Porting Curveball to Bun | | 2022-09-13

    To get Express to run on AWS Lambda the Node http stack needs to be emulated, or a full-blown HTTP/TCP server needs to be started and proxied to. Each of these workarounds require a ton of code from libraries like serverless-express.

  • aws-lambda-power-tuning

    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.

    Project mention: AWS Serverless Production Readiness Checklist | | 2023-01-21

    Project mention: Call to help beta test wireless highlight backups with | | 2022-07-22

    Thanks for taking a look! I use the for OAuth (to spare people having to remember yet another password) and I believe it uses cookies to prevent OAuth replay attacks. Thanks for highlighting this. I'll work on a better error message if cookies are not enabled.

  • middy

    🛵 The stylish Node.js middleware engine for AWS Lambda 🛵

    Project mention: Ask HN: What would be your stack if you are building an MVP today? | | 2023-01-26

    I mean I'm literally building an AWS lambda function that outputs HTML when it's called via API Gateway. So someone hits, then the MyCoolPage AWS Lambda function is executed and outputs whatever.

    If you're interested, I use as a middleware engine for my AWS lambda functions which I find helpful.

    I use the open sourced serverless framework for doing deploys

    Project mention: Keeping Functions Warm — How To Fix AWS Lambda Cold Start Issues | | 2022-03-24

  • serverless-appsync-plugin

    serverless plugin for appsync

    Project mention: Building a chat application using AWS AppSync and Serverless | | 2022-04-21

  • lambda-local

    Commandline tool to run Amazon Lambda function on local machines.

  • serverless-bundle

    Project mention: Migrating a classic Express.js to Serverless Framework | | 2022-04-20

    As you can see in the above handler.js file, we're getting CommonJS instead of modern JavaScript or TypeScript. To get these, you need webpack or some other bundler. serverless-webpack exists if you want full control over your ecosystem, but there is also serverless-bundle that gives you a set of reasonable defaults on webpack 4 out of the box. We opted into this option to get us started quickly.
