AWS Lambda lifecycle and in-memory caching
The ephemeral nature of AWS Lambda functions might have you believe that techniques like in-memory caching cannot be utilized like you would with a conventional server, but that’s not the case! Let’s check out why. To understand this first you need to understand how the Lambda function lifecycle works. Suppose you had a function named “query”, the first time it’s invoked, AWS will fetch your zippe
Profiling Golang
There are plenty of guides for profiling Golang, just writing this here so I can find it again easily ☺ The runtime/pprof package offers lower level control over creating profiles, and the very cool net/http/pprof package registers HTTP end-points for profiling live applications, this is a really slick feature. To simplify things even further Dave Cheney created github.com/davecheney/profile, all
Docker builds for apex(1)
By default the apex Lambda function manager handles cross-compilation for Go programs, however that’s not always enough. When the function requires C bindings, or you’re deploying functions written in a language such a Rust without good cross-compilation support, you can defer to performing builds in Docker. Amazon provides a dockerhub image “amazonlinux” representing the OS that Lambda runs, so t
Minimizing boilerplate with NPM & Makefiles
I haven’t decided yet if I’m even going to open-source many of my components, primarily because of the pace of change they quickly become a burden. That said, I wanted to show an example of using Makefiles in NPM to help reduce the amount of boilerplate necessary for creating React components. Typically tasks like performing builds or starting development servers are defined in package.json as sho
Apex v0.6.0
Pretty small update this time, most of the work done was refactoring some internals, however we have some additional features as well! New Go runtimeThe Go runtime was previously in the apex/apex repository; we’ve moved it to https://github.com/apex/go-apex and added support for a number of source inputs: Arbitrary JSONCloudWatch LogsCognitoKinesisDynamoS3SNSSESNew Node.js runtimeNode.js runs nati
Introducing Apex
Apex is a small program written in Go for managing “serverless” architecture via AWS Lambda, allowing you to focus on code instead of infrastructure. I started Apex because I’ve been working on a number of product ideas as a solo engineer, I can’t afford to spend time managing and maintaining machines if I’m going to have a successful product as a single person team. I love Amazon’s Elastic Contai
