Kevin Wang's blog on anything from cloud architecture, to serverless tech, to Kettle® Chips. Recently, I'm into Golang, the AWS CDK, and MIT 6.824.

I like tinkering

Writing code is like playing with LEGO® pieces. Here's a fun project where the ripples mark where users of Bloc Stats have been.

I try to write things

Heavy emphasis on the try part.

Tree CLI & Benchmarks

(Re)creating a CLI tool to print directory contents in a tree-like format. And then some benchmarking.

Dynamic Matrices in GitHub Actions

...from JSON payloads that you send! — This was a recent rabbit hole 🐰🕳 that took me 2 days to figure out. I couldn't find a quick and clear answer on Google so I figured I'd write about it.

Micro Frontends in NextJS with Webpack 5

Webpack 5's Module Federation makes creating micro frontends straightforward. It is also available in NextJS 10+ via an experimental feature flag and it makes integrating micro frontends a breeze. You first build an external micro frontend and deploy it as a "federated module" to your destination of choice. Then you update some configs in your NextJS application and Webpack does the rest. It's kind of magic 🦄.

JAMStack CI/CD with Lerna, NextJS, CDK, and Github Actions

Lerna, AWS CDK, and Github Actions make continuous integration and continuous delivery super easy. I figured out how to setup a CI/CD pipeline for my NextJS static apps backed by additional AWS infrastructure like Lambda functions, API Gateway, and Dynamo DB.

Infrastructure as Code To Save Time

I found myself repeating some tedious tasks within the AWS console, week after week, and wanted to stop suffering. Infrasructure-as-code was the way to go but I knew I didn't want to learn Cloud Formation, and I was too lazy to pick up yet another 3rd party tool like Terraform.
