JavaScript is getting array grouping methods

Grouping items in an array is one of those things you’ve probably done a load of times. Each time you would have written a grouping function by hand or perhaps reached for lodash’s groupBy function.

Node.js includes built-in support for .env files

With the recent release of version 20.6.0, Node.js now has built-in support for .env files. You can now load environment variables from a .env file into process.env in your Node.js application completely dependency-free.

Easy and accessible pagination links for your Astro collections

Generating pagination links is not as straightforward as it may seem. So, while rebuilding my own site with Astro, I released a <Pagination /> component on npm as @philnash/astro-pagination that anyone can use in their Astro site. Read on to find out more.

Build bots on Bluesky with Node.js and GitHub Actions

Bluesky is the new social network in town and it’s an exciting place to explore right now. I was fortunate enough to get an invite early on and take part in the early community. But Bluesky is not just a Twitter clone, it’s an application on top of The AT Protocol, a (still being built) federated protocol for social networks with some interesting properties.

Create a CLI Chatbot with the ChatGPT API and Node.js

ChatGPT has taken the world by storm and this week OpenAI released the ChatGPT API. I’ve spent some time playing with ChatGPT in the browser, but the best way to really get on board with these new capabilities is to try building something with it. With the API available, now is that time.

Better two factor authentication experiences with WebOTP

Don't ever write your own function to parse URL parameters

Sometimes the platform we are building on provides more functionality than we can keep in our own heads. However, depending on the problem, we often find ourselves trying to write the code to solve the issue rather than finding and using the existing solution provided by the platform. I almost fell for this recently when trying to parse a query string.
