Get Individual Contributor metrics from GitHub's GraphQL API

These are some handy snippets to get common metrics for checking how active a software engineer is.

• How many pushes are made by the IC?
• How many reviews are made by the IC?
• How many comments are made by the IC?

How to sort imports like a pro in TypeScript

Crossing reviews becomes a very common activity today in engineering behavior. To help us review changes for pull/merge requests easier, sorting imports can help us a much. The codebase becomes more professional and more consistent, reviewers will be happier, and the review process will be faster, focusing on the implementation changes ONLY.

Have you ever thought about how to sort imports in TypeScript projects automatically?

Let me show you how to archive sorting imports automatically in TypeScript projects with ESLint!

ES Modules are terrible, actually

This post was adapted from an earlier Twitter thread.

It's incredible how many collective developer hours have been wasted on pushing through the turd that is ES Modules (often mistakenly called "ES6 Modules"). Causing a big ecosystem divide and massive tooling support issues, for... well, no reason, really. There are no actual advantages to it. At all.

It looks shiny and new and some libraries use it in their documentation without any explanation, so people assume that it's the new thing that must be used. And then I end up having to explain to them why, unlike CommonJS, it doesn't actually work everywhere yet, and may never do so. For example, you can't import ESM modules from a CommonJS file! (Update: I've released a module that works around this issue.)

And then there's Rollup, which apparently requires ESM to be u

These are partial typings for the unexpected.js library and some of its dependencies and plugins.

No effort has been made to attempt to type the dynamic nature of the assertions, only the static interfaces have been attempted here

In this tutorial we're going to build a set of parser combinators.

What is a parser combinator?

We'll answer the above question in 2 steps.

1. What is a parser?
2. and, what is a parser combinator?

So first question: What is parser?

Why imperative imports are slower than declarative imports

A lot of people misunderstood Top-level await is a footgun, including me. I thought the primary danger was that people would be able to put things like AJAX requests in their top-level await expressions, and that this was terrible because await strongly encourages sequential operations even though a lot of the asynchronous activity we're talking about should actually happen concurrently.

But that's not the worst of it. Imperative module loading is intrinsically bad for app startup performance, in ways that are quite subtle.

Consider an app like this:

// main.js
