be-good: Simple and Flexible Data Decoders for TypeScript

This post is an introduction to both JSON decoders and my humble library of building blocks for them, called be-good.

Real-World Composable Error Handling in Reason

If you’ve ever considered handling errors in Reason or OCaml, chances are, you’ve happened upon Vladimir Keleshev’s article. Everybody links to it, so it seems like the way to handle errors. But how does it look in practice?

Type-And-Test Driven Development

I know what type-driven development is (didn’t say I’ve mastered it). I sort of get what is test-driven development, or even red-green-refactor. But can you do both at the same time? If you start with types, is there anything left of the green-red-refactor cycle? Or does that mean you write your tests post factum?

How Not to Introduce ReasonReact to Your Project

Well, actually the reality is not as harsh as the clickbaitey title would make you think. Nothing particularly wrong came out of my introduction of ReasonReact and, by extension, ReasonML to the static build of this very site. The claim that you can introduce Reason & ReasonReact to an existing application one component at a time is entirely true.

Tail-optimized functions in ReasonML

For that mechanism to work, you have to be sure you don’t do anything with the result of the recursive call other than return it as is. That way, you don’t have to return at all. The function instance that is called last evaluates the final result and returns it straight to the original callee.

TIL: Why ReasonML Has No Nullary Functions

“If you don’t provide all of a function’s parameters, you get a new function from the remaining parameters to the result. As a consequence, if you could actually provide no parameters at all, then func() would be the same as func and neither would actually call func.”

Chops v.0.0.0 Is Out

Well, no, my little watchful static build engine called Chops is not even actually out. It’s not published, it’s not documented, it’s not even a proper NPM module. I use it via npm link and that gives npm (or Yarn) a fit of recursion.

Look Ma, No Comments!

Ok, since this blog is experimental anyway, I’ve decided to experient some more and go without comments, at least for now. The first reason, to be honest, is I’ve played with Muut (don’t get me started on things like Disqus), aaand it’s somewhat hard. Much as I’m intrigued by Riot from the same authors, overriding a whole lot of Muut’s css rules is boring (and none of those!importants are particularly easy on these poor eyes).

Hello world

Hi y’all. If you read this, that means I’ve started my little developer’s blog that doubles as a project because none of those static site builders are any good I need to build something to learn JS and Node. And reading code is harder` than writing.
