As hinted in some of my recent articles on Rescript, I’ve been working on bindings to the wonderful Dexie interface to IndexedDB. It’s finally ready to announce to the world (in a fairly beta format)! rescript-dexie depends on a recent version of Rescript and the rescript-promise library. It’s still fairly beta and I haven’t covered all the features Dexie packs in yet, but the basics are working well. It feels intuitive and gives the right mix of sound type safety and easy call sites.
Introduction Most of my Rescript series so far has been about combining Rescript with React using create-react-app. Now that I understand Rescript better, I’m not so sure create-react-app is a good fit for it. Mostly because it’s slow. Rescript compiles JSX natively, so we shouldn’t need slow and hard-to-configure webpack. Most of create-react-app is about hiding the configuration of webpack from the end-user. I appreciate that. I’ve wasted more hours on webpack configuration than I care to count.
Introduction For basic syntax, functional programming does not feel that different from other paradigms. Sure, data and behaviour are separate, so you don’t have classes or objects or inheritance, but it feels relatively the same. This is especially true in Rescript, with the pipe-first syntax almost looking like a method lookup (comparable to the self object in Python). But if you go deeply into a study of functional languages, you start encountering bizarre words such as “monad” and “functor”.
Parsing dynamic content such as JSON in a statically typed language can be rather daunting. This article voices some opinions about schemaless design and migrates some of the messy json parsing code from the standard library to the excellent jzon library.
In a recent article I introduced rescript-zora, a library I wrote for unit testing Rescript code with lightning fast responses. One drawback of zora is that it’s very minimal. In this article, I explore some design principles and go on a bit of a rant about the definition of the word “unit”.
I wrote Rescript bindings to the zora test framework and wanted to write about how to actually use them.
