diataxis-documentation-framework VS zod

Perhaps it could be restructured to separate out the howto from the explanation to serve the reader’s intended use at the time as described here: https://diataxis.fr

Create an organized repository for regularly updated documentation, making it easy to access important information.

Such integration capabilities really help push the developer productivity, whether that's in single-project workspaces or monorepos. Juri also dives deeper into efforts from the team to provide high quality educational content around Nx and its capabilities. The Nx docs have been restructured to follow the Diataxisframework, dividing content into into learning-, task-, understanding- and information-oriented sections.

I think people may be missing the core point of this article.

Anton has built a new thing, https://codapi.org/ - which provides a web component that makes it easy to embed interactive code snippets for HTTP APIs, Python code and more directly in pages of documentation.

This article demonstrates this new technology in the context of the https://diataxis.fr/ documentation framework, which recommends going beyond just straight API reference documentation and ensuring you cover tutorials, how-to guides and explanations as well.

I think this is really cool.

As much as possible on all facets, because that is what "documentation" means, and if you are a product manager who wasn't paying attention in product management 101 and need some guidance on what "documentation" is, try reading this first.

"The Diátaxis framework aims to solve the problem of structure in technical documentation. It adopts a systematic approach to understanding the needs of documentation users in their cycle of interaction with a product.

Diátaxis identifies four modes of documentation - tutorials, how-to guides, technical reference and explanation. It derives its structure from the relationship between them.(...)"

mostly the same but some additional information for people who are interested

This is a very fair comment, and you seem open to understanding why types are useful.

"problems that are due to typing" is a very difficult thing to unpack because types can mean _so_ many things.

Static types are absolutely useless (and, really, a net negative) if you're not using them well.

Types don't help if you don't spend the time modeling with the type system. You can use the type system to your advantage to prevent invalid states from being represented _at all_.

As an example, consider a music player that keeps track of the current song and the current position in the song.

If you model this naively you might do something like: https://gist.github.com/shepherdjerred/d0f57c99bfd69cf9eada4...

In the example above you _are_ using types. It might not be obvious that some of these issues can be solved with stronger types, that is, you might say that "You rarely see problems that are due to typing".

Here's an example where the type system can give you a lot more safety: https://gist.github.com/shepherdjerred/0976bc9d86f0a19a75757...

You'll notice that this kind of safety is pretty limited. If you're going to write a music app, you'll probably need API calls, local storage, URL routes, etc.

TypeScript's typechecking ends at the "boundaries" of the type system, e.g. it cannot automatically typecheck your fetch or localStorage calls return the correct types. If you're casting, you're bypassing the type systems and making it worthless. Runtime type checking libraries like Zod [0] can take care of this for you and are able to typecheck at the boundaries of your app so that the type system can work _extremely_ well.

[0]: https://zod.dev/ note: I mentioned Zod because I like it. There are _many_ similar libraries.

Zod is an open-source schema declaration and validation library that emphasizes TypeScript. It can refer to any data type, from simple to complex. Zod eliminates duplicative type declarations by inferring static TypeScript types and allows easy composition of complex data structures from simpler ones. It has no dependencies, is compatible with Node.js and modern browsers, and has a concise, chainable interface. Zod is lightweight (8kb when zipped), immutable, with methods returning new instances. It encourages parsing over validation and is not limited to TypeScript but works well with JavaScript as well.

Zod is a TypeScript-first schema declaration and validation library. It helps create schemas for any data type and is very developer-friendly. Zod has the functional approach of "parse, don't validate." It supports coercion in all primitive types.

You can check out their documentation here.

You can learn more about Zod on their website here.

In JS, it's a good idea anyway to use some JSON parsing library instead of JSON.parse.

With Zod, you can use z.bigint() parser. If you take the "parse any JSON" snippet https://zod.dev/?id=json-type and change z.number() to z.bigint(), it should do what you are looking for.

We will validate our input using client-side zod. Zod handles TypeScript-first schema validation with static type inference. This means that it will not only validate your fields, it will also set types on validated fields.
