Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Readme

Astro Content Collections Zod to JSON Schemas

Installation

npm install astro-zod-to-json-schema

Configure Content Collections:

import { defineCollection, z } from 'astro:content';
+ import { astroZodCollectionsToJsonSchemas } from 'astro-zod-to-json-schema';

const blog = defineCollection({
	// Type-check frontmatter using a schema
	schema: z.object({
		title: z.string(),
		description: z.string(),
		// Transform string to Date object
		pubDate: z.coerce.date(),
		updatedDate: z.coerce.date().optional(),
		heroImage: z.string().optional(),
	}),
});

export const collections = { blog };

+ await astroZodCollectionsToJsonSchemas(collections);

Everytime you edit /src/content/config.ts file while using astro dev, each collection schemas will be automatically emitted, alongside Astro's own typings generation process:

.
├── ...
├── src
│   ├── content
│   │   ├── blog
+   │   │   ├── _blog.schema.json
│   │   │   ├── first-post.md
│   │   │   ├── second-post.md
│   │   │   ├── third-post.md
│   │   │   └── ...
│   │   └── config.ts
└── ...

18 directories, 35 files

Note the underscore, so it's ignored by Content Collection loader (analogously to the pages folder).
You can still import them as regular JSON files into your project though!
For example if you need to use them for OpenAPI, AJV, or anytime you need a serialized version of your Zod schemas, really.

That's all folks!


Now that you have those sweet serialized schemas, you can leverage the immense JSON schemas eco-system (see below).

Use cases

Lint / validate your Markdown frontmatter

Demo screenshot of frontmatter schema linter 1

Install remark + plugins:

npm install -D \
  remark remark-cli \
  remark-frontmatter \
  remark-lint-frontmatter-schema

Create the remark config:

# ./demo/.remarkrc.yaml

plugins:
  - remark-frontmatter

  - - remark-lint-frontmatter-schema
    - schemas:
        src/content/blog/_blog.schema.json:
          - src/content/blog/*.{md,mdx}

Note
You can also put it in ./demo/src/content/.remarkrc.yaml.
remark-lint-frontmatter-schema will resolve relative paths accordingly from where it's placed (e.g blog/_blog.schema.json).

See the remark-lint-frontmatter-schema full documentation.

Auto-generating forms UIs

See the JSON Schema Form Element library.

Uses with OpenAPI

See the Astro OpenAPI library.

Future maintenance concerns

Note that those concerns only affect developer maintenance, not really the end user.

SchemaContext is subject to changes. This library is stubbing it.
Typings are not implemented (lacking some comprehension / affordance of Astro's own internal / public APIs for now).
Also some of the magic is happening in user-land (codegen, Vite virtual modules, etc.), making things a bit more hazardous.
See notes in code comments.
