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

zod sugar

Creates a zod schema from a javascript value. Basically zod in reverse or zod backwards.

Built with Typescript for Node.js or the Browser.

import createZod from "zod-sugar";

const object = { foo: "bar", baz: 1 };
const schema = createZod(object);
// z.object({ foo: z.string(), bar: z.number() });
schema.safeParse(object).success // true

Installing

npm install zod-sugar
yarn add zod-sugar
pnpm install zod-sugar

Examples

createZod(null) // ZodNull

createZod(undefined) // ZodUndefined

createZod(1) // ZodNumber

createZod("foo") // ZodString

createZod(false) // ZodBoolean

createZod(Symbol("foo")) // ZodSymbol

createZod(BigInt(1)) // ZodBigInt

createZod([1, 2, 3]) // ZodArray

createZod({ foo: "bar", baz: 1 }) // ZodObject

createZod({
   string: "bar",
   number: 1,
   array: [1, 2, 3],
   bigint: BigInt(9007199254740991),
   object: {
      number: 0,
      boolean: false,
      object: {
         string: "bar",
         null: null,
         [Symbol("foo")]: "bar",
      },
      array: ["1", "2", "3"],
   },
   undefined: undefined,
}) // ZodObject

Caveats:

  1. While Zod itself attempts to mirror Typescript 1-1, this library only handles common Javascript values:
  • null
  • undefined
  • boolean
  • number
  • bigint
  • string
  • symbol
  • array
  • object

Support for more values coming soon:

  • date
  • set
  • map
  1. The schema returned is the most generic possible for obvious reasons - we can't infer beyond the values provided.

That's it!

Thanks for reading. I welcome your input, suggestions, feedback. Here is the medium article I wrote introducing this library.

Check out the following related libraries that I also built with this release.

ai-sugar AI Sugar is a collection of utility functions for working with AI apis.

const sorted = await ai.sort({
  array: ["green", "red", "blue", "yellow"],
  prompt: "rainbow color order",
});
// ["red", "yellow", "green", "blue"]

arrays-sugar Arrays Sugar is a set of array methods supporting async callbacks: everyAsync, filterAsync, findAsync, findIndexAsync, someAsync:

const array = [1, 2, 3];
array.findIndex(async (number) => number === 2) // 0 ❌
findIndex(array, async (number) => number === 2) // 1 ✅
