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

vite-plugin-doctest

Vitest plugin for doctest. You can write test in your source code with documentation.

Usage

/**
 * @example
 * ```ts @import.meta.vitest
 * expect(add(1, 2)).toBe(3);
 * assert(add(3, 4) === 7);
 * ```
 */
export function add(a: number, b: number) {
  return a + b;
}

You can also test code in markdown.

# Test

```ts:[email protected]
const { add } = await import('./add');
expect(add(1, 2)).toBe(3);
```

Setup

npm i -D vitest vite-plugin-doctest
// vitest.config.ts or vite.config.ts (js)
import { defineConfig } from 'vitest/config'; // or `import { defineConfig } from 'vite';`
import { doctest } from 'vite-plugin-doctest';
export default defineConfig({
  plugins: [doctest({ /* options */ })],
  test: {
    includeSource: [
      './src/**/*.[jt]s?(x)',
      './**/*.md', // You can disable markdown test by removing this line
    ],
  },
});
npx vitest

Options

Currently, there is no option.

type Options = {}

How it works

This plugin will transform your documentation tests.

This transformation occurs only when you start Vitest. So, you don't need to worry about the performance of your production code.

/**
 * @example
 * ```ts @import.meta.vitest
 * expect(add(1, 2)).toBe(3);
 * ```
 */
export function add(a: number, b: number) {
  return a + b;
}

/**
 * @example
 * ```ts @import.meta.vitest
 * expect(add(1, 2)).toBe(3);
 * ```
 */
export function add(a: number, b: number) {
  return a + b;
}

if (import.meta.vitest) {
const {assert,chai,createExpect,expect,getRunningMode,isWatchMode,should,vi,vitest} = import.meta.vitest;
import.meta.vitest.test("1+2=3", async () => {
expect(add(1, 2)).toBe(3);
});
}

Constraints

This plugin has some constraints.

  • You cannot use typechecks. (e.g. expectTypeOf, assertType, etc...)
  • You cannot use lifecycle hooks. (e.g. beforeEach, afterAll, etc...)
  • Currently you cannot use import statement in your test code. (You can use dynamic import)
  • and more... (Please make an issue if you find it)
