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 🙏

v1.0.2

Published

Vitest preset for Taro + React + TypeScript

Readme

@lx-frontend/taro-vitest-preset

面向 Taro + React + TypeScript 项目的可复用 Vitest 预设。

环境依赖

  • 确保项目 node 版本 大于等于 node:22,当前比如在 node:20 低版本可能对 esm 支持不友好,会出现 vscode 插件中运行测试用例失败,而 pnpm test 则无影响。

提供能力

  • createTaroVitestConfig():一键生成推荐默认配置
  • withTaroVitest():与已有 Vitest 配置进行合并
  • 内置 setup 模块:@lx-frontend/taro-vitest-preset/setup
  • 内置 @tarojs/taro@tarojs/components 的 mock
  • 内置覆盖率配置(通过 --coverage 启用)

快速接入

  1. 安装依赖:
pnpm add -D @lx-frontend/taro-vitest-preset vitest @vitest/coverage-v8 @testing-library/react @testing-library/jest-dom @testing-library/user-event jsdom
  1. 创建 vitest.config.ts
import { createTaroVitestConfig } from '@lx-frontend/taro-vitest-preset'

export default createTaroVitestConfig()
  1. 确保 tsconfig.json 包含:
{
  "compilerOptions": {
    "types": ["vitest/globals", "@testing-library/jest-dom/vitest"]
  }
}

脚本配置

package.json 中添加:

{
  "scripts": {
    "test": "vitest run",
    "test:coverage": "vitest run --coverage"
  }
}

与已有配置合并

import { defineConfig } from 'vitest/config'
import { withTaroVitest } from '@lx-frontend/taro-vitest-preset'

export default withTaroVitest(
  defineConfig({
    test: {
      include: ['src/**/*.{test,spec}.ts'],
    },
  })
)
