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 🙏

vite-plugin-env-command

v1.0.8

获取package.json中scripts里指令上的参数(build:test->test)添加到环境变量中

Readme

Why? 🤔

当我们想去在不用的环境有不用的设置的时候 官方提供的.env .env.test 文件的形式 未免有点太繁琐了

一般不同的环境在打包的指令上会有所不用

我一般习惯这样做 build:test build:pre

这样就可以把指令上的参数 写到 process.env 上去区分

Installation 💿

npm i -D vite-plugin-env-command # yarn add -D vite-plugin-env-command

Options 🎁


/**
 * 获取指令上的参数
 * 
 * @example  yarn start -> undefined
 * @example  yarn start:staging -> 'staging'
*/
getCommandArgv()


/****——————————————————————————**/

interface Options {
  /**
   * 设置在 process.env上的key
   * 可选参数 默认值是 APP_ENV
  */
  key?: 'string'
  /**
   * 指令上为设置参数时的默认值 
   * 可选参数 默认值是 dev
   * @example yarn start -> 'dev'
  */
  defaultEnv?: 'string'
}

SetEnvByCommandArg(options?:Options)

Usage 🚀

在vite.config.ts中设置如下:


import { defineConfig } from 'vite'

import SetEnvByCommandArg, { getCommandArgv } from 'vite-plugin-env-command';

export default defineConfig({
  plugins: [
    SetEnvByCommandArg({
        key: "APP_ENV",
    }),
  ],
})

在package.json设置指令

"scripts": {
  "start": "vite",
  "start:staging": "vite",
  "start:prod": "vite",
  "build": "tsc && vite build",
  "build:test": "tsc && vite build",
  "build:staging": "tsc && vite build",
  "build:prod": "tsc && vite build",
}

在代码里这样获取参数:

// 这样就可以取到指令":"后的参数了 
// yarn build:staging 
// appMode === 'staging'
const appMode = process.env.APP_ENV;
