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

@nilswg/use-config

Easy to use and manage your configurations

使用範例

在你當前的專案目錄下,創建一個專門用來放置 config 的目錄。如 ./configurations

./YOUR_PROJECT
   v configurations (在你的專案下創建)
     - config.dev.jsonc
     - config.prod.jsonc
   v src
     - ...
   - package.json

請使用 --config 來傳入環境變數,如下


node ./test.js --config dev
                    //  ^ config variable: dev

使用 useConfig 會根據 --config 的設置取出對應的 config.{env}.jsonc


const config = useConfig({ configDir: "./configurations" });
//    ^ config.dev.json

config 的類型

目前可以支援 json、jsonc、ts 的 config 文件類型,例如:


config.dev.json
config.stage.jsonc
config.prod.ts

但是 config 的名稱不可以重複,例如:

# 💀 下方重複定義的名稱為 dev 的 config

config.dev.json
config.dev.jsonc

configKey

有些情況 --config 可能已經被使用。這時你可以設置 flag configKey delimiter 來避免衝突,例如:


// ✅ node ./test.js $c=dev
const config = useConfig({ flag: '$', configKey: "c", delimiter: "=" });

configName

當然,你也可直接指定 configName,而不是從環境變數中獲取。


const config = useConfig({ configName: "dev" });

推薦的使用方式

當你需要在不同情況下,也能對應上一個預設的 config 文件,你可以設置 defaultConfigName


const config = useConfig({ defaultConfigName: "dev" });

如此一來,預設情況下,沒有從環境中獲取時,他也會將 config.dev.json 作為預選配置。例如:

//@file: ./package.json

{
  "scripts" : {
    "dev": "astro dev",
    "build:local": "astro build",
    "build:staging" : "astro build -- -c staging",
    "build:production" : "astro build -- -c production",
    //                                ^ 使用 -- 隔開
  }
}
