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-i18n-gen-resources-type

用于生成 i18n 的类型文件和语言 enum;

解决的问题是避免由于翻译文件频繁更新导致每次都要手动更改类型的问题

效果

现有以下结构的 i18n 翻译文件

📦locales
 ┣ 📂en-US
 ┃ ┣ 📜translation.json
 ┃ ┗ 📜translation2.json
 ┗ 📂zh-CN
 ┃ ┣ 📜translation.json
 ┃ ┗ 📜translation2.json

其中 locales/zh-CN/translation.json 的内容如下

{
  "welcome": "你好",
  "nope": "不可以"
}

使用 vite-i18n-gen-resources-type 插件后,将会按照上面的目录结构生成以下俩文件

1. genI18n.resources.d.ts

这个文件的类型描述是根据 zh-CN 目录中文件进行生成的,可以通过 defaultLang 来配置默认查找的目录名称

export interface I18nResourceInterface {
  translation2: {
    welcome2: "不可以2";
  };
  translation: {
    welcome: "你好";
    nope: "不可以";
  };
}

2. genI18nEnum.ts

export enum GenI18nEnum {
  ZH_CN = "zh-CN",
  EN_US = "en-US",
}

结合 i18next

生成这俩文件后,就可以修改 i18next 的 typescript 定义文件 成下面这样的

import { I18nResourceInterface } from "./langs/genI18n.resources";
import "i18next";

declare module "i18next" {
  interface CustomTypeOptions {
    resources: I18nResourceInterface;
  }
}

?为什么不用官网的例子

// import the original type declarations
import "i18next";
// import all namespaces (for the default language, only)
import ns1 from "locales/en/ns1.json";
import ns2 from "locales/en/ns2.json";

declare module "i18next" {
  // Extend CustomTypeOptions
  interface CustomTypeOptions {
    // custom namespace type, if you changed it
    defaultNS: "ns1";
    // custom resources type
    resources: {
      ns1: typeof ns1;
      ns2: typeof ns2;
    };
    // other
  }
}

主要还是觉得麻烦,添加一个 json 就要进来改一下,还不如一劳永逸,另外语言 code 的 ENUM 也是自动生成好。

使用

export default defineConfig({
  plugins: [
    GenI18nTypes({
      //  输入绝对路径
      watchFolder: `${r("src/i18n/locales")}`,
      //  输入绝对路径
      outputFolder: `${r("src/i18n")}`,
    }),
  ],
});

options

type Args = {
  //  需要监听的文件夹路径
  watchFolder: string;
  //  需要输出 type 和 enum 文件的文件夹路径
  //  默认:watchFolder 的父目录
  outputFolder?: string;
  //  是否生成 enum 文件
  //  默认: true
  isGenEnumFile?: boolean;
  //  生成的 type 文件名称
  //  默认:genI18n.resources.d.ts
  typesFileName?: string;
  //  生成的 enum 文件名称
  //  默认:genI18nEnum.ts
  enumFileName?: string;
  //  生成 type 时默认的语言目录名称
  //  默认:zh-CN
  defaultLang?: string;
};
