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 🙏

适用 antd-pro 的一个国际化文本自动提取生成工具,免去烦人的手写 ID 和在不同 locale 文件跳转。

思路是利用 defaultMessage ,对没有 ID 的编译时自动生成 ID ,并提取到文件中,提供了 json 文件和 Excel 文件互转,可以在注释里手动配置翻译。

使用

安装

yarn

yarn add mes-babel-plugin-intl

npm

npm i mes-babel-plugin-intl

antd-pro

  1. config.ts 配置插件 mes-babel-plugin-intl

    export default defineConfig({
      plugins: [require.resolve('mes-babel-plugin-intl')],
    });
  2. 顶层目录配置 l10n.config.js

    module.exports = {
      middlewares: {
        summary: ['summary?sourcePattern=i18n-messages/**/*.json'],
        process: [
          'fetchLocal?source=locales,skip',
          'metaToResult?from=defaultMessage,to=zh',
          'youdao?apiname=iamatestmanx,apikey=2137553564',
          'reduce?-autoPick,autoReduce[]=local,autoReduce[]=meta',
        ],
        emit: ['save?dest=locales'],
      },
    };
  3. 开发

    import { useIntl } from 'umi';
    
    const App = () => {
      const { formatMessage } = useIntl();
    
      return (
        <div>
          <p>{formatMessage({ defaultMessage: '提交' })}</p>
          <p>{formatMessage({ defaultMessage: '发送' })}</p>
        </div>
      );
    };

    也可以使用注释来配置默认的翻译 (仅使用函数有效) 下面默认 en-US 翻译为 Submit

    import { useIntl } from 'umi';
    
    const App = () => {
      const { formatMessage } = useIntl();
    
      return (
        <div>
          <p>
            {/**
             * @messagge.en-US Submit
             * @messagge.zh-TW 發送
             */
            formatMessage({ defaultMessage: '发送' })}
          </p>
        </div>
      );
    };

    使用 scope

    import { useIntl } from 'umi';
    
    const App = () => {
      const { formatMessage } = useIntl();
    
      return (
        <div>
          <p>
            {/**
             * @message.scope Offer
             * @messagge.en-US Submit
             */
            formatMessage({ defaultMessage: '发送' })}
          </p>
        </div>
      );
    };
  4. 导出 excel 文件

    • mes-intl scan
    • mes-intl transform
  1. 翻译完毕写入 src mes-intl distribute

Plugin

BabelPlugin

利用 defaultMessage 自动生成 ID 。

使用

import { BabelPluginUmiMesIntl } from 'mes-babel-plugin-intl';

配置到 Babel Plugin 里

.babelrc 或者 Webpack


{
  "plugins": [
    [
      BabelPluginUmiMesIntl,
      // options
    ]
  ]
}

配置选项

interface PluginOptions {
  functionNames?: string[]; // 额外的 function ,内置 formatMessage
  componentNames?: string[]; // 额外的 component , 内置 FormattedMessage
  shortcut?:
    | boolean
    | {
        functionName: string;
      }; // 是否启用内置的一个[快捷函数](#hook) ,或者快捷函数的名称
  fileLoc?: boolean; // MessaggeDescriptor 的位置 ,默认 false
  removeDefaultMessage?: boolean; // 是否去除 defaultMessage ,默认 false
}

内置的一个 快捷函数

UmiPlugin

使用

在 config.js 配置 plugins

export default {
  plugins: ['mes-babel-plugin-intl'],

  // 配置选项
  babelPluginMesIntl: {},
};

配置选项

Babel Plugin Options


CLI

提供了一些工具,在 umi 项目里使用默认配置即可

使用流程

不用 atool-l10n 翻译
  1. mes-intl scan
  2. mes-intl transform
  3. mes-intl distribute
使用 atool-l10n 翻译
  1. mes-intl scan
  2. mes-intl t
  3. mes-intl pick
  4. mes-intl distribute

scan

提取目标路径中的所有 .ts|tsx|js|jsx 文件里的数据

mes-intl scan -s src

-s --source

目标路径,默认为 src

-d --dist

输出文件, 默认为 ./i18n-messages/data.json

配置

可以在顶层目录中自定义配置

export interface MessageDescriptor {
  id: string;
  defaultMessage: string;
  filename?: string;
  loc?: SourceLocation;
  translatedMessage?: Record<string, string>;
  [locale: string]: any;
}

export interface PluginOptions {
  functionNames?: string[];
  componentNames?: string[];
  shortcut?:
    | boolean
    | {
        functionName: string;
      };
  fileLoc?: boolean;
  removeDefaultMessage?: boolean;
}

export interface ScanOptions extends PluginOptions {
  // 目录路径
  source?: string;
  // 输出文件
  dist?: string;
  // 自定义数据转换
  convertor?: (store: Map<string, MessageDescriptor>) => any;
}

transform

将 scan 提取到的 json 文件转为 excel 文件,还会将注释里写的翻译合并

-s --source

目标路径,默认为 ./i18n-messages/data.json

-d --dist

输出文件, 默认为 translated.xlsx ,默认目录 l18n.config 的输出目录,一般为 locales

-l --locale

默认 locale ,默认为 zh-CN

pick

将 atool-110n 翻译的 json 数据转为 excel 文件,还会将注释里写的翻译合并

-s --source

目标目录,将提取其中所有 json 数据,默认为 i18n-messages

-d --dist

输出 excel 文件名,默认为 translated.xlsx

t

翻译命令,调用 atool-l10n 翻译

distribute

适用 umi 项目

将 excel 文件翻译的数据放到 src/locales 里

内置快捷函数

import { useCallback } from 'react';
import { useIntl } from 'umi';

export type UsedFormatMessage = {
  (defaultMessage: string, id?: string): string;
  (defaultMessage: string, query: Record<string, any>, id?: string): string;
};

const useFormatMessage = () => {
  const { formatMessage } = useIntl();

  // eslint-disable-next-line react-hooks/exhaustive-deps
  const handleFormatMessage = useCallback(
    ((defaultMessage: string, query: any, maybeId?: string) => {
      const rawId = typeof query === 'string' ? query : maybeId;
      const id = rawId || Date.now() + Math.random().toString(36);

      try {
        const result = formatMessage(
          {
            defaultMessage,
            id,
          },
          typeof query === 'object' ? query : undefined
        );

        return result;
      } catch (err) {
        return defaultMessage;
      }
    }) as UsedFormatMessage,
    [formatMessage]
  );

  return { formatMessage: handleFormatMessage };
};

export default useFormatMessage;
