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 🙏

安装

npm install @nova-fe/i18next-cache-backend
# or
yarn add @nova-fe/i18next-cache-backend
# or
pnpm add @nova-fe/i18next-cache-backend

快速开始

import i18next from 'i18next';
import { CacheBackend } from '@nova-fe/i18next-cache-backend';

i18next
  .use(CacheBackend)
  .init({
    backend: {
      loadPath: '/api/{{lng}}/{{ns}}',
      fetchStrategy: 'namespace', // 或 'bulk'
    },
    // 其他 i18next 配置选项
  });

配置选项

基础配置

{
  backend: {
    // API 端点模式
    loadPath: '/api/{{lng}}/{{ns}}',

    // 获取策略: 'namespace' 或 'bulk'
    fetchStrategy: 'namespace',

    // 批量端点 (使用 'bulk' 策略时)
    bulkPath: '/api/all',

    // 缓存设置
    cachePrefix: 'i18next-cache',
    cacheTTL: 24 * 60 * 60 * 1000, // 24 小时

    // 请求选项
    requestOptions: {
      headers: {
        'Authorization': 'Bearer token'
      }
    }
  }
}

获取策略

命名空间策略

一次加载一个命名空间的翻译:

{
  backend: {
    loadPath: '/api/{{lng}}/{{ns}}',
    fetchStrategy: 'namespace'
  }
}

批量策略

单次请求加载所有翻译:

{
  backend: {
    loadPath: '/api/{{lng}}/{{ns}}', // 单个请求的回退选项
    bulkPath: '/api/all',
    fetchStrategy: 'bulk'
  }
}

API 参考

CacheBackend

实现 i18next 后端接口的主要后端类。

配置接口

interface CacheBackendConfig {
  loadPath?: string;
  bulkPath?: string;
  fetchStrategy?: 'namespace' | 'bulk';
  cachePrefix?: string;
  cacheTTL?: number;
  requestOptions?: RequestInit;
}
