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 🙏

A utility library for handling local data storage and management

Readme

Local Data Utility

一个轻量级的浏览器本地存储工具库,提供了对 localStorage 和 sessionStorage 的统一封装,支持数据类型保持、前缀设置等功能。

功能特点

  • 统一管理 localStorage 和 sessionStorage
  • 自动处理数据类型的序列化和反序列化
  • 支持设置前缀,避免命名冲突
  • 提供完整的 CRUD 操作和批量操作
  • 支持 TypeScript 类型定义

安装

npm install @web-util/local-data

使用方法

基础使用

import { createLocalData } from '@web-util/local-data';

const storage = createLocalData();

// 存储数据
storage.set('key', 'value');
storage.set('number', 42);
storage.set('boolean', true);
storage.set('object', { name: 'test', value: 123 });

// 获取数据
const value = storage.get('key'); // 'value'
const num = storage.get('number'); // 42
const bool = storage.get('boolean'); // true
const obj = storage.get('object'); // { name: 'test', value: 123 }

// 删除数据
storage.remove('key');

// 获取所有数据
const allData = storage.getAll();

// 清空所有数据
storage.clear();

使用 sessionStorage

// 存储到 sessionStorage
storage.set('key', 'value', { type: 'session' });

// 从 sessionStorage 获取
const value = storage.get('key', { type: 'session' });

// 删除 sessionStorage 中的数据
storage.remove('key', { type: 'session' });

// 获取所有 sessionStorage 数据
const allSessionData = storage.getAll({ type: 'session' });

// 清空 sessionStorage
storage.clear({ type: 'session' });

使用前缀

const storage = createLocalData({ prefix: 'myapp_' });

storage.set('key', 'value'); // 实际存储为 'myapp_key'
const value = storage.get('key'); // 自动添加前缀查找

浏览器兼容性

支持所有现代浏览器,需要支持 localStorage 和 sessionStorage。
