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 🙏

nano indexed 是一个简化的 web-indexedDB 方法

Feature

  • gzip 0.3kb, 仅仅是一个工具方法
  • 很好的抽象了 set / get / remove 方法
  • 自动 parse/format 对象
  • 支持 uint8Array 数据结构
  • 支持 autoIncrement
  • 支持 Typescript
  • 完全 Promise 增删查改
  • 兼容没有 indexedDB,使用 localStorage 进行存储
  • 兼容没有 uint8Array 的环境

Use

import { NanoIndexed } from "nano-indexed";

// 主动声明建的例子
const example = async () => {
  const db = NanoIndexed({
    dbName: "my-db",
    store: "user",
    // version?: number; // 版本
    // keyPath?: string; // 自定义对象内容作为 主键
    // autoIncrement?: boolean; // 是否自增主键
    // uint8Array?: boolean; // 是否存储为 unit8Array 数据结构
  });

  // 存储
  await db.set("page", { name: "bobo", age: 20 });

  // 读取
  const data = await db.get("page");

  // 更新部分值
  const nextData = await db.update("page", { name: "dog" });

  // 删除
  await db.remove("page");
};
example();

// 自增类型例子
const autoIncrementExample = async () => {
  const db = NanoIndexed({
    dbName: "my-db",
    store: "user",
    autoIncrement?: boolean; // 自增主键
  });

  // 存储
  await db.set(null, { name: "bobo", age: 20 });

  // 读取, 使用 int id 读取
  const data = await db.get(1);

  // 更新部分值
  const nextData = await db.update(1, { name: "dog" });

  // 删除
  await db.remove(1);
};

autoIncrementExample();
