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 🙏

Readme

chat-vue-storage

一、简介

提供数组数据的分页读写,及自定义配置。

二、如何使用

安装 install

    yarn add chat-vue-storage / npm i chat-vue-storage

导入 import

    import ListStorage  from 'chat-vue-storage'

使用

  1. 创建实例并传入配置对象:
    const messageListStorage = new ListStorage({
        saveKey: 'chat-vue-history', // 存储的key
        pageSize: 10, // 分页大小
        maxSize: 100, //最多存储数组的长度
    })

配置对象也可不传,这时候会使用默认的配置:

    {
       saveKey: 'chat-vue-history',
        pageSize: 10,
        maxSize: 100,
    }
  1. 读写数据:
    // 存储数组数据,写入成功返回更改后的数组长度,否则返回-1
    // arrData 必选 Array|Object, 必须长度大于0的对象数组或对象
    messageListStorage.addData(arrData)
    // 按分页读取数据
    // pageIndex 可选 Number,不传默认为 1
    // 需要注意的是返回分页内容是按照从后往前分页的,适用于加载历史消息数据等场景。
    messageListStorage.getData(pageIndex)
  1. 更新/添加属性:
    // 为列表中的一项更新/添加属性,更新/添加成功返回更新后的项,否则返回undefined
    // id 必选 String, 需为标示该项的唯一值
    // attrName 必选 String, 要设置的属性名
    // attrName 必须 Any, 要设置的属性值
    messageListStorage.update(id,attrName,attrValue)
