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 🙏

wxapp-store

wxapp-store 是一个微信小程序本地数据持久化存储库。

特性:

  • 简洁的 api。
  • 支持 async/await,promise 语法。
  • 支持基础数据类型存储:object、array、string、number、boolean。
  • 支持正则表达式类型存储。
  • 与原生接口保持一致的性能。
  • 提供原生接口之外的功能。

install

yarn add wxapp-store

api

new Store({ async: true, wx: wx });

  • get(key)
  • set(key, value)
  • info()
  • remove(key)
  • clear()
  • keys(exp) 返回所有或根据正则的键。

使用

默认 Store 为异步存储,通过指定配置项 async 来设置。异步存储与同步存储 api 一样,使用异步存储时返回的是 Promise。__注意:__需要关闭 ES6 转 ES5。

const Store = require('wxapp-store');   // 具体路径自己定位,如果使用搭手架就可以这样了
const store = new Store({ wx });        // 必须指定 wx 对象
+ async function() {
    await store.set('a', 1);
    console.log(await store.get('a'));       // 1

    await store.set('b', [1, 2, 3]);
    console.log(await store.get('b'));       // [1, 2, 3]

    await store.set('c', /url=.*/gi);
    console.log(await store.get('c'));       // /url=.*/gi

    console.log(await store.info());

    console.log(await store.keys());         // ['log', 'a', 'b', 'c']
    console.log(await store.keys(/a|b|c/));  // ['a', 'b', 'c']

    await store.remove('c');
    await store.clear();
} ();

在 Wepy 里使用的时候,可以指定 wx 对象为 wepy。

const store = new Store({ wx: wepy });

在 Taro 里使用的时候,可以指定 wx 对象为 Taro。

const store = new Store({ wx: Taro });

其他使用方式一致。
