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 🙏

概述

微信小程序页面、组件增强方法。提供 computed,watch,mixins 等功能。

安装

clone 项目,将mp-plus.js放到你的小程序项目里。使用 mp-plus 提供的 api 代替原生页面、组件注册方法。

注册 Page

import { createPage } from "path/to/mp-plus";

createPage({
  // ...
});

注册 Component

import { createComponent } from "path/to/mp-plus";

createComponent({
  // ...
});

特性

计算属性和侦听器

仿照vue的风格实现的computedwatch

示例

import { createPage } from "path/to/mp-plus";

createPage({
  data: {
    a: 1
  },
  computed: {
    b() {
      return this.data.a + 1;
    }
  },
  watch: {
    b(n) {
      console.log(n);
    }
  }
});

方法合并

小程序原生Page的方法放在配置项的根层级下,和页面事件方法混在一起难以阅读。mp-plus仿照vue的风格将方法全部收集到了methods字段里。

示例

import { createPage } from "path/to/mp-plus";

createPage({
  data: {
    a: 1
  },
  methods: {
    test() {
      console.log("hehe");
    }
  }
});

混入 mixin

参考vuemixin机制,在PageComponent之间实现复用的方式。

为什么不使用Component原生的behaviorsbehaviors只能给组件使用,且不能复用自定义的computedwatch

示例

// myMixin.js
export default {
  data: {
    a: 1
  },
  computed: {
    b() {
      return this.data.a + 1;
    }
  }
};

// index.js
import { createPage } from "path/to/mp-plus";
import myMixin from "./myMixin.js";
createPage({
  mixins: [myMixin]
});

// componentA.js
import { createComponent } from "path/to/mp-plus";
import myMixin from "./myMixin.js";
createComponent({
  mixins: [myMixin]
});
