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 🙏

使用说明:

npm i killglobal --save

项目中使用:

pages/index/index.js

``

import { getWechat } from "killglobal";

const BasePage = getWechat().page;
const Router = getWechat().router;

Page(BasePage({
    data:{},
    onTapPage1(){ // 跳转到page1
        // 
        /*
            _page_onload_params: 页面启动参数, 同url+params
            _kgData: 额外参数,传到另一个页面的数据,为了防止污染,_kgData会被深拷贝后传到page1页面
            onPage: page1的实例(page1的onLoad被回调时,onPage才会被执行)
        */
        const _page_onload_params = { onload: 'onload' };
        const _kgData = { kgdata: 'kgdata' }
        Router.push('pages/page1/index',_page_onload_params).withKGData(_kgData).onPage(page=>{
            page.showAlert();
            // 执行结果: I'm Page1!
        });
    },
}))

import { getWechat } from "killglobal";

const BasePage = getWechat().page;
const Router = getWechat().router;

    data:{},
    onKGData(data){
        console.log(params);
        // 执行结果: { kgdata: 'kgdata' }
    },

函数介绍

navigateTo —— push页面

getWechat().router.navigateTo(path,options)

getWechat().router.goto(path,options)

getWechat().router.push(path,options)

push 页面
router.navigateTo和另外两个功能一致,为了照顾个人习惯写了另外两个别名:goto、push

参数 :

  • path: string page的路径,绝对或相对路径

  • options: JSON格式的数据 例如:{a: 1, b: 2};,此数据会拼接到path(path?a=1&b=2)后面,在onLoad的入参options中捕获

redirectTo —— 重定向

getWechat().router.redirectTo(path,options)

getWechat().router.redirect(path,options)

push 页面
router.redirectTo和另外1个功能一致,为了照顾个人习惯写了另外1个别名:redirect

参数 :

  • path: string page的路径,绝对或相对路径

  • options: JSON格式的数据 例如:{a: 1, b: 2};,此数据会拼接到path(path?a=1&b=2)后面,在onLoad的入参options中捕获

navigateBack —— 返回

getWechat().router.navigateBack(delta)

getWechat().router.back(delta)

返回 页面
router.navigateBack和另外1个功能一致,为了照顾个人习惯写了另外1个别名:back

参数 :

  • delta: 返回的页面层数,缺省默认未1

reLaunch —— 重启

getWechat().router.reLaunch(path, options)

重启到某个页面

参数 :

  • path: string page的路径,绝对或相对路径

  • options: JSON格式的数据 例如:{a: 1, b: 2};,此数据会拼接到path(path?a=1&b=2)后面,在onLoad的入参options中捕获

跨页面传Object对象

withKGData(obj)

函数: withKGData(obj)
向目标页面传递obj,为了保护数据不受污染,传到下一个页面的obj将被深拷贝,所以在目标页面操作obj不用担心前一个页面的数据收到影响

使用

在当前页面使用

pages/index/index.js

``

import { getWechat } from "killglobal";
const BasePage = getWechat().page;
const Router = getWechat().router;
Page(BasePage({
    data:{},
    gotoTargetPage(data){
        const _obj = {a:1};
        Router.navigateTo('/pages/target/index').withKGData(_obj);
        // Router.redirectTo().withKGData(obj);
        // Router.reLaunch().withKGData(obj);
        // Router.navigateBack().withKGData(obj);
    },
}))

``

在目标页面接收

pages/target/index.js

``

import { getWechat } from "killglobal";
const BasePage = getWechat().page;
Page(BasePage({
    data:{},
    onKGData(data){
        console.log(params);
        // 执行结果: {a:1}
    },
}))

``

跳转前获取目标页面实例 —— onPage

onPage(page=>{})

函数: onPage(page=>{})

使用

在当前页面使用

pages/index/index.js

``

import { getWechat } from "killglobal";
const BasePage = getWechat().page;
const Router = getWechat().router;
Page(BasePage({
    data:{},
    gotoTargetPage(data){
        Router.navigateTo('/pages/target/index').onPage(page=>{
            page.showAlert();
            // 打印结果: I'm target!
        });
        // Router.redirectTo().onPage(page=>{});
        // Router.reLaunch().onPage(page=>{});
        // Router.navigateBack().onPage(page=>{});
    },
}))

``

目标页面

pages/target/index.js

``

import { getWechat } from "killglobal";
const BasePage = getWechat().page;
Page(BasePage({
    data:{},
    showAlert(){
        console.log("I'm target!")
    },
}))

``
