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 🙏

npm 发布方法

    npm set registry http://192.168.1.207:5000
    npm adduser --registry http://192.168.1.207:5000
    npm publish 

Usage

import Fetch from '@hysight/fetch';

// get, delete, etc.
Fetch(url, {
    params: {key: value}
});

// post, put, etc.
// Content-Type -> application/x-www-form-urlencoded | multipart/form-data | application/json 等
Fetch(url, {
    method: 'POST',
    data: {key: value},// Content-Type设置multipart/form-data, data建议可设置object即可,FormData也算可以。|| Content-Type不设置的话,若想上传文件,data必须设置FormData格式
    headers: {
        'Content-Type': 'application/json'
    },
    // timeout?: number,单个api超时(非必填)
})

注意paramsdata 字段是区别当前请求 GET类型POST类型 的方式。

Default Config

hysight-fetch 提供了一些默认的配置可以简化使用时候的操作。


Fetch().default.minorUrl = (url) => url; // 可对纯url部分进行篡改动作,例如动态版本version api
Fetch().default.baseUrl = '';
Fetch().default.headers['Content-Type'] = 'application/x-www-form-urlencoded';
Fetch().default.headers['Authorization'] = '';
// Fetch().default.timeout = 10000; // 默认全局超时10s(非必填)

// 推荐在主入口模块中导入Fetch,并手动指定以上配置
// eg.

// 后缀url部分
Fetch().default.minorUrl = (url) => {

    // 可自定义处理为url增加不同业务处理逻辑方式
    // eg
    console.log('url被变更了', url);
    return url.replace(/\{version\}/g, 'v1');

};

// 前缀协议/ip/端口部分
Fetch().default.baseUrl = 'http://192.168.1.1';
or
Fetch().default.baseUrl = (url) => {

    // return 'http://192.168.1.207:4024';
    console.log('-=-=', Fetch());
    return process.env.NODE_ENV === 'development'
        ? Fetch().use([
            Fetch().proxy(url)('^/hymodel/home', {
                target: 'http://192.168.1.207:4024'
            }),
            Fetch().proxy(url)('^/hymodel/data', {
                target: 'http://192.168.1.207:4020'
            })
            // proxy(url)('^.*', {
            //     target: api.baseUrl
            // })
        ], api.baseUrl)
        : api.baseUrl;

};
Fetch().default.headers['Content-Type'] = 'application/json';
Fetch().default.headers['Authorization'] = localStorage.getItem('token');

// 每次请求都将自动携带 token 和 baseUrl
// Fetch('http://192.168.1.1/users')  ->  Fetch('/users')

Interceptors

为满足请求及响应时的特殊要求,hysight-fetch 提供了两个拦截器。 和默认配置相似,推荐在主入口模块中配置。

请求拦截器

在每个请求发出的时候,都会携带请求配置进入请求拦截器。


// default
Fetch().interceptors.request = function(config) {

    return config;
}

Usage 例如:我只需要给所有的 POST 请求添加 Authorization 字段。 在操作完成后请 务必 返回 config 配置。


Fetch().interceptors.request = function(config) {

    return config.method === 'POST'
        ? Object.assign(
            {},
            config,
            {
                headers: {
                    ...config.headers,
                    'Authorization': localStorage.getItem('token')
                }
            }
        ) : config;
}

响应拦截器

在每个请求响应后,都会携带响应结果进入响应拦截器。


// default
Fetch().interceptors.response = function(response) {

    return response;
    
}

Usage 例如:用户 token 失效,跳转至 /login


Fetch().interceptors.response = function(response) {

    switch(response.data.code) {
        case -1:
            message.error('token失效,请重新登录');
            history.pushState('/login');
            localStorage.clearItem('token');
            return result;
        case ...
    }
}
