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

@totebox/ajax

安装

npm i @totebox/ajax

使用

ESM

import Ajax from '@totebox/ajax';

// simple get request
Ajax(/* REQUEST_URL */);

const ajax = Ajax(/* settings */);
ajax.get(/* REQUEST_URL */);

直接用于 html 中

<script src="./node_modules/@totebox/ajax/dist/ajax.js"></script>
<script>
  $totebox.Ajax(/* REQUEST_URL */);
</script>

API

Ajax(settings)

const ajax = Ajax({
  ...axios.configs,
  interceptors: {
    response(data) {
      ...
      return data.data;
    },
    error(err) {
      ...
      return err;
    },
  },
});

const data = await ajax.get( /* REQUEST_URL */ );

axios configs

参考 axios 配置文档

interceptors

interceptors.response( data, config )

data: 响应对象中的服务端数据

config: axios 的请求配置对象

你应该继续返回一个数据对象,或者 Promise(可以是 rejection 状态):

interceptors: {
  response(data) {
    if (data.status !== 0) {
      return Promise.reject(new Error(data.message || 'Server Error'));
    }
    return data.data;
  },
  ...
},
interceptors.error( err )

err: axios 的请求错误对象。如果一个请求被你 abort 了,该对象还会在它的 response 上设置一个值为 "abort"statusText 属性:

{
  response: {
    statusText: 'abort'
    ...
  },
  message: 'Request abort'
}

你应该继续返回该 err 对象:

interceptors: {
  ...
  error(err) {
    err.message = `Request api error, url: ${err.config ? err.config.url : ''}, message: ${err.message}`;
    return err;
  },
},

Ajax(settings) 的返回对象

  • ajax.get( url [, data [, options ] ] )
  • ajax.post( url [, data [, options ] ] )
  • ajax.delete( url [, data [, options ] ] )
  • ajax.put( url [, data [, options ] ] )
  • ajax.patch( url [, data [, options ] ] )
  • ajax.head( url [, data [, options ] ] )
  • ajax.options( url [, data [, options ] ] )

options 可以单独配置一个请求,和 axios 一致,但对 get、delete、head、options 的参数传递方式做了调整。所有方法都返回 Promise 对象,包括一个可以取消请求的 abort 方法:

...

if (xhr) {
  xhr.abort();
}
xhr = ajax.get(/* REQUEST_URL */);
const data = await xhr;

Ajax(url)

const { data } = await Ajax( /* REQUEST_URL */ );
