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 🙏

url 介绍

chem-grid 默认要求使用 axios 来请求数据,在进行组件全局安装时需要将 axios 封装后的实例配置上去

import axiosInstance from './http';

Vue.use({
  httpInstance: axiosInstance
});

如何才能配置 url 让表格获取值? 参照现在常用的 http 管理方式,这里提供了三种场景,尽量满足大家使用

  1. axios 简单封装 - (基础路径、拦截器等...)
  2. 自己封装的函数进行请求
  3. 对接口统一 Schema 配置,对 axios 实现 get,post 等请求封装

1. axios 的简单封装

// 1. 定义axios实例
import axios from 'axios';

const instance = axios.create({
  baseURL: BASE_URL,
  timeout: 20000,
  withCredentials: true
});

instance.interceptors.request.use(config => {
  // ... 请求拦截
});

instance.interceptors.response.use(response => {
  // ... 响应拦截
});

// 2. 在url中使用
const tableConfig = {
  url: '/getUserList'
  // ...
};

2. 自己封装函数

该方式不必在全局安装时配置 httpInstance 选项

import axios from './axiosInstance';
// 1. 自定义请求函数
const getUserList = params => {
  return axios.get('/getUserList', params);
};

// 2. 使用
import { getUserList } from '@/http/UserApi';
const tableConfig = {
  url: getUserList
};

3. 对接口统一 Schema 配置,对 axios 实现 get,post 等请求封装 - 推荐

该方式能更好的管理后端接口,并通过接口 schema 配置来实现更多的功能, 如接口白名单、黑名单等自定义操作

// 1. 接口统一管理 - user.js
export default {
  getUserList: {
    url: '/getUserList',
    type: 'get',
    title: '获取用户列表'
    // ... other set
  }
  // .. other api
};

// 2. axios根据配置 - axiosInstance.js
const http = (name, data) => {
  const targetApi = userConfig[name];
  const params = {
    url: targetApi.url,
    method: targetApi.type
  };
  if (targetApi.type === 'get') {
    params['params'] = data;
  }
  if (targetApi.type === 'post') {
    params['data'] = data;
  }
  return instance(params);
};

// 3. 使用
const tableConfig = {
  url: 'getUserList'
};

修改主题色

@import '~ag-grid-community/src/styles/ag-theme-balham/sass/ag-theme-balham-mixin';

$THEME_COLOR: red; // 定义颜色
.ag-theme-balham {
  @include ag-theme-balham(
    (
      selected-row-background-color: rgba($THEME_COLOR, 0.25),
      range-selection-background-color: rgba($THEME_COLOR, 0.2),
      range-selection-highlight-color: rgba($THEME_COLOR, 0.35),
      range-selection-border-color: $THEME_COLOR
    )
  );

  .chem-grid_handleButtons,
  .chem-grid_base-checkbox,
  .chem-grid_pagination {
    color: ag-param(range-selection-border-color);
  }
}
