// 直接调用 ajax 方法,可以自由设置任何选项,特殊情况下可以调用

util
import { debounce, throttle, flatten, curry, compose } from '@tangbin/util';

// 数组扁平化
const arr = [1, 2, ['a', [true, false], 'b'], 3];
flatten(arr); // output: [1, 2, 'a', [true, false], 'b', 3]

// 函数柯里化
function add(x: number, y: number, z: number) {
return x + y + z;
}
curry(add)(1)(2)(3); // output: 6
curry(add)(1, 2)(3); // output: 6
// 函数组合
function last(arr: string[]) {

}
function upper(str: string) {

}
const letters = ['a', 'b', 'c'];
compose([upper, last])(letters); // output: C
// 返回 Object.prototype.toString.call(val) = '[object xxx]' 中 xxx 部分的小写形式
typeOf(''); // output: string
typeOf(0); // output: number
typeOf(true); // output: boolean
// 深拷贝
const source = { name: 'aaa', age: 111 };
// 如果确定没有副作用,可以使用这个函数

// 如果有副作用,使用这个函数

hooks - react

查询
// pages/people/detail.tsx
import { useState } from 'react';

// useFetch 和 useFetchWithLoading 用法相同,后者返回4个值,通过 setLoading 触发查询
// const [info, setInfo, loading, setLoading] = useFetchWithLoading
// 根据ID查询数据,value 必填,其他可选
// fetch(url, id, flag)
const [info, setInfo] = useFetch<People>({

// fn: fetch, // fn 默认既是 fetch
value: { name: '', age: -1 },

分页查询

// fn: paging, // fn 默认既是 paging

// 如果使用了 ant design 的表单,可以提供 form 事例用于获取查询参数
form,
// 如果需要手动格式化,可以使用 formatParams 方法

// 通过 setLoading(true) 启动, 或者分页(以及内置)
const onSearch = useCallback(
