前言
在开发过程中，我们经常会使用 console.log 来输出一些信息，以便于我们调试。但是，当我们的项目越来越大，我们的 console.log 也会越来越多，这时候我们就需要对 console.log 进行管理，以便于我们更好的调试。
- 以埋点为例子，本地开发中，我们一般是通过打印埋点来看是否生效，这时候
埋点日志可能跟其它日志混在一起，我们很难找到我们想要的日志，这时候我们就需要对埋点日志进行管理，以便于我们更好的调试。
logN.success("埋点", "page_click_report", { eventName: "page_click_report", params: { user_id: "linwu", age: "18", height: "171cm", sex: "male", wx: "linwu-hi" } });
- 版本号信息
- 打印请求信息
有时候在混合H5开发的时候，接口并不是走
XHR而是由客户端提供的JSBridge请求，这时候我们就要对log进行一些处理，以便于我们更好的调试。
Log函数
直接copy下面的代码到项目中，可以直接使用,童叟无欺啊亲
type Color = 'primary' | 'success' | 'info' | 'warning' | 'danger' | 'error'; const COLORS: Color[] = ['primary', 'success', 'info', 'warning', 'danger', 'error']; const COLOR_MAP: Record<Color, string> = { primary: '#2d8cf0', success: '#19be6b', info: '#909399', warning: '#ff9900', danger: '#35495E', error:"#FF0000" }; const getColor = (type: Color) => COLOR_MAP[type]; const createLog = <T extends any[]>( fn: (type: Color, ...args: T) => void ): Record<Color, (...args: T) => void> => { return COLORS.reduce((logs, type) => { logs[type] = (...args: T) => fn(type, ...args); return logs; }, {} as Record<Color, (...args: T) => void>); }; const nsLog = (type: Color, ns: string, msg: string, ...args: any[]) => { const color = getColor(type); console.log( `%c ${ns} %c ${msg} %c ${args.length ? '%o' : ''}`, `background:${color};border:1px solid ${color}; padding: 1px; border-radius: 4px 0 0 4px; color: #fff;`, `border:1px solid ${color}; padding: 1px; border-radius: 0 4px 4px 0; color: ${color};`, 'background:transparent', ...args ); }; export const logN = createLog(nsLog); const sLog = (type: Color, msg: string, ...args: any[]) => { const color = getColor(type); console.log( `%c ${msg} ${args.length ? '%o' : ''}`, `color: ${color};`, ...args ); }; export const logS = createLog(sLog); const bLog = (type: Color, msg: string, ...args: any[]) => { const color = getColor(type); console.log( `%c ${msg} ${args.length ? '%o' : ''}`, `background:${color}; padding: 2px; border-radius: 4px; color: #fff;`, ...args ); }; export const logB = createLog(bLog);
