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 🙏

安装

npm install koa-ik-validity --save

测试

npm install & npm test

使用方式

最基本的使用方式

configs/error.js

import table from "koa-ik-validity/table";
export default {
	5000200000: "加载个人中心页失败",
	5000200100: "获取个人基本资料失败",
	// ...
	// 你的错误码配置
	// ...
	...table
};

middlewares/validate.js

import Validity from "koa-ik-validity";
import ERROR_CODE from "../configs/error"
export default Validity((ctx, {code, comment}) => {
	//这里必须return掉,验证都不通过了自然不再继续后续的流程,否则你何苦校验半天
	return ctx.body = {
		code,
		message: `${comment ? `${comment}有误,` : ""}${ERROR_CODE[code]}`
	};
});

app.js

import Koa from "koa";
import body from "koa-bodyparser"; // 如果你不需要做表单处理,完全可以不要
import validate from "../middlewares/validate";
new Koa().use(body()/* 如果你不需要做表单处理,完全可以不要 */, validate({
	query: [
		{
			name: "user", // (必须)接口参数名
			alias: "tel", // (非必需)被校验的方式,默认和参数名一致
			comment: "用户名", // (非必需)用作提示用户(及*写入日志)的参数名,会返回到中间件创建函数参数里。(*写入日志功能不属于这个中间件该做的事情,自己根据提供的返回参数操作)
			required: false, 
			/* (非必需)是否为必须的参数,默认true
			 * 如果你说了false,不必校验,但又偏偏传了这个键值对给服务端,还是会厚脸皮帮你进行校验,否则前端就不要乱传
			 */
		}
	],
	params: [], // 配置同上,不过假设你的接口都没有parmas,参数无效
	body: []// 配置同上,不过假设你的表单都没有被body中间件处理,参数无效
}), yourActionAfterValidatePassed);
