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 🙏

EXPLAIN-VALIDATOR

框架交流QQ群:970799055

云函数请求数据校验器,校验器对JSON Schema进行了扩展,主要是本地化错误信息和数据类型转换。

使用方式

在数据使用前对数据进行校验

const explain = require("explain-unicloud");
explain.validator = require("explain-validator"); // 数据校验器

module.exports = class test extends explain.service {
	
	async test(data) {
		let validate = explain.validator.data({
			data: data,
			schema: {
				"type": "object",
				"title": "test.validator",
				"description": "test.validator校验integer",
				"properties": {
					"id": {
						"display": "编号",
						"type": "integer",
						"requiredErrorMessage": "{display}不能为空",
						"minimum": 1,
						"minimumErrorMessage": "{display}最小为{minimum}"
					}
				},
				"required": ["id"]
			}
		});
		if (validate.result.valid) {
			// 将请求参数类型转换为JSON Schema对应类型
			data = validate.data;
		} else {
			throw new Error(validate.errors[0]);
		}
	}
	
}

每项校验属性都可以通过属性+ErrorMessage配置错误信息,例:

|属性|对应错误信息属性| |-- |-- | |required|requiredErrorMessage| |minimum|minimumErrorMessage| |maximum|maximumErrorMessage|

在ErrorMessage中可以使用{PropertyName}得到同级属性的值,例:

{
	"display": "编号",
	"minimum": 1,
	"minimumErrorMessage": "{display}最小为{minimum}"
}

验证失败时将返回错误信息为:编号最小为1
