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 🙏

koa-router-namespace

v1.0.0

Published

Add namespace support for koa-router.

Readme

koa-router-namespace

这个模块是对koa-router的增强,增加了namespace功能。通常1个controller里面的route都会有相同的前缀,我比较喜欢将这个前缀抽取出来单独定义,所谓的namespace指的就是这个前缀,这样的话controller里的route就能共享这个namespace。具体用法请往下看。

安装

npm:

$ npm install koa-router-namespace

使用

var koa = require('koa');
var router = require('koa-router');
var namespace = require('koa-router-namespace');

var app = new koa();
app.use(router(app));  // 必须在调用namespace前
namespace(app);  // 给app增加上namespace方法

经过上面的步骤后,app就有了namespace方法,下面是用法:

app.namespace('/users', function() {
	// 匹配 GET /users
	app.get('/', function *() {
		
	})
	
	// path为/时可省略,直接传handler即可
	// 匹配 POST /users
	app.post(function *() {
	
	})
	
	// 匹配 GET /users/:id
	app.get('/:id', function *() {
	
	})
	
	// 匹配 DELETE /users/:id
	app.del('/:id', function *() {
	
	})
	
	// 匹配 PUT /users/:id
	app.put('/:id', function *() {
	
	})
	
	// 支持嵌套
	app.namespace('/:id', function() {
		// 匹配 GET /users/:id/contacts
		app.get('/contacts', function *() {
			
		})
	})
	
	// route method支持数组,这个本身koa-router也是支持的,只是我看他文档没好像没写
	// namespace不支持数组
	// 匹配 GET /users/:id 和 GET /users/:id/profile
	app.get(['/:id', '/:id/profile'], function *() {
	
	})
})

注意事项

  • 必须先绑定上router中间件后,再绑定namespace方法
  • namespace目前只支持String,不支持Array
