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-decors

简化koa-router路由书写方法。

使用方法

1. 书写路由文件user.ts;

import { get, put, post, del, patch } from 'koa-router-decors';
class User {
    @get('/user')
    async get(ctx) {
        ctx.body = {
            user: {},
        };
    }
}

2. 加载路由文件

import * as Koa from 'koa';
import { load } from 'koa-router-decors';

const app = new Koa();
app.use(load('/api', 'router_path').routes());
app.listen(9100);

3. 特殊用法

3.1 特殊的路由写法

// 给User类上所有路由添加中间件
@middlewares([setResponseTime])
class User {
    // 一个方法可以生成多个路由;针对特定路由,可以修改前缀,也可以添加中间件
    @get('/method')
    @get('/method', { prefix: '', middlewares: [] })
    async get(ctx: Koa.Context) {
        ctx.body = {
            method: ctx.method,
        };
    }
}

async function setResponseTime(ctx, next) {
    let date = new Date();
    await next();
    ctx.set('X-Response-Time', String(new Date().getTime() - date.getTime()));
}

3.1 特殊的路由加载

const app = new Koa();
// 可以多次调用`load`分别加载不同的目录
app.use(load('/api', `${__dirname}/router/api`).routes());
app.use(load('/web', `${__dirname}/router/web`).routes());
export default app.listen(9100);
