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&使用

npm install node-cnblogs-spider --save
var ncs = require('node-cnblogs-spider')
ncs([
	http://xxxx,
	http://xxxx
])

使用的轮子

var request = require('request');
var toMarkdown = require('to-markdown');
var cheerio = require('cheerio');
var Promise = require('bluebird')

request封装了http请求

to-markdown用来将html转md的轮子

cheerio类似于Sizzle的nodejs的实现

bluebird是对es6种Promise方法的封装与拓展库

nodejs的异常与错误处理需要注意

这两篇文章值得一看:

注意点

使用Promise尽量脱离回调地狱,使得代码可读性更高

html转md格式的轮子还是有缺陷的,不然完美展现出.md

生成本地文件使用的是stream实现,效率更高。但是要注意文件的命名规范。
