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 🙏

Readme

tianma-rewrite

build status

对HTTP请求提供请求路径重定向或服务端代理功能。

安装

$ npm install tianma-rewrite

使用

请求重定向

将请求路径重定向为其它路径。如果请求原始路径不满足匹配条件,则不做更改。

var tianma = require('tianma');

tianma(8080)
    .rewrite({
          '/alpha$1': /^\/foo(.*)/,
          '/beta$1': /^\/bar(.*)/
    })
    .use(function *(next) {
        this.response.data(this.request.path);
    });

上例的执行结果如下:

$ curl http://127.0.0.1:8080/foo/x.js?params
/alpha/foo/x.js?params
$ curl http://127.0.0.1:8080/bar/x.js?params
/beta/foo/x.js?params
$ curl http://127.0.0.1:8080/baz/x.js?params
/baz/x.js?params

服务端代理

将请求代理到远程服务器,并转发远程服务器返回的响应。如果远程服务器返回的响应状态码不等于200,则将请求继续交给后续模块处理。

var tianma = require('tianma');

tianma(8080)
    .rewrite({
          'http://remote.com$1': /^(.*)/
    })
    .use(function *(next) {
        this.response.data('fall to the bottom');
    });

上例的执行结果如下:

$ curl http://127.0.0.1:8080/x.js      # 假设remote.com上存在x.js文件
var x;
$ curl http://127.0.0.1:8080/y.js      # 假设remote.com上不存在y.js文件
fall to the bottom

另外,可为远程服务器地址指定IP和端口,指定IP后,远程服务器域名直接解析为指定的IP。

var tianma = require('tianma');

tianma(8080)
    .rewrite({
          'http://[email protected]:1080$1': /^(.*)/
    })
    .use(middleware);
