ToAPI

Make Every website provides APIs.

Introduction

Topapi is a supper slight server framework, which provide one way to ask for every website to provide apis.

We don't need to climb the website day by day. Because they should provide the API we need!

All we need is a Temme snippet.

Architecture

Toapi provide multi cache for every page u visit. So, don't worry about u make a huge trivial ddos like to the website.

Demo

Get Started

Install

git clone [e-mail]:yesvods/toapi.git
cd toapi && npm install

Start Example

• Node Require: 8.6+ to support async function

npm start
# then visit localhost:3000/job/3616345 

That's all, can't be simple much more. Read more about example.

NPM

Install the NPM module:

npm install toapi

Usage

Let's say we need to visit the job detail API of lagou.

Such as https://www.lagou.com/jobs/3616345.html

We just write a temme selector like:

...
.job_company@company {
  .fl{find($name|fp, '拉勾认证企业')}
  .c_feature li:nth-child(1){find($domain|fp, '领域')}
  .c_feature li:nth-child(2){find($stage|fp, '发展阶段')}
  .c_feature li:nth-child(3){find($size|fp, '规模')}
  .c_feature li:nth-child(4) a[href=$link];
}
...

If u don't know what temme is. Maybe u can ref this: https://github.com/shinima/temme

And then register it!

const ToAPI = require('toapi')
 
ToAPI.register({
  routeName: '/job/:id',
  matchUrl: 'https://www.lagou.com/jobs/:id.html',
  selector: selector,
})
 
ToAPI.start(3000)

All things are done, enjoy ur website swimming.
