Rainbow Search

A small and simple crawler for SLT's Rainbow Pages.

** This was done for educational purposes. SLT, please don't sue me. :c **

Installation

  npm install rainbow-pages --save

Usage

 
  var rainbow = require('rainbow-pages');
 
  // Searching using a string
  rainbow('marikar', function(error, records) {
    if(error) throw error;
    fs.writeFile('input.txt', JSON.stringify(records),  function(error) {
      if(error) throw error;
    });
  });
 
  // Searching using an object
  rainbow({
    search: 'marikar',
    address: 'colombo'
  }, function(error, records) {
    if(error) throw error;
    fs.writeFile('input.txt', JSON.stringify(records),  function(error) {
      if(error) throw error;
    });
  });
 
  // Search using a link to the page
  rainbow('http://rainbowpages.lk/embassies/diplomatic-missions-foreign-representatives-in-sri-lanka', function(error, records) {
    if(error) throw error;
    fs.writeFile('input.txt', JSON.stringify(records),  function(error) {
      if(error) throw error;
    });
  });

Notes

The reason as to why searches usually take a while to search is because what this module does is that it crawls the Rainbow Pages and scrapes data off of it. As you can imagine, this isn't really all that efficient, and with SLT's lack of a public API, there's no other way ( The Rainbow Pages android app uses an API, but the data is encoded/encrypted and I didn't spend a lot of time looking into it).

If you want to see more detailed diagnostics data, try adding using the environmental variable "DEBUG=rainbow-pages:" or "DEBUG=".

DEBUG=* node example/rainbow.js
