• Initailization (with custom solver)

  var captchaSolver = {
     solve: function (img, cb) {
        //doSomeCaptchaSolving
        if (err) {
           cb (null, {
              err: err,
              solution: null
           })
           return
        }
          
        cb (null, {
           err: null,
           solution: "solved captcha as string"
        })
     }
  }

• API methods

  • gs.get(searchString, cb) This is an async function which returns a cb with (nullVar, respObj). nullVar is a variable with null value. respObj is an object with following structure :-

    respObj = {
       err: null,
       resp: {}, // a response object from request library. use respObj.resp.body to get the html.
       parsed: {} // parsed html using whacko lib (a fork of cheerio). 
                  // so you can apply css selectors directly.
    }

  • gs.getSync(seachString) This is a sync function which returns 'respObj' as described above.

• Note on callbacks
  The format of callbacks for this API is not (err, resp) but is (nullVar, respObj) where err is a property of respObj. This is because I have used deasync lib which throws err if (err, resp) format is used for the callback which make the code to break. Error handling is more easier as we can use if syntax instead of try catch.
