gsearch-node v0.0.8
var gsearch = require("gsearch-node") var gs = new gsearch({solver: dbc})
- Initailization (with custom solver)
```javascript
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 acb
with(nullVar, respObj)
.nullVar
is a variable withnull
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)
whereerr
is a property ofrespObj
. This is because I have used deasync lib which throwserr
if(err, resp)
format is used for the callback which make the code to break. Error handling is more easier as we can useif
syntax instead oftry catch
.
(function () {
// var deathByCaptcha = require("deathbycaptcha")

var gsearch = require("gsearch-node")
var gs = new gsearch({solver: {}}) // {solver: dbc} for using deathbycaptcha api
