12 | Tegin oma statistikamootori mooduli source avalikuks, selle leiab GitHubist . Täpsemalt näiteks kodeeringute statistika skripti leiab näidete kataloogist
13 |
14 |
15 | Tegu on siis node.js skriptiga. Käivitamisel hakkab skript master protsessiks ning tellib vastava arvu forke kes hakkavad siis etteantud aadresse läbi vaatama. Kui feilib (ühendust ei saada, tundmatu nimi, fork lendab õhku vms.) siis saadetakse veateade Kui õnnestub, siis saadetakse lehe kohta metainfo.
