Debugování nodu

Debugování node.js aplikace

Nainstalujeme node-inspector modul

npm install -g node-inspector

přepínač -g znamená, že se nainstaluje do /Users/bydga/.nvm/versions/node/v4.2.1/bin/node-inspector

OT: standardní npm install express nainstaluje modul do aktuální složky, do ./node_modules/express
