Você pode utilizar o random-chucknorris-facts de duas formas. Como um comando de console (1) ou como um módulo acoplado ao seu projeto (2).
Independente da forma de uso, é imprescindível que a conexão com a internet esteja disponível para o módulo, pois os fatos são carregados de web.
Instalando globalmente, ele irá permitir rodar uma linha de comando que imprime no console um random fact.
Ex:
$ npm -g install random-chucknorris-facts
$ random-chucknorris-facts
Neste caso adicione random-chucknorris-fact as dependências de seu programa e utilize um callback para obter o random fact;
Ex:
var RandomChuckNorrisFacts = require('random-chucknorris-facts');
new RandomChuckNorrisFacts().random(function(fact) {
console.log(fact);
});
