Cat: I serve every day—serve my tuna, serve my box, serve my nap. 😼

It needs classes and a logger just in case
class CatRetrievalError extends Error {
constructor(message) {
super(message);
this.name = 'CatRetrievalError';
}
}
class Logger {
static instance = null;
static getInstance() {
if (!Logger.instance) {
Logger.instance = new Logger();
}
return Logger.instance;
}
log(message) {
console.log(`[CatSystem Log: ${new Date().toISOString()}] ${message}`);
}
}
class TimeProvider {
getCurrentTime() {
return new Date();
}
}
class CatEmojiFactory {
static createMorningCat() {
return '🐈⬛';
}
static createAfternoonCat() {
return '🐈';
}
}
function logDecorator(target, propertyKey, descriptor) {
const originalMethod = descriptor.value;
descriptor.value = function (...args) {
Logger.getInstance().log(`Entering ${propertyKey} with args: ${JSON.stringify(args)}`);
const result = originalMethod.apply(this, args);
Logger.getInstance().log(`Exiting ${propertyKey} with result: ${JSON.stringify(result)}`);
return result;
};
return descriptor;
}
class CatService {
constructor(timeProvider) {
this.timeProvider = timeProvider || new TimeProvider();
}
@logDecorator
async getCatAsync() {
return new Promise((resolve, reject) => {
try {
setTimeout(() => {
const currentHour = this.timeProvider.getCurrentTime().getHours();
Logger.getInstance().log(`Current hour determined: ${currentHour}`);
if (currentHour < 12) {
resolve(CatEmojiFactory.createMorningCat());
} else {
resolve(CatEmojiFactory.createAfternoonCat());
}
}, 100);
} catch (error) {
reject(new CatRetrievalError(`Failed to retrieve cat: ${error.message}`));
}
});
}
}
class CatObservable {
constructor() {
this.observers = [];
}
subscribe(observer) {
this.observers.push(observer);
}
notify(cat) {
this.observers.forEach(observer => observer(cat));
}
}
const getCat = async () => {
const catService = new CatService();
const catObservable = new CatObservable();
catObservable.subscribe(cat => {
Logger.getInstance().log(`Observer notified with cat: ${cat}`);
});
try {
const cat = await catService.getCatAsync();
catObservable.notify(cat);
return cat;
} catch (error) {
Logger.getInstance().log(`Error: ${error.message}`);
throw error;

Juuri näin. Secret Catservice ja niiden kulkuoikeudet rajoittavat ovien sulkemisen. Paikallisella sopimuksella ulko-ovi pysyy suljettuna vaikka siitäkin lähes päivittäin saa neuvotella.

Cats delivering mail? What a joke😁! The 'catservice' didn't last long as it was 'not efficient'😆!
Correction: it was during the 1870's!😉

the repository is the entity which orchestrates one or more services.
In this context, you can have CatService (interface), CatLocalService (db), and CatRemoteService (server APIs)

Human, here’s the plan...
I’m going to have a nap and when I wake up I expect my 3rd breakfast to be ready!
... and I want fish!...

Wenn im geschäftlichen Schriftverkehr durch einen schlecht gezielten Tastendruck aus einem Car Service ein Cat Service wird, kann es schonmal zu Verwirrungen kommen. #KatzenImBüro #CarService #CatService
