node-cache VS uuid

4. node-cache

One such implementation if you are using nodejs is `node-cache` https://github.com/node-cache/node-cache/blob/master/README.md. However you can probably find an implementation for most any language you are using.

In-process caching may be implemented in a Node.js application through libraries, such as node-cache, memory-cache, api-cache, and others. There is a wide variety of distributed caching solutions, but the most popular ones are Redis and Memcached. They are both in-memory key-value stores and optimal for read-heavy workloads or compute-intensive workloads due to their use of memory rather than the slower on-disk storage mechanisms found in traditional database systems.

If you're looking for a caching library, there are several of them in every language I've ever used. For example, in Node node-cache is very popular (https://github.com/node-cache/node-cache). Every language I've ever worked in has a few of these. They tend to have a pretty similar basic feature set, and they all have at least the same functions that you defined in your project.

I got this error when using a library with ECMAScript Module (ESM), such as [udid](https://github.com/uuidjs/uuid):

It has been decided to use uuid Version 4 for all of them. Noteworthy is the CommentId, which serves as the identifier for entities within the boundary, meaning local identifiers. For this case, there is no necessity to use uuid. Evans used positions such as front-left, rear-left, front- right, and rear-right to identify the wheels of a car. However, unlike wheels, no straightforward, real-world, understandable means of identification for CommentId came to my mind, so the uuid framework was adopted as a convenient and easy generation method.

.husky: Git hooks are custom scripts that run in response to some event (e.g. before a commit is created), and they can choose to abort that event under certain conditions. One of their main drawbacks though is that they live inside the .git folder, which means they cannot be directly versioned like the rest of the project. This folder is used by the popular Husky package that makes it possible to include Git hooks with your project and it takes care of installing them to their appropriate location so they can be detected by Git. Example from uuid.

Some popular npm packages for generating UUIDs in JavaScript are the uuid and short-uuid packages.

My first thought is to use something like https://github.com/uuidjs/uuid

activePlayers is a map of unique player IDs (determined by clients via uuid to timestamps of when they last made a GET https://farmhand.vercel.app/api/get-market-data?room=global request. Each time the function is invoked, it examines the map to see which timestamps are older than the HEARTBEAT_INTERVAL_PERIOD (currently 10 seconds) and deletes any that are expired. This data is returned to the client and also written back to Redis to be persisted across function invocations. This is how the active room participants are tracked.

By default Next.js uses nanoid to produce build ids so I used that too. You don't have to use it, there are other options, such as uuid.

You need to include some third-party libraries such as CometChat Widget, Uuid, Validator, Firebase via CDN because you are building the Javascript chat app. Therefore, npm should not be used here. You need to add those libraries for some reasons:
