    Koa

    Koa

    Expressive middleware for node.js using ES2017 async functions

    Koa is a minimal, expressive web framework for Node.js created by the team behind Express, built around modern JavaScript features. Its middleware system uses async functions and an “onion” execution model, producing clean, sequential control flow for request/response handling. Koa keeps the core small and unopinionated—there’s no built-in router or templating—so developers compose only the pieces they need. The framework exposes a refined Context object to standardize request and response utilities without obscuring Node’s primitives. This design encourages readable middleware, robust error handling, and straightforward composition for tasks like authentication, logging, and body parsing. In production, Koa’s simplicity and async-first approach translate to predictable performance and maintainable server code.

    Highly scalable realtime pub/sub and RPC framework

    Highly scalable pub/sub and RPC toolkit optimized for async/await. Pub/sub-channels are very cheap. You can have millions of unique channels without worrying about memory or CPU usage.

The socket cluster CLI tool exposes kubectl (Kubernetes) shortcut commands to make deploying your app to any Kubernetes cluster really easy. All necessary Kubernetes .yaml files are provided. After deploying your app to a Kubernetes cluster, you can scale indefinitely by using the kubectl scale deployment command to add more SCC-worker and SCC-broker instances as needed. You can perform asynchronous operations anywhere along a socket's inbound or outbound stream without any risk of disrupting the message processing order. Awaiting asynchronous actions along a socket's inbound or outbound streams can cause messages to pile up.

Optionally, if the request contains an X-Request-Id header, uses its value instead. Allows to obtain the generated request id anywhere in your routes later and use it for logging or any other purposes.

    electron-store

    Simple data persistence for your Electron app or module

    Simple data persistence for your Electron app or module. Save and load user preferences, app state, cache, etc. Electron doesn't have a built-in way to persist user preferences and other data. This module handles that for you, so you can focus on building your app. You can use this module directly in both the main and renderer process. For use in the renderer process only, you need to call Store.initRenderer() in the main process, or create a new Store instance (new Store()) in the main process. Changes are written to disk atomically, so if the process crashes during a write, it will not corrupt the existing config. Under the hood, the JSON Schema validator ajv is used to validate your config. We use JSON Schema draft-07 and support all validation keywords and formats. You should define your schema as an object where each key is the name of your data's property and each value is a JSON schema used to validate that property.

You'll find as, forwarded, CSS, keyframes, styled and so much more. Easily access your common sizes, colors, and anything really with the use of a theme. On the server, you can easily extract the CSS for the current state with extractCss. The initial thought of goober was a CSS-in-js solution at the cost of peanuts. Hence the peanuts emoji. By using goober, you are practically getting back space in size to build more of the needed features.
