    Meteor

    Meteor

    Meteor, the JavaScript App Platform

    Meteor is a full-stack JavaScript framework that streamlines building real-time web and mobile applications from a single codebase. It couples a Node.js backend with a reactive data system so UI updates propagate automatically when data changes. The framework popularized DDP (a lightweight pub/sub protocol) and a client cache (Minimongo) to mirror server collections on the client for latency-compensated interactions. A batteries-included build system, package ecosystem, and opinionated project structure reduce setup time for accounts, methods, publications, and UI integration. Historically paired with Blaze, Meteor also works well with modern front-end libraries like React, Vue, or Svelte for rendering. Its dev experience focuses on hot reloads, rapid prototyping, and predictable data flow, making it attractive for teams that want real-time features without stitching together many separate tools.

    Mocha

    Mocha

    A feature-rich JavaScript test framework running on Node.js

    Mocha is a feature-rich JavaScript test framework running on Node.js and in the browser, making asynchronous testing simple and fun. Mocha tests run serially, allowing for flexible and accurate reporting, while mapping uncaught exceptions to the correct test cases. Hosted on GitHub. Mocha runs in the browser. Every release of Mocha will have new builds of ./mocha.js and ./mocha.css for use in the browser. Mocha is the most-depended-upon module on npm and Mocha is an independent open-source project, maintained exclusively by volunteers. Given Mocha’s use of function expressions to define suites and test cases, it’s straightforward to generate your tests dynamically. No special syntax is required — plain ol’ JavaScript can be used to achieve functionality similar to “parameterized” tests, which you may have seen in other frameworks.

    Node Binance Trader NBT

    Node Binance Trader NBT

    Cryptocurrency trading strategy & portfolio management development

    By default the trader tries to trade with margin, so you need to have at least 0.001 BTC in your spot as well as your margin account. Also, to cover trading fees, you'll need a small amount of BNB in both your spot and margin wallets. While the Bitcoin vs. Altcoins website itself is closed source, the automated trading bot called Node Binance Trader (NBT) is open source. It connects to your Binance account via the Binance API and executes the trades on your behalf. Choose any unique name you like and enter a region. You will then need to retrieve your Binance API keys from Binance. They will need to allow trading and margin wallet access. Heroku only gives dyno's on its free tier 550 hours of run time per month. This is just short of what you will need to keep your new trading bot up and running 24/7. But by simply adding your credit card to your Heroku account your allowance is extended to 1000 hours, which is plenty.

    The warehouse's SpringBoot-based rights management system

    The warehouse's SpringBoot-based rights management system is easy to read and understand, and the interface is simple and beautiful. The core technology uses Spring, MyBatis, and Shiro without any other heavy dependencies. I have always wanted to make a background management system, and I have seen many excellent open source projects but found no suitable ones. So I started to write a background system in my spare time. So there is Zoe. She can be used for all web applications, such as website management background, website member center, CMS, CRM, OA. All front-end and back-end codes are very compact and easy to use after encapsulation, and the probability of errors is low. Also supports mobile client access. The system will continue to update some useful functions. The user is the system operator, and this function mainly completes the system user configuration. Configure the system organization (company, department, group).

    Water.css

    Water.css

    A drop-in collection of CSS styles to make simple websites

    water.css is a “classless” CSS framework that instantly beautifies plain HTML without adding custom classes to your markup. By targeting native HTML elements—headings, paragraphs, forms, tables, and buttons—it applies sensible defaults for spacing, typography, and contrast, producing a clean, readable layout out of the box. The stylesheet is intentionally small and dependency-free, making it a convenient drop-in for prototypes, documentation, and minimalist sites where heavy frameworks are overkill. It includes automatic dark and light themes and exposes CSS variables so you can adjust colors or spacing while keeping the overall aesthetic. Because it respects semantic HTML, it plays well with accessibility tools and reduces the risk of brittle component overrides. The result is a fast path to “good enough” styling that remains easy to customize when a project grows.

    jsdom

    jsdom

    JavaScript implementation of various web standards, for use with Node

    jsdom is a pure-JavaScript implementation of many web standards, notably the WHATWG DOM and HTML Standards, for use with Node.js. In general, the goal of the project is to emulate enough of a subset of a web browser to be useful for testing and scraping real-world web applications. The latest versions of jsdom require Node.js v10 or newer. To use jsdom, you will primarily use the JSDOM constructor, which is a named export of the jsdom main module. Pass the constructor a string. The resulting object is an instance of the JSDOM class, which contains a number of useful properties and methods besides window. In general, it can be used to act on the jsdom from the "outside," doing things that are not possible with the normal DOM APIs. For simple cases, where you don't need any of this functionality, we recommend a coding pattern.

    Classic modular front-end UI framework

Layui (homonym: UI-like) is a front-end UI framework written with its own module specifications, following the writing and organization of native HTML/CSS/JS, with a very low threshold and ready to use. Its exterior is minimalist, but it does not lose its fullness. The volume is light and the components are abundant. Every detail from the core code to the API has been carefully crafted, which is very suitable for the rapid development of the interface. The first version of layui was released in the golden autumn of 2016. It is different from those UI frameworks based on the underlying MVVM.

    telegraf.js

    telegraf.js

    Modern Telegram Bot Framework for Node.js

    Bots are special Telegram accounts designed to handle messages automatically. Users can interact with bots by sending them command messages in private or group chats. These accounts serve as an interface for code running somewhere on your server. Telegraf is a library that makes it simple for you to develop your own Telegram bots using JavaScript or TypeScript. You can see in every example is a Context instance. Telegraf creates one for each incoming update and passes it to your middleware. It contains the update, botInfo, and telegram for making arbitrary Bot API requests, as well as shorthand methods and getters. Telegraf is written in TypeScript and therefore ships with declaration files for the entire library. Moreover, it includes types for the complete Telegram API via the typegram package. While most types of Telegraf's API surface are self-explanatory, there's some notable things to keep in mind.
