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. -

Middy
The stylish Node.js middleware engine for AWS Lambda
Middy is a very simple middleware engine that allows you to simplify your AWS Lambda code when using Node.js. If you have used web frameworks like Express, then you will be familiar with the concepts adopted in Middy and you will be able to get started very quickly. A middleware engine allows you to focus on the strict business logic of your Lambda and then attach additional common elements like authentication, authorization, validation, serialization, etc. in a modular and reusable way by decorating the main business logic. One of the main strengths of serverless and AWS Lambda is that, from a developer perspective, your focus is mostly shifted toward implementing business logic. Anyway, when you are writing a handler, you still have to deal with some common technical concerns outside business logic, like input parsing and validation, output serialization, error handling, etc. -

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.js Telegram Bot API
Telegram Bot API for NodeJS
TelegramBot is an EventEmitter that emits several events. Message, received a new incoming Message of any kind. Depending on the properties of the Message, one of these events may ALSO be emitted, text, audio, document, photo, sticker, video, voice, contact, location, new_chat_members, left_chat_member, new_chat_title, new_chat_photo, delete_chat_photo, group_chat_created, game, pinned_message, poll, dice, migrate_from_chat_id, migrate_to_chat_id, channel_chat_created, supergroup_chat_created, successful_payment, invoice, video_note, etc. Its much better to listen a specific event rather than on message in order to stay safe from the content. Bot must be enabled on inline mode for receive some messages.T elegram only supports HTTPS connections to WebHooks. Therefore, in order to set a WebHook, you will need a SSL certificate. The library makes it easy to get started sending files. By default, you may provide a file-path and the library will handle reading it for you. -

React-Bootstrap
Bootstrap components built with React
React-Bootstrap replaces the Bootstrap JavaScript. Each component has been built from scratch as a true React component, without unneeded dependencies like jQuery. As one of the oldest React libraries, React-Bootstrap has evolved and grown alongside React, making it an excellent choice as your UI foundation. Built with compatibility in mind, we embrace our bootstrap core and strive to be compatible with the world's largest UI ecosystem. By relying entirely on the Bootstrap stylesheet, React-Bootstrap just works with the thousands of Bootstrap themes you already love. The React component model gives us more control over form and function of each component. Each component is implemented with accessibility in mind. The result is a set of accessible-by-default components, over what is possible from plain Bootstrap. -

Wasp
A programming language that understands what a web app is
Wasp (Web Application Specification Language) is a declarative DSL (domain-specific language) for developing, building and deploying modern full-stack web apps with less code. Concepts such as app, page, user, login, frontend, production, etc. are baked into the language, bringing a new level of expressiveness and allowing you to get more work done with fewer lines of code. While describing high-level features with Wasp, you still write the rest of your logic in your favorite technologies (currently React, NodeJS, Prisma). Wasp is in alpha and is therefore likely to change a lot, have bugs and miss important features. Due to its expressiveness, you can create and deploy a production-ready web app from scratch with very few lines of concise, consistent, declarative code. When you need more control than Wasp offers, you can write code in existing technologies such as js/html/css/... and combine it with Wasp code! -

Ziggy
Use your Laravel routes in JavaScript
Ziggy provides a JavaScript route() function that works like Laravel's, making it a breeze to use your named Laravel routes in JavaScript. Ziggy supports Laravel's route-model binding, and can even recognize custom route key names. If you pass route() a JavaScript object as a route parameter, Ziggy will use the registered route-model binding keys for that route to find the correct parameter value inside the object. If no route-model binding keys are explicitly registered for a parameter, Ziggy will use the object's id key. -

bootstrap-select
The jQuery plugin that brings select elements into the 21st century
The jQuery plugin that brings select elements into the 21st century with intuitive multiselection, searching, and much more. Now with Bootstrap 4 support. Bootstrap-select requires jQuery v1.9.1+, Bootstrap’s dropdown.js component, and Bootstrap's CSS. If you're not already using Bootstrap in your project, a precompiled version of the Bootstrap v3.4.1 minimum requirements can be downloaded. If using bootstrap-select with Bootstrap v4+, you'll also need Popper.js. For all of Bootstrap v4's requirements, see Getting started. A precompiled version of the requirements will be made available in an upcoming release of bootstrap-select. Bootstrap 4 only works with bootstrap-select v1.13.0+. By default, bootstrap-select automatically detects the version of Bootstrap being used. However, there are some instances where the version detection won't work. -

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. -

layui
Classic modular front-end UI framework
Created by professional front-end, for full-level front-end and back-end developers, a low-threshold, out-of-the-box front-end UI solution. 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. -
