    Preact

    Preact

    Fast 3kB React alternative with the same modern API

    Preact is a lightweight alternative to React that implements the same core component and hooks model in a tiny footprint. It provides a virtual DOM, diffing, and a familiar Component/JSX API, enabling developers to reuse much of their React knowledge. With preact/compat, many React libraries can be used directly, making migration or code sharing practical in performance-sensitive apps. Its focus on size and speed makes it attractive for embedded widgets, mobile web, and scenarios where initial load must be extremely fast. The library embraces modern patterns like functional components, hooks, and context while keeping the API surface minimal. Tooling integrations and ecosystem packages round out the experience, so teams can ship production apps without sacrificing bundle budgets.

    RESTful API Node Server Boilerplate

    RESTful API Node Server Boilerplate

    A boilerplate for building production-ready RESTful APIs using Node.js

    A boilerplate/starter project for quickly building RESTful APIs using Node.js, Express, and Mongoose. By running a single command, you will get a production-ready Node.js app installed and fully configured on your machine. The app comes with many built-in features, such as authentication using JWT, request validation, unit and integration tests, continuous integration, docker support, API documentation, pagination, etc. The app has a utility ApiError class to which you can attach a response code and a message, and then throw it from anywhere (catchAsync will catch it). Request data is validated using Joi. Check the documentation for more details on how to write Joi validation schemas. In production mode, only info, warn, and error logs will be printed to the console. It is up to the server (or process manager) to actually read them from the console and store them in log files.

    Claudia Bot Builder

    Claudia Bot Builder

    Create chat bots for Facebook Messenger, Slack, Amazon Alexa, etc.

    Claudia Bot Builder helps developers create and deploy chat-bots for various platforms in minutes to AWS Lambda. It simplifies the messaging workflows, automatically sets up the correct web hooks, and guides you through configuration steps, so that you can focus on important business problems and not have to worry about infrastructure code. This code is enough to operate bots for all supported platforms. Claudia Bot Builder automatically parses the incoming messages into a common format, so you can handle it easily. It also automatically packages the response into the correct message template for the requesting bot, so you do not have to worry about individual bot protocols. Claudia Bot Builder doesn't have a stand-alone http server in the background (such as Express, Hapi, etc.), instead it uses API Gateway and it's not trivial to simulate similar environment locally. Deploy it with --version test to create a separate test environment directly in AWS Lambda.

    DC-SDK is based on the open-source project Cesium for the second development of two three-dimensional WebGis application frameworks, the framework optimizes the use of Cesium and adds some additional features, designed for developers to quickly build WebGis applications. Installing with NPM or YARN is recommended and it works seamlessly with webpack. Since the DC framework sets CESIUM_BASE_URL to ./libs/dc-sdk/resources/, you need to copy Cesium-related static resources files: Assets, Workers, and ThirdParty to libs/dc-sdk/resources directory of the project to ensure that the 3D scene can be rendered properly. You can also use DC.baseUrl to set the static resource base related to Cesium.

    Networked-Aframe

    Networked-Aframe

    Web framework for building multi-user virtual reality experiences

    Multi-user VR on the Web. A framework for writing multi-user VR apps in HTML and JS. Built on top of A-Frame. Follow the NAF Getting Started tutorial to build your own example from scratch, including setting up a local server. Networked-Aframe works by syncing entities and their components to connected users. To connect to a room you need to add the networked-scene component to the a-scene element. For an entity to be synced, add the networked component to it. By default the position and rotation components are synced, but if you want to sync other components or child components you need to define a schema. For more advanced control over the network messages see the sections on Broadcasting Custom Messages and Options. Create an instance of a template to be synced across clients. The position and rotation will be synced by default. The buffered-interpolation is added to allow for less network updates while keeping smooth motion.

    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.
