    Koa-OAI-Router

    Koa-OAI-Router

    Koa Router, based on OpenAPI, Swagger and Json Schema

    I have used Markdown and wiki to manage API doc, from which I have suffered a lot. It wastes too much time and is very boring. The document should be repaired when you change the API. It's very inconvenient to test and debug. The management of API doc totally depends on people. As a result, it is hard to make documents have high quality. Meanwhile, the developers will spend more time on testing, which may have a bad effect on the project.

    LaVague

    LaVague

    Framework for building AI agents that automate complex web tasks

    LaVague is an open source framework designed to help developers build AI-powered web agents capable of automating tasks across websites and web applications. It implements the concept of a Large Action Model framework, allowing agents to interpret a user-provided objective and translate it into a sequence of actions performed in a browser. These agents can navigate web pages, retrieve information, fill out forms, and execute multi-step workflows automatically. LaVague is centered around a World Model that analyzes the current webpage state and determines the next set of instructions, combined with an Action Engine that converts those instructions into executable automation code. It can use browser automation tools such as Selenium or Playwright to interact with websites programmatically. Developers can integrate various language models and configure the agent’s reasoning and execution behavior to suit different automation scenarios.

    LangServe

    LangServe

    Helps developers deploy LangChain runnables and chains as a REST API

    LangServe is an open-source deployment framework designed to expose LangChain applications as production-ready REST APIs. The tool simplifies the process of turning language-model pipelines, chains, and agents into web services that can be accessed by external applications. Instead of manually writing API endpoints, developers can use LangServe to automatically generate a server that exposes LangChain workflows through HTTP interfaces. The framework is built on top of FastAPI and uses Pydantic for request validation and structured data handling. It also includes client libraries that allow developers to interact with deployed chains from Python or JavaScript applications. LangServe is commonly used to deploy AI applications such as chatbots, document analysis pipelines, and agent-based systems that require scalable access through APIs.

    MCP Toolbox for Databases

    MCP Toolbox for Databases

    Open source MCP server that exposes database tools for AI agents

    GenAI Toolbox, also known as MCP Toolbox for Databases, is an open source server designed to simplify how generative AI applications interact with databases. It provides a central service that exposes database operations as reusable tools that can be consumed by AI agents and developer workflows. It handles common infrastructure concerns such as authentication, connection pooling, and performance optimization so developers do not have to implement them individually in each application. By defining tools and data sources through configuration files, developers can standardize how AI systems access and operate on database resources. GenAI Toolbox is designed to integrate with agent frameworks and development environments so that AI assistants can execute database-related tasks with proper context and security. It also supports observability through built-in metrics and tracing capabilities, allowing developers to monitor how tools are used and debug interactions.

    MongoDB NodeJS Driver

    MongoDB NodeJS Driver

    The MongoDB Node.js driver

    The MongoDB Node.js driver allows Node.js applications to connect to MongoDB and work with data. The driver features an asynchronous API which allows you to interact with MongoDB using Promises or via traditional callbacks. Whether you are new to MongoDB or you just want to brush up on the core concepts, you can check out the Fundamentals section which features material on using the Node.js driver. The connection URI is the set of instructions that the driver uses to connect to a MongoDB deployment. It instructs the driver on how it should connect to MongoDB and how it should behave while connected. The Authentication Mechanisms guide contains sample connection code using each authentication mechanism supported in the MongoDB Community Edition. The Node.js driver uses the asynchronous Javascript API to communicate with your MongoDB cluster. Asynchronous Javascript allows you to execute operations without waiting for the processing thread to become free.

    OpenPGP.js

    OpenPGP.js

    OpenPGP implementation for JavaScript

    This project aims to provide an Open Source OpenPGP library in JavaScript so it can be used on virtually every device. Instead of other implementations that are aimed at using native code, OpenPGP.js is meant to bypass this requirement (i.e. people will not have to install gpg on their machines in order to use the library). The idea is to implement all the needed OpenPGP functionality in a JavaScript library that can be reused in other projects that provide browser extensions or server applications. It should allow you to sign, encrypt, decrypt, and verify any kind of text, in particular e-mails, as well as managing keys. Version 3.0.0 of the library introduces support for public-key cryptography using elliptic curves. We use native implementations on browsers and Node.js when available.

    PWA

    (WIP) Universal PWA Builder

    PWA is a “universal, framework-agnostic PWA builder” developed by Luke Edwards (lukeed) that aims to let developers scaffold progressive web apps with minimal friction across different view frameworks or libraries. Unlike many CLI tools that target a specific framework (React, Vue, Svelte), this project intentionally tries to remain agnostic, supporting presets for Preact, React, Vue, Svelte and even vanilla JS, while offering all the PWA boilerplate you need (service workers, manifest, offline support) right out of the box. The project is designed for speed of setup: you run pwa init, choose your preset, then pwa build or pwa watch and you get a production-ready bundle with PWA features baked in. The README emphasizes that modern bundlers (Webpack, Rollup) and ecosystem maturity finally allow a universal CLI of this kind, whereas earlier attempts weren’t practical.
