nest-user-auth
A build for a back end which implements managing users with MongoDB
This project uses NestJS, GraphQL, and MongoDB. This project implements user authentication. It will be easy to add other GraphQL schemas following the same structure. User auth is implemented in this project because it is one of the hardest and most common things to create for an API. The intent of this project is to provide an example of how to integrate all of these technologies together that are in the NestJS documentation (NestJS, GraphQL, MongoDB, Mongoose, Passport, JWT, DotEnv, Joi, Jest) into a working backend. If you recognize an anti-pattern or a better way to do something, please post an issue. It is challenging not to repeat the structure of the models in the GraphQL schema, Mongo schema, and Typescript interfaces. The goal is to have one truth point for the models and extend that data when more data is needed. With NestJS 6.0.0 a code first approach was introduced. This project uses the schema first approach to be language agnostic. -

patch-package
Fix broken node modules instantly
patch-package lets app authors instantly make and keep fixes to npm dependencies. It's a vital band-aid for those of us living on the bleeding edge. Patches created by patch-package are automatically and gracefully applied when you use npm(>=5) or yarn. No more waiting around for pull requests to be merged and published. No more forking repos just to fix that one tiny thing preventing your app from working. You can use --save-dev if you don't need to run npm in production, e.g. if you're making a web frontend. Note that if you want to patch un-hoisted packages you'll need to repeat the setup process for the child package. Also make sure you're in the child package directory when you run patch-package to generate the patch files. Create a hash of your patches before loading/saving your cache. -

react-resizable-panels
React components for resizable panel groups/layouts
react-resizable-panels provides accessible, flexible split-view layouts for React without wrestling low-level pointer math yourself. It models layouts as “groups” of panels separated by resize handles, supporting horizontal or vertical orientation and mixed min/max constraints that prevent panels from collapsing unexpectedly. The library focuses on smooth interactions: dragging, double-clicking to reset, and keyboard resizing for users who rely on accessibility features. It also supports snapping, collapsed states, and layout persistence so your app can remember user preferences between sessions. Because the API is component-based, you can nest groups, render custom panel contents, and style handles to match your design system. Under the hood, it keeps measurement logic reliable across reflows and React 18 rendering patterns, making it suitable for IDE-like UIs, data dashboards, and inspector panes. -

testing-nestjs
A repository to show off to the community methods of testing NestJS
A repository to show off to the community methods of testing NestJS including Unit Tests, Integration Tests, E2E Tests, pipes, filters, interceptors, GraphQL, Mongo, TypeORM, and more! Each folder is a fully functional Nest application on its own. All you need to do after cloning the repository is move into the folder, install the dependencies and test! Or you could just, you know, look at the test on GitHub too, no big deal. I've noticed a lot of people seem to get stuck on testing, and how to do it using the utilities given to us by Nest. Hopefully, with a community-driven repository of tests, it will help others get a better understanding and feel for how to get tests running. This is not necessarily the Nest canonical way to test an application, nor is it the only way in any scenario. I will do my best to show different ways to run tests, but I will more than likely miss certain ways of running the tests, whether it is mocking in a specific way or otherwise. -

tsup
The simplest and fastest way to bundle your TypeScript libraries
tsup is a zero-config TypeScript/JavaScript bundler focused on developer speed and sensible defaults. It builds on extremely fast tooling under the hood to deliver near-instant feedback loops even in large monorepos. The design goal is to let you publish modern libraries without hand-crafting long build scripts: point it at an entry file and it emits multiple targets, formats, and type declarations. It handles common library needs out of the box—like generating both ESM and CJS, bundling assets, and preserving or treeshaking dependencies—while staying flexible through minimal flags. Because it embraces convention over configuration, it’s easy to adopt as a drop-in replacement for heavier bundlers in simple packages, yet it scales when you need custom externals, minification, or watch modes. The result is a practical tool that shortens the path from source to npm-ready output, lowering maintenance cost across many packages in a repo. -

videojs-player
Video.js player component for Vue(3) and React
videojs-player is a modern, framework-agnostic video playback component built on top of Video.js that provides seamless integration with both Vue 3 and React applications. It abstracts the complexity of working directly with Video.js by exposing a unified component interface that handles initialization, configuration, and lifecycle management internally. The library is written in TypeScript and designed to be highly responsive, supporting the majority of Video.js configuration options while adapting them to different frontend frameworks. One of its main strengths is its flexibility, allowing developers to fully customize the player’s control panel, behavior, and interaction patterns through props, slots, and event hooks. It also provides a rich event system that exposes playback states such as play, pause, seek, and ready, enabling fine-grained control over user interactions. -

vscode-chrome-debug
Debug your JavaScript code running in Google Chrome from VS Code
A VS Code extension to debug your JavaScript code in the Google Chrome browser, or other targets that support the Chrome DevTools Protocol. When your launch config is set up, you can debug your project. Pick a launch config from the dropdown on the Debug pane in Code. Press the play button or F5 to start. The extension operates in two modes - it can launch an instance of Chrome navigated to your app, or it can attach to a running instance of Chrome. Both modes require you to be serving your web application from a local web server, which is started from either a VS Code task or from your command line. Using the URL parameter you simply tell VS Code which URL to either open or launch in Chrome. Just like when using the Node debugger, you configure these modes with a .vscode/launch.json file in the root directory of your project. You can create this file manually, or Code will create one for you if you try to run your project, and it doesn't exist yet. -

AI Code Translator
Use AI to translate code from one language to another
AI Code Translator is a web-based tool that leverages AI to translate source code from one programming language to another, making cross-language porting or code conversion significantly easier — useful when migrating codebases, experimenting across languages, or learning how code patterns map across languages. The UI is built with Next.js + TypeScript, plus modern tooling like Tailwind CSS, giving a clean frontend experience where you paste or upload code, select target language, and get output quickly. Because it uses AI under the hood, the translation can handle not just syntax but also adapt idioms or patterns appropriately for the target language (though with the usual caveats around AI output correctness). The project is open-source under MIT license, so you can self-host it, integrate into internal tools, or customize language-options and prompts to match your team’s style or language preferences. -

AI Employe
Create browser automation as if you were teaching a human using GPT-4
Try without Firebase authentication (temporary solution). Our stack consists of Next.js, Rust, Postgres, MeiliSearch, and Firebase Auth for authentication. Please sign up for a Firebase account and create a project. There are several techniques for this, ranging from sending a shortened form of HTML to GPT-3, creating a bounding box with IDs and sending it to GPT-4-vision to take actions, or directly asking GPT-4-vision to obtain the X and Y coordinates of the element. However, none of these methods were reliable; they all led to hallucinations. To prevent GPT from derailing from tasks, we use a technique that is akin to retrieval-augmented generation, but we kind of call it Actions Augmented Generation. Essentially, when a user creates a workflow, we don't record the screen, microphone, or camera, but we do record the DOM element changes for every action (clicking, typing, etc.) the user takes. -

AI PDF Chatbot LangChain is a full-stack template for building conversational agents that can ingest and answer questions about PDF documents. The project demonstrates how to combine LangChain and LangGraph with a vector database to enable retrieval-augmented question answering over user-provided files. It includes both frontend and backend components, making it suitable as a production starting point rather than just a minimal demo. The system parses uploaded PDFs into document chunks, generates embeddings, and stores them for semantic retrieval during chat interactions. It also supports real-time streaming responses and configurable LLM providers, giving developers flexibility in deployment. The repository is designed to be customizable and extensible so teams can adapt it to their own document intelligence workflows. Overall, it functions as a practical reference architecture for building document-aware AI assistants.
