    Wasp

    Wasp

    A programming language that understands what a web app is

    ...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!

    Wireflow

    Wireflow

    User flow chart real-time collaborative tool

    ...Unlike static flowchart apps, Wireflow’s interface focuses on quick and intuitive creation of flow diagrams that represent screens and transitions, helping teams prototype and iterate on navigation logic and interaction sequences. It supports real-time collaboration, meaning multiple people can work on the same flow simultaneously, making it useful for distributed teams and remote workshops. Users can drag and drop nodes, connect steps with directed lines, and annotate interactions, producing a visual blueprint for app behavior, website navigation, or feature flows.

    Project Hestia

    Project Hestia

    A grid-based, modular dashboard built entirely from HTML, CSS, and JS

    Project Hestia is a powerful open-source backend framework and runtime that aims to simplify the development of scalable, distributed applications by providing a modular set of core services such as user authentication, permission enforcement, event streaming, and service orchestration. Built with modern application needs in mind, Hestia-Core abstracts common infrastructure concerns so developers can focus on business logic rather than boilerplate integration of third-party services. It supports microservices communication patterns, event-driven data flows, and pluggable components that make it adaptable to various workloads — from internal APIs to high-traffic public endpoints. The platform also includes abstractions for database connectivity, configuration management, and service discovery, making it easier to build fault-tolerant and observable systems.

    Underscore.js

    Underscore.js

    JavaScript's utility belt

    ...It offers map/filter/reduce, deep-cloning, templating, object traversal, function binding, and more, which makes it easier to write concise, expressive code rather than verbose loops and conditional logic. Many other libraries and frameworks (including Backbone) historically depended on or partnered with Underscore for their utility functions. Even though ES6+ and Lodash have overshadowed some of its role, Underscore remains influential and educational for how to design utility APIs.

    A cross-platform framework using Vue.js

    uni-app is a cross-platform framework that lets developers build applications with Vue syntax and deploy them to multiple targets: iOS, Android, web (H5), and a range of mini-program ecosystems. It abstracts platform differences through a unified component and API layer, so most business logic and UI code can be shared across outputs. The tooling includes a CLI, IDE support, and a plugin market that provides native integrations, UI kits, and deployment helpers. Developers can choose between rendering engines and build modes to optimize for performance or compatibility per platform. The framework emphasizes rapid development with live preview, strong documentation, and scaffolds for common app patterns. ...

    crawler

    crawler

    Collection of JS reverse engineering examples for web scraping study

    crawler is a collection of web scraping and JavaScript reverse engineering examples designed for learning how modern websites protect their data and how those protections can be analyzed. It contains many case studies that demonstrate how to analyze and replicate request parameters, cookies, and encryption logic used by real websites. Each directory in the project focuses on a specific target service or scenario, showing how browser network requests and JavaScript code can be studied to reproduce API calls programmatically. Many examples illustrate techniques such as debugging scripts, intercepting requests, analyzing encrypted parameters, and understanding authentication flows. crawler also explores common anti-scraping defenses and demonstrates how developers can examine them through debugging tools and reverse engineering techniques.

    OpenAPI Specification (OAS)

    OpenAPI Specification (OAS)

    Programming language-agnostic interface description for REST APIs

    ...The OpenAPI Specification (OAS) defines a standard, programming language-agnostic interface description for REST APIs, which allows both humans and computers to discover and understand the capabilities of a service without requiring access to source code, additional documentation, or inspection of network traffic. When properly defined via OpenAPI, a consumer can understand and interact with the remote service with a minimal amount of implementation logic. Similar to what interface descriptions have done for lower-level programming, the OpenAPI Specification removes guesswork in calling a service. The OpenAPI Specification (OAS) defines a standard, language-agnostic interface to RESTful APIs which allows both humans and computers to discover and understand the capabilities of the service without access to source code, documentation, or through network traffic inspection.

It allows developers to automate interactions on web applications, desktop software, and mobile devices without needing platform-specific automation logic. Developers can describe tasks such as clicking buttons, filling forms, or extracting information, and the system interprets these commands to interact with the interface accordingly. Midscene.js includes SDKs, scripting options, and integration capabilities that allow automation workflows to be written in JavaScript, TypeScript, or YAML-based scripts. ...

    react-highlight-words

    React component to highlight words within a larger body of text

    ...For advanced scenarios, you can provide a custom findChunks function to control tokenization (e.g., word boundaries or diacritics-aware behavior). The highlight output is easy to restyle via a custom tag (like mark) or inline styles, keeping the visual layer decoupled from the matching logic. Because it’s small and framework-idiomatic, it drops into tables, lists, virtualized scroll areas, and complex UIs without forcing layout changes.
