    scriptc

    scriptc

    TypeScript-to-Native Compiler

    scriptc is a TypeScript-to-native compiler that turns ordinary TypeScript programs into small, self-contained executables. Its default output contains no Node.js runtime, V8 engine, or JavaScript interpreter. The compiler uses the real TypeScript checker, lowers supported code into a typed intermediate representation, and generates native code through LLVM or C. A coverage command explains which statements compile statically and identifies unsupported constructs with precise diagnostics. Optional dynamic mode embeds QuickJS for npm dependencies and loosely typed code while validating values that cross into static code. ...

    OpenNext for Cloudflare

    OpenNext for Cloudflare

    Open Next.js adapter for Cloudflare

    ...It converts server components, API routes, and middleware into Worker scripts, while placing static assets in globally distributed storage for low-latency delivery. The adapter accounts for edge constraints—limited runtime APIs, streaming semantics, and per-request cold starts—so Next.js features remain functional at the perimeter. It integrates with platform primitives like key-value stores and durable/relational options where needed for sessions, caches, or data hydration. The developer workflow mirrors standard Next.js builds, with additional steps to package and deploy to the edge without editing application code. ...

    Codex++

    Codex++

    Codex++ tweak system for the Codex desktop app

    Codex++ is a tweak system for the Codex desktop app that lets users add custom features, fix UI issues, and manage extensions without rebuilding the application. It patches the local Codex installation so a loader runs on startup and loads tweak modules from the user’s data directory. The runtime injects a Tweaks tab into the Codex settings interface, where users can enable, disable, and configure installed tweaks. The project works on macOS and Windows, with platform-specific installation, repair, backup, and update behavior. It includes tools for creating, validating, updating, and safely disabling tweaks when something goes wrong. codex-plusplus is an unofficial customization layer for advanced Codex users who want more control over the desktop experience.

    MobX

    MobX

    A Simple, scalable state management

    ...No special tools are required, the reactivity system will detect all your changes and propagate them out to where they are being used. All changes to and uses of your data are tracked at runtime, building a dependency tree that captures all relations between state and output. This guarantees that computations depending on your state, like React components, run only when strictly needed. There is no need to manually optimize components with error-prone and sub-optimal techniques like memoization and selectors.
