    Signale Library

    Signale Library

    Highly configurable logging library

    Signale is a highly configurable logging library for Node.js applications and packages. It is designed for logging, status reporting, and output rendering in command-line tools and developer workflows. The library provides many default logger types so teams can express states like success, warning, pending, debug, fatal, and completion without building their own formatters. It is also deeply customizable, allowing custom logger types, scopes, streams, labels, badges, colors, and log levels. Signale includes practical features such as timers, sensitive information filtering, string interpolation, TypeScript support, and package-level configuration. Its main value is making terminal output cleaner, more structured, and easier to adapt to different projects.

    Style2Paints

    Style2Paints

    Sketch + style = paints

    style2paints is an AI-assisted colorization system aimed primarily at line art and manga, turning monochrome drawings into colored illustrations with minimal manual effort. It combines automatic color inference with user guidance, letting artists nudge the model using sparse color hints, masks, or style references. The pipeline focuses on preserving line quality while spreading coherent colors and shading across regions that are often ambiguous to purely automatic methods. Iterative refinement is a core workflow: you can add or adjust hints, rerun inference, and progressively converge on a desired palette and lighting. Beyond flat fills, the model attempts plausible shading and highlights so the result feels less like a “paint bucket” and more like a finished illustration. Because it’s built for artists rather than only researchers, the project emphasizes an approachable UI, predictable edits, and reproducible outputs across sessions.

    Hermione

    Browser test runner based on mocha and wdio

    Hermione is a utility for integration testing of web pages using WebdriverIO and Mocha. If you are familiar with WebdriverIO and Mocha, you can start writing and running tests in 5 minutes! You need to install Hermione via npm and add a tiny config to your project. When tests are run one by one, it takes a lot of time. Hermione can run tests in parallel sessions in different browsers out of the box. Running of too many tests in parallel can lead to the overloading of the main process CPU usage which causes degradation in test passing time, so Hermione runs all tests in subprocesses in order to solve this problem.
