Mozaik
Easily craft beautiful dashboards
Mozaïk dashboards support multiple devices through the adaptive layout. You can either put your dashboard on a big screen in the open space, or consult it on your smartphone. Mozaïk dashboard comes with 6 themes and makes it easy to develop your own theme. Mozaïk widgets are maintained as separate modules, thus available via mozaik-ext in npm.js. Mozaïk provides a simple way to define your dashboard layout using a grid system. Most extensions need to communicate with APIs. Mozaïk eases this by providing a backend, which handles API calls and pushes data to widgets through websockets. Sometimes, a single dashboard is not enough. Mozaïk allows multiple dashboards with a smooth transition. -

Easily create forwarding domains, redirections, streams and 404 hosts without knowing anything about Nginx. I created this project to fill a personal need to provide users with a easy way to accomplish reverse proxying hosts with SSL termination and it had to be so easy that a monkey could do it. -

Observable Plot
A concise API for exploratory data visualization
Observable Plot is a free, open-source JavaScript library to help you quickly visualize tabular data. It has a concise and (hopefully) memorable API to foster fluency — and plenty of examples to learn from and copy-paste. In the spirit of show don’t tell, below is a scatterplot of the height and weight of Olympic athletes (sourced from Matt Riggott), constructed using a dot mark. We assign columns of data (such as weight) to visual properties (such as the dot’s x), and Plot infers the rest. You can configure much more, if needed, but Plot’s goal is to help you get a meaningful visualization quickly. Plot employs a layered grammar of graphics inspired by Vega-Lite, ggplot2, Wilkinson’s Grammar of Graphics, and Bertin’s Semiology of Graphics. Plot rejects a chart typology in favor of marks, scales, and transforms. Plot can be readily extended in JavaScript, whether to define a channel, a transform, or even a custom mark. -

OpenAI Assistants Quickstart
OpenAI Assistants API quickstart with Next.js
openai-assistants-quickstart is a template for using the Assistants API in a Next.js app, demonstrating streaming, tool use, and function calling in one place. The repository includes multiple example pages that each showcase specific capabilities, while all examples share the same underlying assistant with all capabilities enabled. The primary chat logic lives in the Chat component at app/components/chat.tsx, which manages rendering, streaming, and forwarding function calls. Server handlers for threads are provided under api/assistants/threads/..., giving a reference for wiring the API into Next.js routes. The Chat component can be copied directly into other projects, along with its styles from app/components/chat.module.css. Example pages include a basic chat, a function calling demo, a file search demo, and a full-featured example, allowing developers to explore each feature in isolation or together. -

Pendulum Editor
A simple markdown editor for static files (Hugo, Nexo, Jekyll
A simple editor for markdown/txt files. Supports saving changes into git repositories hosted anywhere (git add, git commit). Docker images and built binaries are provided. Written by @TitPetric and licensed under the permissive WTFPL. As you write or scroll either the text area or the preview pane, the scroll positions are synchronized based on percentage. In the case of images in the text, accuracy can be quite off, but it's possible to improve this behavior in the future. Most of the development is basically related to the preview of whatever it is you're editing. The editor itself doesn't care about anything other than the contents of the text file you're opening and trying to save. -

Percollate
A command-line tool to turn web pages into beautiful, readable PDF
Percollate is a command-line tool that turns web pages into beautifully formatted PDF, EPUB, or HTML files. By default, percollate processes URLs in parallel. Use the --wait option to process them sequentially instead, with a pause between items. The delay is specified in seconds, and can be zero. By default, percollate bundles all web pages in a single file. Use the --individual flag to export each source to a separate file. Additional CSS styles you can pass from the command line to override styles specified by the default/custom stylesheet. Generate a hyperlinked table of contents. The option is implicitly enabled when bundling more than one web page to a single file. Disable this implicit behavior by passing the --no-to flag. The idea with percollate is to make PDFs that can be printed without losing where the hyperlinks point to. However, for some link-heavy pages, the appended hrefs can become bothersome. -
