    Better BibTeX for Zotero

    Better BibTeX for Zotero

    Make Zotero effective for us LaTeX holdouts

    Better BibTeX (BBT) is a plugin for Zotero and Juris-M that makes it easier to manage bibliographic data, especially for people authoring documents using text-based toolchains (e.g. based on LaTeX / Markdown). Zotero does all its work in UTF-8 Unicode, which is absolutely the right thing to do. Unfortunately, for those shackled to BibTeX and who cannot (yet) move to BibLaTeX, unicode is a major PITA. Also, Zotero supports some simple HTML markup in your items that Bib(La)TeX won’t understand.

    html2canvas

    html2canvas

    A JavaScript HTML screenshot renderer

    html2canvas is a JavaScript HTML renderer. The script provides you with the tools to take screenshots of webpages directly on the browser. The screenshot is based on the DOM and therefore, it may not be 100% accurate to the real representation, given that it is not an actual screenshot, but a type of screenshot built based on the available data and information of the page. The script renders such page as a canvas image, by reading the DOM and the different styles of the featured elements. It doesn't require rendering from the server, given that the image is created on the user's browser. However, as it is heavily dependent on the browser, the library is not to be used in nodejs. It can't circumvent any browser content policy restrictions and to render cross-origin content a proxy will be needed to get the content to the same origin.

    Ajv JSON schema validator

    Ajv JSON schema validator

    The fastest JSON schema Validator

    Security and reliability for JavaScript applications. Ensure your data is valid as soon as it's received. Instead of having your data validation and sanitization logic written as lengthy code, you can declare the requirements to your data with concise, easy to read and cross-platform JSON Schema or JSON Type Definition specifications and validate the data as soon as it arrives to your application. TypeScript users can use validation functions as type guards, having type level guarantee that if your data is validated, it is correct. Ajv was designed at the time when there were no validators fully complying with JSON Schema specification, aiming to achieve the best possibly validation performance via just-in-time compilation of JSON schemas to code. Ajv achieved both speed and rigour, but initially security was an afterthought, many security flaws have been fixed thanks to the reports from its users.

    HTML Anything

    HTML Anything

    The agentic HTML editor

    HTML Anything is an agentic HTML editor that helps local AI agents generate polished HTML artifacts across multiple content formats. It is built for workflows where the user describes a desired output and the agent writes the HTML that can then be previewed, edited, and shipped. The project supports a wide surface area, including magazine layouts, decks, posters, social posts, prototypes, and data-oriented artifacts. It emphasizes local-first creation, reusable design skills, and practical export paths rather than a closed hosted editor model. The repository uses modern web technologies and is positioned as a flexible creative workspace for agent-assisted design. Its value is in turning AI-generated HTML into usable visual deliverables without forcing every project into a traditional design tool.

    JSONView

    JSONView

    A web extension that helps you view JSON documents in the browser

    A web extension that helps you view JSON documents in the browser. Normally when encountering a JSON document (content type application/json), Firefox simply prompts you to download the view. With the JSONView extension, JSON documents are shown in the browser similar to how XML documents are shown. The document is formatted, highlighted, and arrays and objects can be collapsed. Even if the JSON document contains errors, JSONView will still show the raw text. JSONView is a Web extension compatible with Firefox and Google Chrome that helps you view JSON documents in the browser. Once you've got JSONView installed, check out the example JSON file to see the extension in action! If you'd like to contribute to JSONView but don't want to code, consider contributing a translation. Copy the existing localization files from src/_locale and fill them in for your own language, then send a pull request. You can do it all from the GitHub interface. There's not many strings to translate!

    generatedata

    generatedata

    A powerful, feature-rich, random test data generator

    This is the repo for the downloadable version of generatedata.com. The script is essentially an engine to generate any sort of random data in any format. It currently comes with 30 or so Data Types (types of data it generates), 12 Export Types (formats for the data, like CSV, SQL, JSON), plus around 32 data sets for specific countries (city names, regions, etc). But more importantly, it can be extended in any way you want. Check out the developer documentation for more information on that. The current major version of the script is 4.x, which was a big change over earlier releases. Earlier versions were written in PHP and MYSQL and 3.x offered a REST API to let you generate the data programmatically rather than via an API. While this is still planned for 4.x it's not currently offered, and the plan it to tackle that after making the script available as an npm package - which we feel will be a more convenient way to programmatically generate data over the more agnostic REST approach.

    JSON Forms

    JSON Forms

    Customizable JSON Schema-based forms with React, Angular and Vue

    JSON Forms is a declarative framework for efficiently building form-based web UIs. These UIs are targeted at entering, modifying and viewing data and are usually embedded within an application. Writing HTML templates and Javascript for data binding by hand is hard, especially in applications of reasonable size. Furthermore, a form is often more than just a collection of input fields and more advanced functionality is required, e.g. validation or conditional visibility. JSON Forms utilizes the capabilities of JSON and JSON schema and provides a simple and declarative way of describing forms. Forms are then rendered with a UI library or framework, e.g. React or Angular.

    Angular Flex-Layout

    Provides HTML UI layout for Angular applications

    Angular Flex Layout provides a sophisticated layout API using Flexbox CSS + mediaQuery. This module provides Angular developers with component layout features using a custom Layout API, mediaQuery observables, and injected DOM flexbox-2016 CSS stylings. The Flex Layout engine intelligently automates the process of applying appropriate Flexbox CSS to browser view hierarchies. This automation also addresses many of the complexities and workarounds encountered with the traditional, manual, CSS-only application of box CSS. The real power of Flex Layout, however, is its responsive engine. The Responsive API enables developers to easily specify different layouts, sizing, visibilities for different viewport sizes and display devices.

    BSON parser

    BSON parser

    BSON Parser for node and browser

    BSON parser is the core JavaScript implementation of BSON (Binary JSON), the data format used by MongoDB to represent documents on the wire and in storage. It provides encoding and decoding capabilities so JavaScript environments like Node.js and browsers can serialize rich data structures (including types not native to JSON) into the compact, efficient BSON binary representation used by MongoDB drivers and servers. Value types such as ObjectId, Binary, UTC datetime, Decimal128, and Long are provided as first-class objects, enabling precise representation of data that would otherwise be lossy or awkward in plain JSON. js-bson is designed for performance, with optimized algorithms for reading and writing binary data, minimizing overhead in database operations. Because it’s a foundational building block for MongoDB drivers in JavaScript, the library ensures consistency and compatibility between client applications and the MongoDB server.
