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. -

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! -

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
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. -

json-render is a lightweight, framework-agnostic utility designed to turn JSON data into usable HTML layouts automatically, offering a straightforward way to visualize structured data without writing bespoke template code. It takes deeply nested JSON objects and renders them into intuitive, readable UIs by mapping data types and keys to semantic HTML elements, which helps developers prototype dashboards, debugging tools, or data-driven interfaces quickly. The tool is built to be embeddable in any JavaScript environment — client-side or server-side — without dependencies on a particular frontend framework, making it easy to drop into documentation sites, dev tools, or internal utilities. JSON-Render also supports customization hooks and configuration options so that developers can fine-tune how types are displayed, apply custom styling, and inject interactive behaviors like folding nested sections or filtering keys. -

Angular DataTables
DataTables with Angular
An Angular2+ library for building complex HTML tables using DataTables JQuery plug-in. Implementation of the example on custom filtering with range search. The HTML element provides a Promise that returns the instance of the DataTable. Implementation of the example on individual column searching (text inputs). Sometimes, your DataTable options are stored or computed server-side. All you need to do is to return the expected result as a promise. You can use Angular Pipe to transform data on the table. You can use Angular TemplateRef acquired from ViewChild or passing it from HTML to transform data on the table. -

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 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. -

Default composer
JavaScript library to set default values for nested objects
A tiny (~500B) JavaScript library that allows you to set default values for nested objects. "default-composer" is a JavaScript library that allows you to set default values for nested objects. The library replaces empty strings/arrays/objects, null, or undefined values in an existing object with the defined default values, which helps simplify programming logic and reduce the amount of code needed to set default values. To use "default-composer", simply import the library and call the defaultComposer() function with the default values object and the original object that you want to set default values for. -

Doctrine JSON ODM
An object document mapper for Doctrine ORM using JSON
An Object-Document Mapper (ODM) for Doctrine ORM leveraging new JSON types of modern RDBMS. Did you ever dream of a tool creating powerful data models mixing traditional, efficient relational mappings with modern schema-less and NoSQL-like ones? With Doctrine JSON ODM, it's now possible to create and query such hybrid data models with ease. Thanks to modern JSON types of RDBMS, querying schema-less documents is easy, powerful and fast as hell (similar in performance to a MongoDB database)! You can even define indexes for those documents. Doctrine JSON ODM allows to store PHP objects as JSON documents in modern, dynamic columns of an RDBMS. It works with JSON and JSONB columns of PostgreSQL (>= 9.4) and the JSON column type of MySQL.
