Nativefier
Make any web page a desktop application
Tired of having to search through numerous open tabs on your browser just to view a web page that you regularly view? Make things easier and more convenient for yourself with Nativefier! Nativefier is a command-line tool that easily creates a desktop app for any web site with minimal configuration. It creates an Electron (which uses Chromium under the hood) based native wrapper in an OS executable (.app, .exe, etc) for use on Windows, macOS and Linux. Using Nativefier is absurdly simple. Just type in: nativefier "web site address" to create a native desktop app for your chosen web site, and Nativefier does the rest. It will automatically retrieve the app icon and name, which you can overwrite. -

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
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. -

conf

All you have to care about is what to persist. This module will handle all the dull details like where and how. It does not support multiple processes writing to the same store. I initially made this tool to let command-line tools persist some data. -

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! -

Spectral
A flexible JSON/YAML linter for creating automated style guides
An open-source API style guide enforcer and linter. Why write API Style Guides as lengthy manifestos when you could automate them? Make sure APIs are secure, consistent, and useful. Spectral is open-source but is also baked into Stoplight, with extensions for VS Code and other integration options, giving you real-time feedback wherever you design APIs. Spectral can be used as a generic ruleset engine on any JSON or YAML data but was built with OpenAPI, AsyncAPI, and JSON Schema in mind. Use Spectral rules to target API descriptions for quality improvement or enforce API Style Guide rules, such as naming conventions for OpenAPI models or prohibiting integers in URLs. -

json-render
Generate dashboards, widgets, apps, and data visualizations
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. -

superjson
Safely serialize JavaScript expressions to a superset of JSON
Safely serialize JavaScript expressions to a superset of JSON, which includes Dates, BigInts, and more. At Blitz, we have struggled with the limitations of JSON. We often find ourselves working with Date, Map, Set or BigInt, but JSON.stringify doesn't support any of them without going through the hassle of converting manually. Superjson solves these issues by providing a thin wrapper over JSON.stringify and JSON.parse. For cases where you want lower level access to the json and meta data in the output, you can use the serialize and deserialize functions. -

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. -

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. -

OCRBase
MD/.JSON Document OCR and structured data extraction API
OCRBase is a self-hostable document OCR and structured extraction system built to turn PDFs into machine-usable outputs at scale, aiming to bridge the gap between raw text extraction and production-ready pipelines. Instead of treating OCR as a one-off script, it presents an API-driven workflow where documents are submitted as jobs and processed through a queue-based architecture that can handle high throughput. The core output is designed for downstream automation, producing structured results like JSON according to user-defined schemas while also providing readable formats like Markdown for human review or indexing. It includes real-time job progress updates via WebSockets, which makes it easier to integrate into UIs, dashboards, or ingestion systems where users need feedback on long-running document processing.
