JSONPlaceholder
A simple online fake REST API server
JSONPlaceholder is a free, fake online REST API designed for prototyping, tutorials, and UI demos without standing up a real backend. It provides predictable endpoints for resources like posts, comments, albums, photos, todos, and users with realistic data shapes. Because the data is publicly available and stable, you can build fetch logic, paginate, and render lists while focusing on front-end patterns rather than server plumbing. The API accepts typical HTTP verbs and returns JSON in a consistent format, making it easy to swap with a real server later. It’s widely used in examples, workshops, and automated tests where a dependable dummy service accelerates iteration. With zero setup, it removes a major friction point for learning HTTP clients and front-end data flows. -

The warehouse's SpringBoot-based rights management system
The warehouse's SpringBoot-based rights management system is easy to read and understand, and the interface is simple and beautiful. The core technology uses Spring, MyBatis, and Shiro without any other heavy dependencies. I have always wanted to make a background management system, and I have seen many excellent open source projects but found no suitable ones. So I started to write a background system in my spare time. So there is Zoe. She can be used for all web applications, such as website management background, website member center, CMS, CRM, OA. All front-end and back-end codes are very compact and easy to use after encapsulation, and the probability of errors is low. Also supports mobile client access. The system will continue to update some useful functions. The user is the system operator, and this function mainly completes the system user configuration. Configure the system organization (company, department, group). -

pseudocode.js
Beautiful pseudocode for the Web
pseudocode.js is a JavaScript library that typesets pseudocode beautifully to HTML. Pseudocode.js takes a LaTeX-style input that supports the algorithmic constructs from LaTeX's algorithm packages. With or without LaTeX experience, a user should find the grammar fairly intuitive. The HTML output produced by pseudocode.js is (almost) identical to the pretty algorithms printed on publications that are typeset by LaTeX. Inserting math formulas in pseudocode.js is as easy as LaTeX. Just enclose the math expression in $...$ or \(...\). -

DeckTape
PDF exporter for HTML presentations
DeckTape is a high-quality PDF exporter for HTML presentation frameworks. DeckTape is built on top of Puppeteer which relies on Google Chrome for laying out and rendering Web pages and provides a headless Chrome instance scriptable with a JavaScript API. DeckTape currently supports the following presentation frameworks out of the box. DeckTape also provides a generic command that works by emulating the end-user interaction, allowing it to be used to convert presentations from virtually any kind of framework. The generic mode is particularly useful for supporting HTML presentation frameworks that don’t expose an API or accessible state. DeckTape’s plugin-based architecture exposes an extension API, making it possible to add support for other frameworks or to tailor existing plugins to your specific needs. -

HTMLMinifier
Javascript-based HTML compressor/minifier (with Node.js support)
HTMLMinifier is a highly configurable, well-tested, JavaScript-based HTML minifier. Minifier options like sortAttributes and sortClassName won't impact the plain-text size of the output. However, they form long repetitive chains of characters that should improve compression ratio of gzip used in HTTP compression. SVG tags are automatically recognized, and when they are minified, both case-sensitivity and closing slashes are preserved, regardless of the minification settings used for the rest of the file. HTMLMinifier can't work with invalid or partial chunks of markup. This is because it parses markup into a tree structure, then modifies it (removing anything that was specified for removal, ignoring anything that was specified to be ignored, etc.), then it creates a markup out of that tree and returns it. -

The cutting-edge, browser-first blockchain approach means that users directly connect to the blockchain with nothing more than a browser. Therefore anyone with an up-to-date browser can join the payment network directly, pay and accept payments without having to install software or rely on unnecessary intermediaries. This gives Nimiq its ‘it just works’ characteristic, which is further strengthened by an ethos of simplicity and ease of use. -

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. -

Prerenders static HTML in a single-page application
Flexible, framework-agnostic static site generation for sites and SPAs built with webpack. This is the stable 3.x version of prerender-spa-plugin based on puppeteer. If you're looking for the (now-deprecated) 2.x version, based on PhantomJS, take a look at the v2 branch. The goal of this plugin is to provide a simple prerendering solution that is easily extensible and usable for any site or single-page-app built with webpack. Plugins for other task runners and build systems are planned. Framework-specific examples can be found in the examples/ directory. Most usages of prerender-spa-plugin v2.x should be compatible with v3.x. The exception being advanced configuration options that controlled PhantomJS. These have been replaced by pluggable renderers with their own specific configuration options. -

Turndown
An HTML to Markdown converter written in JavaScript
Convert HTML into Markdown with JavaScript. to-markdown has been renamed to Turndown. See the migration guide for details. For usage with RequireJS, UMD versions are located in lib/turndown.umd.js (for Node.js) and lib/turndown.browser.umd.js for browser usage. These files are generated when the npm package is published. To generate them manually, clone this repo and run npm run build. Turndown also accepts DOM nodes as input (either element nodes, document nodes, or document fragment nodes). Options can be passed in to the constructor on instantiation. The key parameter is a unique name for the rule for easy reference. By default, Turndown does not keep any elements. The filter parameter works like a rule filter. To keep elements that are normally handled by rules, add a rule with the desired behaviour.
