Lighthouse can be integrated directly into the Chrome DevTools with its own panel. To run it, you would simply have to select the Lighthouse panel and click on "Generate report". It can also be run from the command line, or as a Node module. -

Koa-OAI-Router
Koa Router, based on OpenAPI, Swagger and Json Schema
I have used Markdown and wiki to manage API doc, from which I have suffered a lot. It wastes too much time and is very boring. The document should be repaired when you change the API. It's very inconvenient to test and debug. The management of API doc totally depends on people. As a result, it is hard to make documents have high quality. Meanwhile, the developers will spend more time on testing, which may have a bad effect on the project. -

With new features released every month, there is bound to be something to get your interactive table juices flowing.

If an input element is used as the filter element, the table will be filtered in real-time as the user types in the input element. To prevent excessive redrawing of the table Tabulator will wait 300 milliseconds after the user has finished typing before triggering the filter. -

Wretch
A tiny wrapper built around fetch with an intuitive syntax
A tiny (~ 3Kb g-zipped) wrapper built around fetch with an intuitive syntax. Wretch is compatible with modern browsers out of the box. For older environments without fetch support, you should get a polyfill. Converts a javascript object to query parameters, then appends this query string to the current url. String values are used as the query string verbatim. Only compatible with browsers that support AbortControllers. Otherwise, you could use a (partial) polyfill. Associates a custom controller with the request. Useful when you need to use your own AbortController, otherwise wretch will create a new controller itself. Aborts the request after a fixed time. If you use a custom AbortController associated with the request, pass it as the second argument. Returns the automatically generated AbortController alongside the current wretch response as a pair. -

Site Kit for WordPress
Site Kit is a one-stop solution for WordPress users
Site Kit is a first-party WordPress plugin that brings key Google services into a single dashboard so site owners can see how their content performs and fix issues without leaving wp-admin. After a guided setup and verification flow, it connects properties to Search Console, Analytics, AdSense, PageSpeed Insights, and other services, surfacing the most relevant metrics per page and per site. The plugin focuses on clarity: traffic sources, search queries, top pages, and monetization signals appear alongside actionable performance recommendations. It also handles authentication and permission scopes securely, so multiple collaborators can access insights without sharing credentials. Widgets and contextual panels put data where it’s needed—for example, on the post list or edit screen—reducing tab-switching. For developers and agencies, Site Kit simplifies client onboarding and standardizes reporting across many sites. -

Modular approach, each metric is generated by a separate "module". phantomas "core" acts as an events emitter that each module can hook into. In-depth metrics such as: number of events bound via jQuery, calls to window.writeor complex and duplicated CSS selectors (via analyze-css). JSON as an output format. Easy integration with other nodejs projects via CommonJS module (see API docs). Metrics can be emitted from the JavaScript code of the page phantomas is run against (thanks to helper functions available in window.__phantomas). Device profiles allow phantomas to emulate mobile or tablet (by setting a proper user agent and viewport). phantomas comes as a CommonJS module that you can use in your nodejs projects. Use grunt to automate daily dev tasks, including your's application web performance. -

jsdom
JavaScript implementation of various web standards, for use with Node
jsdom is a pure-JavaScript implementation of many web standards, notably the WHATWG DOM and HTML Standards, for use with Node.js. In general, the goal of the project is to emulate enough of a subset of a web browser to be useful for testing and scraping real-world web applications. The latest versions of jsdom require Node.js v10 or newer. To use jsdom, you will primarily use the JSDOM constructor, which is a named export of the jsdom main module. Pass the constructor a string. The resulting object is an instance of the JSDOM class, which contains a number of useful properties and methods besides window. In general, it can be used to act on the jsdom from the "outside," doing things that are not possible with the normal DOM APIs. For simple cases, where you don't need any of this functionality, we recommend a coding pattern. -

Beyond just serving static files, Fenix supports features like automatic port management, optional GZip compression, optional JS/CSS minification, Markdown-to-HTML rendering, and simple server logging — making it more capable than the most minimal style tools.

Linux Dash
A beautiful web dashboard for Linux
Using the 3 bar hamburger icon on each module (widget) on Linux Dash, you can drag and re-arrange them. It is strongly recommended that all linux-dash installations be protected via a security measure of your choice. All of your changes are saved in LocalStorage, so your changes will be preserved permanently on that browser for convenience. Each of the modules (widgets) on the Linux Dash screen can be minimized to hide it, expanded in one click to maximize it, adjusted to a custom width. These UI features allow you to focus your usage of Linux Dash at any given point to highlight the modules important to you. Linux Dash comes in well under 1MB of source code and only shows data when client browsers request it. Unlike server-side agent processes, Linux Dash does not gather or maintain historical data-sets, allowing its purpose and footprint to remain focused to a smaller surface area. Linux Dash provides many data-points and data visualizations in real-time.
