Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Modest: A fast HTML renderer implemented as a pure C99 library
Project is deprecated in favour of the same developer's lexbor project[0].

Created a performance-focused HTML5 parser for Ruby, trying to be API-compatible with Nokogiri
It supports both CSS selectors and XPath like Nokogiri, but with separate engines - parsing and CSS engine by Lexbor, XPath engine by libxml2. (Nokogiri internally converts CSS selectors to XPath syntax, and uses XPath engine for all searches).

Andreas Kling (of SerenityOS fame) is building a new Linux browser using SerenityOS libraries
An HTML parser, probably the simplest relatively modern example I could find is 1MB https://github.com/lexbor/lexbor (haven't used it, but might look more into it now that I know it exists.)

The State of Web Scraping in 2021
Lazyweb link: https://github.com/rushter/selectolax
although I don't follow the need to have what appears to be two completely separate HTML parsing C libraries as dependencies; seeing this in the readme for Modest gives me the shivers because lxml has _seen some shit_
> Modest is a fast HTML renderer implemented as a pure C99 library with no outside dependencies.
although its other dep seems much more cognizant about the HTML5 standard, for whatever that's worth: https://github.com/lexbor/lexbor#lexbor

Heh, oh, new to the Internet, are you? :-D

What second language to learn after Python?
Well, regarding HTML5, what I've found was libxml (does not support tag-soup HTML5), https://github.com/lexbor/lexbor, for which I was unable to find good documentation ( see https://lexbor.com/docs/lexbor/#dom), Apache Xerces (appears to not support tag-soup HTML5 as well), and Gumbo, which does not appear to be active and to support selectors and XPath (although there are libraries that add that).

You can't parse [X]HTML with regex
I think we've all (mostly?) tried it. It really is the Wild West of the web when you're trying to parse other people's HTML, though.
I've played around with this parser which is extremely quick. https://github.com/lexbor/lexbor

How SerpApi sped up data extraction from HTML from 3s to 800ms (or How to profile and optimize Ruby code and C extension)
I’m glad to have the opportunity to contribute to an open-source project that is used by thousands of people. Hopefully, we will speed up Nokogiri (or XML parser it uses) to match the performance of html5ever or lexbor at some point in the future. 800 ms to extract data from HTML is still too much.

Playwright Web Scraping 2024 - Tutorial
In this tutorial, our main focus will be on Playwright web scraping. So what is Playwright? It’s a handy framework created by Microsoft. It's known for making web interactions more streamlined and works reliably with all the latest browsers like WebKit, Chromium, and Firefox. You can also run tests in headless or headed mode and emulate native mobile environments like Google Chrome for Android and Mobile Safari.

The best testing setup for frontends, with Playwright and NextJS
// playwright.config.ts import { defineConfig } from "@playwright/test"; /** * See https://playwright.dev/docs/test-configuration. */ export default defineConfig({ testDir: "./src/pages", reporter: "list", use: { baseURL: "http://localhost:5432/", }, timeout: process.env.CI ? 10000 : 4000, // ... more options });

Adding standalone or "one off" scripts to your Playwright suite
This means you cannot place test files outside of this directory, which was brought up as a question on Github some time ago. Initially, I thought it would be nice to add another folder in the repo called "scripts", but Playwright does not allow multiple testDir values.

HTML to PDF renderers: A simple comparison
HTML to PDF conversion is a common requirement in modern web applications. It allows users to save web pages, reports, and other content in a format that is easy to share and print. There are many libraries and services available for converting HTML to PDF, each with its own strengths and weaknesses. In this article, we will compare some of the most popular HTML to PDF renderers in Node.js, including Puppeteer, Playwright, node-html-pdf, and Onedoc.

Playwright seems to be a superior library for working with headless browsers than Puppeteer, but I will go with Puppeteer.
