React Render Tracker – a tool to discover performance issues related to unintended re-renders.

React Render Tracker (RRT) presents component’s tree state over the time and an event log related to a selected component (fiber) or its subtree. It doesn't provide a complete state of the components, but the difference between their states. It's not a replacement for React Devtools, but a compliment to it with a focus on investigation of changes in app's component tree (like mounts, updates and unmounts) and their causes.

React Render Tracker v0.6 – Overview & Instructions

Supported React v16.9+ (fully functional for a React development build, but for profiling and production builds it is not capturing some data, see issue #25)

Features:

• The state of component's tree over time including unmounted components (can be hidden by a toggle in the top right corner) and number of updates (re-renders)
• Two types…

This is a Next.js, Tailwind CSS blogging starter template. Version 2 is based on Next App directory with React Server Component and uses Contentlayer to manage markdown content.

Actor-based state management & orchestration for complex app logic. → Documentation

XState is a state management and orchestration solution for JavaScript and TypeScript apps. It has zero dependencies, and is useful for frontend and backend application logic.

It uses event-driven programming, state machines, statecharts, and the actor model to handle complex logic in predictable, robust, and visual ways. XState provides a powerful and flexible way to manage application and workflow state by allowing developers to model logic as actors and state machines.

The fast & forgiving HTML/XML parser.

htmlparser2 is the fastest HTML parser, and takes some shortcuts to get there. If you need strict HTML spec compliance, have a look at parse5.

npm install htmlparser2

A live demo of htmlparser2 is available on AST Explorer.

htmlparser2 itself provides a callback interface that allows consumption of documents with minimal allocations. For a more ergonomic experience, read Getting a DOM below.

import * as htmlparser2 from "htmlparser2";
const parser = new htmlparser2.Parser({
    onopentag(name, attributes) {
        /*
         * This fires when a new

Mammoth is designed to convert .docx documents such as those created by Microsoft Word, Google Docs and LibreOffice and convert them to HTML. Mammoth aims to produce simple and clean HTML by using semantic information in the document, and ignoring other details. For instance, Mammoth converts any paragraph with the style Heading 1 to h1 elements, rather than attempting to exactly copy the styling (font, text size, colour, etc.) of the heading.

There's a large mismatch between the structure used by .docx and the structure of HTML, meaning that the conversion is unlikely to be perfect for more complicated documents. Mammoth works best if you only use styles to semantically mark up your document.

The following features are currently supported:

• Headings.

• Lists.

• Customisable mapping from your own docx styles to HTML For instance, you could convert WarningHeading to h1.warning by providing an appropriate style mapping.

• …

A simple, scalable, and powerful architecture for building production ready React applications.

React is an excellent tool for building front-end applications. It has a diverse ecosystem with hundreds of great libraries for literally anything you might need. However, being forced to make so many choices can be overwhelming. It is also very flexible, you can write React applications in any way you like, but that flexibility comes with a cost. Since there is no pre-defined architecture that developers can follow, it often leads to a messy, inconsistent, and over-complicated codebase.

This repo attempts to present a way of creating React applications using some of the best tools in the ecosystem with a good project structure that scales very well. Based on my experience working with a lot of different codebases, this architecture turns out to be the most effective.

The goal here is to serve…
