React, but make it homemade
Build Your Own React
DIY React tutorial has devs swooning and skeptics side‑eyeing
TLDR: A hands-on guide shows how to rebuild React in simple steps using modern features, making the framework feel approachable. Comments gush over the slick, interactive presentation, with a small chorus asking “but why?”—the takeaway: learning the internals matters, and this tutorial makes it fun and accessible.
Move over, mysterious frameworks—this guide says you can rebuild the popular website tool React yourself, step by step, like a cooking show for code. It’s based on React 16.8, which introduced “hooks” (a simpler way to manage behavior without old-school classes), and walks through friendly bits like making elements, rendering to the page, and even the spooky-sounding “fibers” (think: a careful to-do list for the browser). There’s a self-contained write-up and the code in the Didact repo, plus a talk for the visual learners. The vibe: approachable, clever, and very “you got this.”
The crowd went full heart-eyes for the presentation. One fan cheered it as “amazing,” while another compared it to the legendary annotated Backbone docs—except interactive, which had people posting “hold my coffee, I’m building React tonight.” Jokes flew about “React Lite” and “React you can bring home to mom,” while a small but feisty camp asked the classic: do we really need yet another “rewrite React” tutorial? Cue playful sparring between cheerleaders and pragmatists. Still, the dominant mood was learn-and-chill: demystify the magic, peek behind the curtain, and feel smarter by dinner. If coding tutorials were concerts, this one got a standing ovation—and a few well-timed memes.
Key Points
- •The tutorial rebuilds a minimal version of React aligned with React 16.8 to use hooks and exclude class components.
- •JSX is transformed to JavaScript via createElement calls, typically using tools like Babel.
- •React.createElement outputs element objects with type and props, where props includes children forming trees.
- •Rendering is demonstrated by manually creating DOM nodes, assigning props, creating text nodes for string children, and appending to the container.
- •Planned implementation steps include createElement, render, fibers, render/commit phases, and function components.
