Under The Hood ReactJS

Overview:

The document provides an in-depth analysis of the inner workings of React, focusing on both the current Stack reconciler version and the upcoming Fiber version. The author explains the main concepts and approaches by visually representing the code logic in block-schemes. The goal of the Codecrumbs project is to automate the process of learning and documenting complex codebases, making it easier to understand React’s functionality.

Features:

• Detailed Explanation: Breaks down the React codebase into visual block-schemes for easier understanding.
• Stack Reconciler Version: Analyzes React v15.4.2 to explain the workings of the “legacy React.”
• Fiber Version: Provides insights into React v16 and the advancements introduced in React Fiber.
• Interactive Schemes: Schemes are clickable and can be opened in a new tab for a closer look.
• Continuous Updates: Aiming to cover both Stack and Fiber versions for comprehensive insight into React’s evolution.
• Multilingual Support: Offers translations in Chinese and Korean for a wider audience.

Installation:

To access the detailed breakdown and visual block-schemes of React, follow these steps:

1. Navigate to the github-pages website.
2. Click on the desired part from the list: Intro, Part 0, Part 1, …, Part 14 for Stack reconciler version.
3. For the Fiber version, utilize the js-code-to-svg-flowchart tool (work in progress).

Summary:

The document delves into the intricacies of React, unraveling the workings of both the Stack reconciler and the upcoming Fiber version. By visualizing the code logic in block-schemes, the author simplifies complex concepts for readers. The interactive nature of the schemes and the use of two React versions provide a comprehensive understanding of React’s evolution and advancements. With the promise of continuous updates, the analysis aims to streamline the learning process for developers interested in exploring React’s inner workings.
