  1. Learn from and network with peers from the industry
  2. Gain insights from case studies of practical implementation, and evaluate ReactJS and React Native for your work
  3. Understand how to run React in production, end-to-end, rather than only build an application with React

Hosted by

A community - for and of - front-end engineers to share experiences with ReactJS, performant apps with React, crafting better User Interfaces (UI) with React and GraphQL ecosystem. ReactFoo also discusses design patterns and user experience. more



A Closer Look at the React Codebase

Submitted Mar 13, 2018

React, as a UI framework, has come a long way since launch. And if it needs to evolve further, a lot of hands could help. Being a JavaScript library, it is essential for all JavaScript developers to understand the internal beauty of what makes React happen.

In this talk, I will take you on a journey through the react codebase. More importantly, we will have a look at the reason behind some of the quirks of the library itself.


Understanding the way a framework has been written internally gives more power to the developer in optimizing the custom code performance. Although there has been numerous changes to the source code, the core flavor remains intact. And it enables to learning how to work with large code bases as well.

Through this talk, I hope to inspire developers to take a look at the source code of the libraries/frameworks that they are currently using. And also to contribute back to the community.

Here are some of the topics that would be covered in the talk.
- Understanding the source code structure
- React Core APIs
- The Reconciler(s)
- DOM renderer
- Synthetic events
- And some quirky tips

The Common Patterns of React Components

The React framework allows you to shape the Component tree in a variety of different ways. The community has been exploring several ways to simplify the management of various tasks and have discovered a set of patterns, now prevalent in libraries such as React Router, React-Motion, Downshift, etc. These are the patterns that really make React fun to use. more
