The company also adopted a microservices architecture, breaking down its monolithic application into smaller, independent services that could be developed, deployed, and scaled independently. This approach enabled Netflix to innovate faster, reduce complexity, and improve overall system resilience.
The Frontend Conundrum
As Netflix expanded its streaming service, the company faced a new challenge: building a scalable and responsive frontend that could handle millions of concurrent users. This is where React comes into the picture.
But does Netflix use React?
The short answer is, kind of. Netflix does use React, but not in the way you might think. In 2015, Netflix open-sourced its own UI framework, called Gibbon, which was built on top of React. Gibbon was designed to provide a more performant and efficient way of rendering UI components, taking advantage of React’s virtual DOM.
However, in 2018, Netflix announced that it would be migrating away from Gibbon and towards a more bespoke frontend architecture. This move was driven by the need for greater flexibility and customization, as well as the desire to reduce dependencies on third-party libraries.
The Evolution of Netflix’s Frontend
Today, Netflix’s frontend is built using a custom framework that incorporates elements of React, but also draws on other technologies like GraphQL and WebAssembly. This hybrid approach allows Netflix to achieve optimal performance, scalability, and customization for its unique use case.
One of the key advantages of Netflix’s custom frontend is its ability to optimize for low-latency rendering. By leveraging techniques like server-side rendering and code splitting, Netflix is able to deliver a seamless viewing experience to users, even in areas with limited bandwidth.
A Brief Aside on WebAssembly
WebAssembly (WASM) is a binary instruction format that allows developers to compile code written in languages like C and C++ to run in web browsers. Netflix has been experimenting with WASM to improve the performance of its frontend, using the technology to optimize critical rendering paths and reduce the size of its JavaScript payloads.
The Role of React in Netflix’s Tech Stack
