The frontend team at Airbnb has proved there’s no need to dread updating your systems, however, as long as you employ a sound strategy. In their shift from React 16 to 18 Airbnb’s developers created a React Upgrade System, which made it possible to migrate to a new version of the framework with four steps:
- Airbnb’s frontend team avoided risky large-scale upgrades by rolling out changes progressively and gathering feedback.
- Adapting module aliasing and environment targeting allowed to run and test different React versions simultaneously.
- Through comprehensive testing of the unit, integration, and visual regression, developers could deploy the update with full confidence.
- Designing their system to be update-friendly in wait for the release of React 19, means Airbnb’s team made future migrations easier and less demanding for themselves.
