BazelCon 2024

In this talk, you'll gain practical insights from our experience migrating Airbnb's web monorepo (which houses millions of lines of TS/JS code) to Bazel, with a focus on preparing NodeJS tooling for remote builds. We developed methods and tooling to trim down input sizes, share the cache between MacOS and Linux, persist caches through remote builds, catch and fix non-deterministic builds, and automatically generate BUILD files from JS/TS code. This helped us create a robust system for adopting Bazel without compromising on developer experience. These insights are designed to help you navigate similar migrations, improve build performance, and reuse builds across platforms.
