NDC Conferences: Introduction to Bazel - Xavier Bonaventura - NDC TechTown 2025

Ever wondered why Google’s build tool Bazel makes you pick between fast and correct? In this NDC TechTown talk, Xavier Bonaventura breaks down how the open-source system (born in 2019) uses a Python-like language called Starlark to define C++, Python and Rust libraries, binaries and tests—all while staying multi-platform, scalable and extensible.

This updated spin on his popular Code Dive session shows how Bazel has evolved, why most of its users joined in the last five years, and how you can mix languages, set up custom toolchains and even write your own extensions to tailor builds to your needs.
