It covers essential concepts and workflows, including project setup, build rules, and creating hermetic builds. Viewers learn how to effectively manage dependencies, create custom build actions, and leverage Bazel's powerful features to ensure builds only process necessary changes. Project Setup The video begins with setting up a Bazel project, which requires creating a workspace file to define the project's root. The workspace allows Bazel to manage paths and dependencies effectively. Creating Build Rules Next, the presenter illustrates how to create a custom build rule. This involves defining actions that Bazel can perform, along with specifying input and output files to allow Bazel to monitor changes. Using Commands in Bazel The video explains how to use Bazel commands to build projects. Viewers learn how to run build commands and observe the build environment set up by Bazel, such as 'bazel-bin' and output directories. Making Builds Hermetic A critical segment of the video covers making builds hermetic, which ensures that they work across different platforms by explicitly fetching the required tools. Caching and Dependency Management The presenter discusses Bazel's caching mechanism, which saves time by avoiding unnecessary builds. By defining inputs and output dependencies, Bazel intelligently determines what needs to be rebuilt. Extending Build Actions Lastly, viewers learn how to extend build actions by integrating custom tools, demonstrating a simple implementation using Python, and ensuring builds remain compatible across various systems.
