FAQPage Schema

How do I write custom Bazel rules using Starlark for a monorepo?▼

To write custom Bazel rules using Starlark, you must adhere to idiomatic best practices, ensuring granularity and hermeticity for scalable builds. This provides guidance on creating efficient rules tailored for complex monorepo projects.

Why does my Bazel build system have slow performance in a large monorepo?▼

Slow Bazel build performance in large monorepos often stems from inefficient rules lacking proper granularity. This Skill helps identify and refactor these rules, applying performance tuning strategies to speed up build times significantly.

What is hermeticity and why is it important for Bazel remote execution?▼

Hermeticity ensures builds are self-contained and unaffected by external environment changes, which is crucial for reliable remote execution. This Skill enforces hermeticity principles alongside Bzlmod to maintain efficient and compatible build environments.

Can I use Bzlmod to manage dependencies for complex projects?▼

Yes, you can use Bzlmod to manage dependencies for complex projects by adhering to modern Bazel principles. This Skill requires adherence to Bzlmod principles to ensure efficient and scalable builds across large codebases.

What's the best way to optimize Bazel build performance for a Java project?▼

The best way to optimize Bazel build performance for a Java project is by refactoring inefficient rules and applying performance tuning strategies. This Skill provides expert guidance to identify bottlenecks and ensure compatibility with remote execution.
