Bazel
Bazel is an open-source build and test tool developed by Google that provides fast, reliable, and scalable builds for multi-language and multi-platform projects. It uses a declarative language (Starlark) to define build rules and dependencies, enabling reproducible builds and efficient caching to minimize rebuild times. Bazel is designed to handle large codebases with complex dependencies, making it popular in enterprise and open-source environments.
Developers should learn and use Bazel when working on large-scale, multi-language projects that require fast, incremental builds and consistent results across different environments, such as in monorepos or distributed systems. It is particularly valuable for teams needing reproducible builds, efficient dependency management, and support for languages like Java, C++, Python, and Go, as it reduces build times through advanced caching and parallel execution. Use cases include building microservices, mobile apps, or cloud-native applications where speed and reliability are critical.
